The disclosure relates to a two-component mixing capsule for intake and for mixing of two compositions with a capsule housing having a discharge spout at its front end, wherein the mixing capsule comprises a first mixing chamber and a second mixing chamber, wherein the two mixing chambers may be separated from each other for storage or for transport, by the first mixing chamber being rotatable into a first position in which the first mixing chamber is separated from mixing chamber, by a rotatably mounted handhold element, the rotational axis of which is approximately perpendicularly arranged to the longitudinal axis of the mixing capsule. The two mixing chambers form a common mixing chamber by rotating the first mixing chamber into a second position in which the central axes of the first and second mixing chamber are substantially coaxially arranged, wherein the composition may be discharged after mixing by attaching a squeezing piston.

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.

Described herein is a dental material applicator system comprising a segmented capsule and handpiece. The capsule separately holds a powder and a liquid such that upon activation in the handpiece by an operator, the powder and liquid are mixed into a paste. The operator then triggers the handpiece so that the mixed paste is extruded.
