  • Apparatus and method for machining a prosthetic tooth restoration
    Patent number: 6641340
    Abstract: The present invention is directed to enhancing the accuracy with which tooth restorations are performed, including the manner by which a tooth is prepared and fit with a dental prosthetic, such as a crown or bridge. Further, the present invention is directed to reducing the skill-dependent tasks associated with tooth restoration, including root canals, while at the same time, improving the precision with which these procedures are performed and by aesthetics of the prosthetic. By improving the accuracy of restoration procedures, any need to repeat these procedures for a given patient can be eliminated and patient comfort can be improved. In addition, by improving the precision with which a prosthetic is prepared for attachment to the prepared tooth of a patient, and/or fit to patient, durability and longevity of the prosthetic are improved.

  • Apparatus and method for producing a dental prosthetic with a device having a linear rotary bearing
    Patent number: 6527550
    Abstract: The present invention is directed to enhancing the accuracy with which tooth restorations are machined, using a device which can accurately copy mill a dental prosthetic blank from a previously formed dental prosthetic model, and which can closely replicate the feel of a dental tool to which dentists are accustomed. The device uses a tool supported on a linear rotary axis to mill the dental prosthetic blank. In addition, exemplary embodiments are directed to the preparation of a hybrid dental prosthetic blank which can be easily machined.
