Publication number: 20210154412Abstract: A new type of syringe for delivering composite material for direct application of the material in the mouth of a patient. The new type of syringe includes a threaded screw for driving a piston through the syringe in order to extrude the material from the end of the syringe. The extrusion force is thus generated in the syringe, thereby allowing for a simpler, less costly motorised driving system using a torque driving movement. The syringe also includes a localised heating arrangement at the extrusion end.Type: ApplicationFiled: July 2, 2019Publication date: May 27, 2021Inventors: Didier DIETSCHI, Beat KILCHER

Patent number: 8992224Abstract: The method of curing a dental composite includes forming a composite filling in a cavity of a tooth surface by filling the cavity with an uncured composite and determining the geometry of the composite filling, including locations of interfaces between the composite filling and the tooth surface. The method further includes calculating a predetermined polymerization pattern for minimizing shrinkage stress at the interfaces, based on the geometry of the composite filling, and scanning a focused laser beam across the composite filling in accordance with the predetermined polymerization pattern to selectively and progressively cure the composite filling.Type: GrantFiled: March 15, 2013Date of Patent: March 31, 2015Assignee: KerrHawe SAInventors: Beat Kilcher, Vahik Krikorian

Publication number: 20140106297Abstract: A dental bur and method for removing a soft deposit from a tooth or an implant, the bur having a shank adapted to be connected to a rotary device. A head extends from the shank. The head has a material hardness adapted to remove soft deposits attached to the tooth but deflect against the tooth. Furthermore, the head is sized for insertion into a periodontal pocket adjacent to the tooth without surgery. Thus, the dental bur may be rotated against the tooth for removing the soft deposits but deflect and/or wear against the tooth for preventing damage to the tooth.Type: ApplicationFiled: March 15, 2013Publication date: April 17, 2014Applicants: University of Zurich, KerrHawe SAInventors: Patrick R.

Patent number: 8518380Abstract: A prophylactic (prophy) paste composition comprising about 40 percent by weight to about 55 percent by weight expanded perlite comprising perlite granules in the range of about 20 ?m to about 70 ?m and floaters. The prophy paste composition further comprises no more than 5 percent by weight of a surfactant, and greater than about 10 percent by weight water. In some embodiments, the inventive paste also contains a humectant and optionally, may contain coloring agents, preservative agents, alcohol, flavoring agents, viscosity increasing agents, and sodium fluoride. The present invention also provides methods for controlling the floater content of the expanded perlite used in the inventive paste and methods of packaging the expanded perlite paste composition in a tube. The present invention also provides a prophy paste product comprising the inventive prophy paste contained within a squeezable tube.Type: GrantFiled: December 5, 2007Date of Patent: August 27, 2013Assignee: KerrHawe SAInventors: Patrizia Balmelli, Beat Kilcher

Patent number: 7648361Abstract: A dental dam clamp comprises first and second spaced, opposing jaws and respective first and second tooth engaging portions on the jaws. The first and second tooth engaging portions are positioned in confronting relation to one another and are biased toward one another by a resilient member when the jaws are moved outwardly from a free state defining a first position of the jaws. In one embodiment, first ends of the tooth engaging portions are spaced closer together than the second ends of the tooth engaging portions when the jaws are in the first position. The spacing between the first ends of the tooth engaging portions may be substantially the same as the spacing between the second ends of the tooth engaging portions when the jaws are moved outwardly to a second position. In another embodiment, the tooth engaging portions include friction-increasing surfaces to help secure the clamp to a tooth.Type: GrantFiled: August 20, 2007Date of Patent: January 19, 2010Assignee: KerrHawe SAInventors: Beat Kilcher, Marco DaRold, Valerie Boscherini-DaSilva, Luca Pedrinis

Patent number: 7332150Abstract: A material is proposed as an essential abrasive component for cleaning agents in cleaning products for delicate surfaces which is essentially composed of platelets. These platelets are preferably shaped without sharp points, i.e. their circumference is similar to a polygon whose corners do not show angles that are in the majority smaller than 30° and greater than 330°. Glass flakes are for example such a material. The abrasive component of the invention may for example be used for the manufacture of toothpastes and prophylaxis pastes that are efficient but nevertheless not harmful to teeth.Type: GrantFiled: December 8, 2000Date of Patent: February 19, 2008Assignee: KerrHawe S.A.Inventors: Gert Ulrich Silber, Beat Kilcher, Beat A.
