1. Effectiveness of Adjunctive Hyaluronic Acid Application in Surgical Treatment of Gingival Recession Sites

Author: Mattia Manfredini, Mario Beretta, Carlo Maiorana, Marco Tandurella, Federica Eugenia Salina, and Pier Paolo Poli
Subjects: gingival recession, linear hyaluronic acid, cross-linked hyaluronic acid, root coverage procedure, surgical treatment of recession, Medicine
Abstract: The aim of this systematic scoping review was to provide scientific evidence on the efficacy and methods of application of hyaluronic acid (HA) in the coverage of gingival recessions in terms of recession depth (RD) reduction, clinical attachment level (CAL) gain and probing depth (PD). An electronic search of the literature on the main databases was conducted. Initially, 405 articles were identified. Finally, four studies were included after the review process. It was not possible to perform a meta-analysis of the articles selected because of the differences among the surgical treatments and commercial formulations and compositions of HA. Both randomized controlled trials in this research examined type 1 gingival recessions treated with a coronally advanced flap. In the selected case series, recessions were treated with either a modified coronally advanced tunnel or laterally closed tunnel combined with a subepithelial connective tissue graft and HA. No significant variation was found in terms of PD. Modifications of CAL are connected to variations of RD; however, RD reduction is similar to the control group. HA seems to improve the clinical outcomes of gingival recession coverage in the short term, but the magnitude is limited. Formulations, surgical techniques and application methods are heterogeneous.

2. The efficacy of a porcine collagen matrix in keratinized mucosa width augmentation: a 10-year follow-up clinical prospective study

Author: Mattia Manfredini, Pier Paolo Poli, Pierluigi Guerrieri, Mario Beretta, and Carlo Maiorana
Subjects: Collagen matrix, Soft tissue augmentation, Keratinized mucosa, Peri-implant mucosa, Peri-implant soft tissue, Clinical prospective study, Medicine, Dentistry, RK1-715
Abstract: Abstract Purpose The aim of the present study was to evaluate the long-term effectiveness of a xenogeneic collagen matrix (CM) in pre-prosthetic augmentation of the keratinized mucosa width (KMW) at implant sites. Methods All of the patients with localized implant-supported rehabilitation previously treated with vestibuloplasty and KMW augmentation with a non-cross-linked porcine CM were recalled. KMW was measured clinically in an apico-coronal direction from the mucogingival junction to the mucosal margin at the prosthetic zenith of each crown. Measurements were performed clinically by means of a PCP-UNC15 periodontal probe and rounded to the nearest mm. KMW values recorded at 1 year, 5 and 10 years from the soft tissue augmentation procedure were compared using a one-way repeated-measures ANOVA with Bonferroni multiple comparison post-hoc analysis. The level of significance was set at 0.05. Results Measurements were conducted on 13 patients. All implants were in function with no signs of biological complications. All except one implant site showed KMW ≥ 2 mm. KMW decreased significantly from 1 year (3.33 ± 1.11 mm) to 5 years (2.77 ± 0.92 mm) (p = 0.001), and finally remained stable from 5 to 10 years (3.2 ± 0.99 mm) (p = 0.607). From a visual aspect, peri-implant soft tissues were characterized by a good texture and color blending compared to the adjacent teeth, highlighting good integration of the remodeled tissues and stability of the esthetic result. Conclusions The use of a CM in pre-prosthetic soft tissue augmentation at implant sites has proven to be effective in obtaining and maintaining at least 2 mm of KMW around dental implants over a follow-up of 10 years.

3. Full Digital Model-Free Maxillary Prosthetic Rehabilitation by Means of One-Piece Implants: A Proof of Concept Clinical Report with Three-Years Follow Up

Author: Mario Beretta, Mattia Manfredini, Pier Paolo Poli, Sebastian Tansella, and Carlo Maiorana
Subjects: dental implants, digital dentistry, one-piece implants, implant-abutment connection, Medicine
Abstract: Implant rehabilitation is a daily practice in dentistry, and patients often have heightened expectations regarding both the functional and the aesthetic outcome. Implant–abutment connection (IAC) is involved in the long-term aesthetic quality of the rehabilitation. The use of one-piece implants for fixing dentures may prevent the mechanical and biological implication of the implant–abutment interface, resulting in a better quality of hard and soft tissue maintenance. In this case report, we present a novel one-piece implant in a maxillary rehabilitation with a full model-free digital approach.

Abstract: BACKGROUND The coronavirus disease 2019 (COVID-19) pandemic has adversely affected diagnosis and treatment of noncommunicable diseases. Its effects on delivery of diagnostic care for cardiovascular disease, which remains the leading cause of death worldwide, have not been quantified. OBJECTIVES The study sought to assess COVID-19`s impact on global cardiovascular diagnostic procedural volumes and safety practices. METHODS The International Atomic Energy Agency conducted a worldwide survey assessing alterations in cardiovascular procedure volumes and safety practices resulting from COVID-19. Noninvasive and invasive cardiac testing volumes were obtained from participating sites for March and April 2020 and compared with those from March 2019. Availability of personal protective equipment and pandemic-related testing practice changes were ascertained. RESULTS Surveys were submitted from 909 inpatient and outpatient centers performing cardiac diagnostic procedures, in 108 countries. Procedure volumes decreased 42% from March 2019 to March 2020, and 64% from March 2019 to April 2020. Transthoradc echocardiography decreased by 59%, transesophageat echocardiography 76%, and stress tests 78%, which varied between stress modalities. Coronary angiography (invasive or computed tomography) decreased 55% (p < 0.001 for each procedure). hi multivariable regression, significantly greater reduction in procedures occurred for centers in countries with lower gross domestic product. Location in a low-income and lower-middle-income country was associated with an additional 22% reduction in cardiac procedures and less availability of personal protective equipment and teteheatth. CONCLUSIONS COVID-19 was associated with a significant and abrupt reduction in cardiovascular diagnostic testing across the globe, especially affecting the world's economically challenged. Further study of cardiovascular outcomes and COVID-19-related changes in care delivery is warranted. (C) 2021 The Authors.

