[0032] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the following is combined with the drawings and embodiment, and the utility model is further detailed.The specific embodiments described here are only used to explain the utility model, and are not used to limit the utility model.

[0033] Embodiment one

[0034] Please refer to Figures 1 to 4 A kind of tongue side orthodontic simulation practical operation training teaching aid, it includes:

[0035] Simulation skull 2, the upper end of the simulation skull 2 is provided with simulate oral cavity 21, the simulate oral cavity 21 is consistent with the shape of patient mouth opening state, simulation skull 2 simulates the body position of head in patient orthodontic operation process, i.e.

[0036] The inside of the simulate oral cavity 21 includes maxillary mounting surface 22 and mandibular mounting surface 23, maxillary mounting surface 22 and mandibular mounting surface 23 are opposite and are respectively inclined to be arranged, such as Figure 2The tooth model 3 is installed on the upper jaw mounting surface 22 and the lower jaw mounting surface 23, and the upper jaw mounting surface 22 and the lower jaw mounting surface 23 are hard surfaces, so as to support the tooth model 3. The tooth model 3 is a 3D printed tooth model, and the model data is selected from a clinical real case, so as to accurately reflect the original arrangement of the patient's teeth. Teeth are arranged in a specific order and angle in the oral cavity, and there is an accurate occlusion relationship between the upper and lower teeth. When the model is used to adapt to the simulation head model, the misalignment and twisting of the teeth can be truly displayed, and the influence of these problems on the occlusion function can be truly displayed. After a tooth model 3 is used for a period of time, a new model can be replaced, so as to facilitate students to use different tooth models with problems for training and improve the training effect. Before the 3D printed model is made, the data in the oral cavity needs to be accurately collected. In order to ensure that the accuracy of the scanning equipment is high enough, the resolution is at least 0.1 mm. After scanning is completed, professional three-dimensional modeling software is used to splice and optimize the scanning data, remove noise points, and ensure the accuracy of the data. In order to ensure the accuracy of the data, a data format suitable for 3D printing is selected in the early stage of design, so as to reduce the possibility of error caused by format conversion. When 3D printing is performed, an LCD light curing printer is selected. In the XY plane (horizontal plane), the feature size accuracy can reach about 0.1-0.3 mm. This means that when some models with fine structures or fine textures are printed, these details can be better restored.

[0037] Preferably, the tooth model 3 is provided with a first magnetic attraction member 4 on the surface away from the tooth, and the upper jaw mounting surface 22 and the lower jaw mounting surface 23 are respectively provided with a second magnetic attraction member 5 which is mutually attracted with the first magnetic attraction member 4. The back surface of the tooth model 3 is designed to be recessed for assembly of the first magnetic attraction member 4. By means of connection of the first magnetic attraction member 4 and the simulation skull, the first magnetic attraction member 4 and the second magnetic attraction member 5 use a magnetic plate, so as to ensure that the attraction force can reach 70 N, the connection with the simulation head model is firm, and the simulation head model is not easy to be loosened, so as to meet the practical training needs of users.

[0038] Preferably, the dental model 3 is also provided with a protruding limiting block 6 on the surface away from the teeth, and the upper jaw mounting surface 22 and the lower jaw mounting surface 23 are respectively provided with a limiting groove 7 matched with the limiting block 6. By arranging the limiting block 6 and the limiting groove 7, the stability of the dental model after installation is further improved, the sliding displacement of the magnetic connection part is avoided, and the practicability of the device is improved. When the dental model 3 needs to be installed, the limiting block 6 is first aligned in the limiting groove 7, then under the mutual attraction of the first magnetic attraction part 4 and the second magnetic attraction part 5, the limiting block 6 automatically enters the limiting groove 7 to realize clamping, and under the action of magnetic attraction, the dental model 3 is not easy to fall off, and when the dental model 3 is disassembled, it can be directly pulled out with a little force.

[0039] Preferably, the limiting block 6 and the limiting groove 7 are prismatic, so as to avoid relative rotation of the dental model 3 on the mounting surface.

[0040] Preferably, the surface of the first magnetic attraction part 4 is flush with the surface of the dental model 3, and the surface of the second magnetic attraction part 5 is flush with the surface of the upper jaw mounting surface 22 and the lower jaw mounting surface 23, so that the connection of the flush surfaces is more stable.

[0043] Preferably, one side of the lower end of the simulation skull 2 is connected to one end of the support platform 1 through a connecting frame 13.

Through repeated training in a new perspective and posture, students can master the use of mouth mirrors, needle holders, probes and other instruments, and efficiently master the operation skills of this technology. It should be noted that the 3D printed dental model: 1. Reflects the "mildly crowded teeth" malocclusion. 2. Through the steps of digital tooth arrangement, digital bracket design, and machine hand arch wire bending, an indirect adhesive tray for lingual correction is made. 3.
