Abstract
Objectives: To evaluate the effect of osseodensification concept using Densah bur on implant primary stability and peri-mplant bone density in maxillary implant overdenture. Materials and Methods: Ten completely edentulous patients were selected and two implants were inserted in the maxilla for each patient in a split mouth study design; one implant with the conventional drilling system and one implant with the Densah bur drilling system. Implant primary stability was assessed using ostell device at the time of implant placement and at prosthetic rehabilitation phase (4m). Bone density around the implants was measured using CBCT at 3,6,12 months intervals. Results: significant difference was found regarding Osstell values as well as bone density measurements between both groups throughout the study period Conclusions: Within the limitation of this study, Densah drilling burs that adopt the osseodensification concept have displayed more primary stability compared to the conventional drilling protocol in terms of primary stability as well as bone density for delayed loaded implants used to retain and support maxillary overdentures.
Key words: implants, primary stability, osseodensification, bone density, overdenture.
