本考案は、歯冠補綴架工義歯などの歯科補綴物
を研摩する際に用いられる研摩用回転ブラシの改
良に関するものである。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to an improvement of a rotating polishing brush used for polishing a dental prosthesis such as a crown prosthesis or bridge denture.

A rotating brush for polishing a crown or prosthetic denture such as a bridge or metal bond is a rotating brush made of wood or synthetic resin material in the shape of a thick disk, as shown in Figures 3 and 4. Base A
Brush bristles C are planted in one or more rows at a predetermined pitch on the circumferential surface B of the rotary base A, and in the center of the rotating base A, a chuck D at the tip of a lathe rotating shaft is fitted from the front to the back. A mounting hole E is provided for mounting.
（考案が解決しようとする問題点）
ところが、従来のこの種の研摩用回転ブラシ

隙などを研摩する際に、注意して作業しないと、
回転基体Ａの周面の両側縁部ａが周囲の研摩して

り、虫歯の原因となる。こうした事態は、ブラシ
の毛が刷り切れて短くなつた場合に特に顕著であ
る。(Problem to be solved by the invention) However, with this type of conventional rotating polishing brush, care must be taken when polishing the ridges or grooves of dentures, the drum-shaped spaces between teeth, etc. If you don't,
Both side edges a of the circumferential surface of the rotary base body A come into contact with surrounding areas that should not be polished, thereby ruining the denture. For example, in the case of an inlay, if the side edge a of the rotating base A hits and scrapes the so-called margin at the boundary between the metal and the tooth, the margin will be scratched or stepped, and food debris will be deposited in this area. It accumulates and causes tooth decay. This situation is particularly noticeable when the bristles of the brush are worn out and shortened.
これを解消するには、回転基体周面Ｂの幅を狭
くするのも一考であるが、そうすると、回転基体
Ａ自体の厚みも小さくなり、レーズのチヤツクＤ

従来の回転ブラシでは、チヤツクＤを嵌め込むに
必要な厚みの回転基体Ａを採用せざるを得ず、い
きおい前記したような研摩作業上の困難さを招来
することになる。 In order to solve this problem, one idea is to narrow the width of the rotating base circumferential surface B, but if this is done, the thickness of the rotating base A itself will also become smaller, and the lasing chuck D will be reduced.
The length of the mounting hole E into which the rotary brush is fitted becomes shorter, making the mounting of the rotating brush itself unstable. For this,
In the conventional rotating brush, it is necessary to adopt a rotating base A having a thickness necessary to fit the chuck D, which leads to the above-mentioned difficulty in the polishing operation.
また、このようにして回転基体Ａの厚みを所要

Ａの背面から付き抜けてしまい、使用時にこの先
端がブリツジや有床義歯にあたつてこれらを傷つ
ける結果にもなつている。 In addition, in the case of a rotating brush in which the thickness of the rotating base A is set to a required size in this way, in reality it is still not possible to secure a sufficient contact area between the outer circumference of the chuck and the inner circumference of the mounting hole. Not only will this result in unstable installation, but if the chuck D is repeatedly attached and detached, the tip of the chuck D will quickly stick out from the back of the rotating base A, which may cause the tip to become attached to the bridge or denture during use. The heat has also resulted in damage to these objects.

することにある。 In view of these problems of the prior art, the purpose of the present invention is to prevent polishing work from being hindered by the edges on both sides of the rotating base, to be able to securely and stably attach it to the chuck of the lathe, and to make it easy to attach and detach. To provide a rotating brush for polishing a dental prosthesis, in which the tip of the chuck does not easily penetrate through the back surface of a rotating base even after repeated brushing.
