It will be further understood that terms, such as those defined in commonly used dictionaries, should be interpreted as having a meaning that is consistent with their meaning in the context of the prior art and will not be interpreted in an idealized or overly formal sense unless expressly so defined herein.

Referring to fig. 1, a bracket-less invisible appliance is shown in a cross-sectional view of an upper shell of a shell at the location of a tooth 2 to be reshaped. In this embodiment, before the bracket-free invisible appliance is used for orthopedic patients, one of the upper teeth is moved backwards due to bad habits, and the dental caries caused by the backward movement of the teeth can increase the pain of the correction process when excessive tooth correction force is applied to the dental caries. Therefore, the bracket-free invisible appliance of the embodiment is adopted for correction.

The bracket-free invisible appliance should include a complete shell including a lower shell and an upper shell, the upper and lower shells having upper and lower sockets therein which are fitted with teeth of a patient, the lower socket fitting a mandibular teeth form of the wearer to insert and positionally fix the mandibular teeth of the wearer, and the upper socket fitting an maxillary teeth form of the wearer with a margin to insert and advance or retreat the maxillary teeth by a predetermined distance to correct the jawbone. Considering that the patient only needs to correct one tooth, the lower tooth socket can be not prepared or can be selectively worn after being prepared so as to improve the aesthetic degree; the upper tooth socket comprising the teeth to be corrected can be directly prepared, and the upper tooth socket can be worn to correct the teeth after being prepared and can also be taken down automatically according to the situation.

The upper tooth socket and the lower tooth socket of the tooth socket body are obtained by scanning the jaw part of a patient through optical equipment 3D to obtain a tooth jaw model of the patient, performing inversion according to the tooth jaw model and formulating an orthopedic scheme, wherein transparent polyether ketone (PEKK) with relatively small elastic modulus is used as a material for performing hot press molding on an inverted mold body of the tooth jaw model according to the orthopedic scheme, spaces are reserved on two sides of the position of a tooth 2 to be orthopedic during molding, an orthopedic seat 3 with a bulging convex part in the front and the rear is obtained, and a cavity with the size larger than the tooth 2 to be orthopedic is molded on the inner side of the orthopedic seat 3 to serve as an orthopedic groove. In the present embodiment, the thickness of the upper shell except for the position of the orthopedic base 3 is uniform, so that the upper shell has better comfort during the wearing process of the patient; the thickness thereof may be selected according to the material properties or the distortion state of the tooth 2 to be corrected, and the softer the material, the thicker the thickness should be, and the more severe the distortion of the tooth 2 to be corrected, the thicker the thickness.
