Titanium surface is an important factor in achieving osseointegration during the early wound healing of dental implants in alveolar bone. The purpose of this study was to evaluate sandblasted-etched surface implants to investigate the osseointegration. In the present study, we used two different types of sandblasted-etched surface implants, an SLA™ surface and a Nanoblast Plus™ surface. Roughness and chemical composition were evaluated by a white light interferometer microscope and X-ray photoelectron spectroscopy, respectively. The SLA™ surface exhibited the higher values (Ra 3.05 μm) of rugosity compared to the Nanoblast Plus™ surface (Ra 1.78 μm). Both types of implants were inserted in the femoral condyles of ten New Zealand white rabbits. After 12 weeks, histological and histomorphometric analysis was performed. All the implants were osseointegrated and no signs of infection were observed. Histomorphometric analysis revealed that the bone–implant contact % (BIC) ratio was similar around the SLA™ implants (63.74 ± 13.61) than around the Nanoblast Plus™ implants (62.83 ± 9.91). Both implant surfaces demonstrated a favorable bone response, confirming the relevance of the sandblasted-etched surface on implant osseointegration.

The purpose of this study was to compare side-by-side two different titanium screw-type implants in the maxillae of miniature pigs. The test implants had a machined and acid-etched surface (Osseotite) whereas the control implants were sandblasted and acid-etched (SLA). After 4, 8, and 12 weeks of healing, removal torque testing was performed to evaluate the shear strength of the bone-implant interface for both implant types. The results demonstrated significant differences between both implant types (P < .01). Osseotite implants revealed mean removal torque values (RTV) of 62.5 Ncm at 4 weeks, 87.6 Ncm at 8 weeks, and 95.7 Ncm at 12 weeks of healing. In contrast, the SLA implants demonstrated mean RTV of 109.6 Ncm, 196.7 Ncm, and 186.8 Ncm at corresponding healing periods. The mean RTV for SLA implants was 75% to 125% higher than for Osseotite implants up to 3 months of healing. [ABSTRACT FROM AUTHOR]

Introduction. Implant dentistry constitute an important option in the prosthodontic treatment of patients with partial and total tooth loss. This long-term study reports the evaluation of patients treated by early loading of implants with internal connection and sandblasted-acidetched surface. Methods. 40 patients with tooth loss were treated with Frontier GMI ® sandblasted and acid-etched surfa ce implants. Implants were loaded after a healing free-loading period of 6 weeks (mandible) and 8 weeks (maxilla). Clinical findings (implants and prosthodontics) were followed during at least 6 years. Results. 103 implants were inserted (46 maxillary (44.7%), and 57 mandibular (55.3%)) for prosthodontic rehabilitation. 37 implants (35.9%) were inserted in anterior sites and 66 implant (64.1%) in posterior sites. Seventy implants (68%) were placed submerged (two stages) while that 33 implants (32%) were placed nonsubmerged (one stage). After at a mean follow-up of 92.2 months, clinical results indicate a survival rate of implants of 96.2%. Four implants were lost during the treatment. Mean marginal bone loss were 0.99 ± 0.84 mm. Prosthodontic restorations included 31 single crowns, 15 fixed bridges, 5 overdentures, 2 fixed totally rehabilitation and an hybrid full rehabilitation. Delayed complications include 11 implants (10.7%) with peri-implantitis and 6 prostheses (11.1%) with technical complications. Conclusions. Clinical results of this study indicate that prosthodontic rehabilitation by early loading of internal connection and sandblasted and etched- implants can be a successful dental treatment.

Purpose: The aim of this study was to evaluate bone apposition to a modified sandblasted and acid-etched (SLA) implant surface (modSLA) in the canine mandible as compared with the standard SLA surface. Material and methods: In this experimental study, all mandibular premolars and first molars were extracted bilaterally in five foxhounds. After a healing period of 6 months, each side of the mandible received six randomly assigned dental implants alternating between the standard SLA and modSLA surface. The dogs were sacrificed at 2 weeks ( n=2) or 4 weeks ( n=3) after implant placement. Histologic and histomorphometric analyses were then performed for each implant. Results: The microscopic healing patterns at weeks 2 and 4 for the two implant types with the standard SLA and modSLA surfaces showed similar qualitative findings. New bone tissue had already established direct contact with implant surfaces after 2 weeks of healing. The mean percentage of newly formed bone in contact with the implant (BIC) was significantly greater for modSLA (28.2±7.9%) than for SLA (22.2±7.3%) ( P<0.05). This difference was no longer evident after 4 weeks. An increase in BIC for both implant surface types occurred from weeks 2 to 4. This increase was statistically significant when compared with SLA at 2 weeks ( P<0.05), but not when compared with modSLA at 2 weeks. Conclusion: The data from the present study demonstrate significantly more bone apposition for the modSLA surface than the standard SLA surface after 2 weeks of healing. This increased bone apposition may allow a further reduction of the healing period following implant placement for patients undergoing early loading procedures. [ABSTRACT FROM AUTHOR]

