Abstract

The aim of this study is evaluate on radiographic examination bone resorption on tilted implants placed with a minimal angulation of 15 degrees compared with the occlusal plane. The purpose is to demonstrate if a correlation between tilted implants and crestal bone resorption exist. In this study we evaluated orthopantomography done at T0 moment when implants have been loaded and at T1 moment: between 1 and 10 years from loading. Values are calculated using a specific program: we have measured the importance of bone resorption in mm both mesial and distal from the implant surface and catalogued only implants with more then 15 degrees angulation. This study demonstrated that the use of tilted implants is safe and is not associated to a higher marginal bone loss as compared to axially placed implants: no statistically significant difference in implant success was observed. Obviously is compulsory evaluate different aspects: for example if the implant is rehabilitated individually or if is in a full-arch fixed restoration, or if the implant is located in natural bone or in presence of bone grafted. This study demonstrate that increasing of angulation of implant insertion doesn’t mean necessary an increasing of implant failure; considering different variables is necessary to obtain a predictable study. New studies with a larger number of patients and implants inserted are essentials.
