Patent

CA 2193121

The invention provides dental devices (including implants (40), abutments (12), bridges, screws (15), and orthodontic appliances (50, 51, 52)) that are fabricated from low modulus, biocompatible, non-toxic Ti-Nb-Zr alloys. The dental implants provide a biomaterial-to-bone interface that results in significant attachment between implant and bone. The implants may be supplied with a porous coating or macro-texture to further promote bone attachment and stabilization of the implant in the jaw bone. Other orthodontic appliances such as brackets (50) and wires (51) have improved elastic toughness and corrosion resistance so that they provide superior performance and corrosion characteristics.

Dispositifs dentaires (tels que des implants (40), des piliers (12), des ponts dentaires, des vis (15) et des appareils d'orthodontie (50, 51, 52)) fabriqués à partir d'allliages Ti-Nb-Zr non toxiques, biocompatibles à faible module. Les implants dentaires assurent une interface entre le biomatériau et l'os qui produit une fixation significative entre l'implant et l'os. Ces implants peuvent être dotés d'un revêtement poreux ou d'une macro-texture pour améliorer davantage la fixation sur l'os et la stabilisation de l'implant dans l'os de la mâchoire. D'autres appareils d'orthodontie tels que les attachements (50) et les fils (51) présentent une résistance élastique et une résistance à la corrosion renforcées de manière à posséder des caractéristiques de performance et de corrosion supérieures.