Abstract: The aim of this article is to propose a simplified digital protocol for the treatment of the fully edentulous patient, using an immediate implant and immediate loading protocol to deliver a polymethyl methacrylate metal-reinforced hybrid prosthesis. Ten consecutive patients were treated with this approach. At the end of 1 year, there was an implant survival rate of 97.8% and a prosthetic success rate of 100%. Based on the responses to the quality of life questionnaire, patients had a high acceptance rate for this treatment protocol. Within the limits of this case series, the proposed simplified digital protocol could be utilized for reconstruction in the fully edentulous patient and for delivering an implant-supported prosthesis immediately after implant placement.

Abstract: Made available in DSpace on 2020-12-12T02:01:20Z (GMT). No. of bitstreams: 0 Previous issue date: 2020-01-01 Background/purpose: The existing literature lacks information regarding the use of digital workflows during pre-surgical planning of implant rehabilitations in resorbed edentulous ridges. Thus, the aim was to evaluate the effectiveness of computer-guided implant placement and simultaneous computer-aided guided bone regeneration (GBR) in the treatment of atrophic posterior alveolar ridges. Materials and methods: Partially edentulous patients requiring GBR simultaneously to implant insertion were enrolled. Implant positions and the augmented missing bone were planned with specific software. A stereolithographic model of the grafted jaw was produced to transfer the virtual bone augmentation to the surgical field. A tooth-supported stent was used to guide implant insertion according to the virtual project. Visual analogue scales (VASs) were used to self-register postoperative pain, swelling, bleeding, and perception of the operation. Post-operative cone-beam computed tomography scan was superimposed to the virtual project to evaluate the accuracy of implant positions. Results: Overall, 10 implants were placed in 5 patients. Healing proceeded uneventfully in all except one patient that showed a dehiscence of the lingual flap as early surgical complication. Nevertheless, complete filling of the bone defects was observed clinically and radiographically in all patients. Pain scored exceptionally high with respect to the other variables. Deviations of 0.73 ± 0.21 mm, 0.59 ± 0.28 mm, and 3.05° ± 1.22° were found at implant head, apex, and long-axis respectively. Distal implants showed higher angular deviations compared to mesial implants (p = 0.008). Conclusion: Computer-guided approach provided encouraging results in terms of efficacy and accuracy. Conversely, patient-centered outcomes were below the expectations.

Abstract: Made available in DSpace on 2022-04-29T08:37:18Z (GMT). No. of bitstreams: 0 Previous issue date: 2022-03-01 Background: Antimicrobial photodynamic therapy (aPDT) is used in endodontics to improve orthograde root canal disinfection as an adjunct to standard treatments. Conversely, evidence concerning the application of aPDT in retrograde endodontic surgery is limited. Thus, the aim of the present study was to provide additional data regarding the use of aPDT in the surgical endodontic treatment of periapical lesions. Methods: A total of 25 consecutive patients presenting teeth with periapical radiolucency eventually associated with clinical signs and symptoms of apical periodontitis were included. Following access flap completion, osteotomy, mechanical debridement, root apical third resection, and preparation of the root-end cavity, aPDT was applied to decontaminate the surgical site using phenothiazine chloride dye at a concentration of 10 mg/mL and irradiation with a hand-held 100-mW diode laser with a wavelength of 660 ± 10 nm. At the latest follow-up visit, healing was evaluated as successful, uncertain, or failure according to well-established clinical and radiological criteria. Results: Overall, 31 periapical lesions were treated with aPDT. Healing proceeded uneventfully. The mean follow-up time was 36.19 months, with times ranging from 12 to 85 months. A total of 25 (80.65%) cases were classified as successful, 5 (16.13%) as uncertain, and only one (3.22%) as failure. Irrespective of the treatment outcome, all treated teeth were still functional, with no symptoms reported by the patients. Conclusion: aPDT as an adjunctive treatment modality in the surgical endodontic treatment of periapical lesions showed promising medium-term results associated with preservation of all diseased teeth.

Abstract: The quality and quantity of peri-implant soft tissues at the crestal portion of dental implants are important aspects to consider for a long-term successful implant-supported rehabilitation. Some relevant factors attributed to the implant health include mucosal thickness and keratinization. In this respect, many techniques and materials have been described to augment and improve buccal peri-implant soft tissues. Over the last few years, newly developed xenogeneic collagen matrices have been introduced in peri-implant plastic surgery to replace autogenous soft tissue grafts; however, data remain controversial so far. Thus, the purpose of the present report was to present a novel surgical technique conceived to augment buccal peri-implant soft tissues in combination with a volume-stable porcine collagen matrix. The rationale and the fundamental concepts that led to the use of a xenogeneic matrix to increase soft tissue volumes were also discussed.

