A mixer (120) for mixing components to form a dental material comprises a mixing rotor, first, second and third input connectors. Each of the first, second and third input connectors are adapted to form part of a plug-and-socket connection and are further adapted for plugging in a plugging direction to establish the plug-and-socket connection. The mixer (120) further comprises a guiding structure which is adapted to provide a guiding of the mixer along the plugging direction for establishing at least one of the plug-and-socket connections. The invention may help facilitating a placement of the mixer to a dental material dispensing device.
