Description

Dental Burs {BUR USED DENTISTRY}

The present invention relates to a dental bur, and more particularly, to a dental bur for smoothly forming the outer peripheral surface of the fixture exposed to the outside during implant placement.

Dental burs rotate at low or high speeds during dental treatment to remove or polish the dentin and enamel of teeth, or parts of artificial teeth made of metal or ceramic, as well as various types of metals, ceramics and other hard It is used for cutting and drilling the material.

Dental implants are substitutes for restoring lost human tissue. In dentistry, artificial teeth are made after implanting and fixing fixtures to alveolar bones where natural roots have been removed to replace the roots (roots) of lost teeth. It refers to a substitute to fix to restore the original function of the tooth.

Such dental implants can be classified in various ways according to the method of coupling the artificial tooth and the root. Among them, there is a screw type implant, which utilizes the bonding force of the screw, and a conventional screw type implant assembly is composed of a fixture, abutment, and a prosthesis.

Here, the fixture is placed in the alveolar bone serves to fix the entire implant system.

Screws are formed on the outer circumferential surface of the fixture, and when the upper part is exposed during placement in the alveolar bone, there is a problem of increasing plaque deposition on the exposed area of the screw and thus causing diseases such as inflammation of the gums, and the risk of failure of the implant procedure. There is an increasing problem.

An object of the present invention is to provide a dental bur which can prevent the deposition of plaque and lower the risk of failure of an implant procedure in a fixture exposed to the upper surface of the alveolar bone.

Dental bur of the present invention is a body portion hollow is formed therein; A coupling part formed on the body part and detachably coupled to the dental handpiece to receive rotation force from the dental handpiece; And a polishing part formed below the body part, having a hollow formed therein, and the outer circumferential surface of the fixture inserted through the opened lower portion in contact with the inner circumferential surface to polish the screw formed on the outer circumferential surface of the fixture by rotation. Include.

The body portion is preferably formed with a plurality of viewing windows spaced apart at regular intervals.

The lower end of the grinding portion is a loud, it is preferable that the lowest point of the rounded portion is formed to be in contact with the gingiva or alveolar bone to minimize the inner side.

According to the dental bur of the present invention, by smoothly polishing the outer peripheral surface of the fixture exposed to the outside of the alveolar bone, the deposition of the plaque can be reduced by removing the screw formed on the outer peripheral surface of the fixture to provide a deposition environment of the plaque In addition, it also has the advantage of reducing the risk of implant failure.

Hereinafter, the dental bur of the present invention will be described in detail with reference to the accompanying drawings.

1 is a perspective view schematically showing a dental bur according to an embodiment of the present invention, Figure 2 is a schematic cross-sectional view showing a grinding portion of the dental bur of Figure 1, Figure 3 by the dental bur of Figure 1 A cross-sectional perspective view schematically showing the polishing of exposed fixtures to the outside.

1 to 3, the dental bur of the present invention is for polishing a portion exposed to the outside of the fixture 200 embedded in the alveolar bone during implant placement, the body part 110 and the coupling part 120. ) And the polishing unit 130.

The body part 110 may have a cylindrical shape having a hollow formed therein, and a lower portion thereof may be opened, and a plurality of viewing windows 111 may be spaced apart from each other at regular intervals.

Here, the viewing window 111 is formed in the shape of a hole in the side of the body portion 110 to be able to look inside from the outside.

The coupling part 120 may be integrally formed on the upper part of the body part 110 or may be in a combined shape, and the upper part is detachably coupled to a dental handpiece (not shown) to transmit rotational force from the handpiece. Receive.

The polishing unit 130 may be formed integrally or detachably coupled to the lower portion of the body portion 110, a hollow is formed inside, the upper and lower portions are opened, the upper portion of the body portion 110 And a fixture 200 to be polished is inserted into the lower portion.

The polishing unit 130 may be divided into three parts, an upper portion, a middle portion, and a lower portion. The inner horizontal width of the upper portion, that is, the aperture, is larger than the diameter of the lower portion, and the central portion connecting the upper portion and the lower portion is inclined. .

Here, the diameter of the upper portion may be formed of about 6 ~ 8mm preferably 6.1mm or 7.3mm, the diameter of the lower portion may be formed of about 4 ~ 7mm preferably 4.9mm or 6.1mm, the middle The inclination angle of may be formed at 45 degrees with respect to the horizontal line orthogonal to the bottom of the top.

On the other hand, the lower lower end of the polishing unit 130 may be formed convexly rounded downward, wherein the lowest point of the convex portion may be formed inclined inward.

The lower bottom of the polishing unit 130 is formed in this way, but the bottom is formed so as to be inclined toward the innermost position is the trauma to the alveolar bone or gingiva adjacent to the lower portion of the polishing unit 130 during polishing of the fixture 200. To reduce the addition of

The lower inner surface of the polishing unit 130 may be surface treated by diamond, green stone, white stone, brown rubber, or the like.

The dental bur having the structure as described above has the polished portion 130 coupled to the portion of the fixture 200 exposed to the outside of the alveolar bone, that is, the exposed portion of the fixture 200 is inserted into the polished portion 130. When the handpiece is driven in the state, the dental bur is rotated to polish the screw formed on the outer circumferential surface of the fixture 200 by the inner circumferential surface of the polishing unit 130 which is in contact with the outer circumferential surface of the fixture 200. The outer circumferential surface of the can be made to be smooth, that is to say in the form of a private.

According to the dental bur of the above structure, by smoothly polishing the outer peripheral surface of the fixture 200 exposed to the outside of the alveolar bone, the screw is formed on the outer peripheral surface of the fixture 200 to provide a deposition environment of the plaque This can reduce the deposition of plaque, and also has the advantage of reducing the risk of failure of the implant procedure.
