s12, manufacturing a tooth socket, namely placing a membrane for manufacturing the tooth socket on the tooth mould, and preparing the tooth socket on the tooth mould by using a heating vacuum forming process;
s13, arranging concave points on the dental model, and drilling the concave points at the corresponding dental model positions of the teeth of the patient needing stress application according to the tooth correction scheme;
s14, manufacturing a convex structure on the tooth socket, sleeving the tooth socket on the tooth mould provided with the concave points, and heating and pushing the part, corresponding to the concave points, of the tooth socket by using the heating probe so that the part, corresponding to the concave points, of the tooth socket protrudes towards the direction close to the teeth to form the convex structure.
8. The method of claim 7, wherein the contour of the concave points of the dental cast is circular, rectangular or irregular, and the contour of the convex structures is correspondingly circular, rectangular or irregular.
9. The method for manufacturing the stress application type tooth correcting device according to claim 7, wherein the height of the convex structure of the mouthpiece protruding towards the direction of the teeth is determined according to the tooth correcting scheme, the concave points with the corresponding depth are drilled at the corresponding positions of the dental cast, the mouthpiece is sleeved on the dental cast provided with the concave points, and the probe is heated and pushed against the part of the mouthpiece corresponding to the concave points to the bottom of the concave points to form the convex structure with the height matched with the depth of the concave points, so that the convex structure has the set correcting force on the teeth.
10. The method for manufacturing the stressing-type orthodontic device of claim 7, wherein the tip of the heating probe is matched with the concave point, and the heating probe is used for heating and pushing the part of the mouthpiece corresponding to the concave point to form a convex structure matched with the concave point.
