ABSTRACT:
The invention described facilitates accurate placement of orthodontic brackets on a patient's mal-occluded teeth. An indexed dental cast of the patient's mal-occlusion is produced by the present apparatus. In process steps for indexing the crown model, various adjustment devices hold a selected mal-occluded crown model of the cast in an "ideal" or corrected position in space. The cast is thus positioned and held while a drill is used to form index holes in the cast material. The index holes record the "ideal" position of the selected crown model even though the crown model remains in its original mal-occluded position in the cast. Positioning of a bracket against the selected crown model is accomplished by a bracket holder and adapter using the index. The holder receives the bracket while the adapter is positioned, using probes inserted into the index holes. The holder may be moved to a selected tip angle and bracket placement height through adjustments on the adapter. The holder may also be precisely positioned to locate a bracket in a selected in and outs position in relation to the crown model.
