【摘要】 目的:评价不同边缘形式的髓超嵌体修复根管治疗后磨牙的临床效果。方法:选取114颗根管治疗后磨牙进行髓超嵌体修复,分别设计成三种边缘形式:平面对接边缘组(41例)、直角边缘组(36例)和凹型边缘组(37例)。随访22个月,并对各组临床效果进行评价,比较3组修复体的成功率和存留率。结果:平面对接边缘组、直角边缘组、凹型边缘组的成功率分别为85.37%,80.56%,83.78%,存留率分别为100%、94.44%、97.30%,3组髓超嵌体的成功率和存留率相比较,差异均无统计学意义(P>0.05)。结论:3种边缘形式的髓超嵌体均能满足临床修复的要求,平面对接边缘组效果最佳,值得临床推广应用。更多还原

【Abstract】 Objective: The goal of this study was to evaluate the clinical effect of different marginal forms of endo-overlay in restoring molars after root canal therapy. Methods: A total of 114 teeth with root canal therapy were restored with endo-overlay, which were designed into three marginal forms: butt-joint edge group(n=41), right-angle edge group(n=36) and concave edge group(n=37). After 22 months follow-up, the clinical effect of each group was evaluated, and the success rate and survival rate of the three groups were compared. Results: The success rate of butt-joint edge group, right-angle edge group and concave edge group was 85.37%, 80.56% and 83.78% respectively,and the survival rate was 100%, 94.44% and 97.30% respectively. There was no significant difference in the success rate and survival rate among the three groups(P>0.05). Conclusion: The three types of marginal forms of endo-overlay can meet the requirements of clinical restoration, and the butt-joint edge group has the optimal effect, which is worth popularizing in clinical practice.更多还原
