Patent number: 8251206Abstract: A device for storing and mixing a plurality of paste components which, when mixed, form a hardenable composition, includes a base plate and a cover. The base plate has an upper planar surface bearing two or more non-self-leveling pastes and adhered thereon in spaced apart areas and. The cover is adhered to the upper surface of the base plate around the pastes and defines a chamber for the pastes. No portion of the cover contacts the pastes.

Publication number: 20100167231Abstract: The invention includes a piston having a piston body (1) and front seal for sealing the gap between the side wall of the piston body and the wall of a chamber within which the piston and a material are disposed in a conventional manner. The front seal (5) has a leading edge (6) included angle (A) as defined below, and a trailing edge (7) included angle (B) that is smaller than the leading edge included angle. By the appropriate selection of these two angles, the force required to move the piston (and thus the material) is optimized, the force required to move the piston (and thus the material) is optimized, which results in a more useful dispenser than conventional syringe-type dispensers. These and other features of the present invention are described in greater detail below.Type: ApplicationFiled: November 21, 2007Publication date: July 1, 2010Inventors: John W. Dubbe, Gioacchino Raia, Hecht Reinhold, Manfred Ludsteck, Bruce R. Broyles, Henry C. Gydesen, Dirk Albrecht, Helmut Pauser

Patent number: 6554614Abstract: A dental brush has a plurality of bristles and is adapted to connect to a dental handpiece. As the brush is rotated, outer portions of the bristles shift and present an overall tapered configuration with a narrowed outer tip when the bristles come into contact with dental structure. The tapered configuration is particularly useful for finishing and polishing recesses in the patient's tooth structure such as interproximal areas, grooves located next to cusps of the teeth and recesses that may be present in dental restorations.Type: GrantFiled: May 3, 2001Date of Patent: April 29, 2003Assignee: 3M Innovative Properties CompanyInventors: John W.

Patent number: 6293796Abstract: A matrix clamp used in dental procedures to restore teeth to their natural shapes has a pair of gripping portions that are each connected to a cross-over bar. When the gripping portions are depressed by finger pressure, a pair of clamping tines connected to the cross-over bars spread apart from each other to enable the tines to be placed in contact with a sectional matrix band. When the gripping portions are released, a coil spring portion of the matrix clamp urges the tines toward each other so that the sectional matrix band is secured against the tooth and the clamp is retained in its selected position.Type: GrantFiled: October 27, 1999Date of Patent: September 25, 2001Assignee: 3M Innovative Properties CompanyInventors: Matthew C.

Patent number: 5988230Abstract: A device for consolidating compositions contained in partially filled dual chamber dispensing cartridges includes a body having a pair of passages, and first and second couplers for connecting the body to first and second dual chamber dispensing cartridges. Once the device is connected to two cartridges, an applicator is connected to one of the cartridges and is used to expel any remaining compositions in such cartridge to chambers of the other cartridge. The contents of several partially empty cartridges can be consolidated in this manner so that a subsequent dispensing operation need not be interrupted to replace cartridges.Type: GrantFiled: July 18, 1997Date of Patent: November 23, 1999Assignee: Minnesota Mining & Manufacturing Co.Inventors: Kevin L. Black, Frederick J. Turk, Bruce R. Broyles, Darin J. Meyertholen, John W. Dubbe, James D. Christoff
