Treatment of a patient with a Class II malocclusion, impacted canine, and severe malalignment.

A case report of the orthodontic treatment of a male adolescent with a unilateral dental Class II malocclusion, an impacted canine, severe maxillary malalignment, and a canted maxillary anterior occlusal plane. Treatment consisted of full fixed appliances, extraction of the maxillary right first premolar, and surgical exposure of the impacted canine. Treatment vastly improved the patient's facial and dental esthetics. A Class I skeletal and dental relationship was established, along with a functional anterior guidance. The dental arches were coordinated and the dental midlines coincident with the midsagittal plane. This case report was presented to the American Board of Orthodontics in partial fulfillment of the requirements for the certification process conducted by the Board.
