The present invention provides body anchored protraction devices. The protraction devices direct the negative forces of protraction over a large surface area on the chest and abdomen of a patient. The protraction devices employ a cantilever support rod and ultra-low friction joints to enable low compression on the head without restricting free movement.

A detachable orthodontic bracket and wire system includes bracket bases, brackets, and an arch wire for guiding alignment of teeth. The bracket bases are positioned on a lingual surface and/or a facial surface of the teeth. Each bracket base includes a first surface, a second surface, and at least one first interlocking element. The first surface is rigidly attached to the lingual surface and/or the facial surface of the teeth. The second surface opposes the lingual surface and/or the facial surface of the teeth. The first interlocking element is attached to and positioned in a direction substantially perpendicular to or parallel to the second surface of each bracket base. The brackets include at least second interlocking element that interlocks with the first interlocking element. The arch wire is inserted through a slot channel of each bracket. The bracket and the arch wire are infused and rigidly anchored within enclosing layers.

An aesthetic, partially removable orthodontic appliance is described, including a polymeric body that conforms to the lingual soft tissue and at least one wire member extending from the polymeric body. Each wire member releasably engages with a respective anchor that is, in turn, connected to the lingual surface of a respective tooth when the polymeric body is moved in a generally gingival direction into abutting relationship with the lingual soft tissue. Other features of the appliance include self-guiding magnetic couplings and couplings based on interlocking mechanical structures that provide releasable engagement between the removable section and the anchors, as well as related methods for making and using the same.

A facemask and accessories which overcomes the adverse effects and limitations of current designs by moving the maxilla and mandible in forward direction, which assists in correcting maxillary and mandibular skeletal and dentoalveolar deficiency and help expand the upper airway by advancing the mandible. This is accomplished by a design that is supported only by forehead and produces forces in front of maxilla and mandible. The extra-oral facebow design is characterized by providing two independent force adjustments, one above the forehead and the other one in front of the face by attachments to the upper and lower jaw bones and teeth. In particular, the two independent adjustments are provided by a fully adjustable forehead pad and bilateral adjustable bows on opposite sides of the facebow's extra-oral frame to provide protracting forces.
