The case report described the orthodontic treatment of a 13-year-old male patient diagnosed as Angle Class II Division 1 subdivision left malocclusion with deep bite and spacing. The chief complaint was protrusive upper front teeth prone to injury. Non-extraction treatment with Forsus appliance and Class II elastics was used to correct the Class II relationship on the left side, and to improve the deviated mandibular dental midline, protrusive front teeth and lips, and lip incompetence. Although there were residual mandibular dental deviation of 0.5 mm and lip incompetence, the patient and his parents were satisfied with the treatment results revealing improvement of facial appearance and achievement of Class I molar and canine relationship with solid interdigitation.
