ABSTRACT:
Transpalatal orthodontic appliances are disclosed which utilize a shape-memory or superelastic alloy member as the force-supplying member of the device. Suitable alloys include the nickel-titanium (NiTi) alloys, the titanium-molybdenum alloys (TMA), and any other alloy composition which possesses superelastic or shape-memory characteristics. The alloy composition may preferably have a working rang of at least about 30% and a modulus of elasticity not exceeding about 15.times.10.sup.6 psi.
