    摘要： A system comprises a dental tray comprising an array of cameras, wherein each camera of the first array of cameras has a fixed position and orientation relative to one or more other camera of the array of cameras. The system further comprises a processing device to receive a plurality of images generated by the array of cameras, stitch the plurality of images together based on calibration data specifying predetermined image stitching parameters for combining the plurality of images, wherein the predetermined image stitching parameters are based on predetermined fixed relative positions and orientations of cameras from the array of cameras, and generate a three-dimensional model of a plurality of teeth based on the stitched plurality of images.

    摘要： A system comprises a dental tray comprising an array of fixed focus cameras, wherein each fixed focus camera of the first array of fixed focus cameras has a fixed position and orientation relative to one or more other fixed focus camera of the array of fixed focus cameras. The system further comprises a processing device to receive a plurality of images generated by the array of fixed focus cameras, stitch the plurality of images together based on calibration data specifying predetermined image stitching parameters for combining the plurality of images, wherein the predetermined image stitching parameters are based on predetermined fixed relative positions and orientations of fixed focus cameras from the array of fixed focus cameras, and generate a three-dimensional model of a plurality of teeth based on the stitched plurality of images.

    摘要： A mouth mirror apparatus includes a carrier seat that has first and second receiving spaces and multiple outlet passages embedded in a surrounding wall and intercommunicating the first and second receiving spaces. The mouth mirror apparatus further includes a handle grip cooperating with the carrier seat to define an air inlet passage that communicates with the second receiving space, a mirror body rotatably disposed in the first receiving space, and an impeller connected to the mirror body and driven by air which flows from the air inlet passage. Through combination of the mirror body, the impeller, and the arrangement of the air outlet passages, the mouth mirror apparatus can direct air current to render different functions.

    摘要： A dental instrument and method for imaging the three-dimensional topography of one or more teeth in the oral cavity of an individual is provided. The instrument includes a probe insertable into the oral cavity to receive the image of these surfaces which can then be processed. Combined with the probe is an auxiliary which projects an air stream toward the surface to be imaged by the probe and acts to evaporate and remove from these surfaces a liquid film coating formed by saliva and other fluids present in the oral cavity, to render these surfaces dry and to enhance their reflectivity and in doing so, provide clearer images.
