ABSTRACT:
This invention pertains to an improved orthodontic appliance which includes a tubular member pivotally attached to a plate member. This plate member is attached to a band secured to a tooth of a patient. The tubular member is limited in its swing by detents provided on the plate. A power force, which may be a spring biased piston and wire shank or may be a headgear apparatus, is mounted in this pivoted tubular member. The biased piston module may be secured to a moulded retainer for removable use in the mouth of a patient. The pivoted tubular support enables easy removal of the power force for cleaning and adjustment. With a biased piston there is provided an adjustable stop so that a determined force may be applied during repositioning of a tooth.
