Summary
Resin-bonded fixed partial dentures showed an 85% survival rate at 5 years and 71% at 10 years. Using dental dam during cementation significantly reduced debonding risk for these prostheses.
Area of Science:
- Prosthodontics
- Dental Materials Science
- Clinical Dentistry
Background:
- Resin-bonded fixed partial dentures (RBFPDs) offer a conservative treatment option.
- Long-term survival data for RBFPDs are crucial for clinical decision-making.
- Evaluating factors influencing RBFPD longevity is essential.
Purpose of the Study:
- To assess the survival rate of RBFPDs placed between 1993 and 2003.
- To identify factors affecting the survival of RBFPDs in a university and private practice setting.
Main Methods:
- Retrospective analysis of RBFPDs.
- Inclusion of variables: preparation design, alloy type, surface treatment, cementation isolation, cement type, prosthesis type, abutment number, and missing tooth count.
- Survival probability estimation.
Main Results:
- Estimated survival probability was 85% at 5 years and 71% at 10 years.
- No significant differences in survival rates were observed for most evaluated parameters.
Conclusions:
- The use of dental dam during cementation is associated with a reduced risk of debonding for RBFPDs.
- Further research may explore specific material or procedural optimizations.
