The illumination intensity of the LED light source can be adjusted according to the pre-set optimal illumination intensity threshold of the scanning area and the real-time detected illumination intensity of the scanning area, so as to ensure that the illumination intensity of the scanning area is stably and consistently maintained at the optimal illumination intensity value during the scanning process, thereby improving the scanning accuracy of the oral cavity scanner. The power module 6 supplies power to each part of the device.

[0019] The whole bracket 1 is a hollow structure for passing the related wires. The LED light source 2 and the illumination intensity sensor 3 are embedded on the lower side of the front part of the whole bracket 1. The LED light source 2 is located beside the scanning window of the oral cavity scanner. The illumination intensity sensor 3 is located behind the LED light source.

The power supply line of the power module 6 is passed through the hollow cavity of the whole bracket 1 and is electrically connected with the LED light source 2, the illumination intensity sensor 3, the liquid crystal display 4 and the master control unit 5 respectively, so as to supply power to each part of the device.

[0020] In the embodiment, the whole bracket 1 comprises left and right extension frames and front and rear connecting frames. The left and right extension frames are respectively arranged on the left and right sides of the oral scanner and respectively adapted to the shapes of the left and right sides of the oral scanner to fit the oral scanner. The front and rear connecting frames are both inverted U-shaped structures. The front connecting frame is located in the middle of the whole bracket and its left and right lower ends are respectively connected to the left and right extension frames. The rear connecting frame is located in the rear of the whole bracket and its left and right lower ends are respectively connected to the left and right extension frames.
