摘　　要：目的:观察二氧化锆髓腔固位冠在短冠磨牙保存修复中的临床效果。方法:选择134颗短冠磨牙,先经根管治疗及龈上洁治术,1～2周后预备剩余牙冠以及髓腔,硅橡胶印模、灌模,经过计算机辅助设计(Computer Aided Design,CAD)和计算机辅助制作技术(Computer Aided Manufacturing,CAM)制备出二氧化锆髓腔固位冠,树脂粘结剂粘固,并于6个月、1年后复查。结果:132颗髓腔固位冠无松动,边缘密合,可发挥正常咀嚼功能,美观效果良好,牙龈无明显红肿,只有两颗牙齿修复失败。结论:二氧化锆髓腔固位冠用于短冠磨牙修复可取得良好的效果,是一种很好的修复选择。Objective To evaluate the clinical effect of zirconia endocrowns being used in preserving endodontically treated short crown molars. Methods One hundred and thirty-four endodontically treated molars were selected from 50 patients in this study.All the short crown molars had been endodontically treated and performed with ultrasonic scaling. After 1-2 weeks, the crowns and pulp chambers were prepared. The impressions and master casts were gained and zirconia endocrowns were fabricated with computer aided design and computer aided manufacturing.The zirconia endocrowns were cemented with resin cement.The further consultations were offered to these molars after 6 months and 1 year. Results In these cases, one hundred and thirty-two teeth of them were doing function well without exhibiting mobility.which presents good results in marginal fitness, satisfaction for beauty,and prevalence of gingivitis.Just two of them doing defeated. Conclusion Zirconia endocrowns is preferable to preserve endodonctically treated molars,which is a good choice for those short coronal molars.
