Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a reinforcing material for dental treatment, which is made of a resin such as a composite resin which is hardened by light rays and is used for dental treatment such as repairing a defective tooth and fixing a moving tooth.

[0002]

2. Description of the Related Art Conventionally, as such a reinforcing material for dental treatment, for example, a fiber glass knitted into a string shape or a band shape (trade name "GlasSpan") is disclosed in US Pat. No. 5,098,304. Known by. In this prior art, when fixing an artificial tooth to a healthy tooth to repair a missing tooth, a reinforcing material is formed so that both ends of a reinforcing material (glass pan) formed in a string shape or a belt shape protrude from both ends of the artificial tooth. And the artificial tooth are integrally formed, and the groove into which the protruding glass pan is fitted is formed in the meshing surface of the healthy teeth on both sides of the defective tooth, and the glass pan is fitted into this groove, and the silane coupling is performed. After the adhesive and the bonding agent are applied and the composite resin is applied thereon, the composite resin is irradiated with light rays to be cured.

Further, in the case of dental treatment such as fixing of oscillating teeth, fixing of teeth by orthodontics, fixing of dislocated teeth and the like, those which form a groove for fitting a glass pan to a healthy tooth and those which do not form this groove There is. That is, the method of forming the groove is the surface of the healthy tooth to be fixed (front side or back side (lingual side) surface)
A groove for arranging the glass pan is formed in the glass pan, the glass pan is arranged in this groove, the silane coupling agent and the bonding agent are applied, and the composite resin is applied on the groove. Is a permanent fixing method of semi-permanently fixing the teeth. The method in which the groove is not formed is a temporary fixing method in which a glass pan formed in a string shape or a band shape is directly fixed to the back side of a healthy tooth to be fixed by a composite resin and temporarily fixed.

[0004]

However, in the above-mentioned prior art, since the reinforcing material is formed by knitting only the fiberglass, the reinforcing material is formed into a thick string in order to secure the strength required as the reinforcing material. Or it is necessary to knit in a thick band.

Therefore, when the conventional technique is applied to dental treatment, when a groove is formed in a sound tooth for fixing a reinforcing material, it must be formed deeply, and it takes a long time to form it as compared with a case where it is formed shallowly. It takes a long time, and moreover, careful treatment is needed so as not to damage the dental nerve.
In addition, the range of dental treatment that can be performed is limited, and for example,
When using a glass pan for an indirect bridge, in which protrusions are formed in advance on artificial teeth with reinforcing materials and fixed to the occlusal surfaces of healthy teeth on both sides of the missing tooth, ensure the necessary strength as a reinforcing material. Therefore, since the thickness of the protruding portion becomes thicker, the groove for fitting the protruding portion is formed deeply, which damages the healthy teeth, and there is a problem that the use of the glass pan for the indirect bridge is restricted. It was In addition, if the conventional technique is applied without damaging the healthy teeth, the groove is formed shallow and the glass pan is arranged, and therefore, the thick portion of the glass pan protrudes from the groove. However, there are problems such as unnaturalness, damage to various internal organs such as the tongue and lips, and difficulty in pronunciation. Further, if the thickness of the glass pan is thin, the strength required as a reinforcing material is weakened, so that there is a problem that the fixing life is short. Furthermore, when a glass pan is fixed without forming a groove in a healthy tooth, the thickness of the glass pan makes the tooth prominence unnatural, which makes the tongue feel uncomfortable and damages various organs in the oral cavity. There was a problem that it was difficult to pronounce.

[0006] The present invention has been made in view of such conventional problems, and is a dental treatment in which the strength of the reinforcing material is improved, the range of practicable dental treatment is expanded, and the treatment time is shortened. It is intended to provide a reinforcing material for a car.

[0007]

In order to achieve the above object, the reinforcing material for dental treatment of the present invention is formed by braiding carbon fiber thin fibers and fiber glass thin yarns in a string shape. Further, the thin fiber of carbon fiber and the thin fiber of fiberglass are knitted in a band shape.

[0008]

Since the thin fiber of carbon fiber and the thin fiber of fiberglass are formed by knitting, the strength of the reinforcing material is improved, and in the case of a string shape, even if the thickness of the reinforcing material is thin, In this case, even if the thickness of the reinforcing material is thin, the strength required as the reinforcing material is secured.
