Abstract
Abstract The orthodontic appliance comprises a palatal appliance having upper and lower surfaces which is adapted to be inserted into the patient's mouth with the upper surface in surface contact with the palate. A plurality of wire members are attached to the lower surface of the palatal appliance. The wire members each have three sections which respectively project from the lower surface, across the dental arch and to the outside thereof when the palatal appliance is inserted into the mouth of the patient. An arch wire having first and second ends is attached to orthodontic brackets that have been bonded to the patient's teeth. The ends of the arch wire are activated by respectively coupling them to the third section of a pair of the wire members. The coupling of the ends of the arch wire to the wire members obviates the need for buccal tubes to activate the arch wire. The arch wire comprises a section of wire having built-in occulsalgingival torque when the ends of the arch wire are activated by attachment to the appliance discussed above or to a conventional buccal tube. The method of the present invention consists of three phases of treatment. The first phase comprises attaching a plurality of conventional orthodontic brackets to the teeth, attaching a first arch wire to the orthodontic bracket without activating the ends of the arch wire by coupling them to teeth and then applying conventional correction forces to the teeth. The second phase comprises removing the first arch wire, attaching a second arch wire, activating the ends of the second arch wire by coupling its ends with the appliance discussed above, and then applying conventional correction forces to the teeth. The third phase comprises removing the second arch wire and attaching a third arch wire as described above which has built-in torque when the ends of the third arch wire are activated by coupling with the appliance discussed above and then applying correction forces until the orthodontic treatment is completed.
