Abstract
In an apparatus for precisely locating an orthodontic bracket at a predetermined position on a surface of a tooth, orthodontic brackets for holding orthodontic wires can be easily and precisely located at and adhered to a predetermined position on a surface of a tooth, not only at an initial time but also even when the used orthodontic brackets are separated from the surface of the tooth in the course of the orthodontic treatment. The apparatus has a suspension body, a ring, and a molding spacer. The suspension body is disposed extending in parallel with the tooth from an apex toward a dental root of the tooth with a predetermined gap. The ring is inserted in the groove and hooked around the hook after the holding member has been fittedly inserted in the fitting recess, to thereby tightly assemble the suspension body and the orthodontic bracket together. The molding spacer is disposed between the suspension body and the tooth.
