目的:探讨牙齿折裂后全冠修复的远期临床疗效。方法:将我院2007年6月至2009年10月接诊的磨牙折裂的患者经根管治疗后全冠修复共137例进行分析,根据不同的影响因素统计1-4年的恢复情况和成功率。并对分组因素进行检验。结果:4年的成功率均在60%以上多数在80%,说明全冠修复在治疗牙齿折裂中取得了较好的临床效果。对于术后1、2、3、4年进行组间分析,术后4年的成功率明显下降。对于按照年龄,性别牙位进行统计学检验,各个影响因素对于术后的成功率没有明显的影响。即,男女,年龄,牙位不同,可以认为,其成功率基本一致。结论:全冠修复在治疗牙齿折裂中取得了较好的临床效果。可以最大程度的保留患牙。
Objective: To investigate the long-term clinical efficacy of crown restoration after tooth fracture.

For statistical test according to age and gender, there is no obvious influence on the success rate after operation. That is, men and women, age, different teeth, can be considered, the success rate is basically the same.
