Background: Connective tissue graft substitutes have been used widely to overcome autogenous graft limitations. Nevertheless, they do not provide comparable results in the treatment of periodontal and peri‐implant soft tissue defects. Based on the principles of tissue‐engineered materials, injectable platelet‐rich fibrin (i‐PRF) has been combined with collagen matrices (CMs) to enhance their clinical efficacy. To the best of our knowledge, this is the first case series demonstrating the use of i‐PRF for the biofunctionalization of a volume‐stable collagen matrix (VCMX) as an adjunct to coronally advanced flap (CAF) to treat single gingival recession (GR) defects. Methods & Results: The study included 10 patients. Bleeding on probing, probing depth, GR height, clinical attachment level, esthetics, and dentin hypersensitivity were evaluated. After 6 months, a significant GR reduction (RecRed: 2.15 ± 0.7 mm; p = 0.005) and percentage of root coverage (% RC) of 81.13% were observed. Additionally, 40% of the sites showed complete root coverage. Gingival thickness increased 0.64 mm. Patient‐centered evaluations demonstrated dentin hypersensitivity and esthetics improvements by the end of follow‐up. Conclusion: VCMX biofunctionalized with i‐PRF associated with CAF technique showed promising clinical outcomes in the treatment of single RT1 GR defects. [ABSTRACT FROM AUTHOR]

Introduction: Collagen matrices have been used as connective tissue graft (CTG) substitutes. However, they do not have the same efficacy compared to CTG. Adding biological agents may increase collagen matrices' efficacy. The present case reports the use of a biofunctionalized volume‐stable collagen matrix (VCMX) with injectable platelet‐rich fibrin (iPRF) associated with the coronally advanced flap (CAF) to treat single gingival recession (GR) defect. Case Presentation: A Recession Type 1 (RT1 A‐) defect at maxillary left canine in a male patient was treated using a VCMX biofunctionalized with iPRF associated with CAF. No swelling or edema was observed during the first 14 days after surgery. Complete root coverage was observed (RecRed of 4.0 mm) after 6 months. Gingival thickness (GT) increased (1.0 mm) by the end of the follow‐up. Conclusion: The present case report shows that CAF associated with VCMX+iPRF presents good clinical outcomes for single GR defect. Key points: Why is this case new information?This case is the first one to our knowledge to describe the biofunctionalization of VCMX with iPRF to treat single gingival recession. What are the keys to successful management of this case?Proper material handling.Proper iPRF protocol execution. What are the primary limitations to success in this case?Need of venipuncture.Correct preparation of VCMX+iPRF.Patient compliance. [ABSTRACT FROM AUTHOR]

Introduction: Gingival recession (GR) is a relevant clinical condition due to its high prevalence worldwide, which leads to aesthetic demands and dentin hypersensitivity. Collagen matrices have been associated with different designs of coronally advanced flaps (CAFs) to treat GR defects. However, the literature lacks long‐term follow‐up of this treatment option. The aim of this study is to present the long‐term follow‐up (up to 7 years) of two GR defects (associated or not with noncarious cervical lesion) treated with a CAF and a collagen matrix (CM). Case presentation: Case 1 underwent a CAF associated with a CM to treat a single GR defect. After 7 years, Case 1 presented with 3 mm of recession reduction, which corresponds with the 85.7% of root coverage. Case 2 presented two GR defects associated with noncarious cervical lesions (NCCLs). The NCCLs were partially restored with resin composite and then underwent a modified CAF for multiple defects and a CM. After 5 years of follow‐up, Case 2 presented with 1.5 and 2.5 mm of recession reduction, which corresponds with the average 83.3% defect coverage. Conclusion: These two cases may show that CMs can provide long‐term stable outcomes in the treatment of GR defects. Why is this case new information?One of the cases is the first one to describe a 7 years of follow‐up after CAF+CM to treat gingival recession defects. What are the keys to successful management of this case?Correct material handling.Adequate restorative protocol and surgical technique. What are the primary limitations to success in this case?DiagnosePatient compliance. [ABSTRACT FROM AUTHOR]

