CARTRIDGE, A PISTON AND A SYRINGE COMPRISING THE CARTRIDGE AND THE PISTON

摘要

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.
