A Study on Materials Used and Longevity of Implant-Supported Prostheses

Abstract

Objective: This retrospective research was directed to investigate the longevity and maintenance requirements of implant-supported prostheses in subjects treated at a tertiary care center. Methods: Patient records of individuals who received implant-supported prostheses between January 2018 and December 2020 were retrospectively analyzed. Demographic information, implant type, prosthetic design, and follow-up data were collected. The primary outcomes assessed were prosthetic survival rates and the incidence of complications requiring maintenance interventions. Statistical analysis was performed to identify associations between demographic and clinical variables and the observed outcomes. Results: The research included 150 subjects with an average follow-up duration of 3 years. The overall survival rate of implant-supported prostheses was 90%, with 20% requiring maintenance interventions. Common complications included peri-implantitis (10%), prosthetic fracture (6%), and screw loosening (4%). Significant associations were found between smoking status and peri-implantitis (P < 0.05) and between prosthetic design and prosthetic fracture (P < 0.01). Conclusion: Implant-supported prostheses demonstrated a high overall longevity rate, with a subset of subjects requiring maintenance interventions due to complications. Peri-implantitis, prosthetic fracture, and screw loosening were the most prevalent complications, emphasizing the importance of tailored patient care and risk stratification.