Abstract: Objectives: A wide variety of approaches have been proposed to manage anticoagulant drugs in patients undergoing dental surgery; vitamin K antagonists and novel direct oral anticoagulants have been used. The present study aims to explore the existing evidence concerning the management of patients in anticoagulant therapy undergoing oral surgery procedures and to give suggestions related to peri- and post-operative measures. Materials and methods: A comprehensive search of databases was conducted to identify studies that evaluated the relationship between direct oral anticoagulants and dental procedures. The present scoping review was realized in adherence with the Preferred Reporting Items for Systematic reviews and Meta-Analyses extension for Scoping Reviews (PRISMA-ScR) guidelines. The publications varied from randomized controlled trials (RCT) to cohort trials. Only articles written in English language and published between 2000 to 2020 were screened. The studies were included if discussing the management of a patient in anticoagulant therapy (warfarin or direct oral anticoagulants) scheduled for tooth extraction. Results: 33 studies were selected and included in the qualitative review. Nineteen considered anticoagulant therapy with warfarin, six considered anticoagulant therapy with new oral anticoagulants and eight compared patients taking warfarin with patients taking direct oral anticoagulants. Conclusions: No case of extractive surgery should alter the posology of the drug: thromboembolic risks derived from discontinuation are heavier than hemorrhagic risks. Clinical relevance: direct oral anticoagulants are safer in terms of bleeding and manageability and bleeding episodes are manageable with local hemostatic measures.

Abstract: Purpose The aim of this long-term retrospective study was twofold: (1) to evaluate the survival and success rates of stepped screw titanium implants with a sandblasted and acid-etched surface, and (2) to assess the influence of hypothetical predictors of implant failure on the survival rate. Materials and methods From 75 possible candidates, 67 patients contributing 346 Frialit-2 (DPS Frialit-2 implant system, Friatech) implants placed between 1997 and 2005 were retrospectively evaluated. The inclusion criteria consisted of implants placed in either native or augmented bone, rehabilitated with an implant-supported prosthesis, and radiographically documented at the time of prosthetic loading (T0). At the follow-up recall performed between January and October 2018 (T1), clinical and radiologic examinations were conducted to evaluate the survival and success rates. The influence of specific variables on the survival rate was subsequently investigated, including gender and smoking habits, location and size of the implants, and bone augmentation procedures. Cox regression and shared frailty models were used, with the patient representing the statistical unit. Results A survival rate of 91.62% over a median observation time of 189 months with a range of 11 to 20 years was observed. A total of 14 out of 29 implants failed before delivery of the provisional prosthesis. Overall, the median marginal bone loss was 1.25 mm, with an annual increase of 0.12 mm. Different from the other variables, the results of the multivariate model indicated that smoking was strongly correlated with implant failure (P = .002). Conclusion Considering the limitations of this study, stepped screw titanium implants with a sandblasted and acid-etched surface provided a good survival rate. Smoking might be considered a relevant risk factor for implant failure.

Abstract: Purpose The timing for soft tissue augmentation during implant therapy is still debated. Therefore, the present study clinically evaluated whether immediate versus delayed soft tissue augmentation procedures had an impact on the stability of peri-implant mucosal thickness (PMT). Materials and Methods Patients requiring a single implant posterior to the canines in association with soft tissue augmentation procedures at the buccal aspect of single implants using a connective tissue graft (CTG) were enrolled. Patients were randomly allocated to 2 different timing protocols: simultaneous implant and CTG placement (test group) or implant placement and then CTG placement after 3 months (control group). PMT was measured clinically at the mid-buccal aspect of the implant site by bone sounding with an endodontic K-file using customized acrylic stents. PMT measurements were recorded before and after implant placement and at 1, 2, 3, 4, 6, 9, and 12 months after implant insertion. Parametric statistical tests were used to compare PMT between the test and control groups at each study period and to evaluate changes in PMT over time. The level of significance was set at a P value less than .05. Results Fourteen implants placed in 14 patients were available for statistical comparison. At 12 months, the difference in PMT between the test and control groups was 0.12 ± 0.51 mm. This difference was not statistically significant (P = .54). A significant increase in PMT was observed from baseline to 12 months after implantation in the test (P = .004) and control (P Conclusions The present study indicated that changes in PMT after CTG placement were not influenced by the timing of soft tissue augmentation and remained stable up to 1 year after implant insertion.

Abstract: Purpose To evaluate the long-term outcome of dental implants placed with a staged procedure in resorbed alveolar ridges reconstructed with iliac crest autogenous onlay grafts. Materials and methods All consecutive patients treated with iliac crest onlay bone grafts and dental implants were retrospectively evaluated. During the appointment, clinical and radiological examinations were conducted to assess implant survival. A survived implant was defined as an implant still stable and in function at the follow-up visit. Implant survival was estimated at the implant level using Kaplan-Meier analyses. The cumulative survival rate was estimated using a life-table analysis. Subgroup analyses were performed for age, position, and type of retention using the log-rank test. A p-value of Results The cohort consisted of 21 female subjects receiving a total of 140 rough-surface titanium implants. Of them, 128 survived and 12 failed, yielding a cumulative survival rate of 91.1% over a median survival time of 312 months. Implants supporting cement-retained prostheses exhibithed lower survival rate compared to screw-retained restorations (p = 0.001). Conclusion Implants placed in bone augmented with iliac crest onlay grafts showed high long-term survival rates. Cement-retained restorations were more prone to develop implant failures.

