Description

Detailed Description of the Invention

[0001]

INDUSTRIAL APPLICABILITY The present invention is used in the field of oral surgery for the treatment of jawbone surgery, fractures and tooth dislocations, or for the retention of teeth after periodontal disease and orthodontic treatment. The present invention relates to improvement of an oral surgery bracket used.

[0002]

2. Description of the Related Art As a conventional bracket for oral surgery of this kind, there is one disclosed in Japanese Utility Model Publication No. 2-21052.
As shown in FIG. 6, the conventional bracket for oral surgery has a curved body shape in which the bracket body 1 is formed into a plate shape with a metal material such as stainless steel, and is adapted to the interdental shape of the teeth adjacent to the plate body 1. On the other hand, the U-shaped hook body 3 for locking the ligature wire is fixedly welded to the recess 2 defined in the central portion on the front surface side of the bracket body 1.

In actual use, as shown in FIG. 7, when an adhesive is applied to the back surface of the bracket body 1 and the bracket body 1 is adhered across the surfaces of adjacent upper and lower teeth T. Due to the above-described curved surface shape, the bracket body 1 can be fitted and adhered to the teeth T, and at the same time, the adjacent teeth T of the patient can be reliably fixed. After the interdental fixation of this patient is obtained, as shown in the drawing, the ligature wire W is alternately applied to each hook body 3 of the bracket main body 1 which is adhered across the adjacent upper and lower teeth T. This allows the upper and lower jaws of the patient to be fixed at the same time. Therefore, such a conventional bracket for oral surgery has an advantage that interdental fixation and intermaxillary fixation required for treatment of oral surgery can be performed at the same time.

[0004]

However, in the conventional oral surgery bracket, both the bracket body 1 and the U-shaped hook body 3 fixed to the body 1 are made of a metal material. , When a patient opens their lips, it appears to the third person as black lumps, so they tend to be shunned from an aesthetic point of view.

Further, in the treatment of oral surgery, the period of time required for fixation between the upper and lower jaws is usually at most 1 to 2 months, but the period of time required for fixation between the teeth is considerably longer than this. It has been a long period of time, and especially in the case of periodontal disease, there are cases in which it is necessary to continue to fix the interdental teeth for a long period of about one year. Therefore, if the conventional bracket for oral surgery is continuously mounted even during the period in which only the fixation between the teeth is required, the hook body 3 for locking the ligature wire W for the intermaxillary fixation becomes unnecessary. Despite this, since the hook body 3 is still fixed to the bracket body 1, the presence of the hook body 3 interferes with the bracket body 1 and gives the patient discomfort and discomfort for a long time. It had a big problem that Therefore, in view of the problems of the conventional bracket for oral surgery, the present invention provides a novel bracket for oral surgery that can be used exclusively for interdental fixation.

[0006]

In order to achieve the above object, the first aspect of the present invention is to provide a colorless and transparent bracket main body having a curved surface shape adapted to the interdental shape of the teeth adjacent to each other on the back side. A configuration was adopted in which the bracket was molded from a material and the surface side of the colorless and transparent bracket body was rounded. The second invention is that a bracket main body having a curved surface shape adapted to the interdental shape of the teeth adjacent to each other on the back surface side is formed of a semitransparent material, and the front surface side of the semitransparent bracket main body is formed. A rounded configuration is adopted. Furthermore, a third invention is that a bracket body having a curved surface shape adapted to the interdental shape of teeth adjacent to each other on the back surface side is molded with a metal material, and the front surface side of the bracket body made of the metal material is rounded. A structure in which the surface of the bracket body is made to be crowned and a crown-colored coating is applied is adopted.

[0007]

According to the present invention, therefore, in any of the inventions, a proper amount of adhesive is applied to the back surface of the bracket body, and the bracket body is gripped at the proper place while the bracket body is being held. If the back surface of the bracket is bonded across the surfaces of adjacent teeth, the curved body shape that is applied to the back surface allows the bracket body to fit and bond between the teeth, and at the same time, continue between the adjacent teeth of the patient. Then, it is possible to securely fix it.

In addition, in the mounted state of the bracket, it goes without saying that the bracket body is made of a colorless transparent or translucent material, but for example, the bracket body is made of a metal material. However, since the surface is coated with a crown color, in any case, unlike the conventional metal one, even if the patient's lips are opened, it will be darkened by a third party. It will not be visible to the eyes of the eyes and will greatly contribute to the improvement of aesthetics.
In addition, since the surface side of this bracket body is only rounded and does not have a hook body that protrudes considerably in the cheek direction as in the conventional case, even if it is worn for a long period of time, the patient does not feel uncomfortable. It also reduces the feeling of strangeness.

