Assessment of Relation and Course of Inferior Alveolar Nerve Using CBCT-A Retrospective Study of 120 Cases

Inferior alveolar nerve injury is most common postoperative complications while performing surgical procedures in close proximity to the Inferior alveolar neurovascular bundle such as Extraction ofthirdmolar, Placement of intraosseousimplants, Placement of screws, Bilateral sagittal split osteotomy, Genioplasty in orthognathic surgery, Inferior Alveolar Nerve lateralization, Body Osteotomy, Distraction Osteogenesis, Massetric hypertrophy. So, the relation and course of the inferior alveolar nerve is important to avoid injury to the nerve. The aim of the study is to assess the course of mandibular nerve from its entry to exit from mental canal and to evaluate the distance of the inferior alveolar nerve canal with 3rd molar.
