摘要:
The invention concerns methods and a device for the determination of the centric position of a human set of teeth with improved precision. This is needed for the adjustment of an articulator in the production of dentures. For this purpose a plurality of successive bite movements or displacement movements of the lower jaw are recorded in form of electronic signal data and evaluated for the determination of the centric position.

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:
A container for use with a hand-held device, in particular for dental purposes, for dispensing a pasty filling compound, the viscosity of which can be reduced by supplying vibration energy, wherein the container is designed to receive the pasty filling compound and comprises a discharge opening at the front end for dispensing the filling compound. The discharge opening is formed by a cannula which is made of steel, for example. The viscosity of the filling compound can be positively influenced by the cannula. In this way, in particular a significant increase in the liquefaction degree of the filling compound can be achieved.
摘要:
An electric motor arrangement for a medical, especially dental, tool handle, which is extremely compact and resistant to sterilizing temperatures due to a plurality of advantageous embodiments. The electric motor arrangement is characterized by the following properties: the use of a light source based on SMD-LED or LED as a semiconductor chip; the shortening of the INTRAmatic coupling to between 20 mm and 25 mm; a hermetically extruded stator comprising integrated media tubes and molded connection sockets; the stator winding is embodied as a coil segment winding instead of an H winding or triangle; and the winding head has openings for media tubes.

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.

Device and method for disinfecting, sterilizing, and/or looking after medical, in particular dental, instruments, comprising a rinsing chamber in which there are holders for receiving the instruments, wherein at least parts of the walls of the rinsing chamber or elements located in the rinsing chamber can be cooled.
摘要:
A device for packaging and dispensing several fluid products includes at least two sealed flexible gags arranged in a single rigid container, associated with at least one pump, the rigid container consisting of an open cylinder and the bags are provided each with a pump and a push button, and are mounted opposite on each of the two opposite openings of the cylinder. The device is applicable to appliances containing fluids to be dispensed independently of one another.
摘要:
A bearing for rotatably mounting a rotational part, for example a turbine rotor of a dental handpiece, has a plurality of roll bodies, in particular balls, arranged between an inner bearing ring and an outer bearing ring, a cage surrounding the roll bodies in an axial direction, and a locking element for axially locking the bearing rings with respect to each other, wherein the locking element has a ring-like or ring-segment-like securing element fitted on an inner circumference of the outer bearing ring or on an outer circumference of the inner bearing ring in a region of the cage such that the locking element blocks the roll bodies in the axial direction.
摘要:
A system for driving an electric handpiece in response to a pneumatic control signal may provide for fast interchange of handpieces, self-calibration and wide dynamic range of operation with precise speed control. The system may be incorporated into virtually any dental treatment center using traditional pneumatic drive handpieces, and a conversion kit may facilitate such conversion. The system may provide not only for controlling the speed and torque of a tool coupled to an electric drive handpiece responsive to a pneumatic control signal, it may also provide for coupling cooling air and treatment media, such as air and/or water to the handpiece. Coupling of a handpiece to an operating base of the system, including coupling of media lines and electrical connections may be made with a simple press and twist action using quick connection structure.
