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

Completed

• Conditions: Implant Clinical Survival; Restoration Survival

• Registration Number: NCT06709508
• Lead Sponsor: Özer İşisağ

Brief Summary

This study evaluated the one-year outcomes of implant-supported single-tooth fixed restorations used to replace missing teeth. The aim was to assess the success rates of dental implants and identify potential complications during treatment. A total of 100 individuals aged between 20 and 64 participated in the study. Patients were evaluated one year after their implant treatments through clinical examinations and radiographic imaging.

Detailed Description

Aim: The aim of this study was to retrospectively investigate the prosthetic complications and peri-implant bone loss by clinical and radiological examination at the 12th month of implantsupported single-unit fixed restorations.

Materials and Methods: 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.
