摘要:
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.
