Description
本考案は、歯科医師及び歯科衛生士が歯周病治療及び予防などのために行う、歯科診療において、歯石・歯垢などの除去及び清掃などに用いられる作用部を構成する歯科用動力式スケーラーの先端に装着される歯科用スケーラーチップに関するものである。This invention relates to a dental scaler tip that is attached to the tip of a powered dental scaler that constitutes the working part used for removing tartar, plaque, etc. and cleaning in dental treatment performed by dentists and dental hygienists for the treatment and prevention of periodontal disease.
歯石や歯垢は、う蝕や歯周病等の原因となり、歯科医師、歯科衛生士においては、歯石・歯垢などの除去及び清掃などは、歯科治療で必須になっている。このような歯石・歯垢などの除去及び清掃などの治具としては、従来、把持部の先端に作用部が一体成形された歯科用ハンドスケーラー、歯科用動力式スケーラーとしては、電気を駆動媒体とする回転運動によりスケーラーチップの作用部を歯面などに作用させる電気モーターハンドピース、エアーを駆動媒体とする振動運動によりスケーラーチップの作用部を歯面などに作用させるエアータービンハンドピース、並びに同じく電気を駆動媒体とする超音波・音波振動によりスケーラーチップの作用部を歯面などに作用させる超音波・音波スケーラーなどを使用して、歯石・歯垢などの除去及び清掃などの作業を行っている。Tartar and plaque cause caries, periodontal disease, etc., and dentists and dental hygienists are required to remove and clean tartar, plaque, etc., in dental treatment. As tools for removing and cleaning tartar, plaque, etc., conventionally, dental hand scalers in which an action part is integrally formed at the tip of a grip part, powered dental scalers such as electric motor handpieces that cause the action part of a scaler tip to act on tooth surfaces, etc., by rotational motion using electricity as a driving medium, air turbine handpieces that cause the action part of a scaler tip to act on tooth surfaces, etc., by vibration motion using air as a driving medium, and ultrasonic/sonic scalers that cause the action part of a scaler tip to act on tooth surfaces, etc., by ultrasonic/sonic vibrations using electricity as a driving medium, etc., are used to remove tartar, plaque, etc., and to clean and remove tartar, plaque, etc.
従前においては、歯科用動力式スケーラーなどに装着される歯科用スケーラーチップはステンレス鋼などの様な耐蝕性、耐摩耗性に優れた金属で製造されているのが通例である。硬度の大きい金属で製造された歯科用スケーラーチップの場合には、作業過程におけるチップの摩耗が抑制されるとともに、短時間でも歯石などの付着物を効率よく除去できるので、歯科治療にとっては有効である。Conventionally, dental scaler tips attached to powered dental scalers and the like have usually been made of metals with excellent corrosion resistance and wear resistance, such as stainless steel, etc. Dental scaler tips made of metals with high hardness are effective for dental treatment because they suppress wear of the tip during the work process and can efficiently remove deposits such as tartar even in a short time.
しかし、硬度の大きい金属製の歯科用スケーラーチップは、歯などに当たると、歯などを損傷してしまうという問題が生じやすい。このように、歯などが損傷すると、その損傷部分に歯石や歯垢などが付着しやすくなり、新たに、う蝕や歯周病の原因を作ることになるため、歯科治療において、この様な損傷の発生を極力抑制することが望ましい。However, dental scaler tips made of metals with high hardness are prone to the problem of damaging teeth when they come into contact with them. When teeth are damaged in this way, tartar and plaque tend to adhere to the damaged area, creating new causes of caries and periodontal disease, so it is desirable to prevent such damage as much as possible in dental treatment.
特許文献１（特開２００３－３２５５５１）では、母材がステンレス鋼であり、加熱処理後の硬さがビッカース硬度でＨｖ３００～１２００であり、エナメル質（ビッカース硬度Ｈｖ３４３）とは、ほぼ同一の硬度以上で、象牙質（ビッカース硬度Ｈｖ６８）よりは、かなり硬い。In Patent Document 1 (JP 2003-325551 A), the base material is stainless steel, and the hardness after heat treatment is a Vickers hardness of Hv 300 to 1200, which is almost the same hardness as enamel (Vickers hardness Hv 343) and considerably harder than dentin (Vickers hardness Hv 68).
