title: Adult Class II Division 1 patient with severe gummy smile treated with temporary anchorage devices.
abstract: A 23-year-old Mongolian woman came for a consultation with chief complaints of protrusive lips and a gummy smile. The clinical examination showed a convex profile, a protrusive maxilla, excessively proclined and extruded maxillary incisors, and a Class II Division 1 malocclusion. Temporary anchorage devices (TADs) in the posterior dental region were used as anchorage for the retraction and intrusion of her maxillary anterior teeth. Those appliances, combined with a compensatory curved maxillary archwire, eliminated the severe gummy smile and the protrusive profile, and corrected the molar relationship from Class II to Class I. With no extra temporary anchorage devices in the anterior region for intrusion, the treatment was workable and simple. The patient received a satisfactory occlusion and an attractive smile.
