  • Calcium phosphate ceramics for bone tissue calcification enhancement
    Patent number: 5171326
    Abstract: Improved ceramics which promote bone ingrowth are disclosed. The coating of the present invention consists essentially of oxyhydroxyapatite, and alpha- and beta-tricalcium phosphate. Methods of making and using the ceramics are also disclosed. The present invention uses a microscopically powdered form of calcium-phosphate materials and electrophoretic deposition to create ceramics having significantly higher dissolution rates than previous materials. By agitating the electrophoretic solution, agglomeration is prevented and a uniform coating is achieved. Thus, the present invention presents both improved ceramic materials and novel methods of depositing them uniformly upon metal surfaces, such as titanium wire mesh.
    Type: Grant
    Filed: February 20, 1992
    Date of Patent: December 15, 1992
    Assignee: Trustees of the University of Pennsylvania
    Inventors: Paul Ducheyne, John Cuckler, Shulamit Radin
