ABSTRACT:
The invention comprehends the use of a fixture which fits over a tooth on which a bracket is to be affixed, this fixture having an internal cavity which matches the shape and contour of a portion of the tooth, such as lingual surface, incisal edge and a portion of the labial surface. A second portion of the labial or lingual side of the fixture is fixedly secured to the head portion of the bracket in such a manner as to align the surface of the base in the same anatomical plane or tooth surface as the labial or lingual surface. The fixture may be rigid and of a material which can be changed to a non-rigid state upon application of a state-changing medium thereto. A second fixture or appliance essentially like the fixture may be non-rigid or flexible and conformable over the fixture in such a manner as to be easily removed therefrom and from the bracket. Removal from the bracket is performed after the fixture with the bracket mounted therein is assembled to a tooth and the bracket is bonded thereto.
