Patent number: 6986924Abstract: A foil sheet of semi-rigid laminated material provides a disposable adhesive pad which includes adhesive on portions of opposing top and bottom surfaces. On a portion of the top side an adhesive is covered by a peel-off label that preferably includes advertising. The remainder of the top surface is substantially a fictionless foil surface. The opposite bottom side is also provided with an adhesive on a portion of its surface. The foil is a medical metal foil that is insoluble in saliva, prophylactic paste, and water. The device is substantially planar, however two wings may be formed along foldlines which provide sidewalls that extend upwardly from the top surface and contain a dental material such as a cleaning paste, holding it on the foil portion of the pad.Type: GrantFiled: December 16, 2003Date of Patent: January 17, 2006Inventor: Theodore P.

Patent number: 6971879Abstract: A dispenser made of a pliable material having a slit therein for dispensing primarily low viscosity materials. A block made of pliable foam contains a low viscosity material within a slit. Dental instruments or dental material applicators having an applicating end are inserted into the slit of the block, coating the applicator end with the low viscosity material. The resilient nature of the block material also helps to keep the dental instrument clean by wiping the instrument against the interior sides of the pocket formed by the slit. The present invention is particularly well suited for dispensing a lubricating material, such as a resin, on dental instruments used in working, shaping, or contouring a relatively viscous composite restorative material on a patient's tooth.Type: GrantFiled: September 22, 2003Date of Patent: December 6, 2005Assignee: Centrix, Inc.Inventor: John J. Discko, Jr.

Patent number: 6860737Abstract: The invention relates to a tool for establishing correct interproximal contact between a tooth that has been bored out and the cavity filled with plastic filling, and an adjacent tooth with a contact surface directed towards the bored out tooth referred to, with plastic filling. The tool is provided with two outer pins and a central pin. The outer pins create stability for the tool, when a head of the tool, and from where the pins extend, is arranged in the bored out cavity. The central pin ensures, together with the outer pins and facing outs between the pins, that it is possible to establish the correct interproximal contact for the plastic filling against the contact surface of the adjacent tooth.Type: GrantFiled: February 25, 2002Date of Patent: March 1, 2005Inventor: Jens Ulsø

Patent number: 6769912Abstract: In a device for the automatic production of dental replacement parts, a blank 13 is fitted in a substantially plate-shaped carrier body 10 which is so dimensioned that the blank 13 does not exceed the carrier body 10 in any direction. The carrier body 10 serves not only for holding the blank 13 in the working machine but also for protecting it during its automatic handling in magazines or the like. The carrier body 10 is provided with a bar code 20 which relates to the material and dimensions of the blank 13 and may identify data according to which the blank 13 is to be worked The bar code 20 is adapted to be changed by the working machine so as to prevent the carrier body 10 from being reused with the same or a different blank 13.Type: GrantFiled: June 13, 2002Date of Patent: August 3, 2004Assignee: 3M ESPE AGInventors: Martin Beuschel, Erich Huber, Erich Sendelbach, Olaf Schäfer

Publication number: 20040091836Abstract: One embodiment is a dental appliance, and another embodiment is a method for using a dental appliance to position a veneer, for example a ceramic or porcelain laminate veneer, on the surface of a tooth. One embodiment of the dental appliance comprises a plurality of grippers, allowing a dentist to adjust the position and hold a veneer on the tooth during the bonding process. Another embodiment of the dental appliance comprises one gripper, allowing a dentist to adjust the position and hold a veneer on the tooth during the bonding process. One embodiment of the method includes repositioning of the veneer using a dental appliance, holding the veneer with the dental appliance while excess adhesive is removed and a light source probe is used to cure a localized area of a light-sensitive adhesive, again repositioning the veneer using the dental appliance, and holding the veneer with the dental appliance during curing of another localized area.Type: ApplicationFiled: August 28, 2003Publication date: May 13, 2004Inventor: Marc Lazare
