An artificial denture-skull for dental teaching and practice purposes, consisting of the model of an upper jaw which is equipped with teeth and of the model of a lower jaw which is equipped with teeth, the lower jaw model being connected with the upper jaw model for pivotal movement through the intermediary of two jaw linkages which are arranged at respectively both sides of the jaw models, whereby the lower jaw model is presently equipped with an articulated ball belonging to the jaw linkages and which is guided within an articulating track arranged in an articulating box on the upper jaw model. For the most possible exact simulation of the human head, the denture-skull can also be provided with a cerebral skull portion, as well as with a pocket-shaped covering possessing an oral or mouth aperture, for the resultant formation of a complete phantom head.

An artificial denture-skull for dental teaching and practice purposes, consisting of a model of an upper jaw or maxilla equipped with teeth and with a model of a lower jaw or mandible equipped with teeth, the last of which is pivotally connected with the upper jaw model through two jaw linkages which are arranged at both sides of the jaw models whereby for fixing the denture-skull in an open position, a downwardly extending latching device is provided on the upper jaw model and which able to be brought into engagement with the lower jaw model. For the most possibly complete simulation of the human head, the denture-skull is also connectable with a cranial cavity-forming skull portion, as well as with a pocket-shaped covering which possesses an oral aperture.

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 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.
