The present invention provides a mixer for producing a past by mixing components. The mixer includes a housing having a longitudinal axis, a rear end, and a front end provided with a discharge opening. The mixer also includes a mixing changer formed in the housing, where the mixing chamber has an entry side facing the rear end of the housing. The initial content of the mixing chamber is diverted from the discharge opening, and the subsequent content of the mixing chamber is extrudable from the discharge opening.

Mixer for multi-component pastes, kit, and method of mixing paste components

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 preferably directed to a dispenser of the type sold by 3M ESPE under the trade name Pentamix and as also described above. Such a dispenser preferably comprises at least a first and a second compartment for a first reservoir and a second reservoir, respectively, the first and the second reservoirs containing a first and a second component for the dental material, respectively. It further preferably comprises a first and a second plunger driven by a first drive for advancing the first and the second components from the first and the second reservoirs, respectively. Moreover, a dynamic mixer driven by a second drive for automatically mixing the first and second components to form the dental material from the first and second components is provided. Such a dispenser further preferably has a dispensing portion or mixing tip for dispensing the mixed dental material. The present invention is more particularly directed to a dispenser or method adapted for advancing and mixing at least one dental material, comprising at least one drive which is operated on a predetermined, non-uniform drive speed profile. Preferably an advancing speed profile is provided for advancing the components and/or a mixing speed profile is provided for mixing the components, and either profile may be a 'drive speed profile' as that term is used herein. More preferably both profiles are provided.

Dispenser and method for dispensing dental material

A dental impression tray is provided having a wall including at least one retaining element. The retaining element at least partially overhangs an associated passageway, wherein the passageway extends between first and second wall surfaces that face in different directions Further, methods and molds to form a dental impression tray according to the invention are provided and a kit including a plurality of such dental impression tray.

Dental impression tray

A method of making a dental blank comprises the steps of independently compacting a first and second zone of a quantity of ceramic particles. During compacting, the first and second zones have different compaction factors in at least one stage. Such blanks may be pre-sintered and used in the manufacture of dental restorations. The method may help in controlling the homogeneity of the material structure during manufacturing the blanks.

The present invention relates to a method of mixing and dispensing viscous materials, comprising the steps of: inserting a cartridge containing one or more viscous materials in a chamber; activating a first motor () to move a plunger from a first position to a second position within the cartridge and activating a second motor () to move the plunger from the second position further within the cartridge to dispense the material.

The present invention provides a mixer for producing a paste by mixing components, comprising a housing having a longitudinal axis, a rear end, and a front end provided with a discharge opening; and a mixing chamber formed in said housing and having an entry side facing said rear end of said housing. The initial content of the mixing chamber is diverted from the discharge opening, and the subsequent content of the mixing chamber is extrudable from the discharge opening.

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.

Frame containing ceramic block for producing dental crowns and bridges

The invention relates to a dynamic mixer for mixing at least two paste components of different volume proportions. Said mixer comprises a housing with at least two inlet openings and at least one outlet opening, a mixer element being rotatably mounted in a mixing chamber of said housing. The housing has at least one delay chamber comprising a limiting wall that blocks the paste stream in the direction of flow and at least one opening that opens into the mixing chamber, said opening(s) being set back in relation to the limiting wall. The mixer is particularly suitable for mixing paste components with a relatively high viscosity of, for example, greater than 800 Pas.

Dynamic mixer

The invention relates to a method for the determination of the patient-related risk of caries by determination of lactic acid and/or lactate in saliva and to a method for the location-specific determination of the patient-related risk of caries.
