Abstract: A self-ligating orthodontic bracket for ligating an archwire includes a bracket body defining an archwire slot configured to receive the archwire, a movable member movable relative to the archwire slot, and an actuator coupled to at least one of the bracket body and the movable member. The actuator includes a ferromagnetic shape memory alloy and is configured to move the movable member when exposed to a magnetic field. A method of orthodontic treatment using a self-ligating orthodontic bracket having an archwire slot configured to receive an archwire therein and including a ferromagnetic shape memory includes exposing at least a portion of the orthodontic bracket to a magnetic field such that the ferromagnetic shape memory alloy at least partially transforms to a martensitic phase from an austenitic phase, and at least one of inserting an archwire into the archwire slot and removing an archwire from the archwire slot.

Abstract: A fatigue-resistant Nitinol instrument has a working portion in the deformed monoclinic martensitic state and an austenite finish temperature in the range of 40° to 60° C. Because the operating environment of the instrument is about 37° C., the working portion remains in the monoclinic martensitic state during its use. The relatively high austenite finish temperature and fatigue resistance is achieved by subjecting the nickel-titanium alloy to a final thermal heat treat in a temperature range of about 410° to 440° C. while the nickel-titanium alloy is under constant strain of about 3 to 15 kg. Further, the high austenite finish temperature is achieved without subjecting the alloy to thermal cycling to produce shape memory. Additionally, there are no intermediate processing steps occurring between obtaining a finished diameter of the wire or blank through cold working and the final thermal heat treat under constant strain.

Abstract: Disclosed is a method for producing an orthodontic appliance for securing to a user's teeth in order to carry out an orthodontic treatment, the appliance having an element. The method includes a) gathering information relating to the user's set of teeth; b) using the information to determine at least first and second stable shapes of the element towards which the element should tend to deform during the first and second periods of treatment, respectively; and c) producing and programming the element in such a way that the application of a stimulus during the first period of the treatment renders the second stable shape operational. In certain aspects in step c), a retractable or expansible material is incorporated into the element.
