A method of manufacturing an implant is disclosed. The method includes preparing a wax template assembly based upon anatomical characteristics of an implantation site. Post formation of the template assembly, a lamination layer is provided over the template assembly resulting in a laminated template assembly. The lamination layer is composed of at least one polymer dissolved in one or more solvents. One or more coating layers of a pre-defined coating material are provided over the laminated template assembly to prepare a mold. The mold may then be sand-rained to form a sand coated mold. The sand coated mold may be de-waxed and baked for melting out the template assembly to form a de-waxed mold. A casting material is then poured over the de-waxed mold to form a casted mold which is cooled and solidified to form a casted implant which is further heat treated and finished to form the implant.

Provided are: an alloy member that is excellent in homogeneity of both the alloy composition and microstructure and excellent in shape controllability and includes a high entropy alloy having high mechanical properties and high corrosion resistance, a process for producing the same, and a product including the alloy member. In the present invention, the alloy member having a chemical composition comprising elements of Co, Cr, Fe, Ni, and Ti each in an amount within a range of 5 atomic % or more and 35 atomic % or less and Mo in an amount within a range of more than 0 atomic % and 8 atomic % or less, the reminder consisting of unavoidable impurities, wherein ultrafine grains having an average grain diameter of 100 nm or less are dispersed and precipitated in a parent phase crystal.

A dental tool or instrument having a shank located adjacent a first end thereof and a working area located adjacent an opposite second end. At least one elongate cut is formed along the working area and a memorized shape, having at least one protrusion, is formed in the working area. The dental tool or instrument is manufactured from a nitinol wire which initially has a transition temperature that is below room temperature, while the dental tool or instrument, following manufacture, has a final transition temperature of about 90.5±4 degrees Fahrenheit (i.e., 32.5±3 degrees Celsius). When the dental tool or instrument is at a temperature below its final transition temperature, the dental tool instrument is moldable to facilitate insertion into a root canal, but as soon as the dental tool or instrument is at or above the final transition temperature, the dental tool instrument automatically adopts the memorized shape.
