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.
颊下颌前凹陷（ABMD）是位于颏孔前方的双侧对称凹陷，向前延伸至第一前磨牙牙槽下方，直至中切牙。对胎儿和成年现代人尸体中ABMD的患病率、尺寸和内容物进行了评估。在所有胎儿和31.8%的成年人中发现了ABMD。成年人ABMD的平均尺寸为深度2.36毫米、宽度5.44毫米和长度12.43毫米。本研究有助于更好地评估下颌前部区域的鉴别诊断和治疗计划。提出了ABMD形成的一种可能病因。
