The invention relates to a dynamic mixer for viscose components in particularfor the mixing of dental compositions, with a rotor (30) and a housing(2), which has front inlet openings (12, 13) for the components and atleast one rear outlet opening (20) and the inner space of which includes apre-chamber (17) and a main chamber (22), with the pre-chamber (17)opening into the main chamber (22) in a distal, tapering transition section(16). For the precise regulation of the concentration of the components tobe mixed of the supplied components even with temporary concentrationfluctuations of the same and in order to achieve a high degree ofhomogenization,it is proposed that the dynamic mixer (1) has at least one individualchannel (23a-d) as a passage from the pre-chamber (17) into themain chamber (22), with the width of the individual channel (23a-d) extendingover a part of the periphery of the transition section (16).
