An American Board of Orthodontics case report: treatment of a crowded Class II malocclusion in an adult.

A case report is presented of an adult with a crowded Class II, Division I subdivision left malocclusion. There was a moderate arch length deficiency in both arches. All four canines were prominent and had gingival recession. The patient's profile necessitated nonextraction treatment. Free gingival grafts were placed to prevent further recession and the Class II relationship and crowding were resolved with a positive profile change. [This case was presented to the American Board of Orthodontics in partial fulfillment of the requirements for the certification process conducted by the board.]