The aim of the present pilot study was to histologically/immunohistochemically investigate initial and early subepithelial connective tissue attachment at transmucosal parts of modified (mod) and conventional sandblasted, large grit and acid-etched (SLA) titanium implants. Implantation of modSLA and SLA implants was performed bilaterally in both the mandible and maxilla of four beagle dogs. The implants were submerged to prevent bacterial contamination. The animals were killed after 1, 4, 7 and 14 days. Peri-implant tissue reactions were assessed histologically (Masson Goldner Trichrome stain-MG) and immunohistochemically (IH) using monoclonal antibodies to fibronectin (FN) and proliferating cell nuclear antigen (PCNA). The surgical procedure of implant submerging resulted in the formation of an artificial gap in the transmucosal area of both types of implants. After 14 days of healing, MG stain revealed the formation of well-organized collagen fibres and numerous blood vessels in a newly formed loose connective tissue zone adjacent to modSLA. While some fibres were oriented in a parallel direction, others have started to extend and attach partially perpendicular to the implant surface. In contrast, SLA implants appeared to be clearly separated by a dense connective tissue zone with parallel-running collagen fibres and rare blood vessel formation. First signs of a positive FN and PCNA staining adjacent to both implant surfaces were observed at day 4. Within the limits of a pilot study, it might be concluded that modSLA titanium surfaces might possess the potential to promote subepithelial connective tissue attachment at the transmucosal part of the implant.

Objectives: The aim of the present pilot study was to investigate initial and early tissue reactions to modified (mod) and conventional sand-blasted, large grit and acid-etched (SLA) titanium implants. Material and methods: Implantation of modSLA and SLA implants was performed bilaterally in both the mandible and maxilla of dogs. The animals were sacrificed after a healing period of 1, 4, 7 and 14 days, respectively. Peri-implant tissue reactions were assessed in non-decalcified tissue sections using conventional histology (Toluidine blue-TB and Masson Goldner Trichrome stain-MG) and immunohistochemistry using monoclonal antibodies to transglutaminase II (TG) (angiogenesis) and osteocalcin (OC). Bone density (BD) and bone to implant contact (BIC) were assessed histomorphometrically. Results: Day 1 revealed an early TG antigen reactivity in the provisional fibrin matrix adjacent to both implant surfaces. Day 4 was characterized by the formation of a collagen-rich connective tissue (MG), which revealed the first signs of OC synthesis adjacent to modSLA surfaces. Immunohistochemical staining for TG revealed a direct correlation between angiogenesis and new bone formation, which was clearly identifiable after 7 days by means of increasing BD, BIC and OC values. After 14 days, modSLA surfaces seemed to be surrounded by a firmly attached mature, parallel-fibered woven bone. Conclusions: Within the limits of the present study, it might be concluded that the combination of immunohistochemical and conventional histological stainings in non-decalcified tissue sections is a valuable technique to evaluate the initial and early stages of wound healing around endosseous titanium implants.

Objectives: The aim of the present study was to evaluate bone regeneration in dehiscence-type defects at titanium implants with chemically modified (mod) and conventional sand-blasted/acid-etched (SLA) surfaces. Material and Methods: Standardized buccal dehiscence defects (height: 3 mm, width: 3 mm) were surgically created following implant site preparation in both the upper and lower jaws of four beagle dogs. modSLA and SLA implants were inserted bilaterally according to a split-mouth design. The animals were sacrificed after 2 and 12 weeks ( n=2 animals each). Dissected blocks were processed for histomorphometrical analysis: defect length, new bone height (NBH), percent linear fill (PLF), percent of bone-to-implant contact (BIC-D) and area of new bone fill (BF). Results: Wound healing at SLA implants was predominantly characterized by the formation of a dense connective tissue at 2 and 12 weeks, without significant increases in mean NBH, PLF, BIC-D or BF values. In contrast, modSLA implants exhibited a complete defect fill at 12 weeks following implant placement. In particular, histomorphometrical analysis revealed the following mean values at 12 weeks: NBH (3.2±0.3 mm), PLF (98%), BIC-D (82%) and BF (2.3±0.4 mm2). Conclusion: Within the limits of the present study, it was concluded that modSLA titanium surfaces may promote bone regeneration in acute-type buccal dehiscence defects at submerged implants.

