CEREC 3D系统制作全瓷修复体的临床研究

摘要

Objective:To observe clinical effect of all - ceramic dental restorations fabricated by CEREC 3D CAD/CAM system. Methods: Forty - one patients with 67 all - ceramic restorations were involved in this study. After one year, the clinical performance of the restoration was evaluated by the same dentist using modified USPHS criteria. Results; 86. 57% of all -ceramic restorations scored grade A by the modified USPHS criteria. The color matching of the restoration was satisfactory in 97. 01% patients with grade A by the criteria. Conclusion: The CEREC 3D CAD/CAM system could offer easy, accurate and quick fabrication of all -ceramic dental restorations with natural color.%目的:观察椅旁CAD/CAM系统CEREC 3D制作的各类全瓷修复体的临床应用效果.方法:选取41名患者,按照CAD/CAM系统CEREC 3D标准程序制作完成各类全瓷修复体67个.修复后追踪观察1年,由同一位医师按照改良的USPHS标准对修复体进行评价.结果:86.57％的全瓷修复体各项检查标准都达到了改良的USPHS标准的A类,颜色匹配方面最令人满意,达到A类标准者为97.01％.结论:CEREC 3D CAD/CAM系统能够便捷、精准、高效地制作具有天然牙色的全瓷修复体,临床效果令人满意.
