Retrospective Evaluation of Prosthetic Complications and Peri-implant Bone Resorption in Implant-supported Single Unit Fixed Restorations

In this retrospective study, 100 volunteer patients, aged between 20 and 64, who received implant-supported single-member fixed restoration treatment, were scanned from the archives and included. The patients were scanned from the archives, called for 12-month follow-ups, and clinical and radiographic evaluations were made. G*Power (G*Power Ver. 3.0.10, Franz Faul, Üniversität Kiel, Germany) package program was used to calculate the sample size. Digital radiographs (periapical-panoramic films) taken from the patients at the end of the implant treatment and at the 12th month follow-up were recorded using Planmeca Romexis® software. ImageJ, a digital image analysis program, was used to evaluate marginal bone loss on radiographs (ImageJ 1.54g- Wayne Rasband and Contributons, National institutes of Health, USA). In evaluating the success and survival of the implants, the criteria in the consensus decisions published at the International Oral Implantology Congress in 2007 were taken as basis. In addition, prosthetic complications such as chipping, screw loosening and decementation; Its relationship with anatomical localization, implant length, implant diameter, abutment type, superstructure material, occlusal table and the condition of the opposing arch was evaluated.
