摘要/Abstract

摘要： 目的评价椅旁CAD/CAM系统（CEREC ACTM）进行全瓷修复的临床效果。方法针对619例患者的667颗各类牙体缺损患牙采用西诺德的瓷睿刻系统（CEREC ACTM）进行临床即刻椅旁CAD/CAM全瓷修复，1年后对597例患者的603颗瓷睿刻修复体进行临床效果评价。采用USPHS修订版指标检查，包括美观——解剖形态、颜色匹配、边缘变色、表面质地；功能——边缘吻合性、磨耗（邻接、动静态咬合关系）；生物学性能——牙髓活力、继发龋。结果 1年的随访结果发现，临床存留率达到95.11%，失败病例中修复体折裂占比为83%。93%的全瓷修复体表现出较高的美学评分，82%的修复体保持了较好的功能评分，而100%的修复体未见生物学并发症。结论不同牙体缺损患牙的瓷睿刻椅旁CAD/CAM全瓷修复，可获得理想的临床效果，但仍需长期随访。

Abstract: Objective To evaluate the clinical effects of all-ceramic restoration with chairside CAD/CAM system (CEREC ACTM). Methods A total of 667 large CEREC ACTM single-tooth all-ceramic restorations were fabricated to restore different tooth defection in 619 patients. After 1 year 603 teeth from 597 patients were reevaluated according to modified USPHS criteria regarding aesthetic properties, e.g., “anatomic form”, “color match”, “marginal discoloration” and “surface roughness”; functional properties, e.g., “marginal integrity”, wear include “proximal contact” and “static/dynamic occlusal relationship”; and biological properties, e.g., “tooth vitality” and “secondary caries”. Results The clinical follow-up showed that survival rate was 95.11% in our study. In these failure cases, bulk fracture of all-ceramic restorations still accounted for well up 83% of the total. 93% of the restorations revealed sufficient ratings for esthetic properties. 82% of the restorations maintained favorable ratings for functional properties. No biological complications, for example, caries, hypersensitivity, were observed. Conclusion The sufficient rating of modified USPHS criteria demonstrates that all-ceramic chairside CAD/CAM (CEREC ACTM) generated restorations in clinical performance are favorable. Therefore, long-term follow-up studies are needed to assess the clinical effects of all-ceramic restorations with chairside CAD/CAM system.
