Introduction: The aim of this study was to radiographically assess the region between the mental foramina for the presence and characteristics of mandibular incisive canal, a major repair associated with postoperative complications of osseointegrated implant placement surgeries. Material and Methods: Fifty-two edentulous patients treated during twelve months in the Dental Clinics of the Federal University of Bahia underwent digital panoramic examination. The images were evaluated by a single radiologist and the presence of the mandibular incisive canal, its length, the shape of its trajectory and the distances from the alveolar crest and mandibular base were recorded. Results: The final sample consisted of 49 exams. Mandibular incisive canal was observed in eight radiographs, and accounted for 16.3% of the population investigated, with length varying from 10.7 to 19.7 mm. Bilateral lesions were more frequent (50%), and so was the horizontal path (5 cases). Final consideration: The presence and intraosseous anatomy of mandibular incisive canal should not be ignored in surgical planning involving the anterior mandible region. This becomes critical to prevent perioperative complications and also to prevent the occurrence of sensory and bleeding disorders in the postoperative period.
