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

Dental implants have been essential to the therapy of patients who are partially edentulous. Clinical evaluation of the long-term survival and success rates of different types of implant-supported prostheses. 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. 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. 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.
