Nonextraction treatment of severe Class II, Division 2 malocclusions is presented. Timing, sequencing of appliance therapy, and segmental arch treatment are discussed. The effects of orthodontic treatment, pubertal growth, and postpubertal growth are illustrated with different growth responses. Corrections of the handicapping malocclusions were achieved by the development of arch circumference, torque, intrusion of incisors, and vertical buccal dentoalveolar development. Various subtypes of Class II, Division 2 malocclusion are presented. Pretreatment and posttreatment records are evaluated.
