Treatment outcomes of patients with implant-supported fixed partial prostheses
1Department of Clinical Dental Sciences, Faculty of Dentistry, University of British Columbia, Vancouver, Canada.
Summary
Brånemark implant-supported fixed prostheses demonstrate high success rates in partially edentulous patients. This study shows a 94% implant success and 97% prosthesis stability over a mean of 5.41 years.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials
Background:
- Partially edentulous patients often require fixed prostheses.
- Dental implants offer a solution for restoring function and aesthetics.
- Long-term success of implant-supported prostheses is crucial for patient outcomes.
Purpose of the Study:
- To evaluate the long-term success and stability of Brånemark implant-supported fixed partial prostheses.
- To analyze implant survival rates based on location and arch.
- To assess prosthesis stability in a cohort of partially edentulous patients.
Main Methods:
- Prospective documentation of 97 fixed prostheses supported by 230 Brånemark implants.
- Study included 77 partially edentulous patients.
- Follow-up period up to 12 years, with a mean of 5.41 years.
Main Results:
- Overall implant success rate of 94%.
- Continuous prosthesis stability rate of 97%.
- No significant difference in implant loss between different anatomical zones (I and II) or between the maxilla and mandible.
Conclusions:
- Brånemark implant-supported fixed partial prostheses are highly efficacious for treating partially edentulous patients.
- The treatment demonstrates excellent long-term predictability and stability.
- Implant placement location does not significantly impact survival rates.
