Abstract
Overbite reduction is a key element of orthodontic treatment, particularly in Class II division 2 malocclusion. Traditionally, during isolated fixed appliance therapy, overbite reduction follows the alignment phase and precedes overjet reduction and space closure. This involves levelling of the curve of Spee in the lower arch with relative extrusion of the posterior teeth and is reliant on engagement of stiff stainless steel lower arch wires of large dimension (e.g. 0.019 × 0.25-in.) often with exaggerated reversed curves to promote further extrusion (Chap. 9). Increasingly, however, earlier overbite reduction can be considered using a range of adjuncts and techniques during the initial alignment phase.
