Patent ID: 8520925

Claim:
A three-dimensional and temporal measuring device through optical color imprint usable in the dental field, wherein the device for taking three-dimensional dental pictures does not use structured light projection, the device comprising: a stereo camera comprised of at least two CCD or CMOS color sensors in a predetermined position defining, because of resetting speed, the reading speed, thus the speed of taking successive imprints, and permitting a static or dynamic reading; an optical system of fixed and preset focal length permitting to transmit to the sensors, without distortion, data displayed on the operating field; an LED lighting system for illuminating the area of taking an imprint; and an electronic system located behind or proximate each of the sensors, ensuring control thereof control of LEDs illuminating the area of taking an imprint, wherein said electronic system comprises: a central control unit capable of collecting, storing and organizing the data captured by said sensors; and a card for controlling said LEDs, depending on said central unit, wherein said sensors are distributed over a whole or part of a dental arch in order to make an imprint in one single exposure, avoiding clinical scanning of the arch, said sensors being arranged in an optical imprint tray permitting to capture the complete arch in one single exposure.
