Patent number: 11087870Abstract: A system of tracing a dental prosthesis, the prosthesis including an electrical power source coupled with a radio-communications signals transmitter capable of assuming a weakly active state in which it periodically sends out signals at a first transmission frequency, and a highly active state in which it periodically sends out signals at a second, higher transmission frequency, and a presence sensor for sensing presence of the prosthesis in a mouth of a user, capable of delivering information on absence of the prosthesis in the mouth. The transmitter is configured to pass from the weakly active state to the highly active state when the sensor delivers information on absence of the prosthesis in the mouth. The system also includes a base forming a support of the dental prosthesis when not worn by a user, and the transmitter assumes the weakly active state on detecting the prosthesis in proximity to the base.Type: GrantFiled: July 7, 2017Date of Patent: August 10, 2021Assignees: UNIVERSITE D'ANGERS, CENTRE HOSPITALIER UNIVERSITAIRE D'ANGERSInventors: Annick Barthelaix, Jocelyn Rio, Antoine Spiesser
