Clinical Evaluation of the Long-Term Survival and Success Rates of Different Types of Implant-Supported Prostheses

Abstract

Background: Dental implants have been essential to the therapy of patients who are partially edentulous. Aim: Clinical evaluation of the long-term survival and success rates of different types of implant-supported prostheses. Materials and Methods: Patients who had a healthy edentulous ridge of three missing teeth in the posterior jaw in which two or three dental implants were placed having any of three prostheses, namely, three-unit fixed dental prostheses (FPD) on two implants, three splinted crowns on three implants, and three splinted crowns on three implants were included. Results: The survival rate in all patients with dental implants having different types of prostheses was 94.9%. The survival rate in FPD, three splinted crowns, and three nonsplinted crowns was 100, 88.5, and 93.6% respectively. Conclusion: FPD loaded on two dental implants was found to have a greater long-term survival rate and success rate with a lower frequency of peri-implantitis and prosthodontic complications.