Microrough titanium (Ti) surfaces of dental implants have demonstrated more rapid and greater bone apposition when compared with machined Ti surfaces. However, further enhancement of osteoblastic activity and bone apposition by bio-functionalizing the implant surface with a monomolecular adsorbed layer of a co-polymer – i.e., poly(l-lysine)- graft-poly(ethylene glycol) (PLL -g-PEG) and its derivatives (PLL -g-PEG/PEG-peptide) – has never been investigated. The aim of the present study was to examine early bone apposition to a modified sandblasted and acid-etched (SLA) surface coated with an Arg–Gly–Asp (RGD)-peptide-modified polymer (PLL -g-PEG/PEG–RGD) in the maxillae of miniature pigs, and to compare it with the standard SLA surface. Test and control implants had the same microrough topography (SLA), but differed in their surface chemistry (polymer coatings). The following surfaces were examined histomorphometrically: (i) control – SLA without coating; (ii) (PLL -g-PEG); (iii) (PLL -g-PEG/PEG–R ) (RDG, Arg–Asp–Gly); and (iv) (PLL -g-PEG/PEG–RGD). At 2 weeks, RGD-coated implants demonstrated significantly higher percentages of bone-to-implant contact as compared with controls (61.68% vs. 43.62%; P<0.001). It can be concluded that the (PLL -g-PEG/PEG–RGD) coatings may promote enhanced bone apposition during the early stages of bone regeneration. [ABSTRACT FROM AUTHOR]

Increased surface roughness of dental implants has demonstrated greater bone apposition; however, the effect of modifying surface chemistry remains unknown. In the present study, we evaluated bone apposition to a modified sandblasted/acid-etched (modSLA) titanium surface, as compared with a standard SLA surface, during early stages of bone regeneration. Experimental implants were placed in miniature pigs, creating 2 circular bone defects. Test and control implants had the same topography, but differed in surface chemistry. We created the test surface by submerging the implant in an isotonic NaCl solution following acid-etching to avoid contamination with molecules from the atmosphere. Test implants demonstrated a significantly greater mean percentage of bone-implant contact as compared with controls at 2 (49.30 vs. 29.42%; p = 0.017) and 4 wks (81.91 vs. 66.57%; p = 0.011) of healing. At 8 wks, similar results were observed. It is concluded that the modSLA surface promoted enhanced bone apposition during early stages of bone regeneration. [ABSTRACT FROM AUTHOR]

Titanium surface is an important factor in achieving osseointegration during the early wound healing of dental implants in alveolar bone. The purpose of this study was to evaluate sandblasted-etched surface implants to investigate the osseointegration. In the present study, we used two different types of sandblasted-etched surface implants, an SLA™ surface and a Nanoblast Plus™ surface. Roughness and chemical composition were evaluated by a white light interferometer microscope and X-ray photoelectron spectroscopy, respectively. The SLA™ surface exhibited the higher values (Ra 3.05 μm) of rugosity compared to the Nanoblast Plus™ surface (Ra 1.78 μm). Both types of implants were inserted in the femoral condyles of ten New Zealand white rabbits. After 12 weeks, histological and histomorphometric analysis was performed. All the implants were osseointegrated and no signs of infection were observed. Histomorphometric analysis revealed that the bone–implant contact % (BIC) ratio was similar around the SLA™ implants (63.74 ± 13.61) than around the Nanoblast Plus™ implants (62.83 ± 9.91). Both implant surfaces demonstrated a favorable bone response, confirming the relevance of the sandblasted-etched surface on implant osseointegration. [ABSTRACT FROM AUTHOR]

- Abstract
IIntroducción: La implantología oral representa en la actualidad, una modalidad terapéutica odontológica en los pacientes con pérdida dental total y parcial. El estudio muestra la evaluación de los pacientes tratados con coronas unitarias mediante la carga de los implantes unitarios. Métodos: Fueron tratados146 pacientes con pérdidas dentales unitarias con implantes con superficie arenada y grabada Galimplant®. Los implantes fueron cargados funcionalmente tras un periodo de tiempo de 6 semanas en la mandíbula y 8 semanas en el maxilar superior. Los hallazgos clínicos (implantológicos y prostodóncicos) se han seguido durante 5 años. Resultado: Fueron insertados 216 implantes en ambos maxilares (168 en el maxilar superior y 48 en la mandíbula) para su rehabilitación prostodóncica con coronas implantosoportadas. 81 implantes fueron insertados en el sector anterior y 135 implantes en el sector posterior. Después de 5 años de seguimiento clínico, los resultados indican una supervivencia y éxito de los implantes del 95,8%.

