The invention relates to a milling/grinding machine for the manufacture of dental-medical or dental-technical workpieces, having a workpiece receiver () and a tool () which can be moved, with respect to a workpiece () arranged in the workpiece receiver (), linearly along three axes (X, Y, Z) standing perpendicularly of one another. In order to provide a milling/grinding machine for highly exact and economic manufacture of medical, dental-medical and dental-technical prosthetic parts for the medical technician, dentist, dental assistant and the dental technician directly in the medical laboratory, practice or commercial laboratory, the tool () and the workpiece receiver () are each arranged rotatably and/or pivotably.

Milling/grinding machine for the manufacture of dental-medical workpieces

For the manufacture of shaped parts ( ) from ceramics, for example for dental-technical purposes, an assembly is provided which comprises a powdery ceramic raw material compressed to form a ceramic green compact ( ), an embedding mass ( ) which neither damages nor reacts chemically with the ceramic green compact ( ), and a holder or workpiece receiver ( ) which holds the embedding mass ( ) in a manner to allow the ceramic green compact ( ) to be machined while being embedded in the embedding mass.

Assembly for the manufacture of medical, dental-medical, dental-technical and technical parts from ceramics

The invention relates to a device for the optical measurement of dental objects ( ) with the use of topometric measurement procedures, having a rotatably mounted object receptacle ( ) for holding the object ( ) to be measured, a projector ( ) for the projection of structured lighting patterns onto the object ( ), a detection unit ( ) for the detection of lighting structures projected onto the object ( ), and an evaluation unit ( ) for the calculation of the spatial structure of the object ( ) to be measured. In order to improve operability, with the possibility of measuring individual parts of any geometry, the object receptacle ( ) is mounted so as to be additionally pivotable around a pivot axis (B) arranged perpendicularly to the axis of rotation (A).

Device for the measurement of dental objects

For the manufacture of shaped parts ( ) from ceramics, for example for dental-technical purposes, first of all a powdery ceramic raw material is compressed to form a ceramic green compact ( ). The inner contour and/or the outer contour of the shaped parts ( ) is then prepared by machining the ceramic green compact ( ) by means of eroding methods, with the ceramic green compact ( ) being embedded into a workpiece receiver ( ) before the Machining by means of an embedding mass ( ) which neither damages nor reacts chemically with the ceramic green compact ( ). Subsequently, the machined ceramic green compact ( ) is sintered to form a high-strength ceramic shaped part. A ceramic material which is almost shrinkage-free during sintering is preferably used.

Method for the manufacture of medical, dental-medical, dental-technical and technical parts from ceramics

In a process for cleaning and/or disinfecting and/or maintaining medical or dental instruments, in a washing container filled with liquid, particularly water, the at least one tool holder being washed internally and externally and additionally having ultrasound applied thereto, in the case of a hollow or sleeve-shaped instrument, particularly tool holder, the cavity of the instrument, in particular the cavity or cavities of the tool holder accommodating the mechanical drive elements, is drained and ultrasound is then applied to the tool holder.

Device for cleaning and/or disinfecting and/or maintaining medical or

In a device for selectively cleaning, disinfecting and maintaining medical or dental instruments, particularly tool holders, with a washing container to accommodate at least one instrument and with an ultrasonic cleaning device with an ultrasonic exciter which is arranged on the washing container, the washing container has a cross-sectional shape, preferably a horizontal cross-sectional shape, which deviates from a rectangular or square cross-sectional shape.

Process for cleaning and/or disinfecting and/or maintaining medical or

A process for the care or maintenance of medical and dental instruments and a maintenance locale or installation for implementing this process. The maintenance for the instruments, which is carried out in a single uninterrupted process cycle, and at a single maintenance locale facilitating all of the process steps.

Process for the care of medical and dental instruments and maintenance

An equipment stand, in particular for dental implements, which consists of a carrier possessing holders for the dental implements or instruments. A stand which extends in a vertical direction, concurrently forms the carrier possessing the implement holders, so as to thereby eliminate a separate component as a carrier in the form of a cross-bar, and consequently avoids a complex construction. Furthermore, through a superimposed arrangement of the implement holders there is afforded a good overview of the implements which are located in the holders.

Equipment stand, particularly for dental implements

A workplace for the treatment or finishing of, in particular, dental workpieces; for instance, impressions, dentures, plastic teeth, or respectively artificial teeth, and the like. Furthermore, the workpiece can also serve for the finishing of jewelry workpieces or the like by goldsmiths. An artificial background is used for the workplace in which there is clarified the coloration or, in essence, the color distinctions of the workpieces which are to be treated, through the avoidance of disturbing optical influences.

Workplace for the treatment, in particular, of dental workpieces

A work location for the processing or finishing of workpieces, includes a protective plate movable through the intermediary of a holder from a protective work position screening the operating person into a non-screening parked position, wherein a braking device is associated with the holder for maintaining protective plate in a predetermined position.

Work location for the processing of workpieces

An equipment stand for dental implements, consisting of a support column mounting holders for the implements, wherein the holders are horizontally reciprocable; in effect moveable to and fro. The horizontally reciprocable holders facilitate that the mostly different kinds of implements which are positioned in the holder can be brought into a suitable nearness for gripping at the working location of the dental technician, and pursuant to need; for instance, for the creation of the free space which is necessary for carrying out any such work which is to be done without the above-mentioned implements, can be again moved away from proximity to the gripping location.

Equipment stand for dental implements

A work position or station including a suctioning device incorporating a suctioning opening for the aspiration of suctionable material which is produced during the processing of workpieces, and a protective plate which guides the suctionable material into the suctioning opening. The protective plate concurrently screens the working personnel carrying out the processing, in particular the head of the person, against the incident suctionable material. The protective plate which is carried by a special mounting support can be moved upwardly prior to the implementing of work without the formation of suctionable material, upwardly away from the suctioning opening in a simple manner into a non-hindering inoperative position.

Work station with suctioning device

A worktable, in particular a dental laboratory workbench which includes a work block arranged at front side of the table, and a vacuuming device forming a unitary structure with the work block for vacuumable material or waste which is obtained during the processing or finishing of workpieces.
