摘　　要：目的探讨二硅酸锂基玻璃陶瓷单端树脂粘接桥修复个别前牙缺失的临床效果,为个别前牙缺失修复方式的选择提供参考。方法本研究已通过单位伦理委员会审查批准,并获得患者知情同意。选取42例单颌前牙缺失数量在两颗内的患者,采用二硅酸锂基玻璃陶瓷单端树脂粘接桥修复,修复后6个月、1年、2年、3年进行随访,评价美学、功能修复效果及牙周健康状况,并采用视觉模拟评分量表(VAS)调查患者的满意度。结果观察期间,42例二硅酸锂基玻璃陶瓷单端树脂粘接桥修复的患者中有1例3个月内连接体发生断裂,1例2年内发生脱粘;美学修复效果的等级均评定为A级;修复后牙周健康状况良好,基牙及桥体下的软硬组织无临床吸收现象,评价指标均为A级;患者总满意率为100%。结论对于个别前牙缺失,二硅酸锂基玻璃陶瓷单端树脂粘接桥可达到微创、固位牢靠、美观舒适和生物相容性好的修复效果,患者满意度高,在临床中可以考虑作为一种理想的修复方式。Objective To investigate the clinical effect of lithium disilicate glass ceramic cantilever resin-bonded fixed partial dentures(CRBFPDs)on single anterior tooth loss to provide a reference for the selection of restoration methods for single anterior tooth loss.Methods This study was reviewed and approved by the Ethics Committee,and informed consent was obtained from the patients.Forty-two patients with less than two anterior teeth with monomaxillary loss were included in this study.After 6 months,1 year,2 years,and 3 years,the aesthetic and functional effects of the restorations and the periodontal health status were evaluated,and the visual analog scale(VAS)was used to assess pa-tient satisfaction.Results During the observation period,the connector fractured in one case within 3 months.One case had debonded within 2 years.The aesthetic restoration effect of all lithium disilicate glass ceramic CRBFPDs was categorized as Class A.The periodontal health was good,there was no clinical absorption in the soft and hard tissues of the abutment or subbridge,periodontal status according to the evaluation indices was classified as class A,and the total satisfaction rate of the patient was 100%.Conclusion For single anterior tooth loss patients,lithium disilicate glass ceramic cantilever resin-bonded fixed partial denture can achieve the restoration effect of less invasion,better adhesion,aesthetics,comfort and good biocompatibility.With high patient satisfaction,it can be considered an ideal restoration method for replacing a single anterior tooth.
