| ［摘要］ 目的 了解楔状缺损较为合适的充填方法及调（牙合）对楔状缺损充填效果的影响。方法 将120颗上颌双尖牙随机分为三组，每组40颗，分别用光固化复合树脂直接充填、制备倒凹固位后充填、制备倒凹固位后充填并调（牙合）,观察2年以后的成功率。结果 制备倒凹加调（牙合）组的成功率为95.0%，制备倒凹组成功率为80.0%，而直接充填组成功率只有75.0%。制备倒凹加调（牙合）组高于其它两组，且差异有统计学显著意义（P<0.05）。结论 楔状缺损固位不佳者应先制备倒凹固位后再用光固化树脂充填，并适当调（牙合），会达到更好的临床效果。 |

| Abstract: |
| ［Abstract］ Objective To explore the feasible methods of filling and the effect of occlusal adjustment on the filling of wedge-shaped defect.Methods One hundred and twenty upper jaw double tines that were randomly divided into 3 groups,40 teeth in each group, were filled with light solidification compound resin directly, after making undercut retention and after making undercut retention and occlusal adjustment.The success rate was calculated.Results The success rates of the direct filling group, the undercut group, and the undercut and occlusal adjustment group were 75.0%,80.0% and 92.50% respectively.The success rate of the undercut and occlusal adjustment group was highest in 3 groups and different from those of the other groups obviously（P<0.05）.Conclusion The better clinical effect can be obtained if those teeth are treated by undercut retention, filling of the light solidification compound resin and occlusal adjustment. |
