PROBLEM TO BE SOLVED: To install a cutting object body so as to cut a dental restoration at an uncut part of the cutting object body when installing the cutting object body on a CAM apparatus.SOLUTION: A cutting object body 1 for dental CAD/CAD being installed on the CAD/CAM apparatus to manufacture a dental restoration, the cutting object body for the dental CAD/CAM has a substantially columnar shape, and includes at least one recess 2 at a circumference part of the cutting object body for the dental CAD/CAM. The recess has a portion 4 not covering the entire circumference of the cutting object body for the dental CAD/CAM, and when the cutting object body for the dental CAD/CAM is installed on the CAD/CAM apparatus, the recess is engaged with the CAD/CAM apparatus.SELECTED DRAWING: Figure 1COPYRIGHT: (C)2018,JPO&INPIT【課題】被切削体をCAMに設置する場合に、被切削体の切削されていない部分で歯科修復物を切削加工できる様に設置する。【解決手段】CADCAM装置に装着して歯科修復物を製造する歯科用CADCAM用被切削体1において、歯科用CADCAM用被切削体が略円柱形状であり、歯科用CADCAM用被切削体の円周部に少なくとも一つの凹部2を有し、凹部は歯科用CADCAM用被切削体の全周に亘っておらない部分4があり、CADCAM装置に歯科用CADCAM用被切削体を装着時に凹部が係合することを特徴とする歯科用CADCAM用被切削体である。【選択図】図1
