Description

Apparatus for driving a anchor of straightening teeth}

The present invention relates to an anchor insertion device for orthodontic treatment, comprising: connecting a plurality of teeth integrally and anchoring for orthodontic implantation of a mini screw anchor for supporting a tooth calibration wire for correcting the warping state of each tooth Relates to a device.

Normally during orthodontic treatment to treat malocclusion, moving teeth (usually "forearms") and immobilized teeth (mostly "molars") should not move for better chewing in the molar area and for better pronunciation and aesthetics in the forearm area. It is very important to control the proper force between the two.

For example, when correcting a coarse or crooked tooth, use a orthodontic device consisting of a bracket attached to the tooth and a orthodontic wire that connects it between teeth when removing the small molars and causing the incisor to move into this space. Done.

Due to this orthodontic device is applied to the front teeth moving toward the molars. However, the opposite reaction appears in the molar area, so that the molars that should not be moved are moved forward to occupy the space of the extracted tooth area, thereby preventing the incisor from moving as much as desired.

Thus, so-called orthodontics use oral orthodontic devices (headgears) that are detachable to teeth for anchor reinforcement purposes in order to reduce this reaction and to provide space for the mobile teeth to move sufficiently. However, in the case of adults, it is difficult to obtain a surgical coordination of a removable orthodontic appliance (headgear) because of aesthetic reasons and the hassle of inserting and removing.

Thus, in recent years, a small screw called a mini implant (hereinafter referred to as a "mini screw anchor") is placed in the gum between the roots of the teeth and the teeth to be corrected by the mini screw anchors are ligated using an orthodontic elastic material. By doing so, it is used as a firm and continuous fixed source. These mini screw anchors are invisible because they are placed between the roots of the teeth, and because of their high fixed strength, they can exert their strength all day long, so that the movement of the teeth to be corrected appears quickly.

However, even if the location of the miniscrew anchor is determined, the gums are covered and the molar area is obliquely secured. Therefore, precisely placing the miniscrew anchors to the insertion position using a tool such as a screwdriver depends on the experience of the operator. none.

Therefore, in the past, the process of placing the mini screw anchor is not easy, and the direction of the mini screw anchor passing through the gum may be offset from the bone center between the roots of the teeth. There is a drawback that time and cost must be increased.

Accordingly, an object of the present invention is to provide an orthodontic anchoring device for easily mini-anchor anchoring to a predetermined position.

In addition, another object of the present invention is to provide an orthodontic anchoring device for shortening the implantation procedure time of the mini screw anchor and to reduce its cost.
