Abstract: 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.

Abstract: 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.

Abstract: A cap mountable on and detachable front an intraoral scanner including a housing having an opening for connecting to at least a part of the intraoral scanner, a measurement window provided in the housing and located opposite to the opening, and a mirror that reflects light from the measurement window toward the opening. The housing has a longitudinal length shorter than that of a probe defining a depth-of-field, of the intraoral scanner extending from the measurement window to a predetermined extent.

Abstract: A dental observation device by which, without displaying, in an overlapping manner, a visible light image of an image-capturing site in an oral cavity captured by a 3-D camera and 3-D image information on the image-capturing site in the oral cavity acquired in advance, an invisible portion in the visible light image is easily recognized.An observation system includes a visible light 3-D camera; a relative position calculator; a 3-D information storage storing 3-D image information acquired in advance; an image display displaying, side by side, a 2-D captured image captured by the visible light 3-D camera and 2-D converted image based on the 3-D image information corresponding to the surgical operation target site; and a display direction adjuster displaying, in the image display, the 2-D converted image in a predetermined direction on the basis of the image-capturing direction detected by the relative position calculator.

Abstract: An X-ray CT scanner generates CT imaging information I on an imaging region CA. The X-ray CT scanner 1 includes a revolution arm 30 locating an X-ray generator 10 and an X-ray detector 20 such that the X-ray generator 10 and the X-ray detector 20 face each other while having a subject M1 therebetween;an XY table 35 moving the revolution arm 30 such that an irradiation direction of an X-ray cone beam Bx is offset from the center of the imaging region CA; an axial direction changing mechanism 43 changing the imaging target from a first imaging region R1 to be processed by the imaging first to a second imaging region R2 in a Z-axis direction; a main body controller 60 controlling the X-ray CT imaging; and a stitch image information generator 861b generating stitch imaging information Is. The main body controller 60 is configured to be capable of executing control on the XY table 35 and the offset CT imaging, and control on the axial direction changing mechanism 43 to generate first CT imaging information I1 and second CT imaging information I2. The stitch image information generator 861b generates the stitch imaging information Is from offset CT imaging information Io based on the first CT imaging information I1 or the like acquired by offset CT imaging.

Abstract: A three-dimensional scanner for obtaining shape information of an object body includes a light source unit, a varifocal unit, a reference unit, a light path length adjustment unit, an optical sensor, and a control unit. The varifocal unit is able to change a focal position, and both of light from the light source unit to the optical sensor via an object body and light from the light source unit to the optical sensor via the reference unit travel at least once. The control unit determines a condition of varifocal unit based on light has been reflected on reference unit and detected by a part of optical sensor, and calculates the shape information of the object body from light detected by the optical sensor using information of the condition of the varifocal unit that has been determined.
