Abstract: An application device with a cylindrical basic body for storing a squeezable dental material having a piston positioned inside the basic body and axially displaceable towards the basic body. A piston rod serves to displace the piston in the squeezing direction, which piston rod partially reaches into the piston and is axially displaceable towards the latter. The piston is provided with an elastic resetting device at its front end area positioned in the direction towards the dental material. The elastic resetting device can be biased in the squeezing direction, and returns back to its relaxed position after the end of each axial movement of the piston in the squeezing direction and release of the pressure exerted on the piston rod for this purpose.

Abstract: This invention relates to a blank arrangement, with a blank (22) that is to be machined, in particular for the production of dental restoration parts. The blank is connected to a holder (16), which is fixedly connected to the blank (12), and to an adapter (22), which releasably bears the holder (16) and the blank (12), the adapter (22) having an effective surface by means of which the blank unit can be mounted in or on the work holding fixture of a machining device.

Abstract: The invention relates to an application device for dental materials with a cartridge that has a piston and is destined for receiving the dental material, and with an application nozzle that is attached to an outlet port of the cartridge. A positive or form-fit connection between the cartridge (12) and the application nozzle (14) is formed, and the application nozzle (14) and/or the cartridge (12) have a vent duct (40) whose width or diameter prevents or blocks the dental material from flowing out.

The elastic resetting device can be biased in the squeezing direction, and returns back to its relaxed position after the end of each axial movement of the piston in the squeezing direction and release of the pressure exerted on the piston rod for this purpose. Dripping of excess dental material is prevented from the application device by creating a partial vacuum inside the basic body, with the elastic resetting device pressing the piston rod in a direction opposite the squeezing direction.

Abstract: A cartridge for storing and applying a mass, especially a mass of dental material, includes a tube-shaped base body having a first cylindrical portion and a second bent portion and an extrusion spout. A load engaging element cooperates with an extrusion drive device that can be activated to perform an extrusion operation in which the mass in the cartridge is extruded from the extrusion spout. The cartridge also includes an axially displaceable piston disposed in the base body and operable to be displaced by operation of the extrusion drive device such that the piston, as it moves relatively within the first cylindrical portion and the second bent portion of the base body, pushes the mass out of the base body into the extrusion spout and therebeyond. The inner diameter of the extrusion spout is smaller than the inner diameter of the base body and the piston is at least partially bendable.

Abstract: An application apparatus for facilitating the application of a substance on an application location by a substance transfer element includes a base body, a first receptacle supported on the base body for retaining therein a fluid which can react with another material composition to form the substance to be applied, and a second receptacle supported on the base body. The second receptacle receives and retains therein the substance transfer element during stockage of the application apparatus. During a substance applying use, the substance transfer element is removed from the second receptacle with the material composition releasably retained on the substance transfer element, inserted into the first receptacle for reactive contact of the material composition with the fluid into the first receptacle to form the substance to be applied, removed from the first receptacle, and put in contact with the application location such that the substance is transferred to the application location.

Abstract: A syringe for dental material has a cylinder with a dispensing socket and an open end opposite the dispensing socket. A plunger is inserted through the open end into the cylinder and is guided in the cylinder. The plunger is made of a porous, sintered material.

Abstract: A syringe for dispensing a viscous material has a cylindrical housing with a first and a second end. An outlet member is connected to the first end of the cylindrical housing. A deformable dispensing body is slidable in the cylindrical housing from the second end to the first end for dispensing the viscous material in a dispensing direction of the syringe. The deformable dispensing body is insertable into the outlet member and deformable to the shape of the outlet member, but has a dimensionally stable trailing end.
