Three-dimensional assessment of root migration and rotation patterns after coronectomy

在前面的一篇文章中(《Treatment methods for lower third molar with a high possibility of causing injury to inferior alveolar nerve》)提到了通过Coronectomy technique来处理牙根紧邻下牙槽神经的阻生第三磨牙。

近期北大口腔在一项临床试验中对冠切术后牙根移动情况以及影响骨质覆盖的因素进行了分析1

虽然对于国内临床试验的数据真实性个人仍然是持审慎态度,但是不妨作为参考。

总体上来讲,对于牙根紧邻下牙槽神经的情况,冠切术是一项成本低、术后反应轻且近远期效果都可以接受的处理方法,但是需要严格按照规范进行操作,以尽量减少术后出现感染等并发症的机率。
