Abstract

It is a kind of to rescue the invisible orthotic device without bracket dashed forward before jawbone, including appliance body, it is connected to the draw hook on appliance body, elastomer, anchorage part, it is characterized in that draw hook includes the pillar being connected on appliance body, it is arranged on the triangular plate on pillar, elastomer includes spring, it is connected to the triangle set on spring wherein one end, the shape in the triangle set hole of triangle set is identical with the shape of triangular plate, the triangle set boring ratio triangular plate of triangle set is big, when in traction therapeutic state, triangle set hole and the triangular plate of triangle set stagger setting.Compared with the prior art the utility model, will not change with elastic force during use, operation readily, elastic force be easily mastered, elastomer be not easy the advantage that impaired, elastomer is not easy to be come 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 utility model is related to a kind of medicine equipment.

Background technology：

The clinical manifestation of bimaxillary protrusion malocclusion is X-ray cephalometry, and upper mandibular teeth shaft declivity long is big, and muffle is laborious And it is unnatural, 1/3 protrudes forward in face, and chin portion is smaller, has a strong impact on patient face type, it was reported that population of China bone bimaxillary protrusion The incidence of disease apparently higher than white people and Japanese.And the patient for being dashed forward based on anterior protrusion of arch before jawbone passes through orthodontic treatment Can obtain promising result, the therapeutic purposes of bimaxillary protrusion are exactly mandibular anterior teeth and alveolar process in interior receipts to greatest extent, so that Change malignant fibrous histocytoma indirectly.Therefore, Enhanced anchorase is needed to limit in the overall remote middle moving process of retract anterior teeth or upper mandibular The reach ground one's teeth in sleep even promotes to grind dental retrusion, there is two keys：1. anchorage point, is obtained by cheekbone alveolar ridge Implant, 2. point of force application, is obtained by the design of annex on invisible orthotic device, persistently produces reinforcing by elastomer therebetween.As specially Disclosed in profit 201520688306.0, the annex on prior art invisible orthotic device uses draw hook, and elastomer is used Rubber band, due to that can produce creep during rubber band use, elastic force can tentatively diminish, so that the effect of traction is influenceed, and, Rubber band is easily worn fracture, using draw hook, rubber band has to cross gib head, and one is not easy to make rubber band be hooked in hook On head, two being different due to crossing elastic force during gib head and hanging over the elastic force on hook, thus it is not easy to elastic force is grasped, the Three, due to only constraining rubber band in one direction, therefore, rubber band easily comes off from gib head.

Utility model content：

Goal of the invention of the present utility model is that elastic force will not be changed during providing a kind of use, and operation is easy , elastic force is easily mastered, elastomer is not easy one kind that impaired, elastomer is not easy to be come off from draw hook and rescues The invisible orthotic device without bracket dashed forward before jawbone.

The utility model is achieved in that including appliance body, the draw hook being connected on appliance body, elasticity Body, anchorage part, it is particular in that draw hook includes the pillar being connected on appliance body, the triangle being arranged on pillar Shape plate, elastomer includes spring, the triangle set being connected on spring wherein one end, and the triangle of triangle set covers the shape in hole Shape with triangular plate is identical, and the triangle set boring ratio triangular plate of triangle set is big, when in traction therapeutic state, Triangle set hole and the triangular plate of triangle set stagger setting.

When using, appliance body is fixed on front teeth, and on the alveolar bone of anchorage part implantation cheek side, the spring other end connects It is connected on anchorage part, the triangle set of spring wherein one end is enclosed within the pillar of draw hook, during socket, triangle can be covered and swung Certain angle, the set hole for covering triangle is corresponding with triangular plate, and after socket, under the action of the spring, triangle set can be rotated Reset, the set hole for covering triangle is staggered with triangular plate, so, triangle is enclosed within the restriction of the four sides of triangular plate, just not Can be come off from draw hook.

Compared with the prior art the utility model, will not change with elastic force during use, and operation is easy, bullet Power size is easily mastered, elastomer is not easy the advantage that impaired, elastomer is not easy to be come off from draw hook.

Brief description of the drawings：

Fig. 1 is structural representation of the present utility model；

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

Specific embodiment：The utility model is described in further detail in conjunction with drawings and Examples：

As shown in Figure 1, 2, the utility model includes appliance body a on the row of being arranged on tooth e, is connected to appliance Draw hook b, elastomer c, anchorage part d on body a（Using nail）, draw hook b, elastomer c and anchorage part d have two sets, divide The both sides of appliance body a are not arranged on（Appliance body a sides therein are only seen on figure）, it is particular in that traction Hook b includes the pillar 1 being connected on appliance body a（Using hollow cylinder, to mitigate weight）, be arranged on pillar 1 three Angular plate 2, pillar 1 is located at the middle part of triangular plate 2 and by the complete hiding of triangular plate 2, and elastic c bodies include spring 3, are connected to bullet Triangle set 4 on the wherein one end of spring 3, the shape of the triangle set hole 4a of triangle set 4 is identical with the shape of triangular plate 2, The triangle set hole 4a of triangle set 4 is bigger than triangular plate 2, as shown in figure 1, when in traction therapeutic state, triangle Triangle set hole 4a and the triangular plate 2 of set 4 stagger setting.

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