Dental material applicator with partitioned packaging

The present invention is directed to a plunger, a plunger assembly, and a system for storing a substance or substances, preferably flowable substances, and a method of filling and sealing a substance in a storing system. In particular, the present invention provides for substantially air-free filling and storing of substances in a delivery system.

Plunger and plunger assembly for a cartridge, system for storing a substance, and method of filing and sealing a substance in a delivery system

A device for use in retracting a gingiva from a human tooth by widening a gingival sulcus with a dental composition. The device comprises a cannula with a free end having an opening for dispensing the dental composition. The free end is shaped to be inserted with its front in the entry of the gingival sulcus, and to laterally displace the gingiva from the tooth as the cannula is moved in the gingival sulcus. The invention may help to achieve a reliable and cost effective gingival retraction treatment.

Device and a method for delivery of a dental composition

Plunger and plunger assembly for a cartridge, system for storing a substance, and method of filling and sealing a substance in a delivery system

A dispensing device for a dental substance which has a container for receiving the dental substance, a piston movable in the container, a catch for engagement by an applicator, and further a resilient resilient adapter. The device may be used in different types of applicators and is relatively inexpensive.

Device for a dental substance

Provided is a capsule for storing and dispensing dental material. The capsule comprises a cartridge for the dental material, and a nozzle. The nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material. One of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, wherein the bearing member and bearing shell form a pivot. Upon pivoting the nozzle from the first to the second position, the seal between the bearing member and the bearing shell is improved.

Device for dispensing material

A method of making a dental workpiece is provided. The method comprises the steps of suspending machining of the workpiece, exposing the workpiece to a first air jet; and causing relative movement between the first air jet and the workpiece under numeric control. The method may facilitate manufacturing of dental workpieces.

Method and device for making a dental workpiece

A dispensing cartridge, particularly for dental impression materials, formed from a plastic material having at least one inlet and at least one outlet, and including a metal reinforcement tube.

Dispensing cartridge

The present invention is directed to a package assembly for placing it on a surface and for storing and/or delivering substances, preferably dental substances, comprising: at least one container with at least one base and at least one lid; and at least one hinge connecting the base and the lid; wherein the base and the lid comprise at least a first and second lever; the first and second levers are provided at the container essentially on the side of the hinge and; a projection of the first lever onto the surface and the second lever extend with their free ends essentially in a direction away from the hinge; and wherein the container can be opened or the lid can be removed from the base by moving the ends of the first and second lever towards to each other. The invention is further directed to a method for providing dental substances, a kit with an assembly, as well as the use of an assembly and a method for storing and/or delivering dental substances.

Package assembly for dental substances

Capsule () for two or more components of a material which are to be mixed together, comprising a cartridge () comprising an outlet (), a first component chamber () for containing a first component, and a second component chamber () for containing a second component, the two chambers () opening into the outlet (); and a piston () which at least with its front end sits in the cartridge (), lies with its rear end outside the component chambers () and, when it is pushed forwards, presses the two components out of their component chambers ().

Capsule for two-component materials

A capsule for storing and dispensing dental material. The capsule comprises a cartridge for the dental material, and a nozzle. The nozzle being pivotable with respect to the cartridge between a first position in which the capsule is closed for storage and a second position in which the capsule is opened for dispensing the dental material. One of the nozzle and the cartridge comprises a bearing member and the other one of the nozzle and the cartridge comprises a bearing shell, wherein the bearing member and bearing shell form a pivot. Upon pivoting the nozzle from the first to the second position, the seal between the bearing member and the bearing shell is improved.

A device for handling workpieces. The device has a magazine () for holding at least one workpiece, and a delivery location (). The device is retainable in the magazine by a retainer (s) () in the delivery location and displaceable to a position in which the workpiece because of its shape releases the retainer (s) so that the workpiece is free for being removed from the magazine. The device may provide for easy handling of workpieces and may be manufactured cost effectively.

Device and system for handling of dental workpieces

The present invention relates to a syringe for storage, mixing and dispensing of multi-component paste materials, and more precisely to a syringe for two or more components of a paste material which are to be mixed together. The syringe may be activated so that the chambers containing the components are opened, and the components may be mixed together and extruded through a mixing tip.
