EVALUATION OF FACTORS RELATED TO THE OUTCOME OF SCREW-RETAINED TEMPORARY FIXED PROSTHESES FOLLOWING THE IMMEDIATE PLACEMENT OF 04 IMPLANTS IN PATIENTS WITH COMPLETE EDENTULISM OF THE MAXILLA
Main Article Content
Abstract
Background: Fixed prostheses for fully edentulous patients are becoming increasingly common. Beside of functions protecting soft tissues and jawbones, this type of restoration also helps patients be more confident in daily communication. The concept “All-on-4” using immediate implant associated with immediate loading of temporary prosthese, is being increasingly implemented with many advantages. Objective: Evaluation of Factors Related to the Success of Immediate Load Screw-Retained Temporary Fixed Prostheses on 04 Implants in Two Aspects: Osseointegration and Peri-Implant Crestal Bone Loss. Material and methods: A total of 35 patients with complete tooth loss in the upper jaw, who required restoration using the placement of four implants at Thu Duc Regional General Hospital from May 20, 2023, to April 30, 2024, were included. Results: The average age was 59.6 ± 9.5 years, with males accounting for 71.4% of the participants. The success rate was 94.3% after a follow-up period of 6 to 12 months. Among the total of 140 implants placed and immediately loaded, 97.9% achieved successful osseointegration. The average crestal bone loss around the implant neck was 0.11 ± 0.19 mm, and factors associated with bone loss included male gender, larger implant diameter, and immediate implant placement following tooth extraction. Conclusion: Temporary fixed prothese associated with immediate loading on 04 implants in patients with fully edentulous maxilla, has a high success rate. The average level of bone loss was related to the patient's gender, implant diameter, and initial tooth loss.
