Description

Orthodontic draw hook

Technical Field

The utility model belongs to the technical field of the orthodontic tool, concretely relates to just abnormal hook that pulls of root tooth.

Background

Abnormal growth of teeth, abnormal growth of jaw bones, bad habits such as finger sucking during an infant, poor eating habits, and/or heredity may cause the teeth and the oro-jaw not to grow in place, thereby causing irregularly arranged teeth, malocclusion (a state in which the occlusions of the teeth do not match), or facial prominence. Irregular arrangement of teeth, malocclusion, or facial protrusion may cause inactivity in interpersonal relationships and also reduce uniform chewing of food as a basic function of teeth. Therefore, in order to solve these problems, it is increasingly common in orthodontic treatment to move teeth by applying a constant force to the teeth so as to reorganize alveolar bones surrounding the teeth. Orthodontics, also called orthodontics, is the correction of deformities of teeth. Orthodontics is primarily orthodontic tooth correction.

In the conventional orthodontic procedure, one end of the traction unit is connected to an anchor implanted in a jawbone or an alveolar bone, and the other end thereof is connected to a lower protrusion of the bracket at an angle (an angle of θ 1 with respect to a horizontal direction of the anchor). In this case, since the connection angle of the traction unit connected to the bracket is inclined with respect to the anchor, a tensile force F1 is exerted on the tooth T during the orthodontic process. For this reason, the tooth T and the tooth root T' are not horizontally pulled, and the tooth T is pulled in the oblique direction inclined at the angle θ 2. Therefore, a skew phenomenon occurs. In the conventional orthodontic device, when orthodontic treatment is performed by connecting the traction unit to the bracket-type orthodontic device, teeth are obliquely pulled. Therefore, it is difficult to perform normal orthodontic treatment, and the orthodontic period is long.

SUMMERY OF THE UTILITY MODEL

The utility model aims at providing an orthodontic traction hook solves in traditional orthodontic device, when carrying out orthodontic treatment through linking to each other traction element and bracket type orthodontic device, tooth is pulled by skew ground, consequently, is difficult to carry out normal orthodontic treatment, and the longer problem of orthodontic cycle.

In order to achieve the above purpose, the utility model adopts the following technical scheme:

the utility model provides a tooth orthodontic draw hook, which comprises a tooth attachment unit, wherein the tooth attachment unit is used for being attached to an orthodontic tooth object; a hook member is fixedly connected to the tooth attachment unit, the hook member being used to connect to a traction unit, the hook member extending to at least the vicinity of a gum; the hook piece is provided with a plurality of, the hook piece is S-shaped, and a plurality of the hook piece connects gradually.

According to the technology, the hook piece is arranged to extend to at least the vicinity of the gingiva, after the hook piece is connected with the traction unit, generally, the traction unit is generally positioned on the other traction hook on other teeth, and the hook pieces of the two traction hooks are sleeved with the rubber band, so that the pulling force of the rubber band is exerted from the vicinity of the gingiva, the direct traction and the force application from the dental crown can not be carried out, and the problem that the teeth are obliquely pulled can be effectively avoided; in addition, through the arrangement of the plurality of end-to-end S-shaped hook members, in actual use, because the distances from teeth to gingiva of different patients are different, the required length of the hook members is different, therefore, redundant hooks can be eliminated according to the actual requirements of orthodontists, the traction hook is prevented from being manufactured on site, and the working efficiency is improved; the problem of using a uniform draw hook that does not meet the needs of all orthodontics is also avoided.

In one possible design, the tooth attachment elements are mesh sheets. The tooth attachment unit is arranged as the grid sheet, so that the bonding is firmer and not easy to fall off, the sheet design can be more attached to teeth, and the foreign body sensation in the oral cavity is reduced.

In one possible design, at least 3 hooks are provided. By providing at least 3S-shaped hooks, the range of applicability is greater since the S-shaped hooks have two hooks, and thus there are at least 6 hooks.

In one possible design, the hook member is a stainless steel wire with a circular cross section, and the diameter of the stainless steel wire with a circular cross section is 0.9mm to 1 mm.

In one possible design, the distance between the hook center points of every two adjacent hook elements is 1.8mm to 2.1 mm.

In one possible design, the tooth attachment unit is connected between the fixing part and the hook part through a connecting rod, an arc-shaped protrusion is arranged at one end of the connecting rod close to the tooth attachment unit, and the arc-shaped protrusion is arranged opposite to one side, which is attached to the tooth, of the tooth attachment unit. Through setting up the arc arch for the gum can be by-passed by to the hook piece, avoids oppressing the gum.

In one possible design, the arc-shaped protrusion forms a distance of 0.67mm to 0.73mm from the plane in which the tooth attachment unit is located.

In one possible design, an end of the connecting rod adjacent to the tooth attachment unit is spaced from an end of the connecting rod adjacent to the hook by 2.5mm to 3.5 mm.

In one possible design, the hook member is made of a stainless steel wire having an oval cross-section. The hook piece is arranged, so that the cross section of the hook piece is made of the oval stainless steel wire, and the foreign body sensation can be reduced.

In one possible design, the long axis of the hook is 0.9mm to 1m long and the short axis of the hook is 0.2mm to 0.3mm long.
