  • Crown prosthesis preparing system, crown prosthesis preparing method, and non-transitory storage medium storing program for preparing crown prosthesis
    Patent number: 10172694
    Abstract: A crown prosthesis preparing system includes a data generator and a cutting device including a retainer, a cutting mechanism, and a controller. The cutting mechanism includes a first processing tool that cuts a workpiece to form a processed workpiece, a second processing tool that polishes the processed workpiece, a driver detachably holding at least one of the first processing tool and the second processing tool and controlling its position. The controller includes a first control section causing the first processing tool to cut the workpiece retained by the retainer based on three-dimensional data, to form the processed workpiece, and a second control section causing the second processing tool to polish a surface of the processed workpiece retained by the retainer based on the three-dimensional data.
