Evaluation average of marginal bone loss around platform switched and non platform switched implants 2 years after loading
Abstract
The implant is latest treatment method for replacing of lost teeth, but absorption of marginal bone around the implants is a threat to the long-term durability of the implants. The aim of present clinical study was to assess the marginal bone loss around two difference types of implant-abutment junction called plateform-switched and non-platform switched after two years loading. Materials and Methods: A total of 64 implants in 49 patients were included in the study. The implants were placed based on the relevant protocol in posterior mandibular rigion I? Standardized peri apical radiographs were obtained for evaluation of bone Loss around implants after 2 years loading . average of marginal bone loss around plateform-switched and non-platform switched implants were measured . The collected data was analyzed using descriptive statistical methods (mean and standard deviation) and Man-U-Whitney test, and SPSS.17software. In this study, P<0.05 was regarded statistically meaningful. Results: The mean bone loss values in the platform switched and non-platform switched groups was 0.47mm 0.36mm and 1.89 mm0.62mm, respectively, with no statistically significant difference based on the outcomes of statically analysis (P< 0.0001). Conclusion: platform-switched seems to reduce peri-implant crestal bone resorption and increase the long term predictability of implant therapy.
