Abstract

Dental implant placement in the posterior mandible can be impacted by the presence of the lingual concavity. Perforating the lingual cortical bone could lead to life-threatening hemorrhage/airway obstruction. The aim of this retrospective study is to examine dentate and partially edentulous mandibles to describe anatomical variations related to the lingual concavity by evaluating cone beam computed tomography (CBCT).
