The orthodontic treatment of a young adolesent female with a high Angle Class II Division 1 malocclusion is presented. Successful treatment required a careful diagnosis, specific planning, and efficient biomechanical control of the force systems to correct the disharmony in the vertical and horizontal dimensions. En masse retraction of the six maxillary anterior teeth was done via a Kalra simultaneous intrusion and retraction archwire. Precise mechanics with excellent vertical control made it possible to successfully correct the malocclusion without undesirable sequelae. ORTHODONTICS (CHIC) 2012;13:e116–e126.
