目的观察二次扫描在制作计算机辅助设计与辅助制作(CAD-CAM)氧化锆全瓷冠中的临床效果,并对比不同扫描系统在此过程中的可操作性,以期为临床提供参考.方法应用二次扫描完成氧化锆全瓷冠40件,其中Proeera全瓷冠10件(使用接触式扫描仪),Everest全瓷冠30件(使用光学扫描仪).利用二次扫描制作不同形态的基底冠.修复后1 d、3、6、12、24个月进行临床检查,内容包括边缘适合性、颜色、固位、折断或破损情况.结果 40件全瓷冠随访6～24个月,平均12个月.临床检查中40件全瓷冠的各项检查结果均为满意.结论二次扫描可以完成复杂形态的CADCAM氧化锆基底冠的制作,保证氧化锆全瓷冠饰瓷厚度均匀适度.应用二次扫描时,光学扫描仪相比接触式扫描仪更适合于完成复杂形态的氧化锆基底冠.

Objective To introduce the double scanning for producing computer aided design and computer aided manufacture (CAD-CAM) zirconia crowns,and to compare Procera with Everest CAD-CAM system by observing clinical effects of the crowns.Methods Forty CAD-CAM zirconia crowns (10 crowns by Procera,and 30 crowns by Everest) were evaluated,and the examination criteria included:marginal fit,aesthetics,gingival health,retention,and fracture.All of the zirconia copings were produced using double scanning.Procera system and Everest system use contact scanner and optical scanner respectively. Results The observation time for the crowns ranged from 6 to 24 months.The resulm of clinic evaluation were acceptable in all restorations.Conclusions Double scanning could be used to produce complicated zirconia copings by CAD-CAM in order to get proper symmetrical porcelain length.It Wag easier to make complicated coping with contact scanuer than with optical scanner.
