determining a wax filling range according to the digital intraoral model, and shifting the front teeth and the front molar area to the labial cheek side by a first preset distance, and shifting the molar area to the buccal side by a second preset distance to obtain a wax filling model; wherein the left and right ends of the wax-filled range terminate distally in the first molar, the upper and lower edges of the wax-filled range extending to the labial cheek mucosa reverse fold line, except for the maxillary incisors;
carrying out smoothing treatment on the surface of the wax-filled model;
selecting a manufacturing range of a vestibular shield correction model from the wax-filled model, wherein the manufacturing range of the vestibular shield correction model is the same as the wax-filled range;
shifting the selected vestibular shield patch fairing boundary to the cheek side direction by a third preset distance;
an air guide mechanism is arranged on the vestibular shield patch;
moving the created circular ring to the incisor of the labial side of the vestibular shield, and carrying out combined Boolean operation on the circular ring and the vestibular shield facing provided with the air guide mechanism to obtain a vestibular shield correction model;
and printing the vestibular shield correction model through 3D printing equipment to obtain the vestibular shield correction device.
2. The method of digital design of a vestibular shield appliance according to claim 1, wherein the step of providing an air guide mechanism on the vestibular shield facial mask comprises:
creating at least one columnar body on the vestibular shield patch to form an air guide mechanism on the vestibular shield patch;
moving the columnar body to a distal midcut end of the maxillary incisors;
and carrying out Boolean subtraction operation on the vestibular shield patch provided with the air guide mechanism and the columnar body.
3. The digital design method of the vestibular shield appliance according to claim 2, wherein the columnar body is a cylinder, the diameter of the cylinder is 3mm-4mm, and the height of the cylinder is 4mm-6mm.
4. The digital design method of the vestibular shield appliance according to claim 3, wherein the air guide mechanism is a through hole, and the inner diameter of the through hole is 3mm-4mm.
5. The method for digitized design of a vestibular shield appliance according to claim 4, wherein the distance between the two through holes and the anterior teeth is equal.
6. The digital design method of a vestibular shield appliance according to any one of claims 1 to 5, further comprising, after the step of printing the vestibular shield appliance model by a 3D printing device:
and grinding and polishing the vestibular shield appliance.
7. The method of digital design of a vestibular shield appliance according to any one of claims 1 to 5, wherein the scanning range of the intraoral scanner includes data of lips, buccal teeth, and mucous membrane.
8. The digital design method of a vestibular shield appliance according to any one of claims 1 to 5, wherein the first predetermined distance is 1.8mm-2.3mm and the second predetermined distance is 2.5mm-3.5mm.
9. The digital design method for a vestibular shield appliance according to any one of claims 1 to 5, wherein the third predetermined distance is 1.8mm to 2.3mm.
10. The digital design method of a vestibular shield appliance according to any one of claims 1 to 5, wherein the outer diameter of the ring is 9mm-11mm and the inner diameter of the ring is 7mm-9mm.