Introducción: En la actualidad, la implantología oral constituye una modalidad terapéutica en el tratamiento prostodóncico de los pacientes mayores edéntulos totales. El estudio muestra la evaluación del tratamiento con sobredentaduras mandibulares mediante la carga precoz de implantes dentales. Métodos: Treinta pacientes edéntulos totales fueron tratados con 60 implantes con superficie arenada y grabada Galimplant® en la mandíbula para su rehabilitación prostodóncica con sobredentaduras. Dos implantes fueron insertados en cada paciente. Los implantes fueron cargados funcionalmente tras un periodo de tiempo de 6 semanas con retenedores de fricción. Los hallazgos clínicos (implantológicos y prostodóncicos) se han seguido durante al menos 24 meses. Resultados: Los resultados indican una supervivencia y éxito de los implantes del 98,3%. Durante el periodo de cicatrización libre de carga funcional, se perdió un implante por movilidad. La pérdida de hueso marginal media fue de 0,4 mm (0-1,1 mm). El 100% de los pacientes fueron tratados mediante una sobredentadura implantorretenida con anclajes de fricción. En cuatro pacientes se realizaron cambios en los componentes plásticos de los ataches. El seguimiento clínico medio fue de 40,8 meses (24-60 meses). Conclusiones: Los resultados del presente estudio indican que la rehabilitación prostodóncica mediante la carga precoz con sobredentaduras con implantes de los pacientes edéntulos mandibulares representa una terapéutica implantológica con éxito. Introduction: Today, oral implantology constitute a therapeutic modality in the prosthodontic treatment of totally edentulous patients. This study reports the evaluation of treatment with overdentures in the mandible by early loading of dental implants. Methods: 30 edentulous patients were treated with 60 Galimplant® sand-blasted and acid-etched surface implants for prosthodontic rehabilitation with overdentures in the mandible. Two implants were inserted in each patient. Implants were loaded after a healing free-loading period between 6 weeks with locator attaches. Clinical findings (implant and prosthodontics) were followed during at least 24 months. Results: Clinical results indicate a survival and success rate of implants of 98,3%. One implant was lost during the healing period. Media marginal bone loss was 0.4 mm (0-1.1 mm). 100% of patients were treated with overdentures retained with 2 implants with locator attaches. Changes in plastic components of attaches were reported in 4 patients. The media follow-up was of 40.8 months (24-60 months). Conclusions: Clinical results of this study indicate that prosthodontic rehabilitation in the mandible of edentulous patients with early loading of overdentures supported by implants is a successful implant treatment.

Introducción: La implantología oral representa en la actualidad, una modalidad terapéutica odontológica en los pacientes con pérdida dental total y parcial. El estudio muestra la evaluación de los pacientes tratados mediante carga precoz de implantes de titanio con conexión interna y superficie arenada y grabada. Métodos: 39 pacientes con pérdidas dentales fueron tratados con implantes con conexión interna y superficie arenada y grabada Frontier GMI®. Los implantes fueron cargados funcionalmente tras un periodo de tiempo de 6 semanas en la mandíbula y 8 semanas en el maxilar superior. Los hallazgos clínicos (implantológicos y prostodóncicos) se han seguido durante 1 año. Resultados: 111 implantes fueron insertados en ambos maxilares (50 en el maxilar superior y 61 en la mandíbula) para su rehabilitación prostodóncica. 44 implantes fueron insertados en el sector anterior y 67 implantes en el sector posterior. Después de 1 año de seguimiento clínico, los resultados indican una supervivencia y éxito de los implantes del 99,1%. Durante el periodo de cicatrización libre de carga funcional, se perdió 1 implante por movilidad. Como complicaciones tardías hubo un caso de periimplantitis. Las restauraciones prostodóncicas incluyeron 30 coronas unitarias, 15 puentes fijos, 5 sobredentaduras con bolas y 2 rehabilitaciones totales fijas. Conclusiones: Los hallazgos clínicos del presente estudio indican que la rehabilitación prostodóncica mediante la inserción de implantes de titanio con conexión interna y superficie arenada + grabada, y cargados precozmente, representa una terapéutica odontológica con éxito elevado. Introduction: Today, oral implantology constitute a therapeutic modality in the prosthodontic treatment of patients with partial and total tooth loss. This study reports the evaluation of patients treated by early loading of titanium implants with internal connection and sandblasted-acid-etched surface. Methods: 39 patients with tooth loss were treated with Frontier GMI® sandblasted and acid-etched surface implants. Implants were loaded after a healing free-loading period of 6 weeks (mandible) and 8 weeks (maxilla). Clinical findings (implants and prosthodontics) were followed during 1 year. Results: 111 implants were inserted (50 maxillary, and 61 mandibular) for prosthodontic rehabilitation. 44 implants were inserted in anterior sites and 67 in posterior sites. After 1-year follow-up, clinical results indicate a survival and success rate of implants of 99.1%. One implant were lost during the healing period by mobility. A case of periimplantitis were reported as late complication after functional loading. Prosthodontic restorations included 30 single crowns, 15 fixed bridges, 5 ball-overdentures and 2 fixed totally rehabilitation. Conclusions: Clinical results of this study indicate that prosthodontic rehabilitation supported by internal connection and sandblasted and etched-titanium implants and loaded early can be a successful dental treatment.
