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 investigate the clinical effect of extra-corollary attachment (ERA) in the repair of posterior free-detached defect. Methods Twenty-two cases of posterior free-loss patients were randomly selected. Before and after ERA denture repair, ERS denture was worn before wearing ERA denture and ERA denture. Immediately), 1 month after wearing the teeth to chew function test, followed up for 6 months to 2.5 years, the form of questionnaire from the patient’s subjective perception and X-ray film to observe both the repair effect. Results The masticatory efficiency of ERA denture was higher than that of plastic retaining ring, and the difference was statistically significant (P <0.05). There was no significant difference in speech and comfort between the two dentures in the satisfaction survey, but the ERA dentures were higher than those of the steel retaining ring in terms of appearance, chewing efficiency and retention, and the difference was Statistical significance (P <0.05). Conclusion The overall clinical effect of ERA denture in repairing the posterior free end of tooth is better than that of steel retaining ring.
