1 of 6A tooth that already had a root canal still has trouble at the very tip of its root

A tooth that already had a root canal still has trouble at the very tip of its root
Numbed. Nothing is done through the top of the tooth this time
A small opening is made in the gum and bone beside the root tip
The very tip of the root is removed
The end is sealed from the outside and a stitch or two closes the gum
Bone quietly fills back in over the following months

通常由谁来做

牙髓病医生. 转诊给牙髓病医生或口腔外科医生。

一个值得问的问题

这是再次治疗失败后的下一步，还是替代再次治疗的方案？

根管治疗主要类D3431

D3431. 添加一种生物凝胶帮助组织愈合。

当根管治疗无法解决牙根尖端的问题时，外科医生会打开牙龈，去除牙根尖端并从外部封闭。相关代码包括在该手术中同时植骨、只去除磨牙的一个牙根，以及把牙齿重新植回原位。

牙齿旁边的牙龈被掀起，去除牙根末端几毫米以及周围发炎的组织，切口从外部密封后再把牙龈缝合回去。相关代码涵盖在同一次手术中加做植骨、去除磨牙的一个牙根并保留其余部分，以及在牙齿取出后把它放回原位。大多数保险计划把这归为主要类。实际能报销多少因计划而异。
