Abstract
This invention relates generally to orthodontic apparatus for applying an array of brackets to a cast matrix of teeth. The apparatus is particularly useful in the practice of a novel method invented by applicant which is also disclosed herein. The apparatus essentially comprises a pair of first and second supports mounted relative to each other for rectilinear movement, a plurality of grippers for holding and supporting an arch wire in a plane substantially parallel with the direction of rectilinear movement, and means for adjustably mounting said grippers to adjust the spacing therebetween and position the grippers relative to said first and second supports, whereby a cast matrix of teeth can be positioned on said second support in juxtaposed relation to a plurality of brackets mounted on an arch wire supported by said grippers and moved simultaneously into and out of precise contact with the brackets.
