摘　　要：目的:探讨根面不同处理方法对覆盖基牙继发龋的影响。方法:应用2种不同方法处理基牙根面,行覆盖义齿修复牙列缺损。结果:自2002年以来以223个已完成根管治疗的牙作为基牙,对53例患者进行覆盖义齿修复,1年后随访,富士Ⅱ型玻璃离子水门汀临床疗效略高于金属顶盖;5年后随访,金属顶盖疗效高于富士Ⅱ型玻璃离子水门汀。结论:采用覆盖义齿修复牙列缺损是一种有效的保留患者牙槽骨的方法,采取金属顶盖处理基牙根面长期临床效果较佳,但要预防基牙继发龋以提高修复成功率。Objective： To investigate different treatment methods on the root surface abutment secondary caries effect of success rate of overdenture. Methods： We deal abutment root surface with two different methods and dentition defect of all patients were treated with overdentures. Results： 223 teeth with excellent root canal therapy have been selected as abutment since 2002. 53 patients were treated with overdentures. 1-year follow-up study showed that the clinical effect of GC Fuji Ⅱ was better than metal coping, and during a 5-year follow-up study, the result was the opposite. Conclusions： Dentition defect with overdentures is an effective method to keep patients＇ alveolar bone, and dealing abutment root surface with metal coping has long-term effect, but we have to prevent secondary caries of abutment in order to increase the success rate of repair.
