Abstract: A method of forming a dental tool or instrument having a memorized shape. The method comprises selecting a nitinol wire having an initial transition temperature below room temperature; grinding the nitinol wire to form the dental tool or instrument so as to have a shank, located adjacent a first end, and a working area, with at least one cutting edge, located adjacent an opposite second leading end; molding the working area into a molded shape having at least one protrusion formed therein; heating the dental tool or instrument to both: a) alter the initial transition temperature of the dental tool or instrument to a final transition temperature, and b) memorize the Molded shape including the at least one protrusion so that the dental tool or instrument will automatically return to the molded shape having the at least one protrusion when at a temperature at or above the final transition temperature.

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: A method for producing blanks for endodontic instruments (1), endodontic instruments (1), and a delivery device. The method comprises the steps of providing at least one rod (2) and machining the at least one rod (2) by a wire erosion such that an erosion pattern (4) is applied to the at least one rod (2). The material eroded away from the at least one rod (2) at least partially deposits as a layer on the at least one rod (2). The layer of the re-deposited material has a surface hardness which substantially corresponds to the hardness of the material of the at least one rod (2).
