Abstract:
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.
