Abstract: The orthodontic archwire bracket comprises a base body (10) having a base element (11) to be fixed to a tooth and a bracket body (20) having a socket element (25) surrounded by a perimetric wall (32) including two opposed slot portions (21a, 21b) forming a slot (21) to receive an archwire. The base and bracket bodies (10, 20) are connected by a ball and socket joint coupling. The perimetric wall (32) has a slit (33) providing a gap. A control element (60) mounted on the bracket body (20) is changeable between locking and unlocking positions to expand or constrict the bracket body (20) by increasing or reducing the gap. The ball and socket joint coupling is locked by friction when the control element (50) is in the locking position and the ball and socket joint coupling is unlocked enabling relative movement in three coordinate axes when the control element (50) is in the unlocking position.

Abstract: Dental retention systems which facilitate the adjustment or removal of an oral appliance, e.g., a crown or bridge, from a reconfigurable abutment assembly are described. The adjustable abutment assembly may be secured to an anchoring implant bored into the bones within the mouth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy compression plates or elements extending along the projecting abutment portion. Each of the plates has a length with one or more straightened portions and with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion self-flattens to allow for the oral appliance to be placed thereupon while removal of the energy allows the elements to reconfigure into its curved configuration thereby locking the oral appliance to the abutment. Removal of the oral appliance may be effected by reapplication of energy to the elements.

Abstract: Methods are provided for shape-setting hyperelastic, single-crystal shape memory alloy (SMA) material while preserving the hyperelastic properties of the material. A wire or rod of a single crystal shape memory alloy material is heated to an annealing temperature (Ta). While maintained at the annealing temperature, the wire or rod is shaped by driving the wire or rod and a shaping form together into contact with each other, and the shaped wire or rod is quenched in a quenching medium virtually simultaneously with the shaping.

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: Articles made of shape memory alloys having improved fatigue performance and to methods of treating articles formed from shape memory alloy materials by pre-straining the articles (or desired portions of the articles) in a controlled manner so that the resultant articles exhibit improved fatigue performance. The shape memory articles are preferably medical devices, more preferably implantable medical devices. They are most preferably devices of nitinol shape memory alloy, most particularly that is superelastic at normal body temperature. The pre-straining method of the present invention as performed on such articles includes the controlled introduction of non-recoverable tensile strains greater than about 0.20% at the surface of a desired portion of a shape memory alloy article. Controlled pre-straining operations are performed on the shape-set nitinol metal to achieve non-recoverable tensile strain greater than about 0.20% at or near the surface of selected regions in the nitinol metal article.
