Disclosed is a device for metering measured amounts of dental restorative resin. The device includes a cylinder and a hub arranged so that rotation of the cylinder on the hub moves the members axially a known amount to create an opening in the end surface of the cylinder. After the opening is filled with the resin, the members are rotated back, which causes the hub to push the material from the opening up to the level of the end surface of the cylinder.
