Abstract

Abstract
Purpose: The aim of the study is to evaluate the effect of using two different abutment materials; BioHPP and cobalt-chromium on the supporting structure of implant retained telescopic mandibular overdenture by radiographic analysis.
Methodology: Fourteen completely edentulous patients were selected from Removable Prosthodontics Department, AinShams University according to the inclusion and exclusion criteria. All patients received implant assisted telescopic mandibular overdenture. After osseointegration, CAD/CAM technology was used for fabrication of primary and secondary copings of the first group by milling wax then they were casted into cobalt chromium alloy while in the other group the primary and secondary copings were made from BioHPP material by CAD/CAM milling. Crestal bone loss was measured using cone beam CT at overdenture insertion, at 6 months and at one year follow-up.
Results: The results of this study showed statistically significant difference between both groups where a lesser bone loss was observed in the BioHPP group at six months and at one year follow-up.
Conclusion: Within the limitations of the follow up period, it could be concluded that the use of BioHPP material as implant abutments in telescopic mandibular implant overdenture can make a lesser bone loss than the conventional cobalt chromium copings over one year follow up.
Keywords: BioHPP, Cobalt chromium, Implant retained telescopic overdenture, Cone Beam CT.
