Assessment of prevalence, length and position of anterior loop of inferior alveolar nerve: a study using CBCT
Introduction: Adequate space is required in the interforaminal region for anterior mandibular surgery, where the anterior loop is located within this region. The aim of this study is to evaluate the prevalence of the anterior loop (AL) of the inferior alveolar nerve, and to measure its length and po...
