Abstract:

Objective　To evaluate the masticatory efficiency of implant supported dentures in partially edentulous patients and the patients′satisfaction onmasticatory function.Methods　The masticatory efficiency of implant supported dentures of 22 patients were tested. The questionnaire of the patients′satisfaction about masticatory function had also been collected. The correlativity of the masticatory efficiency of implant supported dentures and the scores evaluated by patients onmasticatory functionwere analyzed. Results　There were no differences in masticatory efficiency between implant supported denture and non-implant supported den- ture (natural teeth and porcelain-fused-to-metal fixed bridges). The patients gave high scores to the satisfaction about masticatory function in the questionnaire. But the test results of masticatory efficiency were not related with the scores evaluated by patients. Conclusion　The implant supported denture could meet the requirement of normal masticatory function. The patients were sati- sfactory with the masticatory function of implant supported dentures, but the patients′subjective evaluation about masticatory func- tion was probably influenced by varied factors.
