摘　　要：目的评估全瓷髓腔固位冠对根管治疗后磨牙缺损的修复效果。方法我院行根管治疗患者78例(128颗磨牙),经完善根管治疗后,采用全瓷髓腔固位冠进行修复,于修复后2周、3个月、6个月、1年、2年进行随访,评价修复效果。结果 76例患者(126例修复体)完成全程随访,并纳入临床效果的评价中。随访期间,5例修复体发生脱落,修复体成功率为96.0%;修复体的外形、颜色、边缘适合性和龋损指标均在临床可接受范围内。修复早期(2周)牙龈炎发生率较高(17/13.5%),经对症治疗后均好转。结论全瓷髓腔固位冠对根管治疗后的磨牙缺损具有很好的修复效果。Objective To evaluate the clinical effect of ceramic endocrowns in repairing defecteive molars resulting from endodontic treatment. Method One hundred and twenty-eight molars in 78 patients were subjected to a treatment with ceramic endocrowns subsequent to endodontic treatment. The clinical effect was evaluated at 2 weeks,3 months,6 months,1 year and 2 years after treatment,respectively. Findings One hundred and twenty-six endocrowns in 76 patients completed the 2-year follow-up. 121 endocrowns were found to work well without exhibiting mobility,excepting 5 endocrowns,yielding a success rate of 96. 0%. The shape,color,marginal fitness and caries were maintained very well. There is a high incidence of gingivitis（ 17 /13. 5%） in early stage of recovery（ 2 weeks after treatment）,which recovered very well after symptomatic treatment. Conclusion Ceramic endocrown is effective in preserving the defective molars resulting from endodontic treatment.