Abstract: Background: In early 2020, COVID-19 massively hit Italy, earlier and harder than any other European country. This caused a series of strict containment measures, aimed at blocking the spread of the pandemic. Healthcare delivery was also affected when resources were diverted towards care of COVID-19 patients, including intensive care wards. Aim of the study: The aim is assessing the impact of COVID-19 on cardiac imaging in Italy, compare to the Rest of Europe (RoE) and the World (RoW). Methods: A global survey was conducted in May–June 2020 worldwide, through a questionnaire distributed online. The survey covered three periods: March and April 2020, and March 2019. Data from 52 Italian centres, a subset of the 909 participating centres from 108 countries, were analyzed. Results: In Italy, volumes decreased by 67% in March 2020, compared to March 2019, as opposed to a significantly lower decrease (p < 0.001) in RoE and RoW (41% and 40%, respectively). A further decrease from March 2020 to April 2020 summed up to 76% for the North, 77% for the Centre and 86% for the South. When compared to the RoE and RoW, this further decrease from March 2020 to April 2020 in Italy was significantly less (p = 0.005), most likely reflecting the earlier effects of the containment measures in Italy, taken earlier than anywhere else in the West. Conclusions: The COVID-19 pandemic massively hit Italy and caused a disruption of healthcare services, including cardiac imaging studies. This raises concern about the medium- and long-term consequences for the high number of patients who were denied timely diagnoses and the subsequent lifesaving therapies and procedures.

Abstract: In order to improve the clinical outcome of patients with cardiovascular disease, appropriate therapeutic options should be selected including medical treatment and coronary intervention. Current available data indicates that revascularization should be the treatment of choice in patients with moderate-to-severe inducible ischemia and/or abnormal myocardial blood flow in the matching territory, measured by radionuclide techniques. Conversely, invasive procedures – and associated costs and morbidity – can be safely avoided in patients with no significant ischemic burden. Refined targeting of the areas to be revascularized using quantitative blood flow measurements with PET may further improve the outcome of patients submitted for intervention. Following revascularization, perfusion studies provide crucial diagnostic and prognostic information, and their use is appropriate during follow-up in those individuals with recurrent symptoms. However, routine imaging in asymptomatic patients is still controversial and mostly reserved for high-risk populations, despite an increasing trend for testing all patients during long-term follow-up after intervention.

Abstract: Aim: The present study evaluated the clinical and radiological stability of hard and soft tissues following alveolar socket preservation (ASP) procedure with a follow-up of 5year from implant insertion. Materials and methods: The initial sample consisted of seven patients who underwent single tooth extraction and ASP procedure by means of demineralized bovine bone mineral particles covered with a porcine-derived non-cross-linked collagen matrix (CM). Each patient received a submerged single implant in the healed site. Mesial and distal peri-implant marginal bone resorption (MBR) rates were assessed radiographically at 1year (T1) and 5years (T2) after implant placement (baseline value). Results and Statistics: No dropouts occurred up to 5years. At T1, the MBR was 0.08 ± 0.16mm at the mesial aspect and 0.1 ± 0.12mm at the distal aspect. This difference was not statistically significant (P = 0.867). At T2, the mesial MBR was 0.15 ± 0.17mm and the distal MBR was 0.11 ± 0.14mm, with a non-statistically significant difference (P = 0.532). Therefore, no statistically significant differences were detected comparing mesial and distal MBR at any time point. With respect to the intra-group comparisons, no differences were observed comparing the different study periods within each variable. Indeed, the comparison between T0, T1 and T2 was non-statistically significant at both mesial (P = 0.06) and distal (P = 0.06) aspects. After 5years, the volume of the soft tissues appeared clinically well maintained with a natural aspect around dental implants and adjacent teeth. Conclusion: ASP using demineralized bovine bone mineral in combination with CM proved to be an effective technique to maintain stable dimensional volumes of both hard and soft tissues.

Abstract: Background: The coronavirus disease-2019 (COVID-19) pandemic significantly affected management of cardiovascular disease around the world. The effect of the pandemic on volume of cardiovascular diagnostic procedures is not known. Objectives: This study sought to evaluate the effects of the early phase of the COVID-19 pandemic on cardiovascular diagnostic procedures and safety practices in Asia. Methods: The International Atomic Energy Agency conducted a worldwide survey to assess changes in cardiovascular procedure volume and safety practices caused by COVID-19. Testing volumes were reported for March 2020 and April 2020 and were compared to those from March 2019. Data from 180 centers across 33 Asian countries were grouped into 4 subregions for comparison. Results: Procedure volumes decreased by 47% from March 2019 to March 2020, showing recovery from March 2020 to April 2020 in Eastern Asia, particularly in China. The majority of centers cancelled outpatient activities and increased time per study. Practice changes included implementing physical distancing and restricting visitors. Although COVID testing was not commonly performed, it was conducted in one-third of facilities in Eastern Asia. The most severe reductions in procedure volumes were observed in lower-income countries, where volumes decreased 81% from March 2019 to April 2020. Conclusions: The COVID-19 pandemic in Asia caused significant reductions in cardiovascular diagnostic procedures, particularly in low-income countries. Further studies on effects of COVID-19 on cardiovascular outcomes and changes in care delivery are warranted.

Abstract: Background: bone augmentation by means of manually shaped titanium mesh is an established procedure to regenerate atrophic alveolar ridges and recreate a proper contour of the peri-implant bone anatomy. Conversely, current literature on the use of preformed titanium meshes instead of traditional grids remains lacking. Therefore, the aim of the present prospective study was to evaluate the use of preformed titanium mesh to support bone regeneration simultaneously to implant placement at dehiscence-type defects from clinical, radiological, and patient-related outcomes. Methods: 8 implants showing buccal dehiscence defects were treated with preformed titanium mesh directly fixed to flat abutments screwed to the implant. Intrasurgical clinical measurements and radiographic evaluations by means of cone-beam computed tomography scans were performed to assess the horizontal bone gain after 8 months from the augmentation surgery. Biological and patient-centered outcomes were also evaluated., Results: clinically, a mean horizontal bone gain of 4.95 &plusmn, 0.96 mm, and a mean horizontal thickness of the buccal plate of 3.25 &plusmn, 0.46 mm were found. A mean horizontal bone gain of 5.06 &plusmn, 0.88 mm associated with a mean horizontal thickness of the buccal plate of 3.45 &plusmn, 0.68 mm were observed radiographically. From a macroscopic aspect, the remodeled graft appeared well integrated with the host bone. Well vascularized newly formed bone-like tissue was observed in intimate contact with the implants. Conclusions: preformed titanium mesh may be effective in supporting simultaneous horizontal bone regeneration at dehiscence-type peri-implant defects. Titanium mesh exposure still remain an issue in this type of surgery.

