Patent attributes
The present invention relates to a three-dimensional oral scanner. In particular, the present invention comprises: a case which can be drawn in and out of an oral cavity and has an opening formed in a manner such that the shape of the inside of the oral cavity (hereinafter, abbreviated as “image”) is introduced to the inside in the form of light through one end thereof; a pair of lenses disposed inside the case and spaced apart from each other in the width direction of the case so as to pass light incident from one end of the case in different paths; a pair of imaging boards having an imaging sensor for imaging the respective lights transmitted through the pair of lenses and disposed in close contact with a widthwise side wall and the other widthwise side wall of the case; and a pair of light path changing units arranged to change the respective paths of the lights transmitted through the pair of lenses toward the imaging board. As such, it is possible to manufacture an oral scanner to be slim overall, while providing the advantage of maximizing the utilization of the internal space of the oral scanner.
