摘要： The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); a driving state detecting unit (resistor for load detection, root canal length measuring circuit); and a controller. The hand piece drivably holds a cutting tool on a head unit. The power source drives the cutting tool. The driving unit drives the cutting tool with twist driving in which the normal rotation and the reverse rotation are repeated. The driving state detecting unit detects a driving state of the cutting tool. The controller changes at least one parameter of a rotation angle in the normal rotation, a rotation angle speed in the normal rotation, a rotation angle in the reverse rotation, and a rotation angle speed in the reverse rotation in accordance with the driving state of the cutting tool detected by the driving state detecting unit.

摘要： A dental treating apparatus according to the present invention includes: a hand piece; a head unit; a driving unit; a control unit; a load specifying unit; and a load comparing unit. The hand piece drivably holds a cutting tool on the head unit. The driving unit drives the cutting tool in a normal rotation direction or in a reverse rotation direction. The load comparing unit compares a load detected and a reference load. During a normal rotation period until driving for rotating the cutting tool in the normal rotation direction by the driving unit satisfies a predetermined first condition, the control unit maintains a rotation direction of the cutting tool in the normal rotation direction, and when a result of comparison by the load comparing unit attains a predetermined result during the normal rotation period, the control unit controls the rotation direction to the reverse rotation direction.

摘要： The present invention is directed to a dental treating apparatus including: a hand piece; a power source (micro motor); a driving unit (motor driver); and a controller. The driving unit drives the cutting tool so as to be switchable between first driving in which the cutting tool is driven clockwise and second driving in which the cutting tool is driven counterclockwise. When a rotation direction in which the cutting tool cuts an object to be cut is defined as normal rotation and a rotation direction opposite to the normal rotation is defined as reverse rotation, the controller sets the first driving as driving for the normal rotation when a first cutting tool rotated clockwise is held on the head unit, and sets the second driving as the driving for the normal rotation when a second cutting tool rotated counterclockwise is held on the head unit.
