| 摘 要： | 目的 观察CEREC inLab计算机辅助设计和制造（CAD/CAM）的氧化锆全瓷冠修复复杂后牙的临床效果。方法 对于242名需行单个后牙冠修复的患者，采用CEREC inLab CAD/CAM设计制作二氧化锆全瓷修复体，共242件。分别在粘接完成时、6个月、12个月、24个月和36个月进行临床观察，采用改良的美国公共卫生署标准评估。结果采用χ2检验分析。结果 观察期间有5名患者失访，对于剩余修复体观察发现，随着时间推移，修复体的成功率下降，在36个月时A级成功率在85%以上。结论 CEREC inLab制作的单个后牙的二氧化锆全瓷修复体，短期成功率良好。

| Abstract: | Objective To observe and evaluate the clinical performance of zirconia crowns made by CEREC inLab com-puter aided design/computer aided manufacturing(CAD/CAM) for posterior teeth. Methods A total of 242 patients were implanted with zirconia crowns fabricated by CEREC inLab CAD/CAM. The crowns were evaluated by Modified US Public Health Service criteria at baseline, 6, 12, 24, and 36 months. The chi-square test was used to analyze the survival rate. Results All but five crowns were evaluated by an independent evaluator at baseline, 6, 12, 24, and 36 months. The survival rate de-clined with time. The A score percentage was above 85% at 36 months. Conclusion The single zirconia crowns fabricated by CEREC inLab CAD/CAM demonstrate satisfactory clinical performance during a short period. |
