Anterior buccal mandibular depression (ABMD). Anatomic and histologic features.
The anterior buccal mandibular depression (ABMD) is a bilateral symmetrical depression located anterior to the mental foramen and extends under the alveoli of the first premolar to the central incisor. The prevalence, dimensions and contents of the ABMD in cadavers of fetuses and adult modern humans were evaluated. ABMD was found in all fetuses and in 31.8% of adults. The average dimensions of the ABMD in adults were depth 2.36 mm, width 5.44 mm and length 12.43 mm. The present study contributes to a better evaluation of the differential diagnosis and treatment planning in the anterior region of the mandible. A possible etiology for the development of ABMD is suggested.
