  • Patent number: 6403212
    Abstract: A moldable dental material composition comprising high-fusing temperature metal particles, a volatile binder, preferably in a concentration of above at least twenty percent (20%) of the material composition, and finely divided carbonaceous particles, preferably of activated carbon. The high-fusing temperature metal particles should have an irregular, nonspherical geometry and a thin cross-sectional average thickness. The moldable dental composition may also contain low-fusing temperature metal particles for enhanced wetting of the high-fusing metal particles during heat treatment at a heat-treatment temperature which will melt the binder and substantially melt the low-fusing metal particles, if present. Heat treatment forms a porous metal structure having a capillary network of voids and a high void volume.
    Type: Grant
    Filed: July 25, 1994
    Date of Patent: June 11, 2002