Abstract: The aim of the present case report was to show the 17-year hard and soft tissues stability of guided bone regeneration procedure associated with dental implants insertion. A 52-year-old male patient presented with a partial edentulism in the upper right maxilla. A graft consisting of deproteinized bovine bone mineral and autogenous bone stabilized by a non-resorbable expanded polytetrafluoroethylene membrane was used to reconstruct the missing bone applying the biological principles of guided bone regeneration. Dental implants were inserted simultaneously in a prosthetically driven position. Soft tissues were managed with a coronally positioned palatal sliding flap technique to obtain a primary intention healing. The healing proceeded uneventfully, and after 8 months the re-entry procedure was carried out. The defect was three-dimensionally filled by newly formed bone in an ongoing maturation phase. The regenerated bone appeared strictly integrated within the surrounding hard tissue and well vascularized....

Abstract: Insufficient crown height space, particularly in the interforaminal region of edentulous ridges with knife-edge morphology, may prevent successful prosthetic rehabilitation. Such conditions require osteoplasty, which might complicate computer-guided implant placement. This clinical report illustrates the treatment of a patient with complete edentulism rehabilitated with a mandibular implant-supported fixed dental prosthesis by using a virtually guided approach. Both alveolar ridge reduction and prosthetically driven implant insertions were computer-guided by surgical stents to increase accuracy and predictability. This approach enabled the immediate loading of the implants with an interim prosthesis before the delivery of a definitive screw-retained fixed prosthesis. At the 1-year follow-up visit, clinical and radiographic examination revealed a stable outcome.

Abstract: Introduction: An optimal aesthetic implant restoration is a combination of a visually pleasing prosthesis and adequate surrounding peri-implant soft tissue architecture. This study describes a novel workflow for one-step formation of the supra-implant emergence profile. Materials and Methods: Two randomized groups were selected. Ten control group participants received standard healing screws at the surgical stage. Ten individualized healing abutments were Computer aided Design/Computer aided Manufacturing (CAD/CAM)-fabricated out of polyether ether ketone (PEEK) restoration material in a fully digital workflow and seated at the surgical stage in the test group. The modified healing abutment shape was extracted from a virtual library. The standard triangulation language (STL) files of a premolar and a molar were obtained considering the coronal anatomy up to the cement-enamel junction (CEJ). After a healing period ranging from 1 to 3 months depending on the location of the surgical site, namely, mandible or maxilla, a digital impression was taken. The functional implant prosthodontics score (FIPS) and the numerical rating scale (NRS) of pain were recorded and compared. Results: The mean FIPS value for the test group was 9.1 &plusmn, 0.9 while the control group mean value was 7.1 &plusmn, 0.9. In the test group, pain assessment at crown placement presented a mean value of 0.5 &plusmn, 0.7. On the contrary, the control group showed a mean value of 5.5 &plusmn, 1.6. Conclusions: Patients in the test group showed higher FIPS values and lower NRS scores during the early phases compared to the control group.

Abstract: Background: The presence of keratinized tissue around dental implants is more than desirable either from a functional and aesthetic point of view, making soft tissue grafting a common practice in implant rehabilitation. Autogenous soft tissue grafting procedures are usually associated with high morbidity. Aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants. Methods: 15 consecutive patients underwent a vestibuloplasty and grafting, both in the mandible and the maxilla, with a collagen matrix. Results: The primary endpoint was to evaluate the resorption of the graft along with the re-epithelization grafted area. The percentage of the resorption was 44,4%, with a mean gain in vestibular height of 3 mm. Secondary endpoints evaluated the clinical appearance, the hemostatic effect and the post-operative pain. All subjects referred minimal pain with no bleeding. No adverse reaction nor infection were noted. Conclusion: This study showed that the used collagen matrix can find major interest in those patients who need a greater aesthetic outcome as the matrix has a perfect integration with the surrounding tissues. Furthermore it is strongly recommended for those patients who can bear little pain. Clinical Significance: Post-operative morbidity of autologous grafts is the biggest concern of this type of surgery. The possibility to use a soft tissue substitute is a great achievement as morbidity decreases and bigger areas can be treated in a single surgery. The present study showed the efficacy of a collagen matrix as this kind of substitute.

Abstract: Background When keratinized tissue width around dental implants is poorly represented, the clinician could resort to autogenous soft tissue grafting. Autogenous soft tissue grafting procedures are usually associated with a certain degree of morbidity. Collagen matrices could be used as an alternative to reduce morbidity and intra-operatory times. The aim of this study was to assess the efficacy of a xenogeneic collagen matrix as a substitute for soft tissue grafting around dental implants. Methods Fifteen consecutive patients underwent a vestibuloplasty and keratinized tissue reconstruction around dental implants, both in the mandible and the maxilla, with a porcine collagen matrix. The so obtained keratinized tissues were measured and evaluated after 6 months and 1, 4, and 5 years. Results The average gain of keratinized tissue was 5.7 mm. After 6 months, it was observed a resorption of 37%, after 1 year 48%, and after 5 years 59%. The mean gain of keratinized tissue after 5 years was 2.4 mm. Hemostatic effect and post-operative pain were evaluated too. All subjects referred minimal pain with no bleeding. No adverse reaction nor infection was noted. Conclusions The present study showed the efficacy of a porcine collagen matrix in keratinized tissue augmentation. The possibility to use a soft tissue substitute is a great achievement as morbidity decreases and bigger areas can be treated in a single surgery.

