Abstract: Root canal abutment devices and methods 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 within a pulp chamber of a pre-existing tooth. The abutment assembly has a projecting abutment portion with one or more shape memory alloy sleeves or plates or elements extending along the abutment. Each of the sleeves has a length with at least one curved or arcuate portion. Energy may be applied to the elements such that the arcuate portion 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: 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: 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: A method is for fabricating a device for injecting a filler material in the fluid phase into a root canal space, the device including an adapter nozzle, an auto-mixer connected to the adapter nozzle, an intra-oral injection nozzle positioned at the upper end of the auto-mixer. The method includes using a shape memory material to make the injection nozzle so as to be bendable according to a desired orientation. The method also includes arranging on the exterior surface of the injection nozzle, circular ribs defining a groove, and moulding the upper end of the auto-mixer in this groove so that the injection nozzle is lodged in position in the upper end while retaining a degree of freedom in rotation around its axis of symmetry, or one or multiple circular ribs parallel to each other.
