KIDS: a new approach to distalize maxillary molars.

Precise distalization of maxillary molars is of significant value for nonextraction treatment of Class II malocclusion associated with a normal mandible. Most of the distalizing appliances available today produce adverse effects, eg, molar tipping and rotation, incisor proclination, and lack of anchorage control during the space-consolidation phase. To address these shortcomings, a new appliance (Karad's Integrated Distalization System; KIDS) has been designed to distal drive maxillary molars using light continuous forces in a predetermined direction, with good molar control during the distalization and anchorage control during the space-consolidation phase of treatment. This appliance eliminates the need to construct a new Nance appliance to stabilize the molars in their new positions after distalization. This article describes the construction and the clinical management of the appliance.
