    摘要: A milling machine for a dental item comprises a six (6) axis motion system. A workpiece is fixed in space. Each of a pair of opposed tool spindles operates in 3 DOF, with an x-axis (laterally, left or right) being along an axis of each working tool, a rotational (theta (θ)) axis (rotationally in or out), and a z-axis (up or down). On each respective side of the block, the x-axis rides on a θ-axis, and the θ-axis rides on the z-axis. Each z-axis supports a first carriage adapted to move up or down along the z-axis, and the first carriage supports a motor having a shaft. The shaft's rotational axis is the θ-axis. A second carriage is mounted on the shaft for rotation about the θ-axis. A spindle assembly is mounted on the second carriage for lateral (left or right) movement along the x-axis carried by the θ-axis.

    摘要: 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.

    摘要: A digitized image of an object may include representations of portions of the object that are obscured, occluded or otherwise unobservable. The image may be a multi-dimensional visual representation of dentition. Characteristics of the dentition and its surfaces, contours, and shape may be determined and/or analyzed. A light may be directed toward and reflected from the dentition. The reflected light may be combined with a reference to determine characteristics of the dentition, including obscured areas such as subgingival tissue.
