GI-II核型全瓷修复体的临床报道

Clinical evaluation of all-ceramic restorations(GI-II infiltrated ceramic core veneered Vitadur alpha veneeringporcelain)

目的:对GI-II核型全瓷修复体进行临床评价。方法: 使用修改的CDA标准从边缘完整性、解剖形态、表面光滑度、颜色匹配性四个方面对63个冠桥修复体进行评价。对24个修复体的菌斑指数,牙龈指数进行评价。结果:对23例患者的63个冠进行临床评价,可接受率为96.9%,满意率为89.9%。24个修复体与其对照牙相比,菌斑指数较低,牙龈指数无显著性差异。结论:本研究结果支持使用GI-II型渗透陶瓷为底层制作单冠,或前牙3单位桥的修复体。

Objective: To evaluate the new kind of all-ceramic restorations. Methods: In this study, we practiced thenew restoration in vivo, and evaluated those margin integrity, anatomic form, color and surface, wear, plaque and gingivalbleeding. Results: Of the 63 crowns examined in this study, 96.9% were rated as acceptable and 89.9% as satisfaction inaccordance to the changed CDA quality evaluating system. There was no statistically significant difference with regard toGI, while there was a reduced occurrence of plaque in connection with all-ceramic restoration surface. Conclusion: Thenew system can be used for the crowns or the anterior three-unit restorations.
