种植支抗辅助拔除毗邻神经管近中阻生智牙14例报道

目的 探讨应用微种植支抗牵引毗邻下牙槽神经管的近中阻生智牙,减小拔牙术后不良反应的效果。方法选择14例锥形束CT确诊毗邻下牙槽神经管且近中阻生的智牙,微种植支抗牵引下颌智牙2~5个月,待其离开下牙槽神经管后拔除。结果所有患牙均顺利拔除,拔牙后均无明显的术后反应。结论应用微种植支抗牵引后拔除毗邻下牙槽神经管的近中阻生智牙,是一种可靠的微创拔牙方法。

Application of miniscrew for extraction of mesially impacted wisdom tooth adjacent to the inferior alveolar nerve canal

PURPOSE: To study the value of miniscrew for extraction of mesially impacted wisdom tooth adjacent to the inferior alveolar nerve canal. METHODS: Fourteen mesially impacted wisdom teeth were proven to be adjacent to the inferior alveolar nerve canal by means of cone-beam CT scan. The treatment began with the miniscrew traction of the wisdom teeth. After 2~5 months, they were moved away from the canal and then extracted. RESULTS: After extraction, all 14 cases did not show any obvious side effect. CONCLUSIONS: Application of miniscrew traction is a valuable method for minimally invasive extraction of mesially impacted wisdom tooth that is adjacent to the inferior alveolar nerve canal.
