年轻恒牙外伤后残根深埋治疗的修复学评价

Prosthetics evaluate the treatment of burying residual teeth root of young permanent teeth after trauma

目的:研究因年轻恒牙外伤后深埋其残根保留牙槽骨骨量,与传统拔除残根相比,为后期修复是否带来更好的效果。方法:选择秦皇岛市第二医院2001年1月～2009年9月口腔科收治的年轻恒牙外伤患者60例,共计90颗患牙。将其随机分为实验组和对照组,实验组病例(共计50颗患牙)深埋保留残根,临时修复,待牙根形成后,行完善的根管治疗桩冠修复,或拔出残根后固定修复;对照组病例(共计40颗患牙)拔除残根后临时义齿修复,成年后固定义齿修复。结果:实验组50颗患牙中有45颗修复成功,成功率为90.0%;对照组的40颗患牙中有33颗修复成功,成功率为82.5%,两种方法修复成功率有着明显的统计学差异(P<0.05)。结论:年轻恒牙深埋残根有利于牙槽骨及颌骨发育,为将来修复提供了良好基础,其效果明显好于传统拔除方法。

Objective To research whether the post-repair result of burying residual teeth root is better than that of traditional extract it after young permanent teeth trauma. Methods The study was performed at the Second Hospital of Qinhuangdao with a target sample size of 60 young patients with a total of 90 young permanent teeth trauma,during January 2001-September 2009.AII patients were randomly divided into experimental group and control group.The experimental group contains 50 impaired teeth that residual teeth root were buried till the root formatted and then executed root canal treatment and dowel crown repair or pull out the root and fix it.The control group contains 40 impaired teeth which were pulled out at once and dentures were used to repair it after adult. Results In experimental group 45 of the 50 teeth were repaired successfully while 33 of the 40 teeth in control group.There is a significant difference between the two groups in repair ratio （P〈0.05）. Conclusion The method of burying residual teeth root is beneficial to the development of alveolar bone and jaw and provides a good basis for future repair,and the effect is obvious better than that of traditional method.
