Dental instrument and method for positioning a lingual orthodontic bracket

摘要

A dental instrument and method for positioning a lingual orthodontic bracket is disclosed. The instrument comprises a housing on which is positioned a first arm that includes means for releasably holding the orthodontic bracket. A second arm, which cooperates with the first arm, also cooperates with the housing in such a manner that the spacing between the buccal surface of the tooth and the base of the slot in the bracket that is used for the support thereof may be rapidly determined. Level indicating means are used for displaying the extent of inclination of the first arm with respect to a predetermined plane. Means are also provided for angularly orienting the slot by which the bracket is supported with respect to a predetermined plane. Also described is the combination and cooperation of a novel lingual orthodontic bracket and a novel orthodontic instrument for use with the bracket.
