The reinforcing ridge 10 is completely fixed on the surface of the appliance body 101 away from the cavity S, and when the shell-shaped dental appliance 100 is worn to the tooth T to be corrected, the reinforcing ridge 10 applies force to the tooth T to be corrected through the appliance body 101.
Here, "completely fixed" means that one side of the reinforcing ridge 10 close to the appliance body 101 is fixed to the appliance body 101, the reinforcing ridge 10 is directly provided at the surface of the appliance body 101, when the shell-shaped dental appliance 100 is not worn to the tooth T to be corrected, the reinforcing ridge 10 does not come into contact with the tooth T to be corrected in advance, when the shell-shaped dental appliance 100 is worn to the tooth T to be corrected, the reinforcing ridge 10 is fitted to the tooth T to be corrected together with the shell-shaped dental appliance 100, and at the same time, the reinforcing ridge 10 applies force to the tooth T to be corrected through the appliance body 101.
That is to say, different from the prior art in which the attachment is directly adhered to the tooth, the reinforcing ridge 10 of the present embodiment is fixed to the surface of the appliance body 101, and since the appliance body 101 and the tooth T to be corrected are tightly fitted to each other, and the appliance body 101 applies force to the tooth T to be corrected, the reinforcing ridge 10 fixed to the appliance body 101 may also apply force to the tooth T to be corrected through the appliance body 101.
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 shell-shaped dental instrument 100 of the present embodiment directly includes the reinforcing ridges 10, the arrangement of the reinforcing ridges 10 can improve the local strength and rigidity of the shell-shaped dental instrument 100, and reduce the moment, when the reinforcing ridges 10 of the shell-shaped dental instrument 100 apply force to the tooth T to be corrected, the effect of protecting the tooth T to be corrected can be achieved, for example, the 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 thus a better dental arch form is obtained.
In addition, the shell-shaped dental instrument 100 of the present embodiment directly includes the reinforcing ridge 10, and the patient can directly wear the shell-shaped dental instrument 100 to achieve the above effects, which is convenient to use and has better user experience.
It should be noted that, in the example of performing the correction by using the shell-shaped dental appliance 100, the correction generally needs to be divided into a plurality of successive stages (for example, 20 to 40 successive stages), each stage corresponds to one shell-shaped dental appliance 100, the reinforcing ridges 10 may be optionally added or not added according to specific requirements of different stages, and the addition parameters of the reinforcing ridges 10 may be freely designed according to the specific requirements of different stages, where the addition parameters include the number, position, form, and the like of the reinforcing ridges 10.
In the present embodiment, the reinforcing ridge 10 has a first thickness in the direction Z in which the buccal surface A3 of the appliance body 101 faces the lingual surface a4, and the maximum value of the first thickness is in the range of 0.2mm to 2 mm.

In addition, in some embodiments, due to the presence of tooth extraction vacancies, gaps or other conditions, not the entire fixation area 1011 is in full contact with the force-bearing area T1, but only a portion of the area of the fixation area 1011 is disposed proximate the force-bearing area T1, although in other embodiments all of the area of the fixation area 1011 may be disposed proximate the force-bearing area T1, as may be desired.
Here, the tooth extraction vacancy is an extraction region, and the gap may be a gap between adjacent teeth, for example.

It can be seen that, no matter the reinforcing ridge 10 is formed in advance or the reinforcing ridge 10 is formed by filling and curing, the reinforcing ridge 10 can be completely matched with the appliance body 101, that is, the shell-shaped dental appliance 100 with the appropriate reinforcing ridge 10 can be generated according to different tooth forms and positions in the embodiment, and the part of the appliance body 101 with the reinforcing ridge 10 can be ensured to be stably contacted with the tooth T to be corrected, so that the effects of reinforcing the local structure of the shell-shaped dental appliance 100 and reducing the moment are achieved.
In other embodiments, the reinforcing ridge 10 may be integrally formed with the appliance body 101.
For example, the reinforcing ridge 10 may be formed from the same material as the appliance body 101, and the reinforcing ridge 10 may be formed by locally thickening the appliance body 101.
