Abstract
Abstract An orthodontic method and appliance for treating malocclusion comprising the steps of forming a model of the patient's teeth in the form of a dental arch with the replicas of the teeth in idealized locations, establishing on the labial and buccal surfaces of the replicas locations which conjointly define an idealized dental arch configuration, providing on each selected surface at the established location an orienting embossment, and forming onto the crown and surface, including such embossment, in intimate conforming engagement, of each selected replica a plate-like fixture which has an exterior provided with a locating boss corresponding to the shape of the embossment and a mounting surface surrounding the boss which corresponds to the replica surface. A bracket is provided having a socket which intimately fits over the boss thereby to be oriented with respect to the fixture. The fixture is transferred from the replica to the corresponding tooth in the patient's mouth with the custom formed base portion of a fixture which underlies the boss being suitably bonded to the tooth. The remaining portion of the fixture, principally that which overlies the crown, is then separated or broken away leaving the base portion of the fixture with the attached bracket bonded to the tooth.