[0009]

EXAMPLES Hereinafter, the present invention will be described in detail with reference to the illustrated examples. The oral surgery brackets according to any of the examples are different from the conventional ones and are used exclusively for interdental fixation of a patient. Since it was developed as a product, it does not have any U-shaped hook body for locking the ligature wire.

First, the bracket for oral surgery according to the first embodiment will be explained. As shown in FIG.
1 is molded into an elliptical shape having a rounded front surface side, and a curved surface shape adapted to the interdental shape of adjacent teeth is provided on the rear surface side of the bracket body 11, and a central portion on the rear surface side having the curved surface shape is provided. On the other hand, the ridges 12 that enter the recesses between the teeth and serve as positioning references for bonding are integrally formed, while the bracket body 1
A small protrusion 13 that can be directly grasped by forceps or tweezers is integrally formed in the central portion on the front surface side of 1. In the first embodiment, when the bracket body 11 having the above-mentioned configuration is molded, it is integrally molded with a colorless and transparent material or a semitransparent material, or when it is molded with a metal material, The entire surface of the metal bracket body 11 is positively coated with a crown color to improve aesthetics.

The colorless and transparent material may be a plastic material such as acrylic or polycarbonate, a ceramic material, or a glass material, and the semitransparent material may be a plastic material containing a filler or an alumina polycrystal. Ceramic materials are considered, and as crown-colored coatings, plastic coatings, ceramic coatings, metal oxide / metal nitride coatings, etc., which have the same color and luster as natural teeth, are possible.
The present invention is not limited to these, and it is also optional to obtain a bracket main body 11 with high aesthetics by selecting other molding materials and coatings depending on the implementation.

Therefore, when the bracket for oral surgery of the first embodiment is used, this bracket is exclusively used for interdental fixation of a patient. First, a bracket capable of simultaneously performing interdental fixation and intermaxillary fixation, That is, using the above-mentioned bracket shown as a conventional example and other known brackets, after performing treatment that requires intermaxillary fixation, it is used to perform interdental fixation that requires long-term mounting. Will be done. When the bracket is exclusively used for fixing the interdental teeth, first, a state in which an appropriate amount of adhesive is applied to the back surface of the bracket main body 11 is obtained, and the small projection portion formed on the front surface side of the main body 11 is obtained. While gripping 13 with forceps, tweezers (not shown), or the like, align the ridges 12 formed on the back surface side of the main body 11 with the recesses between the corresponding teeth T, and set the back surface of the main body 11 to adjacent teeth. When it is adhered across the surfaces of T,
As shown in FIG. 2, due to the action of the curved surface provided on the back surface side, the bracket body 11 itself is conformed and adhered between the teeth T, and at the same time, the adjacent teeth T of the patient can be reliably fixed. It will be possible.

Moreover, in the mounted state of the bracket, as described above, it goes without saying that the bracket body 11 is made of a colorless transparent or translucent material.
For example, even if the bracket body 11 is formed of a metal material, the surface of the bracket body 11 is coated with a crown color equal to that of natural teeth, so in any case,
Unlike traditional metal ones, even if the patient opens their lips,
It will not be seen by a third party as blackened,
This will greatly contribute to improving aesthetics. Further, on the front surface side of the bracket main body 11, a small projection portion 1 serving as a grip portion is provided.
When 3 is formed, the small protrusion 13 does not project considerably in the cheek direction unlike the conventional hook body,
Since the protruding amount is small enough to be held by forceps or tweezers, the roundness on the surface side of the main body 11 may cause discomfort or discomfort to the patient even if the device is worn for a long period of time. Disappear.

Next, the bracket for oral surgery according to the second embodiment will be explained. This bracket is basically the same as described above, including molding by a colorless transparent or translucent material and a crown color coating. Although the configuration of the first embodiment is assumed as it is, the difference is that the first embodiment forms the small projection portion 13 serving as a grip portion so as to project to the surface side of the main body 11. In the second embodiment, as shown in FIG. 3, a pair of recesses 1 is provided in the central portion on the front surface side of the main body 11 so that it can be held by forceps or tweezers.
4 is formed and the pair of recesses 14 is used as a grip.

