Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an orthodontic device used for the treatment of dental malocclusion, and particularly relates to an orthodontic device that is used for treating malocclusion of teeth.
The left and right sides and angles can be adjusted and moved, and after adjustment and movement, the surgeon (
Stop the archwire in the position desired by the orthodontist,
This relates to the structure of a placket that can be fixed.

In dentistry whose main purpose is to treat dental malocclusion, the latest and most advanced method is to attach archwire fixing brackets (1) to each tooth (2 tons), as shown in Figure 1.
) (z2)..., and this bracket (1)...
This is a method in which one orthodontic archwire (3) is sequentially fitted and fixed in the archwire (3), and the teeth (2,) are corrected by the elasticity of the archwire (3). For example, as shown in Fig. 1, when the central incisors (21) of the upper jaw are abnormally protruding outward as shown by the solid line, and the molars (21) are to be corrected in the vertical direction as shown by the chain lines, or If it is necessary to prevent anchorage losses,
The archwire (3) must be given a large curvature in the vertical direction. To attach such a pre-curved Doug archwire 3) into the oral cavity, first fix both ends of this archwire (3) to the brackets (1) of the molars or premolars (20). When both ends of the archwire (3), which was pale and pale in the vertical direction, were fixed at the tips, the central part (4) of the archwire (3) would dig into and come into contact with the gums and lips. As a result, patients complained of pain, and it was extremely difficult for surgeons to operate this archwire (3).

The biggest reason for this is that the bracket (1) of the molar part (221) that fixes the tip of the archwire (3) fixes the archwire (3) from the beginning. In such a case, if the bracket (1) of the molar part (22) that fixes the tip of the archwire (3) is movable, just insert the archwire (3) at first, and then adjust it to the specified angle later. Archwire (3)
The central part (4) of the patient does not touch the patient strongly, making it easier for the operator to operate and shortening the treatment time.

If such a method is adopted, instead of the conventional method of fixing brackets to the outside of the teeth shown in the upper jaw in Figure 1, it is possible to fix the brackets to the inside of the teeth shown in the lower jaw in Figure 1. It is particularly effective when used in the lingual buffet method (recently developed by the applicant and hereinafter referred to as the Fujita method), which treats the lingual side.

In addition, in orthodontic treatment, the position of archwire holding devices such as brackets, wire insertion tubes, etc. that are attached to tooth surfaces with bands or directly bonded with adhesive plates is extremely important. If this position is even slightly inconvenient, conventional methods include reattachment, reattachment, or forcibly bending the archwire, but these operations are cumbersome and cause great pain and strain on the patient. I was playing. Therefore, if the position of the bracket tube could be adjusted to some extent even after installation, it would be of great benefit to the patient and the surgeon.

The present invention has been made in view of the above points, and includes an archwire holding device that is rotatably and/or movably provided on a substrate that is fixed to the teeth, and that is fixed integrally with a fixing portion after adjustment. It is.

Examples of the present invention will be described below.

In Figure 2, the fixed board (5) has teeth (2,) (2□)...
The case is shown in which a tube body (6) as an archwire holding device rotates around a rotating shaft (7) as a retaining means on the outer surface of this fixed base plate (5). It is attached movably and can be fixed in a predetermined position by a fixing part (8) such as a screw as a fixing means. Further, this tube body (6) is integrally provided with an insertion tube (9) into which the archwire (3) is inserted.

FIG. 3 and subsequent figures show the case where the fixed substrate (5) is an adhesive plate having a size of about 4 to 5 parts per side. In the following, the case of using an adhesive plate will be described as an example, but it goes without saying that a band may be used in any case. In FIG. 3(a), the fixed substrate (
5) is bonded to the outer or inner surface of the tooth with an adhesive, and therefore, as described later, it is desirable that it be slightly curved to match the surface shape of the tooth. Its shape will be described later. On the - side of this fixed board (5), one side is 3
A tube body (6) of approximately 4 mm is provided rotatably by a rotating shaft (7). This tube body (6) is
Gold JF71 Made of synthetic resin, composite material, alumina, etc. Further, this tube body (6) is provided with a fixing portion (8) such as a screw, and is also integrally provided with an insertion tube (9) into which the archwire (3) is inserted. In FIG. 3(a), a stopper (10) may be integrally provided on the fixed base plate (5) to prevent the tube body (6) from rotating any further in a certain direction. When it is rotated in the direction, a scale (111 may be attached) to indicate the angle of rotation.

It is inserted and fixed.

FIGS. 4(a) and 4(b) show an example in which the screw constituting the fixing part (8) advances and retreats in an inclined direction with respect to the tube body (6). In particular, when attaching to the molar region (20) or the inner surface of the tooth, this is to make it easier to insert the screwdriver into the oral cavity and turn it from the labial side. may be changed.

Furthermore, as shown in FIG. 4(C), the fixed substrate (5) and the tube body (6) may be partially bent so as to be approximately perpendicular to the direction of the screw (8).

FIG. 5 shows an example in which an arc-shaped elongated hole (18) is formed in the tube body (6) so that the screw serving as the fixing part (8) can be fixed at any position.

Fig. 6 shows an example in which the rotating shaft (7) and the fixed part (8) are integrated, and in this example, the shaft α9 is integrated with the fixed board (5).
An example is shown in which the cylindrical part @) of the tube body (6) is fitted, and a bar-shaped pin Q7+ biased by a spring (16) is inserted into the hole (21+ (221) penetrating each). ing.

Since the archwire is provided in the archwire and is configured to be fixed by such a fixing means, the archwire is bent in advance according to the predetermined orthodontic purpose, and then the tip of the archwire is temporarily fixed to the archwire holding device of the molar region. After that, the brackets and tubes are fitted to each tooth according to their position.Finally, the position of the archwire retaining device for the molar region is corrected and fixed to the fixed base using the fixed part, so that the central part of the archwire is It does not touch the patient's mouth so that it penetrates strongly into the patient's mouth, and it is also extremely easy for the operator to operate. Of course, traditional methods of attaching brackets or tubes to the outer surface of the tooth,
It is extremely effective when used in the so-called Fujita method, in which brackets or tubes are attached to the inner surface of the tooth. Furthermore, if a slight gap is created at the rotation axis, accurate correction can be made without the need for reinstalling brackets or tubes or forcibly bending the archwire.
