Abstract

Buccal nonocclusion is a difficult situation for orthognathic surgeons. This is the severest form of crossbite with congenital or traumatic origin. Unilateral cases are more difficult and need more attention. Posttrauma-acquired buccal nonocclusion is easier for management than congenital cases that need orthodontic preparation and more complicated orthognathic surgeries. Two cases of trauma-induced unilateral buccal nonocclusion are presented with different etiologies. Preoperative model surgery and posterior segmental surgery are keys to correct trauma-induced buccal nonocclusion.
