An orthodontic appliance includes features for reducing friction between an interior of an archwire slot portion of the appliance and an archwire to be placed within the archwire slot. Other embodiments include a rounded exterior occlusal surface. Embodiments further include one or more receptacles for receiving an installation tool.

A modifiable orthodontic facebow is disclosed which is used with the head-strap and/or neck-pad for treating orthodontic cases. The modifiable orthodontic facebow of the present invention comprises an inner bow adapted to be inserted into a buccal tube of a molar band and an outer bow connected to the inner bow by means of an anterior hinge, wherein the anterior region of the outer bow is connected to the posterior region of the outer bow through a pair of side hinges comprising a first section and a second section, wherein the posterior region of the outer bow comprises a plurality of interconnected units, wherein a first interconnected unit is fixed to the second section of the side hinge followed by a plurality of intermediary interconnected units with a terminating unit comprising a j-hook to secure an elastic band.

An oral appliance that attaches to molars or bicuspids and that combines the capability for side-to-side and front-to-back expansion and contraction in one unit as a self-stopping mechanism. Further, this embodiment can be activated to compress or expand and be deactivated in two planes of side-to-side or front-to-back, along three different arms/bridges respectively. This is to say that one arm can compress front-to-back while the other arm expands, the jaw/teeth front-to-back, simultaneously). With proper arrangements and anchorage preparation the device shown and described can move front teeth forward or backward or back teeth forward or backward independently on either side of the mouth.

Methods and systems are provided for generating a treatment plan for arch expansion where a polymeric shell appliance is utilized to generate one or more activation forces that facilitate tooth movement. The polymeric shell appliances may comprise one or more tooth receiving cavities, in which each of the plurality of tooth receiving cavities is shaped and arranged to provide a counter moment of each of the plurality of teeth.

An intraoral telescoping spring includes a first tubular element, a second tubular element and a rod-shaped element. The first tubular element includes a first connecting element wherein the first tubular element has a first end and an open second end. The second tubular element is displaceably accommodated in the first tubular element and has a spiral spring, surrounds the first tubular element and extends in the direction of the first connecting element, and attached to the fourth end thereof to force the fourth end in a direction away from the second end. The rod-shaped element is displaceably accommodated in the second tubular element and has a second connecting element for connecting to the other of the two dental arches attached to the sixth end thereof. The spiral spring is attached to the fourth end of the second tubular element, so that the first and second tubular elements are detachably connected.

A method of using an orthodontic device to effect movement of an impacted or malpositioned tooth includes providing an orthodontic device, the orthodontic device including a bracket, a coiled spring, and an anchoring assembly, bonding the bracket to an impacted or malpositioned tooth, connecting a first end of the spring to a first spring attachment portion supported by the bracket, connecting a second end of the spring to a second spring attachment portion supported by the anchoring assembly, and coupling the anchoring assembly to a second orthodontic device that is installed in the patient's mouth.

An orthodontic appliance includes features for reducing friction between an interior of an archwire slot portion of the appliance and an archwire to be placed within the archwire slot. Other embodiments include a rounded exterior occlusal surface. Embodiments further include one or more receptacles for receiving an installation tool.

The invention relates to an orthodontic device which is particularly economical and as small as possible, and which has hooks and a small tube, produced from a sheet metal plate using stamping and bending techniques and without the use of welding or soldering. The orthodontic device comprises a base plate having a flat region with a gingival and an occlusal edge. An occlusal rolling forms the small tube. The gingival edge has a counter-directional rolling. Concave cuts are formed in the side edges in order to form wing-shaped hooks. Both rollings can hold an applicator/protector, with which the orthodontic device is protected during adhesion, and can then be applied to a tooth in the correct orientation.

The present disclosure provides an assembly and system allowing for secure use of an orthodontic auxiliary, particularly a bite corrector, with lingually bonded appliance systems. In one aspect, the disclosure features an orthodontic assembly including a banded tube, a force module, a connector coupling the force module to the tube, and an attachment device secured to the labial surface of an anterior tooth and connected to mesial, outer end of the force module.

The bony bracket screw has a cross-slot head or a Phillips head and a shank extending from the head, the shank having a smooth upper portion, a threaded lower portion, and a self-tapping or self-drilling tip. The screw has an annual flange defining a stop disposed between the smooth upper shank and the threaded lower shank. The stop may have a larger diameter than the head. The screw has a bracket arm extending from the smooth upper shank at an oblique angle. The free end of the bracket arm has a round retainer, which may be circular or cylindrical and defines a smooth bore adapted for supporting a distractor or other dental appliance. The screw may be made from stainless steel or other noncorrosive, biocompatible material.
