Abstract:

DESCRIPTION (provided by applicant): The overall objective of the proposed SBIR program is to design, manufacture, and evaluate a high-speed, low-damage, machining center for fabrication of Dental restorations in the Dental office or laboratory. This new m ethod for fabrication of Dental restorations based on computer aided design and computer aided manufacturing (CAD/CAM) has revolutionized Dentistry during the past decade. These systems are currently used to fabricate ceramic crowns and other Dental struct ures. While the CAD/CAM restorations have proven to be more reliable than those fabricated by traditional methods, the 10-year survival rate is still less than 90%. Furthermore, these systems cannot be used for machining of restorations made from harder ce ramics such as zirconia. The proposed machining center will be designed with an innovative integrated air-driven, high-speed, precision spindle/motor assembly to allow high machining rates while ensuring low potential for machining damage: thus, enabling r apid fabrication of low-damage Dental restorations by machining. Phase I plan includes design, fabrication, and testing of an air-driven, high-speed, motor-spindle assembly operating at ultra-high speeds; and machining data obtained on two machinable Denta l ceramics and partially stabilized zirconia in a full factorial design of experiments showing reduced machining damage as compared to the current practice. The data on machining rates and surface/subsurface damage will be compared with similar data alread y published by the applicant from a previous NIDCR Program Project Grant on machining with a high-speed Dental handpiece. The aim of these experiments is to test the hypothesis that high-speed machining reduces the propensity for generation of machining da mage. While high-speed machining has been implemented for grinding of industrial ceramics, including zirconia, such an approach is yet to be considered for Dental CAD/CAM systems.
