Paresthesia of the lower lip is uncommon during orthodontic treatment. In the present case, paresthesia occurred during orthodontic leveling of an extruded mandibular left second molar. It was decided to remove this tooth from the appliance and allow it to relapse. A reanatomization was then performed by grinding. The causes and treatment options of this rare disorder are reviewed and discussed. The main cause of paresthesia during orthodontic treatment may be associated with contact between the dental roots and inferior alveolar nerve, which may be well observed on tomography scans. Treatment usually involves tooth movement in the opposite direction of the cause of the disorder.
下唇感觉异常在正畸治疗期间并不常见。在本病例中，在下颌左侧第二磨牙伸长的正畸整平过程中出现了感觉异常。决定将该牙从矫治器中移除并任其复发。然后通过磨削进行再解剖。对这种罕见病症的病因和治疗选择进行了回顾和讨论。正畸治疗期间感觉异常的主要原因可能与牙根和下牙槽神经之间的接触有关，这在断层扫描中可能会清晰观察到。治疗通常包括朝着病症病因相反的方向移动牙齿。
