  • Patent number: 9814548
    Abstract: The present invention relates to a three-dimensional oral cavity scan device for a digital impression that obtains a three-dimensional image by processing a two-dimensional image acquired by photographing a three-dimensional subject in an oral cavity. The device includes: a pattern mask converting parallel light incident thereto into structured light; a piezoelectric plate where a mechanical vibration is generated on a surface thereof by an AC voltage applied thereto; and a power supply unit applying the AC voltage to the piezoelectric plate, wherein the piezoelectric plate moves the pattern mask in a longitudinal direction of the piezoelectric plate by using the mechanical vibration. The device can reduce noise and vibration by moving the pattern mask with an electrical method. In addition, the device can accurately measure depth of teeth by electrically controlling a focal length of structured light projected on the teeth.
