摘　　要：目的观察嵌体间接粘接与树脂直接粘接对根管治疗牙抗折能力的影响。方法将80例接受根管治疗的患者随机分为对照组(40例,接受树脂直接粘接修复)与观察组(40例,接受嵌体间接粘接修复)。以电子万能实验机检测离体牙抗折能力及折裂形式,比较2组临床治疗效果。结果2组离体牙发生牙折时,破坏载荷最小值、最大值、平均破坏载荷比较,观察组均高于对照组(P<0.05)。观察组20例接受牙折试验牙中,可修复折裂占95.000%,高于对照组的55.00%(P<0.05)。观察组总有效率高于对照组(P<0.05)。结论根管治疗后接受嵌体间接粘接,可提高牙齿抗折能力及治疗效果,适于在临床推广应用。Objective To observe the effect of indirect inlay bonding and resin direct bonding on the anti-flexibility of the root canal treatment.Methods 80 patients receiving root canal treatment were randomly divided into control group(40 cases,received resin direct bonding repair treatment)and observation group(40 cases,received inlay indirect bonding repair treatment).The electronic universal testing machine was used to detect the fracture resistance and fracture forms of the isolated teeth,and the clinical treatment effects of the two groups were compared.Results The minimum,maximum,and average failure loads of the observation group was higher than the control group(P<0.05)when the two groups of isolated teeth fractured,.Among the 20 patients in the observation group who underwent dental fracture test,95.000%of the teeth were repairable,which was higher than that of the control group(55.00%)(P<0.05).The total clinical effective rates of the two groups were 97.50%and 77.50%,respectively.The total effective rate of the observation group was higher than the control group(P<0.05).Conclusion Indirect inlay bonding after root canal treatment can improve tooth flexural resistance and improve clinical treatment effect,which is suitable for clinical application.
