Abstract
Aim: The aim of this study was to evaluate the effect of PEEK abutments,\ran alternative to titanium abutments, with temporary acrylic restorations\rusing immediate loading protocol on the marginal bone loss and periimplant tissues.\rMethodology: This study was performed with temporary restorations\rusing 32 titanium and PEEK abutments (14 titanium and 18 PEEK) on 32\rimplants performed on 21 patients (13 females, 8 males). Before surgical\rplacement of the implants, intraoral and radiographic examinations were\rperformed. The patients were divided into two groups as titanium\rabutment group (Grup Ti) and PEEK abutment group (Grup PEEK). In both\rgroups, all implants were placed according to the manufacturer's\rrecommendations. After surgery, impressions were taken using polyvinyl\rsiloxane impression material and closed tray impression technique. The\rgingiva, which is thought to be formed on the model, was scraped and\rscrewed onto the appropriate titanium or PEEK abutment analogue\raccording to the groups and temporary restoration was prepared and\rapplied on the implant.\rResults: The results of the statistical analysis show that abutment types\rhave no significant effect on ISQ values (p>0.05), but the diameter of the\rimplant significantly affected ISQ values independently from abutment\rtype (p<0.05). Less marginal bone loss was observed in the PEEK abutment\rgroup compared to the titanium abutment group (p<005), and similar\rresults were obtained in both groups in terms of periodontal scores\r(p>0.05).\rConclusion: Within the limitations of this study, there was less bone loss\rin the PEEK abutment group (p<0.05). There was no difference between\rPEEK and titanium abutments in terms of ISQ values and clinical\revaluations (p>0.05).\r
