Objective:
To observe a short-term clinical effect of pin-ledge retained metal plate resin-bonded fixed partial denture (RBFPD).
Methods:
Sixty-five patients were restored with the pin-ledge retained metal plate RBFPD. Retention and marginal integrity of RBFPDs, secondary caries and mobility of abutments, and gingival bleeding index were clinically evaluated immediately after cementation and every 6-month period later. The parallel irradiating X-ray films were also taken to evaluate alveolar bone resorption.
Results:
A total of 74 RBFPDs were made for all 65 patients. The mean follow-up period was 12.4 months. There were three RBFPDs debonded and the debonding rate was 4%. Nine patients had abutment dentin sensitivity after restoration (14%) with a mean duration of 6.3 months.
Conclusions:
The pin-ledge retention form could increase the short-term survival rate of the RBFPD obviously and obtain favorable clinical effects.
