Effects of abutment materials on the tissues surrounding dental implants immediately after loading: An in vivo study

Aim: The aim of this study was to evaluate the effect of PEEK abutments, an alternative to titanium abutments, with temporary acrylic restorations using immediate loading protocol on the marginal bone loss and peri-implant tissues. Methodology: This study was performed with temporary restorations using 32 titanium and PEEK abutments (14 titanium and 18 PEEK) on 32 implants performed on 21 patients (13 females, 8 males). Before surgical placement of the implants, intraoral and radiographic examinations were performed. The patients were divided into two groups as titanium abutment group (Grup Ti) and PEEK abutment group (Grup PEEK). In both groups, all implants were placed according to the manufacturer's recommendations. After surgery, impressions were taken using polyvinyl siloxane impression material and closed tray impression technique. The gingiva, which is thought to be formed on the model, was scraped and screwed onto the appropriate titanium or PEEK abutment analogue according to the groups and temporary restoration was prepared and applied on the implant. Results: The results of the statistical analysis show that abutment types have no significant effect on ISQ values (p>0.05), but the diameter of the implant significantly affected ISQ values independently from abutment type (p0.05). Conclusion: Within the limitations of this study, there was less bone loss in the PEEK abutment group (p0.05). How to cite this article: Gül İ, Zortuk M, Öztürk C.
