As shown in fig. 1 to 3, the present embodiment provides an orthodontic attachment for abutment on a tooth 1 and for cooperation with a mating orthodontic device 3, the orthodontic attachment 2 including an attachment body 21 for receiving an occlusal pressure of the tooth 1 located opposite to a molar region, the attachment body 21 having a first abutment surface 21a provided at one end thereof, the first abutment surface 21a being capable of abutment with the tooth 1, the attachment body 21 having a second abutment surface 21b provided opposite to the first abutment surface 21a, the second abutment surface 21b being capable of abutment with the orthodontic device 3.

The first abutting surface 21a of the orthodontic accessory 2 abuts against the teeth 1 in the molar area, the second abutting surface 21b abuts against the orthodontic device 3, the accessory body 21 plays a supporting role, when the orthodontic device 3 is worn by a patient, the teeth opposite to the molar area are separated by the orthodontic accessory, namely, occlusion of the rear teeth is raised, occlusion of the front teeth is opened, and occlusion wounds in the orthodontic process can be avoided when the inverse jaw of the teeth is corrected.

As shown in fig. 1-3, the present embodiment is described in detail below as an orthodontic attachment for abutment on teeth 1 and for cooperation with a mating orthodontic appliance 3 to avoid bite trauma during the orthodontic treatment when the inverse jaw of the teeth is corrected. Specifically, the orthodontic attachment 2 includes an attachment body 21 to be able to receive the occlusal pressure of the teeth 1 located opposite to the molar region; in this embodiment, the attachment body 21 is made of a polymer material, such as a resin material, so as to better fit with the teeth 1, thereby increasing the applicability of the orthodontic attachment 2 to the oral cavity; meanwhile, the self strength can be increased, and damage is avoided. The orthodontic attachment 2 in the present embodiment may be injection molded or 3D printed. The attachment body 21 comprises a first abutment surface 21a provided at a first end thereof, the first abutment surface 21a being intended for abutment contact with the tooth 1, typically in a paste-like arrangement; further, the area of the first abutting surface 21a is smaller than the area of the occlusal surface of the tooth 1 in the tooth grinding area abutting against the first abutting surface, so that the accessory body 21 is prevented from protruding out of the tooth 1 in the correcting process, the accessory body 21 is prevented from touching the oral cavity to cause friction damage, and on the other hand, the tooth correcting device 3 is prevented from being worn in the using process, and the tooth correcting device 3 is prevented from being not attached to the tooth 1. Further, the first abutment surface 21a is an ellipse, wherein the major axis of the ellipse is 2-5.5mm, the minor axis of the ellipse is 1.5-3.0mm, in this embodiment, the major axis is 5.5mm, the minor axis is 3.0, the applicability of the first abutment surface 21a can be further improved by adopting the ellipse, abrasion caused by protrusion of the edge angle is avoided, and the above range can be better suitable for most tooth scenes. In other embodiments, the first contact surface 21a may be other flat surfaces, and the contact area may be increased, so as to disperse the engagement pressure, such as a rectangle, a circle, or the like. The attachment body 21 has a second abutment surface 21b opposite to the first abutment surface 21a, the second abutment surface 21b is capable of abutting against the dental appliance 3, and the second abutment surface 21b is configured as an arc surface to avoid damage when abutting against the dental appliance 3. Further, the circumferential surface of the attachment body 21 is a cambered surface, so as to be matched with the tooth correcting device 3 to avoid hard friction and damage. The height of the accessory body 21 is 1.0-3.0mm, in this embodiment 3.0mm is used. Avoid the too high effect of tooth correction annex 2 to wear the comfort level, also avoid the annex height too low effect that can not play the support to influence the effect when correcting the tooth and turn over the jaw, it is to be noted that, the height of annex body 21 can be according to correcting the tooth and turn over the height that the back teeth promoted when the jaw carries out earlier stage design adjustment, in order to satisfy the actual demand of correcting positive and negative jaw.

As shown in fig. 1, the present embodiment further provides an orthodontic system, which includes an orthodontic device 3, and the orthodontic device 3 includes an orthodontic attachment 2, wherein the orthodontic device 3 includes a receiving cavity 31, and the second abutment surface 21b of the orthodontic attachment 2 abuts against the inner bottom of the receiving cavity 31, and the height of the attachment body 21 is greater than the depth of the receiving cavity 31. So that the accessory body 21 can be jacked up to the accommodating cavity 31 to form a protruding part during the process of wearing the dental appliance 3, and the upper jaw and the lower jaw can be supported; the marking function can be realized, and when other filling materials are used for replacement, the operation can be more accurate, thereby providing convenience for doctor operation; the inner wall of the accommodating cavity 31 is matched with the peripheral surface of the accessory body 21, so that the accessory body 21 is attached to the peripheral wall of the accommodating cavity, and looseness and abrasion are avoided. Further, the orthodontic accessory 2 is detachably disposed in the accommodating cavity 31, so that a variety of situations can be used, in this embodiment, a paste form is adopted, and whether to use a resin material for replacement can be selected according to the situation of the tooth 1.

The following describes the procedure and principle of use of the present embodiment:

the first abutting surface 21a of the accessory body 21 is stuck to the teeth 1 of the molar region according to the lifting height of the rear teeth when the inverse jaw of the teeth is corrected, the accessory body is normally stuck to the teeth 6 or the teeth 7 of the molar region of the lower jaw according to the situation, so that the fact that the orthodontic accessory 2 protrudes out of the teeth to affect the beauty of the mouth is avoided, the orthodontic device 3 is sleeved on the teeth 1, the orthodontic accessory 2 is placed in the accommodating cavity 31 of the orthodontic device 3, after the occlusion of the rear teeth of a patient is lifted, the occlusion of the front teeth is opened, at the moment, occlusion wounds in the process can be avoided when the inverse jaw of the teeth is corrected, as the height of the orthodontic accessory 2 is higher than the depth of the accommodating cavity 31, the orthodontic accessory 2 can be raised, a doctor can select whether to fill resin to replace the orthodontic accessory 2 according to the situation at the clinical end, if the resin is filled, the orthodontic accessory 2 is removed from the teeth 1, the resin is filled in the raised position of the orthodontic accessory 3 to be stuck to the teeth 1, and the operation difficulty of a doctor is greatly reduced.

It is to be understood that the above examples of the present utility model are provided for clarity of illustration only and are not limiting of the embodiments of the present utility model.
