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。
Objective To evaluate the clinical effects of all-ceramic restoration with chairside CAD/CAM system（CEREC AC^TM）.Methods A total of 667 large CEREC AC^TMsingle-tooth all-ceramic restorations were fabricated to restore different tooth defection in619 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 AC^TM） 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.
