Abstract
Objective To explore the long-term effect of all porcelain onlays in the repair of pregrinding tooth defects and its influence on masticatory function.Methods A total of 120 patients who received premolar dental defect repair in the hospital from June 2018 to June 2019 were selected,according to random number table method,they were divided into control group(n=60)and study group(n=60)according to treatment methods.The control group was treated with all-ceramic crowns,and the research group was treated with all-ceramic high inlays.The masticatory function,gingival index,long-term effect,repair satisfaction and complications of the two groups were compared.Results After treatment,the total effective rate of the study group was 93.33%,which was higher than that of the control group(76.67%)(P＜0.05).After treatment,the masticatory function of the study group was higher than that of the control group,and the gingival index was lower than that of the control group(P＜0.05).The repair satisfaction of the study group was 91.67%,which was higher than that of the control group(75.00%)(P＜0.05).The complication rate of the study group was 5.00%,which was lower than that of the control group(16.67%)(P＜0.05).Conclusion All-ceramic onlay restoration has better long-term effect than all-ceramic crown restoration on premolar teeth defect,which is conducive to improving masticatory function,maintaining gingival health,reducing the incidence of complications,and higher patient satisfaction.关键词
