摘要

背景:严重的强直是罕见的，任何受影响的牙齿都不太可能自发脱落。如果不及时治疗，可能会出现后续并发症。我们治疗了一个10岁的男孩，他的牙齿长期受到强直的影响，导致下颌第二前磨牙脱位。由于邻牙倾斜，拔牙空间不足，需进行补位治疗。结论发现强直牙时应正确判断其严重程度，并选择适当的时机进行治疗。

Severe dislocation of mandibular second premolar associated with deep ankylosis of primary molar

Background

Severe ankylosis is rare and any affected teeth are unlikely to exfoliate spontaneously. If left untreated, subsequent complications can develop.

Case presentation

We treated a boy aged 10 years with a tooth affected by ankylosis for a long period, which caused dislocation of the mandibular second premolar. Because adjacent teeth were inclined, there was insufficient space for extraction and space regaining therapy was required.
