  • Dental mill blank and support stub assembly
    Patent number: 6627327
    Abstract: A mill blank assembly for making a dental prosthesis includes a milling section and a support section. The support section is adapted to fit in a chuck or collect of a milling machine. One of the milling section and the support section includes a projection that extends into a recess of the other, in order to enhance the strength of the bond between the milling section and the support section. As a result, the completed assembly is less likely to fracture or become disassembled during the milling process.
