Abstract
Both fixed and removable functional appliances are disclosed employing magnets to provide the requisite force for accomplishing Class II malocclusion correction. Magnets are employed buccally and/or lingually, either operating in sliding or shearing mode or with the inter-pole gap inclined mesio-distally to develop an effective horizontal force component. Long thin rectangular magnets are incorporated bilaterally and inclined mesio-distally in the tooth capping sections of functional type base structures overlying the occlusal surface. Curved or angled straight magnets are located in anterior flanges of functional type base structures for developing horizontal thrust on the mandible. A number of closed magnetic circuits using either low reluctance keepers or shaped magnets are described for providing either increased force or travel or both.
