三种不同修复方式修复根管治疗后前磨牙牙体缺损的临床研究

目的 探讨三种不同修复方式修复根管治疗后前磨牙牙体缺损的临床效果。方法 选取南安市第二医院口腔科2014年6月至2015年8月收治的符合纳入条件的83例行前磨牙根管治疗的患者(共计90颗患牙)进行研究,随机分为高嵌体修复组、全冠修复组、桩核冠修复组,每组各30 颗患牙。在修复后1年、2年、3年复诊,比较三种不同修复方式的修复效果。结果 高嵌体修复组、全冠修复组、桩核冠修复组在三年观察期结束时的修复优秀率分别为:92.9%、82.1%、85.2%;成功率分别为96.4%、92.9%、96.3%。各组的修复优秀率、成功率在各时间段比较差异均无统计学意义(P＞0.05)。结论 高嵌体、全冠、桩核冠用于根管治疗后前磨牙牙体缺损的修复均能取得较好的修复效果;高嵌体牙体预备量相对较少,能更多保留牙体组织,推荐使用。

Clinical effect of three different restoration methods for restorationof premolar defect after root canal therapy

Objective To investigate the clinical effects of three different restoration Methods on the restoration of premolar defect after root canal therapy.Methods 83 patients (90 teeth) with premolar root canal therapy were selected from the Department of Stomatology,Second Hospital of Nan′an City from June 2014 to August 2015.They were randomly divided into high inlay group,full crown group and post-core crown group with 30 teeth in each group.One year,two years and three years after repair,the effects of three different repair methods were compared.Results At the end of the three-year observation period,the excellent rates of inlay restoration,full crown restoration and post-core crown restoration were 92.9%,82.1% and 85.2%,respectively,and the success rates were 96.4%,92.9% and 96.3%,respectively.There was no significant difference in the excellent rate and success rate of each group in each time period (P＞0.05).Conclusion High inlay,full crown and post-core crown can achieve good results in the restoration of premolar defects after root canal therapy.High inlay teeth have relatively less preparation and can retain more dental tissues and recommended for use.
