A training system includes a tool connected to a control module. The tool includes a tip and a grip having two or more force sensing transducers configured to enable determination of sensor force measurement data. The control module receives the sensor force measurement data. The control module includes a storage device configured to store zeroed force data, and a data processing unit including a processor and memory storing instructions that, when executed by the processor, cause the processor to obtain the sensor force measurement data and the zeroed force data; determine, based upon the sensor force measurement data and the zeroed force data, a load force magnitude that is independent of grasp forces; determine whether the load force is within a set range; and, provide a corresponding indication where the load force is within the set range and/or where the load force is outside of the set range.

A method for promoting compliance with an oral hygiene regimen includes displaying, on a display device, a representation of at least a portion of a set of teeth of a user. The method also includes overlaying an indicium on the representation such that the indicium is associated with a first section of the representation. Responsive to a determination, via at least one of one or more processors, that a head of an oral hygiene device is positioned directly adjacent to a first section of the set of teeth that corresponds to the first section of the representation for at least a predetermined amount of time, the indicium is removed from the display device.

A plate to be used by being fixed to a stent to be mounted on a row of teeth of a patient includes a plurality of CT markers, a detachable part that is configured to connect a reference frame, provided with a plurality of infrared markers whose relative positional relationship with the respective CT markers when the reference frame is connected to the plate is known, and a recessed part that is configured to be used in measuring registration accuracy between position coordinates of the CT markers in a three-dimensional reconstructed CT image including the plate as an object and position coordinates of the CT markers in real space in which the plate exists, the position coordinates being calculated on the basis of the position coordinates of the infrared markers.

A dental simulation machine including a support having a support surface for engagement by a finger of a user to support a hand of the user, the support surface being moveable between a plurality of positions.

The system according to the invention comprises: a handpiece, to which an endodontic instrument can be connected that is intended to be inserted into a root canal, a measurement unit for measuring a magnitude related to the position of the endodontic instrument in the root canal and a computation and display unit for displaying a graph representing the evolution of the magnitude measured by the measurement unit during an endodontic treatment with the endodontic instrument. The method according to the invention comprises the following steps: displaying, by means of a computation and display unit, a graph representing the evolution of a magnitude measured during a root canal treatment performed by the dentist, the magnitude being related to the position of an endodontic instrument in the root canal, and providing a reference graph representing a predetermined endodontic treatment technique to allow a comparison to be made between the graph representing the evolution of the measured magnitude and the reference graph.

A dental treatment training apparatus allows practice of complex treatments involving high accuracy and skill levels. A dental treatment training apparatus for providing a simulated treatment in which a treatment instrument is applied onto a tooth model includes a display unit that displays, in a superimposed manner, 3D image information based on predefined 3D information about the tooth model and the treatment instrument on a 3D view image, a position detector that detects 3D positional information about the tooth model, the treatment instrument, and the display unit, and a control unit that causes the display unit to display, in a superimposed manner, 3D image information corresponding to an item selected on a superimposed selection operation display for allowing selection of an item associated with the simulated treatment based on the 3D positional information detected by the position detector.

A system for visual analysis of a virtual medical model, particularly for medical product development and/or for anatomical comparison by multiple users, comprises a means for providing a virtual medical model and a visualization means, for generating a view and/or a scene of the virtual medical model. The visualization means sends image data representing the generated view and/or scene to a display means. The view-manipulation means allows a user to manipulate a view of the virtual medical model, receives a user input, and translates the user input in vision change data of the virtual medical model or a sub-model thereof. A synchronization means receives and synchronizes the received vision change data and transmits synchronized vision change data to the visualization means. The view-manipulation means receives the synchronized vision change data and based on the received data updates the view and/or a scene of the virtual medical model.

[Object] To provide, for a composite resin (CR) having a wide range of applicable colors (shades) (wide-ranging color applicable CR), such as a CR having light diffusion properties and a CR that produces color by means of a structural color, a technology with which an excellent effect, specifically, an increased breadth (number) of applicable shades in comparison to an existing CR other than a wide-ranging color applicable CR, can be achieved. [Solving Means] For example, in a demonstration instrument, a plurality of samples is prepared, a single wide-ranging color applicable CR has been used to restore a cavity in artificial teeth each having a different shade, the cavity being formed at a predetermined position of the artificial teeth, and the plurality of samples is disposed side by side and fixed on a display surface of a display plate, thereby making it possible to compare/contrast conditions of restored portions of the samples to each other and the color tone applicability thereof to those of a teeth to be restored.

An anatomical model of a maxilla of a living being, including a gingiva representing the maxilla of said living being, the anatomical model having at least one guide for a tool integrated into the gingiva to allow an operator to simulate a dentistry gesture.
