Evaluation of reconstructing extensively damaged short crown molar by golden alloy post inlay

目的:评价利用贵金属合金带桩嵌体修复短冠牙体缺损的效果。方法:对146颗后牙残冠经完善根管治疗后,制作贵金属合金带桩嵌体,修复完成后,每年复查1次。结果:经过1～4年的随访观察,144颗患牙经过修复治疗后获得满意效果,1例出现修复体边缘密合不良及继发龋、1例出现食物嵌塞。结论:利用贵金属合金带桩嵌体修复短冠牙体缺损,是一种效果良好的修复方法。

Objective： To evaluate the effects repairing extensively damaged short crown molar with golden alloy post inlay. Methods： After being treated with root canal therapy, 146 extensively damaged short molar crowns were reconstructed by golden alloy post inlays. All caseswere reguired to recheck once a year. Results： According to a period of 1 to 4 years follow-up, 144 out of 146 restored crown molars were well repaired except one failure due to secondary dental caries and ill-fitting marginal adaptation, and one failure with food impaetion. Conclusion： Extensively damaged short crown of molars can be well reconstructed by golden alloy post inlays.
