摘要： A root canal treatment instrument 100 continues drive of a cutting tool 5 in forward rotation drive until reaching 180 degrees, and when a load applied to the cutting tool 5 is equal to or greater than a reference load, drive of the cutting tool 5 is switched to reverse rotation drive until reaching 90 degrees. In the root canal treatment instrument 100, when a cumulative amount of rotation is equal to or greater than a reference amount of rotation, change to a drive pattern is made, forward rotation drive is continued until reaching 90 degrees, and when a load applied to the cutting tool 5 is equal to or greater than the reference load, drive of the cutting tool 5 is switched to reverse rotation drive until reaching 180 degrees.

摘要： A data processing apparatus includes: an input portion configured to receive IOS data and CT data as an input, the IOS data being obtained by performing scanning by an intra oral scanner and including coordinate data of a point group indicating a surface shape of a tooth row including an IOS crown and an IOS gingiva, the CT data being obtained by performing capturing by a CT imaging device and including volume data of a CT crown; and processing circuitry. The processing circuitry replaces, in the CT data, a crown part of a CT tooth included in the CT data with which a shape of the IOS crown matches, with the IOS crown included in the IOS data, and performs synthesis in such a way that the IOS gingiva is arranged near the IOS crown after replacement.

摘要： In a medical system, a medical device includes a first display that displays a figure or a character corresponding to data relevant to medical treatment performed in the medical device, and a first controller that causes the first display to display the figure or the character corresponding to the data and that, when the data satisfies conditions for notification of a warning, causes the medical device to emit a first warning. A remote control device includes a second display that displays the figure or the character corresponding to the data, and a second controller that causes the second display to display the figure or the character corresponding to the data and that, when the data satisfies the conditions for notification of the warning, causes the remote control device to emit a second warning that is different than the first warning.

摘要： A data processing apparatus that includes an input interface to which three-dimensional data including position information of each point of a point group indicating a surface of at least one object is input; and processing circuitry that is configured to process the three-dimensional data that is input from the input interface. The processing circuitry is configured to process two-dimensional data from the three-dimensional data, identify a predetermined object among the at least one object based on the two-dimensional data, and extract predetermined three-dimensional data including the position information of each point of a point group indicating a surface of the predetermined object that is identified.

摘要： A dental treatment apparatus includes: a handpiece including a head that holds a cutting tool; a drive unit capable of performing forward rotation driving for rotating the cutting tool held at the head in a cutting direction, and reverse rotation driving for rotating the cutting tool held at the head in a non-cutting direction; an operation receiving unit that receives an operation of an operator; and a controller that controls the drive unit that drives the cutting tool, according to the operation received by the operation receiving unit. Only when a prescribed condition is satisfied, the controller sets the operation received by the operation receiving unit as an operation to drive the cutting tool by reverse rotation driving, or as an operation to drive the cutting tool by twist driving by which the forward rotation driving and the reverse rotation driving are alternately performed.

摘要： A dental treatment apparatus according to the present invention includes a drive unit that includes a micromotor, a motor driver, and the like, a controller, and a root canal length measurement circuit. The controller controls the cutting tool to be held at a head forward driven in a direction of cutting of an object to be cut. The controller also controls the cutting tool to be reverse driven in a direction reverse to forward rotation drive when the cutting tool is forward driven and the root canal length measurement circuit detects a tip end of the cutting tool reaching a reference position. The controller further carries out a fail-safe control when the cutting tool is reverse driven and the root canal length measurement circuit detects movement of the tip end of the cutting tool toward a root apex position.
