Abstract

It is a kind of to rescue the invisible orthotic device without bracket dashed forward before jawbone, including appliance ontology, the draw hook being connected on appliance ontology, elastomer, anchorage part, it is characterized in that draw hook includes the pillar being connected on appliance ontology, triangular plate on pillar is set, elastomer includes spring, it is connected to triangle set of the spring wherein on one end, the shape of the triangle sets of holes of triangle set is identical as the shape of triangular plate, the triangle set boring ratio triangular plate of triangle set is big, when being in traction therapeutic state, the triangle sets of holes of triangle set are arranged in a staggered manner with triangular plate.Compared with the prior art the present invention, will not be changed with elastic force in use process, operate easy, elastic force is easily mastered, elastomer and be not easy impaired, elastomer and be not easy the advantages of falling off from draw hook.

Description

It is a kind of to rescue the invisible orthotic device without bracket dashed forward before jawbone

Technical field:

The present invention relates to a kind of medical instruments.

Background technique:

The clinical manifestation of bimaxillary protrusion malocclusion is X-ray cephalometry, and the upper long shaft declivity of mandibular teeth is big, and muffle is laborious And it is unnatural, 1/3 protrudes forward in face, and chin portion is smaller, seriously affects patient face type, it was reported that population of China bone bimaxillary protrusion Disease incidence be apparently higher than white people and Japanese.And orthodontic treatment is passed through for the patient to dash forward based on anterior protrusion of arch before jawbone Promising result can be obtained, the therapeutic purposes of bimaxillary protrusion are exactly the upper mandibular anterior teeth of receipts and alveolar process in maximum, thus Change malignant fibrous histocytoma indirectly.Therefore, Enhanced anchorase is needed to limit in the whole remote middle moving process of retract anterior teeth or upper mandibular The Forward ground one's teeth in sleep even promotes to grind one's teeth in sleep to move back, and there are two crucial: 1. anchorage points are obtained by cheekbone alveolar ridge Implant, 2. point of force application is obtained by the design of attachment on invisible orthotic device, persistently generates reinforcing by elastomer therebetween.As specially Disclosed in benefit 201520688306.0, using draw hook, elastomer uses the attachment on prior art invisible orthotic device Rubber band, due to that can generate creep in rubber band use process, elastic force can tentatively become smaller, so that the effect of traction is influenced, moreover, Rubber band is easy the fracture that is worn, using draw hook, rubber band has to cross gib head, and one is not easy that rubber band is made to be hooked in hook On head, two due to elastic force when crossing gib head and hang over the elastic force on hook and are different, thus it is not easy to elastic force is grasped, the Three, due to only constraining rubber band in one direction, rubber band is easy to fall off from gib head.

Summary of the invention:

Goal of the invention of the invention is to provide what elastic force in a kind of use process will not change, operation readily, bullet Power size is easily mastered, elastomer is not easy one kind that impaired, elastomer is not easy to fall off from draw hook and rescues jawbone Preceding prominent invisible orthotic device without bracket.

The invention is realized in this way including appliance ontology, the draw hook being connected on appliance ontology, elastomer, Anchorage part, its special feature is that draw hook includes the pillar being connected on appliance ontology, the triangle that is arranged on pillar Plate, elastomer include spring, are connected to triangle set of the spring wherein on one end, the shape of the triangle sets of holes of triangle set with The shape of triangular plate is identical, and the triangle set boring ratio triangular plate of triangle set is big, when being in traction therapeutic state, three Triangle sets of holes and the triangular plate of angular set are arranged in a staggered manner.

In use, appliance ontology is fixed on front teeth, anchorage part is implanted on the alveolar bone of cheek side, and the spring other end connects It connects on anchorage part, the triangle set of spring wherein one end covers on the pillar of draw hook, when socket, can cover triangle and swing Certain angle, the sets of holes for covering triangle are corresponding with triangular plate, and after socket, under the action of the spring, triangle set be can rotate It resets, the sets of holes for covering triangle are staggered with triangular plate, in this way, triangle is covered in the case where the four sides of triangular plate restricts, just not It can fall off from draw hook.

Compared with the prior art the present invention, will not be changed with elastic force in use process, operation is easy, elastic force is big Small be easily mastered, elastomer is not easy impaired, elastomer and is not easy the advantages of falling off from draw hook.

Detailed description of the invention:

Fig. 1 is the structural diagram of the present invention；

Fig. 2 is the rearview of Fig. 1 draw hook.

Specific embodiment: now in conjunction with drawings and examples, the invention will be described in further detail:

As shown in Figure 1, 2, the present invention includes the appliance ontology a being arranged on upper row's tooth e, is connected to appliance ontology Draw hook b, elastomer c, anchorage part d(on a use nail), draw hook b, elastomer c and anchorage part d have two sets, set respectively It sets on the both sides (only seeing the side therein appliance ontology a on figure) of appliance ontology a, its special feature is that draw hook b Including the pillar 1(that is connected on appliance ontology a using hollow cylinder, to mitigate weight), the triangle that is arranged on pillar 1 Plate 2, pillar 1 are located at the middle part of triangular plate 2 and by 2 complete hidings of triangular plate, and elastic c body includes spring 3, is connected to spring 3 The wherein triangle set 4 on one end, the shape of the triangle sets of holes 4a of triangle set 4 is identical as the shape of triangular plate 2, triangle The triangle sets of holes 4a of shape set 4 is bigger than triangular plate 2, as shown in Figure 1, when being in traction therapeutic state, triangle set 4 Triangle sets of holes 4a is arranged in a staggered manner with triangular plate 2.

Here, triangular plate 2 is equilateral triangle plate, and the triangle sets of holes 4a of corresponding triangle set 4 is equilateral triangle Shape sets of holes, the side length of equilateral triangle plate 2 are 1.2mm, and the triangle sets of holes 4a side length of triangle set 4 is 1.4mm.

Appliance ontology a, draw hook b are integral structure.
