A new Class II distalizer.

JCO/APRIL 2004 T Carrière Distalizer* is a simple and efficient fixed functional appliance for Class II treatment (Fig. 1). Developed by the author with advanced computer technology, it represents an evolution of the Modular Sectional Arch.1 The Distalizer is most effective in treating Class II malocclusions without extractions. Brachyfacial patterns respond best to treatment; dolichofacial types are less responsive. The appliance can also be used in many Class I cases with mesially positioned maxillary molars or, with caution, in Class I cases with premaxillary hypoplasia. Growing patients are ideal, but adults can be treated as well. Mixed dentition Class II cases with fully erupted first molars are candidates for first-phase treatment.
