摘要/Abstract

摘要： 目的: 探讨应用双种植支抗钉牵引拔除紧邻下牙槽神经管水平阻生智牙的临床效果。方法: 选择正畸科转诊要求拔除锥形束CT确诊紧邻下牙槽神经管的水平阻生智牙8例,双种植支抗钉配合悬臂梁牵引智牙6~9个月,当与下牙槽神经分离后予以拔除。结果: 所有患牙拔除后均未出现下牙槽神经麻木症状。结论: 应用双种植支抗钉牵引拔除紧邻下牙槽神经管的水平阻生智牙是一种高效、可靠的治疗方法。

Abstract: PURPOSE: To study the clinical effect of double miniscrews for extraction of horizontally impacted wisdom tooth adjacent to the inferior alveolar nerve canal. METHODS: Eight horizontally impacted wisdom teeth requiring extraction because of orthodontic treatment were proven to be adjacent to the inferior alveolar nerve canal by means of cone-beam CT scan. The treatment began with double miniscrews traction under the help of cantilever beam. After 6~9 months, they left the canal and then were extracted. RESULTS: After extraction, no patient developed lip numbness. CONCLUSIONS: Application of double miniscrews traction is an efficient and reliable method for extraction of horizontally impacted wisdom tooth that is adjacent to the inferior alveolar nerve canal.
