CLASS-II SUBDIVISION TREATMENT WITH TIP-BACK MOMENTS

Unilateral tip-back mechanics are challenging because of a number of u ndesirable side-effects associated with their use during orthodontic t reatment. The purpose of this paper is to review the differential diag nosis and treatment planning of Class II subdivision malocclusions and present a treatment strategy based on a careful biomechanical analysi s of the clinical situation. Emphasis is placed on the correction of m olar axial inclination using unilateral tip-back moments in the treatm ent of dental asymmetries. Appliance design and treatment sequencing a re also discussed.
