Abstract: An intra-oral laser digitizer system provides a three-dimensional visual image of a real-world object such as a dental item through a laser digitization. The laser digitizer captures an image of the object by scanning multiple portions of the object in an exposure period. The intra-oral digitizer may be inserted into an oral cavity (in vivo) to capture an image of a dental item such as a tooth, multiple teeth or dentition. The captured image is processed to generate the three-dimension visual image.

Abstract: The improved milling machine makes use of individually controlled x-axis, y-axis, and z-axis carriages. These carriages provide positive and precise control of the position of the cutting tools and the blank to be cut. A tool changer allows the tools to be changed to accommodate other materials. A camera is used to detect wear on the tools.

Abstract: An improved milling machine makes use of individually controlled x-axis, y-axis, and z-axis carriages. These carriages provide positive and precise control of the position of the cutting tools and the blank to be cut. The tools are located in spindles that are moved in the x-axis. A work piece or blank is manipulated in the y-axis and the z-axis. The tools are offset in the x-axis. Lights on a work space door are used to signal the condition of the mill machine and the milling operation. A tool changer allows the tools to be changed to accommodate other materials. A camera or other sensor is used to detect the location and wear on the tools.
