Abstract

【課題】　細かい凹凸の部分など、必要な場合には健全な象牙質でも切削できるが、健全な象牙質を切削しているときは、そのことを術者に感知させることができるステンレススチールバーを提供する。 【解決手段】　基端側にハンドピースに着脱自在に結合される柄部１１を有し、先端に歯を切削するための刃の付いた作業部１２を有し、該作業部と前記柄部との間を、テーパー状の中間部１３で接続している。このスチールバーは、オーステナイト系ステンレススチールを伸線加工により加工硬化させ、ファイバー状組織としたものである。前記作業部を回転して健全象牙質を切削したとき、前記テーパー部が撓んで振動が生じることで、健全な象牙質を切削していることが分かり、削りすぎを防止することができる。また、前記作業部の最大径から先端部をエッチング等により処理して、刃先を丸くし、健全な象牙質に対しては切れ味を悪くして、削りすぎを防止することもできる。
