Abstract
A device for dispensing a dental material comprises a compartment for the dental material, a piston for extruding the dental material from the compartment, and a spindle drive for moving the piston and the compartment relative to one another. The spindle drive comprises first and second threads which are operable for moving the piston. The first thread has a first pitch and the second thread has a different second pitch. In one embodiment, the invention may provide a relatively inexpensive and reliable dental dispensing device.
