Dental instrument

A process for taking a dental impression and/or conducting a dental retraction. The process includes the steps of:

Process for taking a dental impression and curable composition for use in a dental impressioning and retraction process

The invention features a composition which can or is to be used in a dental retraction, the composition comprising liquid a liquid and a layer type 1:1 silicate mineral and a layer type 2:1 silicate mineral in a ratio from about 50/50 to 5/95 wt.-% with respect to each other. The invention also relates to a container containing the dental retraction composition and to a kit comprising parts A and B, wherein part A comprises the dental retraction composition and part B comprises at least one accessory selected from the group of applier, dental impression material, retraction cap(s), a container for storing and dispensing the composition and combinations thereof. The invention further features a process of dispensing a dental retraction composition, the process comprising the steps: providing a dental retraction composition contained in a container, placing the container in an applier, and using the applier for dispensing the dental retraction composition out of the container.

Dental retraction composition, method of production and use thereof

A device for dispensing a material has a container for holding the material, a piston movably arranged within the container and a spindle in cooperation with the piston. The device is configured such that the spindle and the container are rotatable relative to each other to move the piston for dispensing the material. The piston and the spindle are adapted to anti-twist lock against each other in a first axial position of the piston relative to spindle. And in a second axial position of the piston relative to spindle the anti-twist lock between the piston and the spindle is suspended. The device helps minimizing any residual dental material upon attempting to empty the device.

Device for dispensing a material

A capsule for mixing and dispensing a dental material which has a body forming a cavity. The cavity is closed by a liquid container. The body and the liquid container in combination form a mixing chamber containing a first component of the dental material. The liquid container has a cup-shaped cartridge formed by a cartridge front wall and a cartridge side wall and having a rear opening. A plug is movably joined within the cartridge through the rear opening for extruding a liquid second component of the dental material. The cartridge further has a channel extending through the cartridge side wall for releasing the second component into the mixing chamber. The body side wall inwardly has a recess being dimensioned for establishing a fluid communication between the channel and the cavity in an activated position, where the activated position corresponds to a second axial position of a two different axial positions of the of the cartridge and the body relative to each other. Further the first axial position corresponds to an inactivated position in which the channel is offset from the recess. A first cover film seals the joint between the cartridge and the plug, and the channel is openably sealed by a second cover film at least in the inactivated position. The capsule helps facilitating the preparation of a dental material.

Capsule for mixing and dispensing a dental material

A pen-like dispenser for dispensing a dental material has a handle and a cover which are attached for rotation relative to each other about a longitudinal axis of the dispenser, and a cartridge for holding the dental material and a screw plunger for extruding the dental material from the cartridge by screwing action. The cartridge and the cover in combination form a rotary slide valve which is operable by rotation about the longitudinal axis between a storage position, in which the cover closes a dispensing outlet of the cartridge, and a dispensing position, in which an opening in the cover opens the dispensing outlet of the cartridge. A relative rotation between the screw plunger and the handle about the longitudinal axis is restricted, and a relative rotation between the cartridge and the cover about the longitudinal axis is enabled within a predetermined rotation angle and restricted otherwise.

Pen-like dispenser for a dental material

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

A powder jet device () for dispensing a dental material comprises a nozzle head () comprising a discharge nozzle. The powder jet device () further comprises a housing () comprising a valve portion (), which is connected to the nozzle head () and is adapted to receive a valve member (), and a chamber portion () comprising at least a first chamber () for storing a powder material. The chamber portion () comprises a proximal end () located adjacent the valve portion (), a distal end () located away from the valve portion () and a fluid channel () extending from the distal end () substantially to the proximal end () into the chamber. The powder jet device () further comprises a valve member () disposed within the valve portion (). The valve member () comprises a fluid supply passage () and is movable between a first position, in which a first fluid path () for delivery of a fluid from the fluid supply passage () into the chamber via the fluid channel () so as to create a dispersion from the powder material and a second fluid path () for delivery of the dispersion to the discharge nozzle are open, and a second position, in which at least the first fluid path () is closed.

Powder jet device for dispensing dental material

Provided is a cartridge assembly comprising a cartridge for containing a dental substance. The cartridge comprises a dispensing opening for the dental substance. Further the cartridge assembly comprises a piston having a receptacle for establishing a screw connection with a spindle for moving the piston for dispensing the dental substance. This assembly helps minimize costs in the manufacturing and use of dental cartridges and/or dental dispensing devices.

Cartridge for dispensing a dental substance and method of assembling the cartridge

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

A device for dispensing a dental substance. The device includes a cartridge for containing the dental substance. The cartridge has a plunger, and a dispensing opening. Further the device is operable to urge the dental substance toward the dispensing opening. The device further includes a cutter for cutting off a portion of the dental substance which protrudes over the dispensing opening. The device may particularly facilitate precise dispensation of a high viscosity dental substance.

Device for dispensing a dental substance and method of dispensing

The present invention relates to a capsule for storage, mixing and dispensing of materials, preferably dental materials like glass ionomer cement. The capsule comprises a capsule body member that provides a main chamber and comprises a dispensing opening; and an applicator member being slideably accommodated in said capsule body member, said applicator member providing an auxiliary chamber. An activator member is slideably accommodated in said applicator member.
