基于CBCT的下颌神经管磨牙后区分支的影像学研究

Abstract

Abstract: Objective To explore the probability of the existence of the mandibular canal branch in retromolar region and its influence on clinical application through cone beam computed tomography (CBCT).Methods CBCT scanner was used to perform mandibular crosssectional continuous thin layer scanning and multiplanar reconstruction on patients to study the distribution and direction of mandibular canal branches in retromolar region.Results Among the total 416 sides of mandibular canal,there existed 79 sides of mandibular canal branch in retromolar region and the rate was 18.99%.The Branches were located above the trunk,and distributed in the distal or inferior area of the mandibular third molar (if there was no mandibular third molar,then branches were distributed in the distal area of the mandibular second molar).Conclusions The probability of the existence of the branch in retromolar region and its distribution and direction obtained from this study is the theoretical basis for clinical oral and maxillofacial surgery.
