Title: CAD/CAM MILLING PROCESS FOR THE FABRICATION OF DENTAL DEVICES
Abstract:
A method for fabricating a dental device using an improved milling technique is provided. The method uses a process in which the desired coping is milled from blanks made of a mix of metal powders and a polymer binder prior to densification. The step of densification incorporates debinding and sintering with or without infiltration. The method takes advantage of the advances in CAD/CAM technology to compensate for the shrinkage inherent when using mixes of metal and polymer powder to ensure proper dimensions in the final dental device.
