The reinforcing ridge 10 includes a receiving cavity 11 protruding in a direction away from the cavity S, and a filling part 12 fixed in the receiving cavity 11, and the filling part 12 contacts the tooth T to be corrected when the orthodontic appliance 100 is worn to the tooth T to be corrected.

Specifically, when orthodontic appliance 100 is not worn to treating when correcting tooth T, filling portion 12 is fixed in and holds chamber 11, and filling portion 12 can not go in advance to contact and treat and correct tooth T, wears to treating when correcting tooth T when orthodontic appliance 100, and filling portion 12 along with orthodontic appliance 100 cooperates to treating and corrects tooth T together, and simultaneously, filling portion 12 contacts and treats and correct tooth T.

That is to say, unlike the prior art in which the attachment is directly bonded to the tooth, the filling portion 12 of the present embodiment is fixed in the receiving cavity 11 of the orthodontic appliance 100, and by the rational design of the filling portion 12, the filling portion 12 can contact the tooth T to be corrected when the orthodontic appliance 100 is worn, and the filling portion 12 can apply force to the tooth T to be corrected at this time.

In addition, the appliance body 101 has a first height H between the occlusal surface A1 and the gingival end A2, and the reinforcing ridge 10 is located between the gingival end A2 and the midpoint O of the first height H.

Here, a buccal surface A3 near the buccal side and a lingual surface a4 near the lingual side are formed between the occlusal surface a1 and the gingival end a2 of the appliance body 101, and the reinforcing ridge 10 is located on the buccal surface A3 and/or the lingual surface a4 of the appliance body 101.

Taking buccal surface A3 as an example, first height H corresponds to the length of buccal surface A3 in the direction X from occlusal surface a1 to gingival end a2, and the entirety of reinforcing ridge 10 is located adjacent to gingival end a2, and "reinforcing ridge 10 is located between gingival end a2 and midpoint O of first height H" means that entirety of reinforcing ridge 10 is located in the lower half of buccal surface A3 near gingival end a2, i.e., the highest point of reinforcing ridge 10 near occlusal surface a1 does not exceed the midline L of buccal surface A3, which extends in the mesial-distal direction Y.

The orthodontic appliance 100 of the embodiment directly comprises the reinforcing ridge 10, the local strength and rigidity of the orthodontic appliance 100 can be improved by the arrangement of the reinforcing ridge 10, and the moment is reduced, when the filling part 12 of the orthodontic appliance 100 applies force to the tooth T to be corrected, the effect of protecting the tooth T to be corrected can be achieved, for example, an anchorage tooth is protected, or unnecessary movement of the tooth T to be corrected is reduced, accurate control of movement of the tooth T to be corrected is achieved, and therefore a better dental arch form is obtained.

In addition, the orthodontic appliance 100 of the present embodiment directly includes the reinforcing ridge 10, and the patient can achieve the above effects by directly wearing the orthodontic appliance 100, which is convenient to use and has better user experience.
