A dental apparatus for measuring the height and width of a dental surface and for placement of a bracket at an exact position with respect to the dental surface. A first pair of opposing jaws are movable for measuring the long axis of the tooth. A second pair of opposing jaws are provided for measuring the mesio-distal width of the tooth. A pair of arms are confrontingly biased and can be spread apart to grasp opposing sides of the bracket for retaining the bracket prior to placement and for subsequent release of the bracket after placement. The instrument can be included within a servo mechanism for automatic control of the placement of the bracket at a calculated position. By integrating the system with a computer, the computer can provide an image of the tooth whereby the bracket placement can be predicted on the computer and then through the servo mechanism the instrument can be instructed for proper bracket placement.

An instrument for the placement of orthodontic brackets on dental surfaces comprising: a housing; a pair of arms supported by the housing, means for biasing the arms into a confronting relationship to grab opposing sides of a bracket for retention of the bracket prior to its placement on a dental surface; adjustable means on said housing for positioning the arms at any desired horizontal and vertical location with respect to the dental surface and not dependent on the dental cusp alone, for exact placement of the bracket at the desired location on the dental surface and release means on the housing for spreading both arms equidistantly apart from the desired location to release the bracket upon its being positioned at the desired location with respect to the dental surface.
