Patent ID: 8376753

Claim:
A device for learning and training in dental treatment techniques, wherein forces can be exerted on a tooth secured in a model of a jaw in order to examine or to work on the tooth, the device comprising: a tool for a user to perform a dental treatment technique on the tooth, the tool exerting forces on the tooth in response to how the user uses the tool to perform the dental treatment technique; means for converting exerted forces into electrical measuring signals, said converting means comprising a measuring device, the measuring device consisting of a single sensor fixed underneath the model of the jaw, constructed as a six-component force-moment sensor; a data processor coupled to said sensor so that the measuring signals are fed to the data processor, the data processor including means for imaging the measuring signals as forces according to their magnitude and direction, the data processor further comprising a data memory, in which a plurality of reference-force-time curves of different dental treatment steps can be stored as a table of values that can be called up, means for controlling the data processor such that a selected reference-force-time curve and the actual force-time curve of the simulated dental treatment can be represented on an optical display; and an optical navigation system for the determination of the position of the tool, said navigation system comprising at least one camera.
