Retrospective study of marginal bone change in 1 year loading of INNO® dental implant

Introduction: The marginal bone change of 1 year loading was evaluated in the non-microthread collar and platform switching structured INNO® dental implant of which the surface is treated with the RBM sandblasting, hyper-thermal acid etching and alkali solution cleaning process for hydrophilic macroand micro-porosity. Material and Methods: A total of 144 implants were placed in the healed ridge and extraction socket with periodontal and periapical lesion. Patient data were evaluated to acquire implant survival rates, gender, implant diameter, length, extraction socket, periodontal lesion with periapical lesion, loading time, adjacent tooth, opposing tooth and kind of prosthesis. Panoramic X-rays were analyzed for marginal bone loss. Results: Average follow-up time was 13.4 months. Survival rate was 98.2% (2 implant lost). A average marginal bone loss was 0.027± 0.138 mm in total 142 implants. Bone loss in sixty four of the short 8 mm implant was not significantly different with long implants. Marginal bone loss was not significantly different in the immediate (46 implants) and late implant placement (98 implants) and in the implants placed in socket (24 implants) of periodontitis with periapical lesion and the other (120 implants). Conclusion: Within the limitations of this study, we conclude that INNO® dental implant have equal survival rates to the others of platform switched implants. Marginal bone loss was low even in the short length implant, immediate implant placement and the socket of periodontitis with periapical lesion, compared to the other clinical results.
