Patient with spaced, flared teeth (like piano keys). Chief complaint is spacing and tooth position. Panoramic X-ray, photos, and cephalometry are shown. What is this patient's profile?

Correct answer: C. Convex

• A. A straight profile would not typically be associated with significantly flared/proclined anterior teeth.
• B. Brachycephalic describes head shape (cranial proportions), not facial profile in this context.
• C. Correct. Flared, spaced anterior teeth (protrusive incisors) are associated with a convex facial profile, where the lips/maxilla project relatively forward.
• D. A concave profile is associated with a retrusive maxilla/prognathic mandible — the opposite of flared, protruded incisors.
