ABSTRACT:
This invention is a removable orthodontic therapy appliance adapted to be assembled and modified by an orthodontist without laboratory assistance, into a function regulator adapted to correct malocclusions of the teeth. It is a device of component parts of different sizes comprising: buccal shield base assemblies, buccal shelf extension assemblies, bicuspid - cuspid extension assemblies, a lip-pad, lingual roller assembly unit, a labial bow assembly and connecting means adapted to connect said assemblies into a function regulator. The invention provides an improved means for positioning the function regulator relative to the patient's dental arch, and it may be used in conjunction with band therapy. The invention reduces treatment costs, promotes patient cooperation during treatment, and permits the use of simultaneous fixed appliance therapy. In one embodiment of the invention it can be used primarily to promote positioning and or growth of the mandibular arch. A further advantage of the appliance of this invention is that it may be readily modified as treatment progresses.
