Black Female's Anatomical Structure of the Chin

Description

Shown in lateral profile, the anterior mandible forms the contour of the chin from the inferior border of the body of the mandible up toward the alveolar process beneath the lower lip. The blue-highlighted point corresponds to a surface landmark at the midline mental prominence, typically referenced as pogonion on cephalometric analysis, with menton lying slightly inferior on the lowest point of the mandibular symphysis. Overlying soft tissues include the chin pad and mentalis region, positioned anterior to the mandibular symphysis and inferior to the labiomental fold. Chin projection is a small region with outsized implications in dentofacial diagnosis. Orthognathic planning often tracks pogonion and menton to quantify mandibular retrusion or prognathism, and to model soft-tissue response after bilateral sagittal split osteotomy or sliding genioplasty, where even a few millimeters of advancement can change the labiomental angle and lower facial height. For injectors and facial surgeons, the lateral chin also sets the safe approach around the mental foramen region and mental nerve distribution, helping avoid paresthesia during implant placement, filler augmentation, or scar revision after laceration. Use this asset in dental anatomy, orthodontics, and maxillofacial surgery teaching when explaining cephalometric landmarks, facial proportions, and the external correlate of the mandibular symphysis in a Black female adult patient. It also fits patient-facing education for genioplasty, chin implant consultation, and documentation of preoperative versus postoperative profile change.
