Description

[0001] The present invention relates to a support member for orthodontic appliances,

The present invention relates to a support member for orthodontic treatment used for correcting a defective tooth. More specifically, a leg portion for fixing and fixing a screw is formed in a body portion formed in a straight bar shape, The front fixture of the leg portion is implemented on the left front side with respect to the center line dividing the center of the body portion and the rear fixture is on the rear right side with respect to the center line so that the upper teeth in the upper jaw are not directly corrected , Since a separate tool for correcting the upper teeth is not installed in the bore by correcting the upper jaw itself, the cost of the treatment is reduced and the operation is not necessary. Further, since the leg portion is bent forward, To further improve its functionality, and the screw Relates to a fixture and a room is only minimal damage to the implant by being hard palate rear fastener, palatine bone and the supporting member is not to secure the suture for teeth with minimal damage to the hard palate which do not inhibit or impair the growth of the growth plate of the maxilla correction.

In general, the maxillary and mandibular molars are the most lost teeth in dental treatment. When the opposing teeth are lost, the teeth are removed and the dental treatment becomes difficult. In particular, for the correction of the molar, , And the molar is calibrated using this fixed circle. In this case, orthodontic mini implants are mainly used as an anchor in the oral cavity.

Conventionally used mini-implants are embedded on both sides of the alveolar bone, and the elastic body is connected to the molars and mini-implants to apply an external force to the molar. In general, mini-implants must be placed in the alveolar bone below the teeth in order to securely fix the teeth, thus damaging the root of the tooth during the procedure, and also difficulty in precisely positioning the mini-implant.

Therefore, in order to fix the mini-implant to the inside of the oral cavity, the mucous membrane should be incised, and the mucous membrane should be incised to remove the fixed mini-implant.

In order to solve these problems, the present applicant has proposed Korean Patent No. 10-1083280 (support member for orthodontic correction), and the above-described technique is applied to the end portions at both sides as shown in Figs. 1, 2 and 3 A main body 11 having a plurality of hook portions 11a and a plurality of hook portions 11a extending radially from the central portion of the main body 11 and each having a through hole formed at a longitudinal end thereof, And at least three leg portions (12) fixed to the mucous membrane, wherein each of the leg portions (12) is configured to extend obliquely at a predetermined angle.

The above-mentioned "supporting member for orthodontic treatment " has an effect of correcting the teeth by pulling the upper jaw itself together with the upper jaw in the upper jaw so as to correct not only the upper teeth but also the upper teeth in the upper jaw, Since the leg portion is located at the rear side compared with the optimal range of the screw placement, there is a limit in placing due to the amount of bone, the bone quality and the soft tissue thickness, and there is a problem that space for securing the elastic body to the hook portion and securing visibility are not easy.

The present applicant proposed Korean Patent No. 10-1314315 (a leg support member for orthodontic braces bent backward in parallel) in order to solve such a further problem, A plurality of leg portions 30 formed in a central portion of the main body 10 and radially formed in the central portion of the main body 10 and formed with through holes 31 for placing screws, And the hook portion 20 is formed to be parallel to the main body 10 while the leg portion 30 is folded back 3 to 8 mm from the main body in front of the human body and forward in the present application, 10, and a retaining jaw 22 formed at an end of the fastening hole 21. The fastening hole 22 is formed in the fastening hole 21,

The above-mentioned " orthodontic support member whose leg portions are folded back in parallel "extends the action range of the force to the front of the teeth constantly, secures a space for attaching the elastic body to the hook portion, And the elastic body is not easily detached by the latching jaw.

However, in the prior art, the legs are radially formed at the center of the body, so that at least three through-holes are formed to form a triangle in order to securely fix the orthodontic support member, And the pelvis. In particular, when the screw is inserted into the maxillary suture line or the pelvic suture line passing through the center of the pelvis, it may cause fatal damage to the pelvis. In the case of children under 15 years of age, There is a problem in that the suture line may not have been completely sealed and thus may have a deformed oral structure.

In the prior art, since at least three leg portions are formed, at least two leg portions are provided on either the front side or the rear side. If the growth plate is not yet closed and the growth plate is not closed, The maxilla is fixed and obstructs the growth of the maxilla due to the growth plate, resulting in a deformed problem that is larger than the maxilla of the mandible, or the balance of the maxilla and the palatine collapses, or the maxillary and pelvic suture lines become normal There is a problem in that it is not sealed with the sealing member.
