Summary
Resin-bonded fixed partial dentures (RBFPDs) can achieve long-term success with rebonding. Factors like etiology and periodontal support significantly influence RBFPD survival rates, indicating potential for semi-permanent restorations.
Area of Science:
- Dental Materials Science
- Prosthodontics
- Clinical Dentistry
Background:
- Resin-bonded fixed partial dentures (RBFPDs) are a conservative treatment option for missing teeth.
- Long-term survival data for RBFPDs under various clinical conditions are crucial for treatment planning.
Purpose of the Study:
- To evaluate the long-term survival rates of 51 resin-bonded fixed partial dentures (RBFPDs) over 13 years.
- To investigate the influence of etiological factors, location, and number of units on RBFPD survival.
- To assess the impact of rebonding on RBFPD functional survival.
Main Methods:
- Prospective clinical study involving 51 RBFPD insertions.
- Kaplan-Meier procedure for determining mean survival times and confidence levels.
- Cox regression analysis to calculate relative risks for various factors.
Main Results:
- Overall complete survival rate was 85 months +/- 13%.
- Functional survival increased to 112 months +/- 10% with one rebonding and 131 months +/- 8% with multiple rebondings.
- RBFPDs placed in cases of trauma without prior orthodontic or periodontal treatment showed significantly higher survival rates.
Conclusions:
- RBFPDs can serve as long-term or semi-permanent restorations, especially when placed under optimal conditions.
- Rebonding is an effective strategy to enhance the functional survival of RBFPDs.
- Etiology and the need for prior periodontal or orthodontic treatment are significant predictors of RBFPD success.
