Abstract: A technique to enable an existing monochrome camera in an intra-oral scanner to capture color images without making hardware changes to the camera. This operation is achieved by retrofitting a “tip” assembly of the scanner with red, green and blue light emitting diodes (LEDs), and then driving those diodes to illuminate the scene being captured by the scanner. Electronics in or associated with the scanner are operative to synchronize the LEDs to the frame capture of the monochrome camera in the device. A color image is created by combining the red-, green- and blue-illuminated images. Thus, color imagery is created from a monochrome camera and, in particular, by illuminating the screen with specific colors while the camera captures images. In this manner, single colored images are captured and combined into full color images. The system captures the color images with full resolution and sensitivity, thus producing higher quality full color images.

Abstract: An intra-oral scanning device includes a light source and an optical system, and communicates with a display system. The device captures images of an object of interest, e.g., patient teeth or associated anatomy, by projecting the light source as a first series of frames, and a second series of frames. The first series of frames projects first pattern data, and the second series of frames projects second data. The second series of frames are interleaved between frames in the first series of frames. The frames in the first series are partially-illuminated and are used to capture data for a 3D model. The frames in the second series are preferably fully-illuminated and are used to generate a live preview of the object. By displaying the live preview frames in juxtaposition to the 3D model, the operator is provided with visual feedback of the object.

Abstract: 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 (?)) 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 ?-axis, and the ?-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 ?-axis. A second carriage is mounted on the shaft for rotation about the ?-axis. A spindle assembly is mounted on the second carriage for lateral (left or right) movement along the x-axis carried by the ?-axis.

Abstract: A mill blank mandrel may rigidly secure machinable material for a machining process. The mandrel may be freely and easily inserted in a corresponding mandrel socket and secured without the use of a tool. The mandrel may be detected and verified when inserted in the mandrel socket.

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.
