Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an oral fixation device and an oral anchoring device,

More particularly, the present invention relates to an oral fixation screw and a fixation plate capable of fixing a device requiring tooth movement in a treatment requiring oral tooth movement including a correction and an implant, And a mouth plate.

Generally, a fixed circle is required when an anterior projection or the like is to be moved backward or when teeth are to be moved in a specific direction. In other words, one part should not move as a fixed circle, and the teeth to be moved must be given sustained force.

In recent years, fixation sources are used in various forms for fixation in a palatal bone so as to be able to provide a firm bone quality while sufficiently avoiding damaging tissues such as teeth and nerves.

For example, as shown in FIG. 1A, a palate (palate) is formed in a central portion of a metal core having a predetermined length and elasticity bending in an arch shape, A predetermined fixing plate having a fixing part formed thereon is installed using a screw and a steel wire is connected to a plate attached to a tooth to be moved and then a tension can be applied by connecting the steel wire to a fixing plate with a spring, The configuration is known.

Further, the orthodontic fixture for orthodontic treatment shown in Fig. 1B has a plate-shaped base portion having four peripheries, a spherical surface and a spherical inner surface; A pair of fixing pieces each extending from two mutually opposed peripheral portions of the base portion, each of the pair of fixing pieces being formed so as to be stepped with respect to the base portion toward the spherical surface side; And a pair of annular protrusions each extending from two opposite sides of the base portion and each formed to be inclined toward the inner side of the sphere.

As described above, since the conventional palatal fixation device has a structure in which two or more screws for fixing the fixation plate are installed to prevent rotation of the fixation plate, it not only increases the patient's pain but also can not be replaced with a new fixture plate once fixed It was a very difficult structure to exchange.

In addition, the fixation circle is incompatible with other orthodontic appliances when it functions as a fixation source, and therefore, the fixation circle must be inserted in the oral cavity for a long period of time in case the fixation circle is needed again.

In addition, the fixed circle has a problem that the contact area with the mucous membrane directly or indirectly from the portion buried in the mucous membrane of the palatal mucosa and the external causes damage or inflammation to the mucous membrane of the palatal mucosa.

Therefore, there has been a need to develop an oral fixation device in which such problems have been solved.