Therefore, even when the bracket for oral surgery according to the second embodiment is used, the protrusions 12 formed on the back side of the main body 11 are supported while gripping the pair of recesses 14 with forceps, tweezers or the like. By matching the recesses between the teeth T and adhering the back surface of the main body 11 across the surfaces of the adjacent teeth T, the bracket main body 11 itself is adhered to the teeth T in a familiar manner as in the first embodiment. At the same time, it is possible to continuously and reliably fix the adjacent teeth T of the patient,
Particularly, in the second embodiment, the bracket body 11
Since there is no protruding portion on the rounded surface side, there is less concern about giving the patient discomfort or discomfort. Also in the second embodiment, it goes without saying that improvement in aesthetics can be expected by the molding material and coating of the main body 11.

Further, the bracket for oral surgery according to the third embodiment will be described. This third embodiment is also developed from the same viewpoint as the above-mentioned second embodiment. As shown in FIG. 4, this time, the flat surfaces 15 that can be held by forceps or tweezers are positively formed on both sides of the bracket body 11, and the flat surfaces 15 on both sides are used as gripping portions. It is what was done. The other structure is the same as that of the first embodiment.

Therefore, when the bracket for oral surgery according to the third embodiment is used, this time, while the flat surfaces 15 on both sides are gripped by forceps or tweezers, the ridges formed on the back surface of the main body 11 are used. If the back surface of the main body 11 is adhered across the surfaces of the adjacent teeth T by aligning 12 with the corresponding depressions between the teeth T, the bracket main body 11 itself is adhered to the teeth T. At the same time, it is possible not only to continuously and reliably fix the adjacent teeth T of the patient, but, like the second embodiment, there is no protruding portion on the rounded surface side of the bracket body 11. Since it disappears, there is less concern about giving the patient discomfort or discomfort.

Finally, the bracket for oral surgery according to the fourth embodiment will be described. In contrast to the above-mentioned embodiments, the body 11 is bonded to the tooth surface by using forceps or a bracket. In the fourth embodiment, the bracket main body 11 is bonded to the tooth surface by using a dedicated mounting jig. For this reason, in this fourth embodiment, as shown in FIG. 5, a mounting jig 17 having a grip portion 18 and a support portion 19 is separately prepared, while the grip groove 16 is provided in the central portion on the front surface side of the main body 11. And the mounting jig 17 is formed in the grip groove 16.
The bracket main body 11 can be easily gripped by inserting the support portion 19 of the bracket 11 through the dedicated mounting jig 17.

Therefore, in the fourth embodiment, while holding the bracket main body 11 by the mounting jig 17, the protrusions 12 formed on the back surface side of the main body 11 are recessed between the corresponding teeth T. And the rear surface of the main body 11 is adhered across the surfaces of the teeth T adjacent to each other.
If the support portion 19 of the mounting jig 17 is removed from 6, the bracket body 11 is familiarly adhered between the teeth T, and at the same time, the adjacent teeth T of the patient are securely fixed between them, as in each embodiment. It becomes possible. In addition, even in this bracket, since there is no protruding portion on the rounded surface side of the bracket main body 11, there is less fear of causing discomfort or discomfort to the patient. Is exactly the same as the case. In the fourth embodiment, the gripping groove 16 and the supporting portion 19 of the mounting jig 17 can be formed in a cross shape, and the occlusal portion of the tooth T can be formed on the upper and lower portions of the gripping groove 16. Side and gum part side are marked,
It also means that the bracket body 11 can always be adhered in a correct posture.

In each of the above embodiments, the bracket body 1
1 is assumed to be adhered to the labial side of the tooth T, but it is also possible to adhere 1 to the tongue side of the tooth T for use. In this case, the back surface side of the main body 11 is provided with a curved surface shape adapted to the interdental shape on the lingual side.

[0021]

As described above, according to the present invention, even if the bracket body is formed of a colorless transparent material or a semi-transparent material, or even if it is formed of a metal material, the bracket body made of the metal material has teeth. Since it is characterized by having a crown color coating, unlike the conventional metal one,
Even if the patient opens his lips, it will not be seen by a third person as a dark one, which will contribute greatly to the improvement of aesthetics. In addition, since the front side of the bracket body is only rounded and does not have a hook body that protrudes considerably in the cheek direction as in the past, even if it is worn for a long period of time, the patient does not feel discomfort or discomfort. There is no need to worry about giving.
