  • Patent number: 8814738
    Abstract: A device for dispensing a dental composition comprises a piston for extruding a component of the dental composition from a container. The device has a roller drive for displacing the first piston. The roller drive comprises cooperating first and second rollers, and each of the rollers have a roller surface with a radial rib profile. The rollers are arranged for rolling with their roller surfaces on one another. The invention may help providing for a relatively reliable and compact device.

  • Patent number: 8807394
    Abstract: A system comprises an automatic mixing and dispensing device for a dental substance, and a material container. The mixing and dispensing device comprises a reservoir for receiving the dental substance, and first and second pressure plates. The material container has first and second material chambers for containing components of a material. The first and second material chambers have first and second cross-sectional chamber areas. At least one of the first and second cross-sectional chamber areas is smaller than smallest surface area of the first and second pressure plates. The system helps facilitating preparation and handling of dental materials.
