Optical coherence tomography image generation device and dental CADCAM device

A dental CAD/CAM device comprising:

• a tooth three-dimensional information measurer that irradiates a tooth with measuring laser light to measure a tooth surface shape and tooth interior as tooth three-dimensional information, and visualizes the tooth three-dimensional information to display a tooth image on a display device;
• a laser cutter that irradiates the tooth with cutting laser light to cut the tooth;
• a two-dimensional scanning mechanism that scans laser light, which is either the measuring laser light and/or the cutting laser light, in two dimensions;
• a probe that includes the two-dimensional scanning mechanism, and outputs the laser light, which has passed through the two-dimensional scanning mechanism, from a tip thereof;
• an optical path coaxializer that coaxializes an optical path of the measuring laser light entering the two-dimensional scanning mechanism with an optical path of the cutting laser light entering the two-dimensional scanning mechanism;
• a tooth fixer that fixes the probe to the tooth;
• a restoration designer that designs dental restorations based on the tooth three-dimensional information measured by the tooth three-dimensional information measurer;
• and
• a restoration producer that produces dental restorations based on data obtained from the restoration designer.
