ろも精確に処理できる。<Effect of the device> As the scraping part of the curved tip of the dental hand tool of the present invention has fine ultra-fine particles such as diamond and hard ceramic sintered body attached to form fine unevenness, When cutting teeth such as removing tartar, or when peeling the mucous membrane of bone, the contact friction of the contact surface is very large,
Therefore, it bites well during operation, and it is possible to cut or peel off only the removal target portion quickly and sufficiently by being caught. Moreover, it is possible to accurately handle even the finest parts that cannot be done with a handpiece using a manual tool or the like in any case.
また、掻き取り部の前記凹凸面は軟質組織部分である歯

ていることから商品価値も高いなどの効果を奏する。Furthermore, since ultra-hard particles such as diamond and hard ceramics are used, they have excellent abrasion resistance, corrosion resistance and durability, and this ultra-hard particles are electrodeposited. Therefore, unlike the conventional one in which the metal surface of the scraping portion is processed to give a file-like unevenness, metal fatigue of this metal surface, that is, a crack is less likely to occur, and therefore the tip is not easily broken. Since it has excellent mechanical strength, it has effects such as high commercial value.
