摘要:
The invention relates to an intra-oral camera having an imaging system for depicting the object located in front of an observation window of the camera on a recording unit, wherein the imaging system has at least one focusing unit for setting a suitable focus and an aperture unit for forming a variable aperture. The setting of the aperture is carried out independently of the focus adjusted by the focusing unit.

An electronic register device for recording movements of the lower jaw of a person relative to the upper jaw of the person, the device having a bite fork for recording a position of the upper jaw relative to reference points on the head of the person, wherein the bite fork is designed to receive a plastic compound for recording an impression of the dentition of the upper jaw
摘要:
A system for producing dental moldings from blanks, having a machine tool for machining a blank, and a workpiece holder for securing the blank during machining. The machine tool has in this case a mount for the workpiece holder, and the workpiece holder has a shank region that can be inserted reversibly into the mount and in the inserted state can be secured in position in the mount. Furthermore, the system has a lever element, wherein the system is configured so that the lever element can be clamped between the mount on one side and the shank region on the other side to secure the shank region in position in the mount. With such clamping of the lever element, a particularly high clamping force can be produced, by way of which the shank region of the workpiece holder can be secured in position in the mount.
摘要:
A motor-driven handpiece, which has a grip sleeve with a head area for mounting a tool, in particular for the preparation of tooth substance and/or bone substance, in which the head area is at least partially surrounded or encapsulated by a thermoplastic material which, compared to the material of the rest of the grip sleeve, has a lower thermal conduction value.

A medical, in particular dental, diagnostic device having means for image capture and a hand piece that has a window located in the optical path of the means for image capture, wherein there are means for heating the window formed by a resistance heater.
摘要:
The invention relates to an electric-motor arrangement for a medical, in particular dental, hand piece which has a motor housing (2) and a rotor (4) which is arranged in the motor housing (2) so that it can be rotated about an axis (L) via a first bearing (6) and a second bearing (8). A stator (14) is arranged around the rotor (4) in relation to the axis (L). The first bearing (6) is received in a first bearing flange (10), and the second bearing (8) is received in a second bearing flange (12). Both bearing flanges (10, 12) are composed of metal and adjoin the motor housing (2) directly by way of their circumferential faces (101, 121). As a result, running noise and vibrations can be reduced. Moreover, premature wear and/or failure can be prevented.
摘要:
In a dental, dental-medical or dental-technical handpiece, having an elongate grip sleeve there are provided at the rearward end of the grip sleeve coupling elements for the connection of the handpiece to a supply hose to be connected with a dental supply arrangement, and there are provided at the forward end of the grip sleeve a head section with a tool receiver for mounting a tool to be put into rotation. The handpiece further has an electric motor for driving a tool held by the tool receiver, which motor is completely integrated into the grip sleeve such that grip sleeve and motor form a unit.
