  • Dental mill blank assembly
    Patent number: 7214435
    Abstract: A mill blank assembly for a dental prosthesis includes a milling section and a support section for supporting the assembly in a milling machine. In certain embodiments, the milling section is adhesively bonded to the support section by a direct chemical bond that provides enhanced resistance to unintentional detachment of the milling section from the support section during a subsequent machining operation. Optionally, the support section includes a passageway that receives a quantity of flowable dental restorative material used to make the milling section, such that the restorative material that is located in the passageway provides additional resistance when hardened to unintentional detachment of the milling section from the support section.
    Type: Grant
    Filed: October 3, 2003
    Date of Patent: May 8, 2007
    Assignee: 3M Innovative Properties Company
