A syringe for dispensing a flowable material. The syringe has a cartridge with a cartridge front end and at least a first dispensing nozzle arranged at the cartridge front end. The syringe further has closure for openably closing the first dispensing nozzle. The closure includes a cap and at least a first seal. The cap is telescopically placeable on the cartridge front end. The closure or the cartridge has a first magnet for establishing a magnetic attraction between the closure and the cartridge. In a situation in which the closure is placed on the cartridge front end, the closure and the cartridge can be positioned in a sealing position in which the first seal spaces the cap and the cartridge front end away from each other against a magnetic attraction that urges the cap and the cartridge toward each other.

A cartridge and a piston for storing and dispensing a two-component dental material. The cartridge and the piston have a cross-section which substantially correspond to a D-shape in which the perimeter of the D-shape is defined by a plurality of circle segments only. At least two of the circle segments are based on different radii. The invention helps maximizing the time period over which a dental material can be stored in the compartment.

A method of layerwise building up an object from at least a first and a second light hardenable resin on a 3D printing device, and a 3D printing device that is configured to perform such a method. The 3D printing device has a build platform on which the object can be built up, a light-transmissive carrier comprising a plurality of recesses and a light projector for projecting a light-pattern through the carrier. The method has the steps of (a) partially building up the object and thereby providing an object-in-process; (b) coating a first surface area of the carrier with a first blank layer of the first light hardenable resin; (c) moving the carrier and thereby positioning the first blank layer between the build platform and the light projector; (d) bringing the object-in-process into contact with the first blank layer; (e) irradiating the first blank layer with a light pattern and thereby supplementing the object-in-process by a hardened layer; and (f) separating the supplemented object-in-process from the carrier.

Dosage dispenser

A mixer assembly with a static mixing element arranged within a mixing channel. The mixer assembly has an inlet end, for receiving components of a substance and a dispensing end for dispensing a mixture from the components. The inlet end comprises for each component an inlet and an associated non-return valve. Each of the inlets is connectable for fluid communication with the mixing channel via the associated non-return valve.

Mixer assembly and device for dispensing a dental material

A dispenser has a bottle () and a closure () for the bottle (). The closure () has abase () forming a dispensing outlet () and a flip-cap for openably closing the dispensing outlet (). The base () is attached on the bottle (). The dispenser () further having a hinge () which interconnects the flip-cap and the base () for swiveling the flip-cap relative to the base () between a closed position, in which the flip-cap closes the outlet (), and an open position in which the outlet () is open. The hinge () forms a swivel axis. The closure () forms a first end () in a direction toward the flip-cap and a second end () in a direction toward the base (). The closure () in an area between the hinge-level plane and the second end () forms an outer surface circumferentially around the longitudinal axis which is at least partly provided by an outer surface of the base () and an outer surface of the flip-cap.

A system which has a static mixer and which contains a dental material. The static mixer has a mixing barrel that extends along a longitudinal axis and, accommodated therein, a cascade of mixing elements. Mixing elements have an outer diameter D of between 1.5 mm and 1.6 mm. The barrel has an inner diameter corresponding to the outer diameter of the mixing elements. The system helps minimizing any residual dental material in the mixer and minimizing forces for extruding the dental material through the mixer.

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

A capsule for mixing and dispensing a dental material which has a capsule body and a cavity extending into the capsule body. The cavity is closed by a liquid container. The liquid container has a cartridge forming a channel that extends between a front opening and a rear opening of the cartridge. Further the cartridge has a front foil closing the front opening and a rear foil closing the rear opening. The front foil is attached at the cartridge along a closed path circumferentially around the front opening. The front foil and the cartridge in at least a partial area of the circumferential path are separably sealed with each other, thus defining an openable valve through that path. The capsule has further a piston received in the channel of the cartridge and arranged such that the liquid is enclosed in the cartridge between the front foil and the piston. The capsule facilitates the preparation of a two-component dental material.

A container for storing and dispensing a liquid has a generally cup-shaped receptacle formed by a circumferential side wall and a front wall. A piston is slidably accommodated within the receptacle. The receptacle and the piston in combination form a chamber in which the liquid is received. The piston forms a sealing structure bearing on an inner surface of the side wall. The inner surface of the side wall has an arithmetic average surface roughness of between 0.05 &#x3bc;m and 4.5 &#x3bc;m R?a.#191 The container allows for air to penetrate in the chamber while it provides for the liquid to be captured therein.

Container for storing and dispensing a liquid

A plunger assembly for a cartridge for dispensing dental material. The plunger assembly has a receptacle, an activator, and a passageway extending through the receptacle along a longitudinal axis. The passageway forms a chamber for storing at least a component of the dental material and has an outlet for the chamber. The activator has a piston for extruding the component from the chamber and a plug for the outlet. The activator is movable to unplug the outlet and to subsequently extrude the component in a single stroke. The plunger assembly helps for reliably emptying the chamber and helps facilitating dispensation of dental materials.

Plunger assembly and a capsule for dispensing a dental material

A device for dispensing a dental material comprises a container for containing the material and an outlet which is closed by a closure. A breakable seal is arranged between the closure and the container. The device further is operable between a storage position in which the outlet is closed and an operational position in which the outlet is open. An initial operation toward the operational position causes the seal to break, whereby the closure is captured in the device. The device may provide a relatively long shelf life for the material, and may facilitate preparation of the material for use.

A nozzle head () for a powder jet device () for use in applying dental material, the nozzle head () comprising: a first portion () and a second portion () transitioning into one another; the first portion () adjacent a first end () of the nozzle head () having a coupling () for removably connecting the nozzle head () to a hand piece () of the powder jet device (); the second portion () adjacent a second end () of the nozzle head () forming a nozzle outlet () for the dental material; the second portion () comprising at least a first fluid channel () which is formed between the nozzle outlet () and a channel inlet (); wherein the channel inlet () is arranged at the transition () between the first portion () and the second portion () between the nozzle outlet () and the coupling ().