Abstract: An adequate amount of bone all around the implant surface is essential in order to obtain long-term success of implant restoration. Several techniques have been described to augment alveolar bone volume in critical clinical situations, including guided bone regeneration, based on the use of barrier membranes to prevent ingrowth of the epithelial and gingival connective tissue cells. To achieve this goal, the use of barriers made of titanium micromesh has been advocated.A total of 13 patients were selected for alveolar ridge reconstruction treatment prior to implant placement. Each patient underwent a tridimensional bone augmentation by means of a Ti-mesh filled with intraoral autogenous bone mixed with deproteinized anorganic bovine bone in a 1:1 ratio. Implants were placed after a healing period of 6 months. Panoramic x-rays were performed after each surgical procedure and during the follow-up recalls. Software was used to measure the mesial and the distal peri-implant bone loss around each implant. The mean peri-implant bone loss was 1.743 mm on the mesial side and 1.913 mm on the distal side, from the top of the implant head to the first visible bone-implant contact, at a mean follow-up of 88 months.The use of Ti-mesh allows the regeneration of sufficient bone volume for ideal implant placement. The clinical advantages related to this technique include the possibility of correcting severe vertical atrophies associated with considerable reductions in width and the lack of major complications if soft-tissue dehiscence and mesh exposures do occur.

Abstract: Alveolar bone regeneration by means of titanium meshes is a widespread procedure, however to date, only few relevant studies were reported in literature concerning this technique. Consequently, the aim of the present systematic review was to analyze the reliability of the titanium mesh as a barrier, in conjunction with horizontal and vertical ridge reconstruction for implant placement purposes. A total of 17 articles complying with the inclusion and exclusion criteria were reviewed. Three outcome variables were defined: a) horizontal and vertical bone regeneration obtained, b) complication rate, defined as the percentage of membrane exposures and c) evaluation of implant survival, success and failure rate.In regards to the vertical regeneration the mean was 4.91 mm (range: 2.56 - 8.6), while a mean of 4.36 mm (range: 3.75 - 5.65) was calculated for horizontal reconstruction. Considering the exposure rate, a mean of 16.1% was found, nevertheless, implant placement were placed in almost all of the sites. A mean success rate of 89,9%, a mean survival rate of 100% and a failure rate of 0% emerged from the data evaluation. A meta-analysis could not be performed due to the heterogeneity of the data, however the final results were comparable with those reported in case of bone regeneration obtained through other types of non-resorbable membranes. An advantage in favour of the titanium mesh was found in terms of bone loss after exposure, as implant placement was not jeopardized in almost all of the cases. It could be deduced that titanium meshes represented a reliable solution for alveolar ridge reconstruction. The clinical studies currently available in literature have shown the predictability of this technique in both lateral and vertical bone regeneration.

Abstract: Ectodermal dysplasia (ED) is an inherited disorder characterized by abnormality of ectodermally derived structures. A recurrent oral finding is oligodontia, which in turn leads to a severely hypotrophic alveolar process with typical knife-edge morphology and adverse ridge contours. This unfavorable anatomy can seriously hamper proper implant placement. Fresh-frozen bone (FFB) allografts recently have been proposed to augment the residual bone volume for implant placement purposes; however, scientific evidence concerning the use of FFB to treat ED patients is absent. Similarly, data reporting computer-aided template-guided implant placement in medically compromised patients are limited. Thus the purpose of this report is to illustrate the oral rehabilitation of a female patient affected by ED and treated with appositional FFB block grafts and consecutive computer-guided flapless implant placement in a 2-stage procedure. Fixed implant-supported dental prostheses were finally delivered to the patient, which improved her self-esteem and quality of life. During the follow-up recall 1 year after the prosthetic loading, the clinical examination showed healthy peri-implant soft tissues with no signs of bleeding on probing or pathologic probing depths. The panoramic radiograph confirmed the clinical stability of the result. Peri-implant marginal bone levels were radiographically stable with neither pathologic bone loss at the mesial and distal aspects of each implant nor peri-implant radiolucency. Within the limitations of this report, the use of FFB allografts in association with computer-aided flapless implant surgery might be considered a useful technique in patients affected by ED.

Abstract: Maxillary sinus floor elevation via a lateral approach is a predictable technique to increase bone volume of the edentulous posterior maxilla and consequently for dental implants placement. The sinus floor is elevated and it can be augmented with either autologous or xenogeneic bone grafts following an opening bone window created on the facial buccal wall. Maxillary septa are walls of cortical bone within the maxillary sinus. The septa shape has been described as an inverted gothic arch arising from the inferior or lateral walls of the sinus and may even divide the sinus into two or more cavities. Some authors have reported a higher prevalence of septa in atrophic edentulous areas than in nonatrophic ones. Radiographic identification of these structures is important in order to perform the right design of the lateral window during sinus lift. Aim of this investigation is to highlight the correct steps for doing sinus lift surgery in presence of those anatomic variations. Clinicians should always perform clinical and radiographic diagnosis in order to avoid complications related to the sinus lift surgery.

