  • Hydroxyapatite prosthesis coatings
    Patent number: 5279831
    Abstract: Methods and compositions are provided for coating a substrate with a strongly adherent hydroxyapatite coating, which allows for ingrowth of natural bone and strong bonding between the coating and the substrate. The procedure provides for repetitive coatings at varying concentrations of coating forming reagents, where the highest concentration is used initially. The coating has particular application for prostheses, where porous areas of the prostheses are completely coated with a thin sturdy coating of hydroxyapatite.
    Type: Grant
    Filed: August 21, 1992
    Date of Patent: January 18, 1994
    Assignee: Norian Corporation
    Inventors: Brent R. Constantz, Gary C. Osaka
