摘　　要：目的 分析比较IPS.e.max和Lava^(TM)Ultimate制作髓腔固位冠修复短冠磨牙牙体缺损的临床疗效。方法 选取2018年2月至2019年12月到首都医科大学大兴教学医院口腔科治疗短冠磨牙牙体缺损患者72例,102颗患牙作为研究对象,采用随机数表法将患者分为IPS.e.max髓腔固位冠组(A组)和Lava^(TM)Ultimate髓腔固位冠组(B组),采用双色印模法获取修复体与基牙之间间隙的硅橡胶薄膜,测量9个点位间隙大小;参照改良美国公众健康服务标准,分别在修复后3、6和12个月对两组修复效果进行评价并对两组患者修复后12个月牙周情况进行比较。结果 两组修复体与基牙之间间隙各个点位比较,差异无统计学意义(P> 0.05)。修复后3、6个月两组修复体边缘染色A级率比较,差异无统计学意义(P> 0.05),修复后12个月边缘染色A级率比较,差异有统计学意义(P <0.05);其他指标A级率修复后3、6及12个月两组修复体差异无统计学意义(P> 0.05)。两组患者修复前及修复后12个月牙周探诊深度(PD)、龈沟出血指数(SBI)及牙龈指数(GI)比较,差异无统计学意义(P> 0.05)。结论 采用IPS.e.max与Lava^(TM)Ultimate制作髓腔固位冠修复短冠磨牙牙体缺损均取得理想的效果。Objective To analyze and compare the clinical efficacy of IPS.e.max and Lava^(TM) Ultimate in repairing the dental defect of short coronal molars with endocrown.Methods A total of 72 patients with the dental defect of short coronal molars admitted to the Department of Stomatology in Daxing Teaching Hospital of Capital Medical University from February 2018 to December 2019 were selected,with 102 diseased teeth taken as the study objects.They were divided into the IPS.e.max endocrown group(Group A)and the Lava^(TM) Ultimate endocrown group(Group B)using the random number table method.The silicone rubber membrane of the gap between the restoration and the abutment was obtained by bi-color silicone rubber impression technique,and the gap size of 9 points was measured.According to the modified American standards for public health service,the repair effects of the two groups were evaluated at 3,6 and 12 months after repairing,and the periodontal conditions of the two groups were compared at 12 months after repairing.Results There was no significant difference between the two groups in the gap between the restoration and the abutment(P>0.05).There was no significant difference in Grade A marginal staining at 3 and 6 months after repairing(P>0.05),but significant difference in Grade A marginal staining at 12 months after repairing(P<0.05).There were no significant differences in the Grade A rates of other indexes between the two groups at 3,6 and 12 months after repairing(P>0.05),and no significant differences in probing depth(PD),sulcular bleeding index(SBI)and gingival index(GI)before repairing and 12 months after repairing(P>0.05).Conclusion Ideal effects are achieved for IPS.e.max and Lava^(TM) Ultimate in repairing the dental defect of short coronal molars with endocrown.
