摘要： A root canal therapy device with a mechanical vibration mode and a rotation drive mode includes a head, a handle, a first flexible drive shaft and a second flexible drive shaft. The head includes an outer main part, a mandrel part for mounting a root canal file, a first drive input shaft part and a second drive input shaft part. The mandrel part is mounted in the outer main part. A first drive motor and a second drive motor are disposed on the handle. The invention has the following beneficial effects: the root canal file can rotate and vibrate during root canal preparation, so that the wall of a root canal is efficiently cut by the file; and the file can also vibrate, so that cutting resistance and cutting temperature are effectively reduced, a smear layer is avoided, and the quality and efficiency of root canal preparation are improved.

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： Provided is a system for endodontic treatment of a root canal. The system includes a handpiece containing a rotary motor adapted to rotate an endodontic file secured by the handpiece. A control unit executes a regime of motion of the motor to produce a regime of file motion in which episodes of oscillation of the file are separated by a rotation of the file. When the arc of a rotation is less than the arc of the oscillation that preceded the rotation, the arcs of the episodes of oscillation overlap and the formation of ridges in the root canal is avoided.

摘要： An apparatus for controlling asymmetrical coasting of an endodontic reciprocating motor includes a controller operatively connected to the endodontic motor. The controller may include a processing unit that is configured to direct the rotation of the endodontic motor in the forward direction for a coast time and configured to direct the rotation of the endodontic motor in the reverse direction for a coast time. The forward coast time is separately calculated from the reverse coast time. A method for asymmetrically coasting a reciprocating endodontic motor includes rotating an endodontic motor in a forward direction and calculating a forward coast time for the forward direction and coasting the endodontic motor in the forward direction for the calculated forward coast time. After coasting the endodontic motor in the forward direction, the endodontic motor is rotated in a reverse direction. The reverse coast time is different than the forward coast time.