Abstract: Physiologic resorption due to remodeling processes affects autogenous corticocancellous grafts in the treatment of atrophic jawbone alveolar ridges. Such a situation in the past made overgrafting of the recipient site mandatory to get enough bone support to dental implants in order to perform a prosthetic rehabilitation. Anorganic bovine bone, conventionally used to treat alveolar bone deficiencies in implant surgery, showed a high osteoconductive property thanks to its micro and macrostructure very similar to that of human hydroxyapatite. An original technique provides for the application of a thin layer of anorganic bovine bone granules and a collagen membrane on the top of the corticocancellous onlay bone grafts to reduce in a remarkable way the graft resorption due to remodeling. The results of a clinical prospective study and a histomorphometric analysis done on autogenous grafts harvested from the iliac crest showed that the proposed technique is able to maintain the original bone volume of the corticocancellous blocks.

Abstract: The reconstruction of the atrophic alveolar ridges for implant placement is today a common procedure in dentistry daily practice. The surgical reconstruction provides for the optimization of the supporting bone for the implants and a restoration of the amount of keratinized gingiva for esthetic and functional reasons. In the past, tissue regeneration has been performed with autogenous bone and free gingival or connective tissue grafts. Nowadays, bone substitutes and specific collagen matrix allow for a complete restoration of the atrophic ridge without invasive harvesting procedures. A maxillary reconstruction of an atrophic ridge by means of tissue substitutes and its histological features are then presented.

Abstract: Purpose The purpose of this study was to evaluate the effect of submucosal administration of dexamethasone sodium phosphate on discomfort after mandibular third molar surgery. Patients and Methods Sixty-one consecutive patients requiring surgical removal of a single mandibular impacted third molar under local anesthesia were randomly placed into 3 groups. After the onset of local anesthesia, the experimental groups received dexamethasone at 2 different doses (4 or 8 mg) as submucosal injection, and the control group received no drug. Standardized surgical and analgesic protocols were followed. Maximum interincisal distance and facial contours were measured at baseline and at postsurgery days 2 and 7. Pain was objectively measured by counting the number of analgesic tablets required. The patients’ perception of the severity of symptoms was assessed with a follow-up questionnaire (PoSSe scale). Results On the second postoperative day, facial edema showed a statistically significant reduction in both dexamethasone 4-mg and dexamethasone 8-mg groups compared with the control group, but no statistically significant differences were observed between the 2 dosage regimens of dexamethasone. By contrast, there was no statistically significant difference between all groups when postoperative swelling was evaluated at day 7 (P > .50). The treatment group had a limited and nonsignificant effect on pain and trismus when compared with the control group at the 2 times of evaluation. Conclusions Parenteral use of dexamethasone 4 mg, given as an intraoral injection at the time of surgery, is effective in the prevention of postoperative edema. Increasing the dose to 8 mg provides no further benefit.

Abstract: The purpose of the present study was to assess the cumulative survival rate (CSR) of 192 implants placed in association with guided bone regeneration (GBR) procedures to evaluate the long-term predictability of this technique. Moreover, the Kaplan Meier survival analysis was applied to the data in order to evaluate predictors of implant failures, including the source of the graft, the type of membrane, and the timing of implant placement. The CSR of the sample was 95.6% over a mean follow-up period of 78 months (range, 1–175 months). Considering the source of graft, a 95.0%, 93.3%, and 97.7% CSR was obtained for demineralized bovine bone mineral (DBBM), autologous, and 1:1 ratio mixture of autologous and DBBM grafts,, respectively. The CSR referred to bioabsorbable membranes was 96.5%, whereas 94.6% was the CSR reported for nonresorbable membranes. The CSR of simultaneous surgeries was 96.8%, whereas staged surgeries showed a CSR of 94.5%. According to the data, implants placed in conjunction with GBR procedures presented a satisfying survival rate even in the long term. All the procedures performed with different bone grafts and type of membranes guaranteed optimal results both in one- and two-stage approaches. No statistically significant differences could be detected among the groups; indeed, the use of DBBM associated with resorbable membranes may be suggested to reduce patients' morbidity and treatment time. Therefore, the dental implants placed in association with bone regenerative procedures presented safe and predictable long-term clinical results.

Abstract: Objectives The aim of the present long-term study was to retrospectively evaluate the survival rate of implants placed in regenerated maxillary sinuses and to assess the influence of hypothetical predictors of implant failure. Methods A database including 218 patients who received dental implants after sinus lift procedures was analyzed. The following variables were systematically included and evaluated: type of graft material used, number of surgeries performed, and use of membranes to cover the lateral antrostomy and/or to repair accidental Schneiderian membrane perforations. The Kaplan–Meier estimator was used for comparisons among the groups. Results A total of 589 dental implants were positioned in 246 grafted sinuses and were in function for 3–186 months. The Kaplan–Meier cumulative survival rate was 98.3% after 15.5 years of follow-up. All implant losses occurred within 52 months (4.3 years) after augmentation. According to the log-rank test, no statistically significant difference was shown between each patient/implant variable (p > 0.05). Conclusions Despite the limitations inherent in this type of study, no statistically significant differences between the groups could be found. Intraoperative Schneiderian membrane perforations did not affect the outcome of the implants positioned. Clinical significance The present long-term study is intended as a reference for clinicians approaching sinus floor elevation surgery in order to provide them with relevant operative findings. Since all the drawbacks occurred within the first 5 years, medium-term follow-up studies could be suitable for further retrospective evaluations.

