Abstract: A method of imparting a particular shape to a wire made of a shape memory alloy, such as a Ni-Ti alloy, which includes the steps of bending the wire inside a tubular body into the particular shape; heating the wire within the tubular body to a temperature sufficient to cause the wire to retain the particular shape; and removing the wire from the tubular body. The tubular body is made of a deformable metal, such as stainless steel or nickel-chrome alloy tubing, and includes a slit therethrough extending in its axial direction. The slit is provided to facilitate bending the tubular body and removing the wire from the tubular body.

Abstract: A continuous-length orthodontic coil spring is made from a shape-memory alloy wire wound into a coil. The coil defines a plurality of open coil sections defining spaces between the turns thereof, and closed coil sections formed between the open coil sections. The closed coil sections are tightly wound with insubstantial spacing between the turns thereof. The coil spring is made of a Ni-Ti alloy wire, and is heat treated to impart a predetermined range of spring force within a superelastic zone of deflection. The continuous-length coil spring is cut through the closed coil sections to form several shorter-length coil springs therefrom. The closed coil sections on either end of the shorter-length coil springs are thus adapted to engage the orthodontic brackets mounted to a patient's teeth, to accurately impart the force of the spring to the brackets.

Abstract: A plurality of strands are disposed in a braided relationship to form a multi-strand filament. Each of the strands is formed from a material having substantially fifty five percent (55%) titanium and forty five percent (45%) nickel by weight. The strands have the properties of being formed to any desired configuration in an arched relationship at a suitable temperature such as approximately 490.degree. C. The multi-strand configuration is then bent from the desired configuration at a temperature below a particular temperature such as 10.degree. C.-15.degree. C. to conform to the actual configuration of the teeth in the patient's mouth and is attached to the patient's teeth in this bent configuration. The multi-strand filament returns to the desired configuration while attached to the patient's teeth, thereby causing the position of the teeth in the patient's mouth to become disposed in the desired configuration. In another embodiment, the multi-strand braid envelopes a centrally disposed wire. The centrally disposed wire may be made from the same material as, or a different material than, the braids, depending upon the characteristics desired.

Abstract: An orthodontic shape-memory alloy archwire for ligating to orthodontic appliances is heat treated, so that different sections of the archwire each exhibit a predetermined modulus of elasticity, and therefore impart a predetermined range of force when deflected. The distal ends of the archwire are further heat treated, or are treated with a dopant, to exhibit substantially diminished superelastic properties in comparison to the other sections of the archwire. The distal ends can therefore be deformed into shapes when ligated to orthodontic appliances to secure them to the appliances, and thus prevent them from slipping therethrough.
Abstract translation: 将用于与正牙器具连接的正畸形状记忆合金弓丝进行热处理，使得弓丝的不同部分各自呈现预定的弹性模量，因此在偏转时施加预定的力范围。 与弓丝的其它部分相比，弓丝的远端进一步热处理或用掺杂剂处理，显示出显着降低的超弹性。 因此，当连接到正畸器具以将它们固定到器具上时，远端可以变形成形状，从而防止它们从其中滑出。

Abstract: An enossal implant for securing a tight-fitting tooth replacement having two parts which are to be connected with one another. One part, having a bore hole, is placed in the jawbone. The other part, comprising a peg which serves to hold the replacement tooth, is replaceably inserted in the hole. The diameter of the cylindrical external wall of the peg is dimensioned larger than the diameter of the bore hole so that the peg, at body temperature, is compressed within the bore hole, but at reduced temperature can be removed from the bore hole due to reduction in the external dimensions of the peg. Such a connection is simple to handle, cannot loosen, and is practically free of cavities so that no bacterial colonies can form in the implant.

Abstract: Orthodontic movement of malaligned teeth is performed by attaching to the teeth a wire which has properties useful in orthodontics. When the anticipated use of the wire involves torsional and flexural stresses, the wire is a single strand of a material having a higher elastic limit and a lower elastic modulus than an 18-8 stainless steel wire of identical cross-section. The invention also contemplates the use of wires which demonstrate a plastic memory which causes them to return to a preset shape or length after being deformed and then heated. For example, longitudinally shrinkable wires are either attached to teeth for closing the spaces therebetween or are used to draw a tooth toward a fixed reference member such as a rigid archwire spaced from the tooth. The mechanical memory of the wire may also tend to restore it to a preset shape upon heating in order to level or torque malposed teeth. The disclosed wires are formed of Nitinol alloy which is a known near-stoichiometric alloy of nickel and titanium. When the wire exerts tooth-moving forces by being subjected to torsional or flexural stresses, the alloy also includes cobalt substituted for nickel on an atom-for atom basis so that the composition is TiNi..sub.935 Co..sub.065.

Abstract: An orthodontic appliance includes a portion made of a shape memory alloy having a base alloy composition of at least two different metallic elements and a treated region having an alloy composition that is depleted in at least one of the metallic elements. The base alloy may include a nickel titanium alloy (NiTi), a copper chromium nickel titanium alloy (CuCrNiTi), or a copper aluminum nickel (CuAlNi) alloy. The treated region may be depleted in at least one of copper, aluminum, nickel, and titanium relative to the base alloy composition by exposing the base alloy to a source of energy. The base alloy composition has a first austenitic finish temperature and the treated region has an austenitic finish temperature that may be different than the first austenitic finish temperature. The treated region may form a part of an archwire, a stop, a hook, a crown, a band, or an orthodontic bracket.
