ABSTRACT:
This invention pertains to a direct bonding bracket positioning tool for orthodontists. A tweezer-type tool has the end of an outer jaw and an intermediate jaw configured and sized to receive and retain a cement-attached bracket as the bracket is directly bonded to the face of the tooth of the patient. For precise positioning of the bracket on the tooth there is provided a screw which is adjusted to position an extending jaw end, which is a third jaw, at a selected distance above the intermediate bracket retaining ends of the three jaw tweezer. This arrangement of jaw ends is depicted in two versions for the two most popular brackets in use. The adjustable top jaw is used to hold the gripped bracket in the selected position as and during the hardening of the bonding agent.
