单端全瓷树脂粘接桥在修复个别前牙缺失中的应用

Application of single-retainer all-ceramic resin-bonded fixed partial denture in replacing single anterior tooth

目的探讨单端全瓷树脂粘接桥在修复个别前牙缺失中的临床效果。方法选择20例个别前牙缺失患者进行单端全瓷树脂粘接桥修复,并进行2年随访,采用美国公共健康协会(APHA)制定的修复体临床评价标准进行临床疗效评价分析。结果 20例单端全瓷树脂粘接桥在修复完成后6个月,APHA的6项评价指标均达到A级;修复完成后1年,1例修复体周围龋为B级,其余均为A级;修复完成后2年,1例修复体周围龋为B级,1例修复体折断为B级,其余均为A级。结论对于个别前牙缺失,单端全瓷树脂粘接桥是可供临床选择的修复方式之一。

Objective In this study, we aimed to evaluate the clinical effect of single-retainer all-ceramic resin-bonded fixed partial denture （RBFPD） on the single anterior tooth loss patients. Methods A total of 20 single-retainer all-ceramic RBFPD were fabricated and evaluated in a two-year follow-up observation. The restorations were examined on the basis of the Ame- rican Public Health Association （APHA） criteria. Results A total of 20 single-retainer all-ceramic RBFPD achieved class A evaluation after a six-month follow-up observation. One single-retainer all-ceramic RBFPD was classified as class B for secondary caries after a one-year follow-up observation. After a two-year follow-up observation, one single-retainer all-ceramic RBFPD was classified as class B because of secondary caries, and one single-retainer all-ceramic RBFPD was classified as class B because of fxacture. Conclusion Single-retainer all-ceramic RBFPD is a promising and optional method in replacing single anterior tooth.
