An identification apparatus includes an input interface to which position data including position information of each of a plurality of objects is input, and processing circuitry that is configured to identify at least one object among the plurality of objects based on the position data that is input from the input interface and an estimation model that is trained to estimate a type of each of the plurality of objects based at least on the position data of each of the plurality of objects, the position data including a relative positional relationship which is fixed inside the mouth.

A dental handpiece is a dental handpiece configured to drive a cutting tool to rotate the cutting tool. The dental handpiece includes: a head configured to accommodate the cutting tool rotatably, a first bearing provided on an insertion side on which the cutting tool is inserted into the head, and configured to hold the cutting tool rotatably, a second bearing provided on a side opposite to the insertion side of the head and configured to hold the cutting tool rotatably, and a driving mechanism configured to rotate the cutting tool held by the first and second bearings. The first and second bearings each have a cage to hold balls, each cage being formed of a different material.

A support apparatus supporting a procedure using a dental implant including a plurality of members. The support apparatus includes: input processing circuitry configured to acquire three-dimensional data representing a three-dimensional geometry of an interior of an oral cavity including teeth forming a dentition and a jawbone; computing processing circuitry configured to determine a position for each of the plurality of members in the oral cavity based on the three-dimensional data acquired by the input processing circuitry, and adjust the determined position of at least one of the plurality of members based on a positional relationship between the plurality of members; and output processing circuitry configured to output support information representing a position for each of the plurality of members after the adjustment performed by the computing processing circuitry.

A radiation image scanner is a radiation image scanner that reads a radiation image from a front surface of an image plate (IP), and includes a stage that supports the IP from a back surface side and a setting guide including a first IP guide surface that guides the IP obliquely downward. At least one of the setting guide and the stage includes an inclined surface (second IP guide surface), which is a surface inclined downward to the opposite side with respect to the first IP guide surface, receives the IP guided by the first IP guide surface, and guides the IP obliquely downward. At least one of the stage and the setting guide includes a front-back inverting portion that comes into contact with the IP from a front surface side of the IP to invert the IP to the same inclined posture as the inclined surface.

A dental handpiece includes a main body portion, a holding portion, and a releasing mechanism. The releasing mechanism includes a cap, a cap ring, and a push cap. The cap includes an outer annular portion and an inner annular portion provided with at least one window portion. The push cap is configured to be movable to a releasing position between the outer annular portion and the inner annular portion in a direction in which the push cap is put on the cap ring, the releasing position being a position at which the holding portion is released. The cap ring includes at least one claw portion anchored to the at least one window portion from the inner side. The at least one claw portion is disposed on the inner side with respect to the inner annular portion.

An image processing apparatus that includes a storage storing image data obtained by CT imaging of dentition constituent tissue, a processor, and a display. The processor generates three-dimensional image data of the dentition constituent tissue, identifies a segmentable region in the dentition constituent tissue, identifies a three-dimensional position of the segmentable region, generates a dentition developed image, identifies a segmentable region corresponding position corresponding to the three-dimensional position in the dentition developed image, and displays, on the display, the dentition developed image in which the segmentable region is displayed at the segmentable region corresponding position. By designation of the segmentable region corresponding position, on the basis of a correspondence between the segmentable region corresponding position and the three-dimensional position, a detail observation image of the segmentable region is generated, and a detail observation reference position is determined according to a predetermined rule.

An image processing apparatus that displays, on a display, a biological feature region arrangement developed image in which at least one of a plurality of annotation images respectively indicating a plurality of biological feature regions is superimposed on a dentition developed image such that the annotation images are located at corresponding positions of the plurality of biological feature region corresponding positions. Detail observation images at the plurality of three-dimensional positions are respectively generated on the basis of the three-dimensional image data, a focus order of the plurality of biological feature regions is determined according to a predetermined rule, and when the biological feature region arrangement developed image is displayed, it is indicated that the biological feature regions are subjected to focusing in the focus order by a change in the annotation images and the detail observation images corresponding to focusing of the biological feature regions are displayed on the display.

An image processing apparatus having a processor and a display that displays an observation image. The processor generates three-dimensional image data of the dentition constituent tissue, detects a biological feature region in the dentition constituent tissue, identifies a three-dimensional position, generates a dentition developed image in which the dentition constituent tissue is developed, identifies a biological feature region corresponding position corresponding to the three-dimensional position in the dentition developed image, displays, on a display, a biological feature region arrangement developed image in which an annotation image indicating the biological feature region is superimposed on the dentition developed image such that the annotation image is located at the biological feature region corresponding position, generates a detail observation image at the three-dimensional position on the basis of the three-dimensional image data, and displays the detail observation image simultaneously with the biological feature region arrangement developed image on the display.

A microscope for medical diagnosis and treatment that allows an observer to view a natural stereoscopic image of an object to be observed. The microscope for medical diagnosis and treatment includes an objective optical system, imaging circuitry, a display, and an eyepiece optical system configured to direct light of the displayed image from the display element to an observer. The objective optical system includes first and second objective optical systems, the first and second objective optical systems are arranged to form a convergence angle by respective optical axis of the first and second objective optical systems, the number of horizontal or vertical pixels of the display element is 2000 or more and 4000 or less, and an angle of view of the eyepiece optical system is 35 degrees or more and 60 degrees or less.
