Abstract: Objective To explore a fabricating method of incisor all-ceramic cantilevered resinbonded fixed partial denture(RBFPD)and evaluate their clinical performances.Methods All-ceramic cantilevered RBFPDs were made to replace 1 missing incisor in each of 10 patients.The RBFPDs with lingual surface retainer were made of Empress Ⅱ ceramic materials and luted with resin cement.The prostheses were examined at 2 weeks,1 year and 2 years after denture insertion.Examining criteria included:fracture of bridge,marginal adaptation,secondary caries,and color match.Results The average follow-up period was 14.7 months.No framework fracture and retainer debonding were observed and margihal adaptation was evaluated as good.Seven RBFPDs matched the color of adjacent teeth,and other three did not match well but within the acceptable range of tooth shade difference.Conclusions The results of this preliminary study suggest that the clinical performances of all-ceramic cantilevered RBFPDs are good in short-term evaluation,but their long-term success needs to be further investigated.