特許文献２（特開２０１５－１５９８８９）では、請求項に、スケーラー用チップの基端側が金属（ステンレス鋼など）で先端側が充填材非含有のポリエーテルエーテルケトン樹脂（十分な硬さを有してとあるが、硬度の記載は無い）で出来ているとし、歯牙にキズなどの損傷低減可能なスケーラー用チップとしている。In Patent Document 2 (JP 2015-159889), the claims state that the base end of the scaler tip is made of metal (such as stainless steel) and the tip end is made of filler-free polyether ether ketone resin (which is said to have sufficient hardness, but no mention of the hardness) and that the scaler tip can reduce damage such as scratches to the teeth.
特許文献３（特許３６４６７４８）では、チップ全体がポリマー材料に充填材を配合したものであることを特徴とし、母材は、ステンレス鋼などの金属とは、違うが、ロックウェル硬度（ＨＲＭ）が６５～１２０（ＨＲＭ６５以下だと振動エネルギーの減衰大、１２０以上だと治療対象個所の損傷・破折起こすとし）の成形体を得る歯科用チップの製造法であり、歯や人工的な修復、補綴物やインプラント材などを損傷することなく歯石などの付着物を除去するとしている。In Patent Document 3 (Patent 3646748), the entire tip is characterized by being made of a polymer material mixed with a filler, and although the base material is different from metals such as stainless steel, it is a method for manufacturing dental tips that obtains a molded body with a Rockwell hardness (HRM) of 65 to 120 (HRM of 65 or less results in significant attenuation of vibration energy, and HRM of 120 or more can cause damage or fracture of the treatment target area), and is said to remove deposits such as tartar without damaging teeth, artificial restorations, prosthetics, implant materials, etc.
上記のような従来の各種スケーラーの作用部として、ステンレス鋼などの加熱処理後の硬さを歯面のエナメル質の硬さモース硬度７程度、象牙質の硬さモース硬度６程度より硬くした金属を使用したり、若しくは、ダイヤモンド（モース硬度１０）等の細粒を電着させて、作用面を粗面にして使用されている。これらは効果的ではあるが、金属の硬さ及び、ダイヤモンドの硬さが大き過ぎて、歯面のエナメル質や象牙質を傷つけ易い難点があった。本考案は、これらの実情に鑑みなされたものであり、歯面などを傷つけることが出来るだけ少なくした歯科用スケーラーチップを提供するものである。As the working part of the above-mentioned conventional scalers, metals such as stainless steel are used, which are harder than the enamel of the tooth surface (Mohs hardness 7) and the dentin (Mohs hardness 6) after heat treatment, or fine particles such as diamond (Mohs hardness 10) are electroplated to make the working surface rough. Although these are effective, the hardness of the metal and the diamond are too high, and they have the drawback of easily damaging the enamel and dentin of the tooth surface. The present invention has been made in consideration of these circumstances, and aims to provide a dental scaler tip that damages the tooth surface as little as possible.
上記課題を解決するために、作用部を構成する歯科用動力式スケーラーの先端に装着される歯科用スケーラーチップであって、歯面に付着した歯石や歯垢などを除去する為の作用部を含み、その作用部のステンレス鋼などの金属の加熱処理後の硬さがモース硬度４～５であることを特徴とする。In order to solve the above problems, a dental scaler tip is provided which is attached to the tip of a powered dental scaler which constitutes an operating part, and which includes an operating part for removing tartar, plaque, etc. adhering to the tooth surface, and which is characterized in that the hardness of the metal such as stainless steel in the operating part after heat treatment is 4 to 5 on the Mohs hardness scale.
モース硬度が４未満であると歯石等の硬い汚れ除去に適さず、またモース硬度が５を超えると歯面の硬度との差が大きくなり過ぎ、歯面を傷つける可能性が大きくなってしまう。よって、歯科用スケーラーチップの作用部のステンレス鋼などの金属の硬さが、モース硬度で４～５になるよう加熱処理が施されることにより、歯石・歯垢などの除去及び清掃などの歯科治療を行う時に、歯面などを傷つけることが出来るだけ少なくできる。If the Mohs hardness is less than 4, it is not suitable for removing hard stains such as tartar, and if the Mohs hardness exceeds 5, the difference in hardness with the tooth surface becomes too large, increasing the possibility of damaging the tooth surface. Therefore, by subjecting the metal such as stainless steel of the working part of the dental scaler tip to heat treatment so that its hardness becomes 4 to 5 on the Mohs hardness scale, damage to the tooth surface can be minimized as much as possible when performing dental treatment such as removing tartar, plaque, and cleaning.
