Patent number: 9452027Abstract: A vibrating applicator is provided for applying a dental composite material onto a tooth. The applicator has an elongated body and a tip that is coupled to the elongated body to apply the dental composite material onto the tooth. The applicator further has a vibrating apparatus for vibrating the tip and a sensor for sensing a condition of the dental composite material. A controller is operatively coupled to the vibrating apparatus and to the sensor and is configured to automatically vary an output frequency of the vibrating apparatus in response to the condition sensed by the sensor.Type: GrantFiled: December 10, 2009Date of Patent: September 27, 2016Assignee: KerrHawe SAInventors: Beat Kilcher, Marco Da Rold

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. Schmidlin, Beat Kilcher, Marco Da Rold

Publication number: 20120202166Abstract: A vibrating dental instrument is provided that may be used with different styles of tips for performing different dental procedures. The dental instrument has an elongated body and a tip that is releasably coupled to the elongated body. The dental instrument further has a vibrating apparatus for vibrating the tip and a sensor for sensing a condition of a dental composite material when the tip is used to apply the dental composite material onto a tooth. A controller is operatively coupled to the vibrating apparatus and to the sensor and is configured to automatically vary an output frequency of the vibrating apparatus in response to the condition sensed by the sensor.Type: ApplicationFiled: April 20, 2012Publication date: August 9, 2012Applicant: KERRHAWE SAInventors: Beat Kilcher, Angelo Putignano, Marco Da Rold, Hinko Kovacevic

Publication number: 20110189629Abstract: The dental matrix band includes an elongated body having first and second opposing ends adapted to wrap around a tooth to be restored, and having first and second opposing longitudinal edges extending between the first and second opposing ends. The dental matrix band further includes a first line of weakness in the elongated body where the elongated body is separable along the first line of weakness. The dental matrix includes a fixture adjacent the first line of weakness. The dental matrix band may further include a second line of weakness. The dental matrix band may include an annealed section.Type: ApplicationFiled: February 1, 2011Publication date: August 4, 2011Applicant: KERRHAWE SAInventors: Beat Kilcher, Marco Da Rold

Publication number: 20080090205Abstract: 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: ApplicationFiled: August 20, 2007Publication date: April 17, 2008Applicant: KERRHAWE S.A.Inventors: Beat Kilcher, Marco Da Rold, Valerie Boscherini-Da Silva, Luca Pedrinis

Patent number: 7195395Abstract: A dental sensor clamp has a clamp body with a connector on one end for connecting the sensor clamp to a bite plate. A clamp body opposite end has a fixed stop locatable adjacent an apical area of a tooth. A clamping slide is mounted within a thickness of the clamp body, and the clamping slide supports a member providing a resilient clamping force upon the member being moved against the sensor and the fixed stop. The dental sensor clamp reliably secures an imaging sensor adjacent the apical area of the tooth.Type: GrantFiled: February 28, 2005Date of Patent: March 27, 2007Assignee: KerrHawe SAInventors: Antony Quarry, Beat Kilcher, Marco Da Rold, Rolf M. Klauser
