Summary
Implant-supported fixed partial prostheses demonstrate a high survival rate and excellent patient satisfaction. Rehabilitation with these prostheses offers a favorable prognosis and positive patient experience.
Area of Science:
- Dental Implantology
- Prosthodontics
- Biomaterials
Background:
- Implant-supported fixed partial prostheses (IFPPs) are a common restorative option.
- Assessing long-term outcomes and patient acceptance is crucial for clinical practice.
Purpose of the Study:
- To evaluate the treatment outcomes of IFPPs.
- To assess patient reactions and satisfaction with IFPP rehabilitation.
Main Methods:
- Retrospective analysis of 83 patients treated with IFPPs (Brånemark system) between 1986-1995.
- Follow-up examination of 76 patients with a mean observation period of 53.9 months.
- Evaluation of 285 implants and 102 prostheses, including screw joint stability and marginal bone loss.
Main Results:
- A 96% implant survival rate was observed, including those in augmented bone.
- Prostheses with cantilevers showed higher screw loosening rates, though not statistically significant.
- Mean marginal bone loss was minimal (<0.1 mm/year after the first year).
- Metal-ceramic restorations had fewer complications than gold-acrylic or titanium-acrylic prostheses.
- Patients reported high satisfaction with esthetics, comfort, and overall function.
Conclusions:
- IFPPs exhibit a very good prognosis for long-term success.
- Patient acceptance and satisfaction with IFPPs are notably high.
