Abstract: A quantity of a photocurable composition, such as an orthodontic adhesive containing a photoinitiator, is placed between the base of an orthodontic appliance and a replica of a patient's tooth structure. The replica is made using a material that transmits actinic radiation. As the appliance is pressed into firm contact with the replica tooth structure, an outer surface of the photocurable composition assumes the configuration of the underlying portion of the replica tooth structure. Actinic radiation is then directed to the photocurable composition, and at least part of the actinic radiation is directed through the replica tooth model in order to harden the photocurable composition. The hardened composition provides a contoured bonding surface having a shape that matches corresponding regions of the patient's tooth structure. Methods are also disclosed for making an orthodontic indirect bonding transfer apparatus for use with appliances having a contoured bonding surface.

Abstract: An adjusting tool and associated method of use for turning orthodontic expansion screws are described. The tool or device consists of a contra-angled molded plastic handle or housing with a rotatable pin at the distal end for inserting into an expansion screw located in a patient's mouth. The tool housing is designed to limit the angular rotation of the pin to the arc required for insertion and subsequent activation of the orthodontic screw. When rotated to the position associated with screw activation, the pin is captured and held in place by a locking mechanism which then requires the tool to be disengaged from the screw prior to its removal from the patient's mouth. This feature eliminates the possibility of reversing and deactivating the expansion screw by pulling the expansion key straight out of the mouth. A manual release mechanism on the tool frees the pin to allow the pin to be rotated back to the insertion position.

In particular, a method of archwire selection comprises (a) obtaining a representation of a patient's inner arch curve (a “PIAC”); (b) selecting an archwire shape based at least partially on the PIAC representation; (c) making an initial selection of an archwire size based at least partially on the PIAC representation; (d) selecting a final archwire size after considering something other than the PIAC representation; and (e) selecting an archwire to be used based on the selected archwire shape and selected final archwire size. Using the PIAC rather than the occlusal or labial and buccal surfaces of the teeth for archwire shape selection promotes shaping the teeth to the shape of the jaw bone and gives consistent facial esthetics plus better retention of the treatment correction.
