  • Patent number: 4755139
    Abstract: An orthodontic anchor appliance for repositioning anterior teeth of a dental patient includes a relatively hard splint portion for securement to preselected ones of the patient's posterior teeth positioned on opposite sides of the dental arch containing the anterior teeth desired to be repositioned and an elastic positioner portion joined to the splint portion for urging the anterior teeth to a preselected position. Both the splint portion and positioner portion are formed from appropriate materials which are pliable when a pre-hardened or pre-cured condition and are applied to and shaped about a diagnostic model of the patient's arch containing portions simulating the anterior teeth when positioned in the preselected position. When the appliance is operatively positioned within the mouth, the splint portion is closely fitted about and thereby anchored to the posterior teeth and the elastic positioner portion is closely fitted, about, in a flexed or deformed condition, about the anterior teeth.
