摘要/Abstract

摘要： 目的评价二硅酸锂玻璃陶瓷在前牙过小牙修复中的临床应用。方法对45例患者的87颗牙使用IPS e.max Press铸瓷贴面修复，于修复完成后1、6、12、24、36个月进行复查，参见改良加利福尼亚牙科协会（CDA）/Ryge标准进行评价，检查包括边缘适合性，瓷表面质地，颜色匹配，牙敏感症状和牙龈健康情况五个方面。结果 1个月复查时，11颗基牙出现牙敏感症状，予脱敏治疗处理后症状明显改善。6个月复查牙龈情况，9颗基牙出现牙龈炎症，经卫生宣教及系统牙周治疗后症状好转。1个月及6个月复查时，所有贴面边缘密合，完整性好，瓷表面质地良好。12个月复查时出现1颗贴面完整脱落，清洁处理后重新粘固未再次发生脱落。24个月复查时，一患者进食过程中前牙误咬硬物发生修复体崩折，牙本质暴露，予重新制作贴面进行修复。观察到36个月时7颗基牙出现不同程度龈退缩。结论二硅酸锂玻璃陶瓷贴面适用于前牙区过小牙修复，可获得良好的临床效果和远期预后。

Abstract: Objective To evaluate the clinical application of lithium disilicate glassceramic in the treatment of small anterior teeth restoration. Methods 87 teeth of 45 patients were restored by IPS e.max press ceramic veneers. The teeth underwent a detailed clinical examination according to the modified California Dental Association (CDA)/Ryge standards including marginal fitness, ceramic surface, color match, sensitivity, gingival health after 1 month, 6 months, 12 months, 24 months and 36 months. Results 11 teeth showed the sensitive symptoms at the review after 1 month and the symptoms were significantly improved after treatment. After 6 months, 9 teeth showed the inflammation of gums and the symptoms were improved after health education and periodontal treatment. Review after 1 month and 6 months showed that all the veneers had good marginal fitness, integrity and ceramic surface. Review after 12 months showed that a veneer fell off, and was reattached to the tooth surface after cleansing. Review after 24 months showed that a veneer collapsed during eating, and the dentin was exposed. The veneer was remanufactured and restored. Only 7 teeth showed obvious gingival retraction at the review after 36 months. Conclusion Lithium disilicate glassceramic veneer is suitable for the treatment of anterior teeth and can achieve good clinical effect and longterm prognosis.
