固定义齿修复后食物嵌塞的原因分析及扩隙树脂修复治疗

摘要

ObjectiveTo discuss the cause of food impaction after fixed denture restoration and to analyze the therapeutic effect of gap expansion and resin repair.Methods A total of 100 patients who suffered from food impaction after they received fixed partial denture were chosen. The cause of food impaction was analyzed. Treatment methods were applied on the basis of different causes. Gap expansion and resin repair were implemented to remove food impaction caused by the poor contact of the denture with healthy adjacent teeth.Results The poor contact between fixed denture and healthy adjacent teeth was the major cause of food impaction (70%) . The effective rate of treatment among patients who received fixed partial denture but suffered from food impaction after 3 years was 100%.Conclusion The proposed method can be applied to treat food impaction caused by the poor contact of denture with healthy adjacent teeth.%目的：探讨固定义齿修复后食物嵌塞的原因，并对保留固定义齿扩隙树脂修复治疗的效果进行分析。方法选择100例固定义齿修复后出现食物嵌塞的病例，分析食物嵌塞的原因并采取相应的处理方法，对由于与健康邻牙接触不良而导致食物嵌塞者，采用保留固定义齿扩隙树脂修复法进行治疗。结果固定义齿与健康邻牙间接触不良是食物嵌塞的主要原因（70%）。随访3年，100例固定义齿修复后食物嵌塞患者的治疗有效率为100%。结论扩隙树脂修复法是固定义齿与健康邻牙接触不良的一种有效治疗方法。
