Abstract
Dental arches of single-crystal shape memory alloys, methods of fabrication and apparatus for fabrication. The methods include drawing a single crystal of a shape memory alloy from a melt of the alloy. This is followed by heating, forming, and quenching the crystal sufficiently rapid to limit the formation of alloy precipitates to an amount which retains hyperelastic composition and properties of the crystal.
Claims9
A dental arch comprising a hyperelastic, single-crystal shape memory alloy, the dental arch having an elongate, shape-set curved length in an unstressed state that is configured to fit within a human mouth.
