摘　　要：目的：评价IPS e.max Press铸瓷髓腔固位冠修复经根管治疗的后牙牙体缺损的效果。方法：选择由牙体牙髓专业一年级研究生完成的铸瓷髓腔固位冠修复病例26例,均为行完善根管治疗后的后牙,18~24个月后回访检查。参考美国公共健康服务（USPHS）标准,对患牙继发龋、牙龈炎、牙折、修复体边缘完整性、边缘染色、修复体折裂/脱落情况进行评估。结果：26例病例中,1例修复体折裂,2例边缘完整性轻度受损,1例咬合面轻度缺损,其余未发现明显修复体的缺陷或因修复体引起的牙体、牙周等问题。结论：铸瓷髓腔固位冠修复根管治疗后的后牙牙体缺损可以取得满意的效果。Objective： To evaluate the clinical effect of IPS e. max press ceramic endocrown restoring posterior teeth after root canal therapy. Methods： Twenty--six posterior teeth after root canal therapy were restored by endo- dontic first--year graduate students with IPS e. max Press ceramic endocrown. The patients were recalled 18--24 months after the restoration and the restorations were assessed using the modified USPHS criteria including second- ary caries, gingivitis, tooth fracture, marginal discoloration, marginal integrity criteria, and restoration fracture/ dehond. Results： Of all the 26 teeth, one restoration was found broken. Two restorations had slight damage of mar- ginal integrity and one had slight damage of oeclusal surface. Other defects of endocrowns, or tooth and gingiva problems caused by the restorations were not found. Conclusion： Endocrown is an effective method of restoring pos- terior tooth after root canal therapy.
