Embodiment 1
[0044] 1) The extracted real isolated teeth were collected from the clinic. Here, the first premolar is taken as an example. The root canal system of the real isolated teeth was scanned by micro-CT. Based on the obtained original DICOM data, it was obtained by three-dimensional processing with Mimics software. Macroscopic and microscopic bionic 3D printing STL files, and STL file data for model reconstruction, submitted to high-precision 3D printers, using transparent resin materials to produce transparent resin tooth models. The root canal system of this transparent resin tooth model before root canal preparation was stained with blue dye.
[0045] 2) Fix the transparent resin tooth model with the root canal system dyed blue on the figure 1 On the abutment 5 of the root canal preparation effect detection device in the oral medicine teaching shown.
[0046] 3) Take the crown and buccal surface of the transparent resin tooth model as the frontal plane, adjust the focal length ...
Embodiment 2
[0058] 1) A commercially available transparent resin simulated root canal 4 with standardized overall length and curvature is selected, and the root canal system of the transparent resin simulated root canal 4 before root canal preparation is stained with blue dye.
[0059] 2) Fix the root canal system 4 with transparent resin dyed blue to simulate the root canal figure 1 On the abutment 5 of the root canal preparation effect detection device in the oral medicine teaching shown.
[0060] 3) Take the central axis plane that fully displays the root canal bending direction as the positive plane, adjust the focal length of the digital camera 2 to 30cm, and fix the focus of the transparent resin simulated root canal 4 in a direction perpendicular to the positive plane with the lens of the digital camera 2 Shooting, now the pointer 9 points to the position where the degree on the protractor 7 is 0°, and the frontal image A before the preparation is obtained 0 ,Such as figure 2 sh...
