It is designed to effectively perform this process and to prevent the spray from scattering inside and outside the mouth during tooth surface polishing.

射効率が必ずしも高くなく、集中噴射にやや欠け
るものがあつた。 Conventionally, when using a tooth surface polishing device to remove plaque and stains adhering to the tooth surface by spraying a mixed spray of water and abrasive onto the tooth surface, the tip of the suction tube was separately attached near the spray nozzle. It is designed to suck up and collect scattered water and abrasives.
Because there was a lot of scattering, things didn't go as planned.
The particles were scattered inside and outside the mouth, staining the dental treatment table and the dentist's hands, which required cleaning after the fact, which was a nuisance. In addition, especially due to the structure of the spray nozzle, the spray efficiency of the mixed spray of water and abrasive to a specific tooth surface was not necessarily high, and there were cases where concentrated spray was somewhat lacking.

法について種々検討した結果、本考案を見出すに
至つた。 Here, the inventor of the present invention has conducted various studies on methods for effectively spraying the spray onto the tooth surface and easily preventing the spray from scattering inside and outside the mouth when using such a tooth surface polishing device. I came to find out.

る。 That is, the present invention has a notched tip that is used by fitting into the tip of the spray nozzle of a tooth surface polishing device that sprays a mixed spray of water and abrasive onto the tooth surface to remove and clean deposits on the tooth surface. It is an object of the present invention to provide a tooth surface polishing injection nozzle attachment made of a soft tubular body.

高温殺菌も可能な利点がある。 The injection nozzle attachment uses a soft tubular body with a part of the tip cut out in a V-shape or U-shape, and the tubular body is fitted to the tip of the injection nozzle to form an integral unit. Since it is made of a soft material, the tip fits comfortably against the tooth surface without any discomfort, and this allows the spray to be concentrated on a specific location on the tooth surface. After the polishing process is completed, the spray is discharged from the notch in the tubular body, and most of it is removed outside the mouth by a suction tube waiting nearby. As the soft tubular body, it is more convenient to be able to see the part of the tooth surface to be polished, so it is preferable to use transparent silicone rubber, for example.
It also has the advantage of being able to be sterilized at high temperatures.
以下、実施例により本考案をさらに具体的に説

に、Ｖ字状の切欠き２を形成している。 As shown in FIG. 1, an injection nozzle 3 is provided on a hand piece 4 via a bent pipe section 5 in the tooth surface polishing apparatus. A short soft tubular body 1 made of transparent silicone rubber is fitted into the injection nozzle 3, and the tip of the soft tubular body 1 has a V-shaped notch 2 as shown in FIG. is forming.
切欠き２の方向は、歯科治療で慣用される吸引
管の先端開口に切欠き２が接するように、任意に
位置決めをすることができる。 The direction of the notch 2 can be arbitrarily positioned so that the notch 2 contacts the tip opening of a suction tube commonly used in dental treatment.

飛散を防止する。 Approximately 2.0 to 2.2 Kg/cm2 of pressurized air and 2.0 Kg/cm2 are supplied from the soft tubular member 1 through the injection nozzle 3 so that the soft tubular member 1 is in contact with the tooth surface area to be polished.
Pressurized water and an abrasive agent such as sodium bicarbonate are sprayed at a rate of 4 to 5 g per minute to polish and clean the tooth surface. During this time, a suction tube is also used to prevent the spray from scattering.
