目的：探索数字化椅旁即刻全瓷修复系统的临床应用，设计并制作嵌体/高嵌体修复后牙牙体大面积缺损，对其临床修复效果进行评价及分析。方法采用Cerec AC系统结合IPS e.max CAD系列瓷块制作嵌体84个，高嵌体65个，共修复108例患者的149颗患牙，树脂水门汀粘结完成。修复后6个月由2位医师按照改良的美国公共卫生协会评价标准（USPHS）对修复体检查并进行疗效评价，对结果进行统计分析（α=0.05）。结果各指标中A级、B级病例数在即刻和6个月后的差异均无统计学意义（P>0.05），90%以上的修复体各项指标均达到A级，在解剖形态、边缘密合性、边缘着色、颜色匹配、固位、牙龈健康、继发龋等方面表现良好。结论计算机辅助设计/计算机辅助制作系统结合可切削玻璃陶瓷修复牙体严重缺损可取得良好的修复效果。数字化椅旁即刻全瓷修复技术是牙体大面积缺损的理想修复方法。

Objective To explore the clinical application of digital chair?side immediate all?ceramic restoration system,design and fabricate inlays and onlays to restore the large?defected molars,and to analyze and evaluate the efficacy of this clinical restoration. Methods Totally 84 inlays and 65 onlays were fabricated with IPS e.max CAD series ceramic blocks by using Cerec AC system to conduct immediate all?ceramic restorations of 149 teeth for 108 patients. The inlays and onlays were applied and cemented to the prepared teeth with dual?cured resin luting agent. The restored molars were re?examined by two dentists after six months. The analysis standard was based on the United States Public Health Service(USPHS criteria) and the results were statistically analyzed(α=0.05). Results There was no statistically significant difference in the case numbers of grade A and grade B for each index comparing the immediate condition to the condition after 6 months. Over 90 percent of ceramic inlays and onlays were quali?fied to be grade A. The restorations were well in the aspects of anatomic morphology,marginal integrity,color match,marginal discoloration,reten?tion,gingival health and secondary caries. Conclusion Computer aided design/computer aided manufacture(CAD/CAM)system combined with machinable glass ceramics can achieve a favorable result in restoration of large?defected teeth. Digital chair?side immediate all?ceramic restoration technique is an ideal solution for large?defected tooth restoration.
