摘　　要：目的探讨太极扣冠外附着体（ERA）在后牙游离缺失修复中的临床应用效果。方法随机选择22例后牙游离缺失患者,采用自身前后对照设计,在使用ERA义齿修复前先佩戴钢丝卡环胶托活动义齿,分别在佩戴钢丝卡环胶托活动义齿与ERA义齿当时戴牙（即刻）、戴牙后1个月进行咀嚼功能测试,随访6个月~2.5年,采用问卷调查的形式从患者主观感受和X线片两方面观察修复效果。结果 ERA义齿的咀嚼效率要高于钢丝卡环胶托义齿,且两者差异有统计学意义（P〈0.05）。在修复满意度调查中,两种义齿在语音和舒适度上无明显差别,但在外观、咀嚼效率、固位三个方面上,ERA义齿高于钢丝卡环胶托义齿,且两者差异有统计学意义（P〈0.05）。结论 ERA义齿修复后牙游离端缺失的总体临床效果优于钢丝卡环胶托义齿。Objective To study the clinical application of easy resilient attachment（ERA） in posterior teeth for extension defect. Methods A total of 22 patients with extension defect were selected randomly through a self-controlled clinical study. These patients were wearing removable partial dentures before using the ERA dentures. Chewing function tests were performed using the ERA dentures immediately and one month later. A follow-up period was scheduled from 6 months to 2.5 years. The satisfaction of patients with the dentures was measured by using questionnaires, and an X-ray inspection was conducted to determine the treatment results. Results The chewing efficiency of ERA dentures is higher than that of removable partial dentures when these dentures are worn immediately and a month later. The difference between the two dentures was significantly different（P〈0.05）. However, no significant difference was found in terms of pronunciation and comfort. The appearance and retention of ERA dentures are superior to those of removable partial dentures（P〈0.05）. Conclusion The effects of ERA dentures are significantly superior to those of removable partial dentures.
