【摘要】 目的总结诊断性蜡型在CAD/CAM前牙美容性修复中的运用。方法临床选择110例患者共137例全瓷冠,术前制作诊断性蜡型与患者进行沟通,医患双方达成一致后,通过Sirona inEos计算机印模采集系统获取诊断蜡型的三维数据,将其与基牙模型数据拟合,基于inLab V3.80软件的回削程序设计并制作精确的氧化锆内冠,采用Vita公司VM9饰瓷完成最终修复体。结果经一年半的随访观察,所有氧化锆全瓷冠临床检查边缘密合,未出现崩瓷或折裂现象,患者对修复体的外形与颜色满意。结论运用诊断性蜡型技术方便医患间就美观问题进行主观交流,运用CAD/CAM回削技术制作的全瓷冠内冠可以为饰瓷预留合理空间,有助于提高氧化锆全瓷修复体的质量。更多还原

【Abstract】 Objective To sum up the clinical application of diagnostic wax-up in the esthetic anterior teeth restorations with CAD/CAM all ceramic restorations.Methods 110 patients with 137 all-ceramic crowns were clinically enrolled in this study.First,dianostic wax-up used in the esthetic anterior teeth restorations to help dentists communicate with patients;secondly,the shapes of wax frameworks and abutment teeth were captured and digitized by Sirona inEos system,and each individually shaped framework to grant a precise zirconia coping was created based on the reduced program of inLab V3.80 software.All restorations were veneered with VITA VM9.Results During the 18 months′ follow-up visit,none of the all-ceramic zirconia restorations had to be replaced due to framework fracture or unrestorable delamination of the ceramic veneer,the marginal fitness of restoration was quite well,and the shape and colour of all restorations satisfied the patients.Conclusions Based on the results of this study,it can be concluded that,diagnostic wax-up is useful in helping dentists communicate with patients;all-ceramic crowns made by CAD/CAM reduced program can make proper room for veneering ceramic,which is helpful to improve the quality of all-ceramic zirconia restorations.更多还原