Background Methods and Results Conclusion Highlights The inherently technique‐sensitive nature of periodontal plastic procedures demands a significant level of skill and expertise. The incorporation of three‐dimensional (3D) printing technologies emerges as a potential strategy to optimize and simplify surgical procedures. This case report describes the digital workflow and presents the clinical outcomes achieved using a guided coronally advanced flap for the treatment of a single gingival recession (GR).A female patient with a gingival recession type 1 (RT1 B‐) defect on the mandibular second left premolar underwent successful treatment using a guided coronally advanced flap (g‐CAF) and de‐epithelized connective tissue graft (CTG). The digital planning included intraoral scanning of the mandible and hard palate using an intraoral scanner, with resulting polygon format (PLY) files exported for virtual model creation. The CAF guide was meticulously designed to orient horizontal and vertical incisions at the papillae base adjacent to the GR defect. For the donor site, a guide was specifically created, positioning the graft area 2 mm apically to the premolars' gingival margins. The delineation of this area involved two horizontal and vertical incisions, meticulously based on the dimensions of the GR. The digitally designed guides were then 3D‐printed using a surgical guide‐specific resin, contributing to the precise execution of the innovative surgical approach. Complete root coverage was achieved.This case report demonstrates that g‐CAF can be a promising approach for the treatment of single GR.Why is this case new information? To the best of the authors' knowledge, this is the first manuscript to report a guided procedure for the treatment of gingival recession. This report provides the digital workflow for the fabrication of a guide to perform the coronally advanced flap for single recession defects. What are the keys to successfully manage this case? It is necessary to adequately scan the recession defect area and palate. Properly not only design the guide using specific software but also print it. The guide has to be stable when in position for the surgical procedure. What are the primary limitations of this technique? This guide was designed to help surgeons during the incisions. However, it does not provide aid to split and release the flap and suture. [ABSTRACT FROM AUTHOR]

Collagen matrixes have been developed as possible connective tissue graft substitutes to overcome patient discomfort, undesired palatal healing, and the limited amount of donor tissue. The aim of this case series is to assess a coronally advanced flap (CAF) with a new volume-stable collagen matrix (VCMX) to treat single gingival recession (GR) associated with partially restored non-carious cervical lesions (NCCL). Twelve patients diagnosed with single GR RT1 &#43; NCCL (B&#43;) were included in this study and received a restorative - partial resin composite with apical margin 1 mm beyond the estimated cementoenamel junction (CEJ) - and a surgical approach - CAF&#43;VCMX. Clinical and patient-centered assessments were recorded at baseline and 6 months postoperatively from ten patients. Significant recession reduction (RecRed:2.1mm), clinical attachment level gain (CAL:1.34mm), and combined defect coverage (CDC) of 51.67% were observed at 6 months. The estimate root coverage (RC) was 69.48%, obtained using the estimated CEJ. No difference in keratinized-tissue width (KTW) was observed over time. A gain in gingival thickness (GT) of 0.42 mm was observed after 6 months (p&#61;.002) and an improvement in patient satisfaction due to better esthetics (p<.001). Within the present study's limits, CAF plus VCMX provided significant improvement in treating single GR combined with partially restored NCCL (B&#43;).

Compared to other areas of the oral cavity, an edentulous posterior maxilla poses a unique challenge for implant placement. The most important aspect to consider is the maxillary sinus. This paper describes a case in which the bone ring technique was used to raise the floor of the maxillary sinus, followed by immediate implantation. A 37-year-old woman presented with a ridge defect in the left maxilla and the absence of teeth 26 and 27 (FDI tooth-numbering system) on the same side. The treatment plan involved the extraction of tooth 25, periodontal regeneration on the distal face of tooth 24, and concomitant raising of the maxillary sinus (using the bone ring technique) with simultaneous implantation. The bone ring technique promotes bone augmentation, raises the maxillary sinus, and reduces the surgical time, surgical costs, and length of the rehabilitation period. In the case presented herein, bone tissue stability around the implants, ridge maintenance, and gingival margin stability were found at the 1-year follow-up after rehabilitation.

In dental implant surgery, bone grafts are used for the reconstruction and reestablishment of alveolar bone volume and to improve bone architecture for better positioning of an implant. The present report describes the use of the bone ring technique for vertical and horizontal bone augmentation with simultaneous implant placement. This is a simple technique for acquiring donor bone in a ring shape and performing 3D reconstruction of bone defects, with an increase in the alveolar crest, using autogenous bone in a surgical procedure together with implant placement. Block bone grafts taken from the mentum can be used for predictable bone augmentation of up to 6 mm in the horizontal and vertical dimensions. The thickness of the bone ring collected from the mentum is very important. It cannot be too thin due to the risk of fracture, nor can it be too thick, as its contour could become deformed when placed in the receptor site. For stabilization and synthesis, a horizontal mattress suture is performed at the receptor site without promoting tension, and simple sutures are used for the complete co-optation of the flap and consequent stabilization of the clot. In the present type of bone defect, single-stage implant placement may be useful to shorten the overall treatment period.

This report describes a clinical case of severe Miller Class II gingival recession treated by two stages of surgery that combined a free gingival graft and connective tissue grafting. First, a free gingival graft (FGG) was performed to obtain an adequate keratinized tissue level. Three months later, a connective tissue graft (CTG) was performed to obtain root coverage. The results indicated that the FGG allows for a gain in the keratinized tissue level and the CTG allows for root coverage with decreased recession level after 16 months. Therefore, for this type of specific gingival recession, the combination of FGG and CTG can be used.