Abstract: Purpose: Aim of the present study was to present the results of a retrospective analysis of maxillary sinus augmentation procedures performed with platelet-rich plasma (PRP) with a mean follow-up of about 5 years. The analysis was focused on implant survival rates and on the dimensional stability of the subantral cavity filling. Materials and Methods: Between 2000 and 2006, 28 patients were recruited for a maxillary sinus augmentation procedure performed with PRP. Two patients did not answer to the calling for the examination at distance, so they were excluded from the sample. The study involved 26 patients, for a total amount of 33 sinus augmentations, with an average follow-up of 65 months. In 26 procedures the grafting material used was a mixture of autologous bone taken from the oral cavity, deproteinized bovine bone Bio-Oss® in a relationship of 1:3 and PRP, while in seven cases, the combination of Bio-Oss and PRP. The dimensional stability of grafting material was investigated through X-ray measurements carried out during X-ray postexaminations. Results: After a mean follow-up time of about 5 years, the implant survival rate registered was 95.9%, while the radiographical variables used to assess the dimensional stability of grafts, showed a mean decrease respectively of 9.38% and 14.61%. Discussion: Very good long-term results were achieved using autologous bone+Bio-Oss+PRP and Bio-Oss+PRP as filling materials in the maxillary sinus augmentation. Dimensional stability of cavity filling seems to represent a very important factor for implant procedures success. It is difficult to estimate the influence of PRP on a long-term basis. Conclusion: The implant survival rate obtained in this study was similar to the expected rate on the areas not subject to bone graft. The method applied showed to be reliable for bone regeneration in subantral cavities, showing a very good dimensional stability and a slight reabsorption over the years.

Abstract: In the reoxygenated hypoxic heart, hypoxanthine is either oxidized by xanthine oxidase with production of toxic oxygen species or salvaged for the ATP pool by hypoxanthine-guanine phosphoribosyl transferase. To characterize the repartition of hypoxanthine between the two pathways, we have subjected rat hearts to 20 min hypoxia and monitored the recovery (ventricular, end-diastolic and coronary pressures, and the contraction rate) during the reoxygenation (30 min) in the presence of either hypoxanthine or guanine alone, or both. The rate-pressure product recovered 78% of the pre-hypoxia values in hearts reoxygenated with 100 microM hypoxanthine and 80% in hearts reoxygenated with 100 microM guanine, in contrast to 49% in the presence of both hypoxanthine and guanine (100 microM each). Thus, it is likely that hypoxanthine is salvaged when present alone and is oxidized generating the reperfusion injury when the salvage is prevented by guanine that competes with hypoxanthine from the same site of hypoxanthine-guanine phosphoribosyl transferase. The functional impairment was slower when hypoxanthine was replaced by xanthine, and was eliminated by superoxide dismutase and catalase, indicating that the injury is caused by toxic oxygen species generated from hypoxanthine and xanthine oxidase. These data suggest that the salvage pathway may be critical in preventing the reperfusion injury in hypoxic hearts.

Abstract: Hypoxanthine is the final product of the catabolism of ATP in the stored red cell. Upon transfusion, this purine may be uptaken by the endothelial cell and oxidized in a post-ischemic or post-anoxic environment with production of oxygen-derived free radicals. We have tested this hypothesis with a isolated perfused rat heart model monitoring the recovery of the heart function from 20 min anoxia in the presence of 0.1 mM hypoxanthine or xanthine. Addition of 0.1 mM guanine minimized the fraction of hypoxanthine to be salvaged. The presence of hypoxanthine in the vascular space impaired the recovery of the end-diastolic pressure, left ventricular developed pressure, contraction rate, and coronary perfusion pressure. We conclude that intravascular hypoxanthine is oxidized by the endothelial cell xanthine oxidase contributing to the post-anoxic reoxygenation injury. Since the injury led by equimolar xanthine was nearly half of that observed for hypoxanthine, this injury appears to be correlated to the stoichiometry of the oxygen-derived free radical generating reaction.

Abstract: DDMP, a diaminopyrimidine folate antagonist, was given to 26 tumor patients in a dosage of 50 mg/m2 per week orally, simultaneously with 3 mg CF i.m. or i.v. The CF dose was increased to 30 mg in patients showing evidence of toxicity, and withdrawn in the absence of toxicity. The dose-limiting toxicity was seen in myelosuppression, particularly thrombopenia and skin rashes. At the 3 mg CF level, 18 out of 26 patients developed toxicity. No toxicity was seen at the 30 mg CF level in 11 patients. After cessation of CF, toxicity occurred in five out of seven patients. After the onset of toxicity, CF was added as a delayed rescue, in a dosage of 15 mg every 8 h or 30–60 mg daily. One patient died of sepsis with agranulocytosis. All other patients recovered from myelosuppression within 1 or 2 weeks. Objective responses were observed in seven patients, four of the ten with epidermoid cancer of the head and neck, two out of eight with epidermoid cancer of the lung, and one out of three with melanoma.

Abstract: Aim: To report the clinical case of a child with facial and periorbital emphysema caused by an orthodontic device. Case report: An 11-year-old child presented to our clinic showing moderate swelling of the left facial area. Based on his dental history, physical findings, and instrument examinations, the diagnosis of cervicofacial emphysema was established, caused by disengagement of the facebow. One week later, all swelling and crepitus had disappeared without complications. Most patients who develop subcutaneous emphysema after a dental procedure have only moderate local swelling, which normally resolves spontaneously and without complications within a week. However, the spread of large amounts of air into the deeper spaces may cause life-threatening sequelae. Conclusions: Orthodontists should be aware that the use of extraoral traction applied via a facebow can cause soft tissue injures and emphysema of the cervicofacial region. It is important to avoid misdiagnosis and to appropriately inform patient and parents about this condition.
