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.
