    Abstract: An improved dental appliance system, and methods for using and fabricating the improved appliance, including a polymeric overlay or shell having a teeth-receiving cavity formed therein. The dental appliance having the necessary stiffness or strength to firmly secure the appliance on the teeth and provide controlled forces required for repositioning the teeth, until such time as removal of the appliance is desired. The appliance may be configured for use with a removal mechanism. The removal mechanism provides for selective release of the appliance from the teeth as the removal mechanism undergoes a state change stimulated by an environmental stimulus or environmental switch.

    Abstract: An endodontic file is provided that is fabricated from a superelastic alloy material such as an alloy of nickel, titanium and niobium. The superelastic alloy material is selected to have a relatively high loading plateau greater than about 500 MPa. Such alloy material allows the formation of precision ground flutes and cutting edges with reduced incidence of burrs, rolled metal deposits and other imperfections. Thus, the cutting edges of an endodontic file constructed in accordance with the invention are sharper and cleaner than heretofore achieved and less susceptible to wear. The resulting file is also stiffer than comparable files fabricated from conventional NiTi alloys such that improved tactile feedback and manipulation control are provided.

    Abstract: An electromagnetically induced cutting mechanism provides accurate cutting operations on soft tissues. The electromagnetically induced cutter is adapted to interact with atomized fluid particles. A non-thermal tissue remover comprises an aspiration cannula housing a fluid and energy guide for conducting electromagnetically induced mechanical cutting forces to the site within a patient's body for aspiration of soft tissue. The cannula is provided with an aspiration inlet port adjacent the cannula distal end. The proximal end of the cannula is provided with fluid flow connection to an aspiration source. Separated soft tissue and fluid are aspirated through the aspiration inlet port and the cannula by an aspiration source at the proximal end of the cannula.

    Abstract: A medical or dental probe having a resistive, integrally heated tip including a superelastic material such as nickel-titanium alloy. The probe tip provides a nearly continuous, controllable heat, and it may have a narrow, pointed shape. The tip may be heated rapidly, and it provides rapid heating of the instrument, continuous supply of heat for the purpose desired, and concentration of maximum heat at the end of the tip. The added flexibility allows the tip to follow the curvature of a canal of a tooth without the need to pre-bend the tip which increases the working life of the tip and provides for improved packing of the material used to fill the root canal.

    Abstract: A medical device which comprises a shape memory alloy (SMA) portion which is deformable from an undeformed first configuration assumed by it in an austenitic state of the SMA to a deformed second configuration, whereby the SMA is converted into a strain-induced martensite or partial martensite. This conversion increases the temperature of transformation (A.sub.s) from an initial transformation temperature A.sub.s .degree. to a temperature A.sub.s '. When the SMA, once in the second configuration, is heated to a temperature higher than A.sub.s ', it transforms to an at least partial austenite and it transforms towards the undeformed first configuration with a decrease of A.sub.s from A.sub.s ' to A.sub.s .degree.. A.sub.s .degree. is below body temperature such that when the device is deployed in the body, after placing it in its target location with the SMA portion in the second configuration and then heating it to assume its first configuration, the SMA is stable in the at least partial austenite at body temperature.

    Abstract: Self-ligating orthodontic brackets comprise a spring ligating member of U-shape with converging arms movable on the bracket body between slot open and closed positions; in the latter position the spring retains an arch wire in the slot and urges the bracket and wire to their optimum relative positions. The ligating member is of a superelastic shape recovery metal alloy, preferably of thickness from 0.20 mm (0.008 in) to 0.25 mm (0.010 in), with rounded edges. At least the lingual portion of the member to be stiffer than the remainder; at least a part of the occlusal portion can also be stiffer. Alternatively, or in addition, the bracket body has a large mesial distal extending bore between and spaced from the bracket occlusal, lingual and labial surfaces and the arch wire slot occlusal surface. The large bore accepts attachment members used for attachment of a range of auxiliaries, such as hooks and traction springs. Alternatively, or in addition, the arch wire slot gingival wall comprises an additional spring; this can be of shape memory alloy and preset to become effective when heated above its transformation temperature. Alternatively, or in addition the arch wire slot has the lingual and gingival surfaces meeting at an angle from 120 to 150 degrees to provide a larger slot; the slot gingival surface may also be provided by an additional spring member.
