Periodontal fixator

Abstract

The utility model discloses a periodontal fixator which comprises a left belt ring matched with left molar teeth, a right belt ring matched with right molar teeth and an arc-shaped strip matched with anterior teeth, and the two ends of the arc-shaped strip are connected with the left belt ring and the right belt ring respectively. The periodontal fixator further comprises planting nail connecting pieces connected to the left belt ring, the right belt ring and the arc-shaped strip. The periodontal fixator further comprises rubber band connecting pieces connected to the left band ring, the right band ring and the arc-shaped strip. Before the orthognathic operation is finished, the periodontal fixator is respectively fixed on an upper jaw bone and a lower jaw bone through the planting nails, and the upper tooth periodontal fixator is connected with the lower tooth periodontal fixator through the rubber band, so that the occlusion relationship between the upper row of teeth and the lower row of teeth can be fixed after the orthognathic operation; the periodontal fixator can also be used for indirectly fixing periodontal mucosa after an operation is completed.

Description

Technical Field

[0001] The utility model relates to a medical device, in particular to a periodontal fixator. Background Art

[0002] Dento-maxillofacial deformity refers to the abnormal volume and shape of the jawbones, as well as the abnormal relationship between the upper and lower jawbones and other craniofacial bones. It also includes abnormal jaw and tooth relationships, abnormal functions of the stomatognathic system, and abnormal facial morphology. In the prior art, dento-maxillofacial deformity is usually corrected by orthognathic surgery. Before orthognathic surgery, orthodontic treatment is required to align the teeth, and then orthognathic surgery is performed. After orthognathic surgery, the occlusal relationship between the upper and lower teeth needs to be fixed. If orthodontic brackets are pasted on the teeth during the previous orthodontic treatment, rubber bands can be directly connected to the orthodontic brackets after orthognathic surgery to fix the occlusal relationship between the upper and lower teeth. If invisible aligners are used during the previous orthodontic treatment, there is no structure on the teeth after orthognathic surgery to fix the occlusal relationship between the upper and lower teeth. Therefore, a device capable of fixing the occlusal relationship between the upper and lower teeth after orthognathic surgery needs to be designed. Content of the Utility Model

[0003] In view of this, the purpose of the utility model is to provide a periodontal fixator to solve the technical problem of fixing the occlusal relationship between the upper and lower teeth after orthognathic surgery.

[0004] The periodontal fixator of the utility model includes a left band loop matched with the left molar, a right band loop matched with the right molar, and an arc bar matched with the anterior teeth. The two ends of the arc bar are respectively connected with the left band loop and the right band loop;

[0005] The periodontal fixator further includes a planting nail connecting piece connected to the left band loop, the right band loop, and the arc bar;

[0006] The periodontal fixator further includes a rubber band connecting piece connected to the left band loop, the right band loop, and the arc bar.

[0007] Further, the planting nail connecting piece includes a connecting rod connected to the left band loop, the right band loop, or the arc bar, and a collar located at the end of the connecting rod.

[0008] Further, the rubber band connecting piece includes a column convex connected to the left band loop, the right band loop, or the arc bar, and a ball head connected to the end of the column convex.

[0009] Further, the rubber band connecting pieces correspond to the teeth one by one.

[0010] Advantages of the Utility Model

[0011] Before the orthognathic surgery ends, fix the periodontal fixator of the present utility model on the maxilla and mandible respectively through implanting pins, and connect the upper tooth periodontal fixator and the lower tooth periodontal fixator with rubber bands. In this way, the occlusal relationship between the upper teeth and the lower teeth can be fixed after the orthognathic surgery, and the periodontal mucosa after the surgery can also be indirectly fixed by this periodontal fixator. Brief Description of the Drawings

[0012] Figure 1 It is a schematic diagram of the periodontal fixator arranged on the periodontium of the upper teeth and the lower teeth.

[0013] Figure 2 It is a top view schematic diagram of the periodontal fixator arranged on the periodontium of the upper teeth. Detailed Description of the Preferred Embodiment

[0014] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0015] As shown in the figure, the periodontal fixator of this embodiment includes a left band 1 cooperating with the left molar, a right band 2 cooperating with the right molar, and an arc bar 3 cooperating with the anterior teeth. Both ends of the arc bar are respectively connected with the left band and the right band.

[0016] The periodontal fixator further includes an implanting pin connector 4 connected to the left band, the right band, and the arc bar. The implanting pin connector includes a connecting rod 41 connected to the left band, the right band, or the arc bar, and a collar 42 located at the end of the connecting rod. In specific implementation, the number and position of the implanting pin connectors 4 can be reasonably set according to actual needs.

[0017] The periodontal fixator further includes a rubber band connector 5 connected to the left band, the right band, and the arc bar. The rubber band connector includes a columnar protrusion 51 connected to the left band, the right band, or the arc bar, and a spherical head 52 connected to the end of the columnar protrusion. In this embodiment, the rubber band connectors correspond to the teeth one by one.

[0018] Before the orthognathic surgery ends, fix the periodontal fixator of this embodiment on the maxilla and mandible respectively through implanting pins, and connect the upper tooth periodontal fixator and the lower tooth periodontal fixator with rubber bands. In this way, the occlusal relationship between the upper teeth and the lower teeth can be fixed after the orthognathic surgery, and the periodontal mucosa after the surgery can also be indirectly fixed by this periodontal fixator.

[0019] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present utility model and not to limit them. Although the present utility model has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present utility model can be modified or equivalently replaced without departing from the purpose and scope of the technical solutions of the present utility model, and they should all be covered within the scope of the claims of the present utility model.
