Abstract | Objectives:
Two-unit cantilevered resin-bonded fixed partial dentures (RBFPDs) offer long-term retention for anterior and premolar-sized spans. At this center, molar and longer spans have been restored with fixed-movable (FM) RBFPDs to overcome the lower retention rates of fixed-fixed RBFPDs. This retrospective study aimed to evaluate the long-term longevity and the patient-reported outcomes of posterior FM-RBFPDs.
Methods:
Posterior FM-RBFPDs that had been inserted at least five years were reviewed. Survival was “retention of the original prosthesis in mouth” and success was “survival of prosthesis and absence of complications requiring treatment intervention”. Prosthesis location, number of units, insertion year, tooth/teeth replaced and operator experience were collected. Patients’ acceptance to FM-RBFPDs were assessed using prosthesis satisfaction questionnaire and Oral Health Impact Profile (OHIP-49). Results were analyzed using log-rank and cox-regression tests at significance level α = 0.05.
Results:
One-hundred-and-one prostheses were examined. The mean observation time was 126.4 ± 32.2 months. Thirty-six (35.6%) and 63 (62.4%) FM-RBFPDs were rated as success and survival respectively. Prostheses inserted after year 2001 (n = 69) experienced 42.0% (n = 29) success and 75.4% (n = 52) survival, and its survival rate was significantly better than those inserted in or before 2001 (p = 0.01). Five- and ten-year cumulative survival probability of FM-RBFPDs inserted after year 2001 were 82.3% and 74.1% respectively. The most frequent complications were debonding among 34 (33.7%) prostheses. Patients’ acceptance were high.
Conclusions:
More recently inserted prostheses showed improved longevity and patients’ acceptance to posterior FM-RBFPDs were high.
Clinical significance:
Fix-Movable RBFPDs are a viable tooth replacement option in the posterior region. |
