Comparison of Marginal Bone Loss Around Platform-Switched and Non-platform Switched Implants After Two Years of Placement

Abstract


Background. The present study was conducted to investigate the marginal bone loss around two different types of im-plant‒abutment junctions, called platform-switched (Implantium system) and non-platform switched (XiVE system) after two years of loading.
Methods. Sixty-four implants in 49 patients were included in the study. The implants were placed in the posterior mandi-bular region according to the relevant protocols. The extent of bone loss around the implants was measured and compared after 24 months, using digital parallel periapical radiographs.
Results. The means ± SE of bone loss values in the platform-switched and non-platform-switched groups were 0.47 ± 0.048 mm and 1.87 ± 0.124 mm, respectively. The difference between the two groups was statistically significant (P < 0.0001).
Conclusion. The platform-switching technique seems to reduce the peri-implant crestal bone resorption, which supports the long-term predictability of implant therapy.
