Resin-bonded fixed partial dentures with metal framework a report of 49 cases followed for 2 years

Purpose: The survival rates of 49 cast metal resin-bonded fixed partial denture (RBFPD) were evaluated in this clinical study for a period up to 30 months. Method and materials: Forty-four patients with a total of 49resin-bonded fixed partial denture (RBFPD) placed between 2010 and 2012were examined after 6-month periods for up to 30 month. Originally, there were 50 patients (the drop-out rate was12%). Partial or complete total debonding of the RBFPD was considered a treatment failure. The data were analyzed with Kaplan-Meier survival test (α=.05). The probability of survival was calculatedfor location anterior/posterior and maxilla/mandible. Result: Eight frameworks were debonded. The survival rate calculated using the Kaplan-Meier method (α=.05)at 30 months was 76 %. Only slight but not statistically significant differences between the covariates maxilla/mandible, anterior/ posterior were observed. Six of the failed RBFPDs were rebonded. Conclusion: Within the limitations of this study, RBFPDs with cast metal framework seem to be a reliable restorative alternative during a short-term period.
