DENTAL TOOL COMPRISING A VERSATILE TIP
First Claim
1. A head piece of a dental tool comprising a distal portion and a proximal portion, the proximal portion having a second interface which is configured to connect to a first interface of a hand piece of the dental tool, wherein the head piece comprises a communication means operable to provide a piece of information in relation to the head piece to a control system, the communication means comprising an electro-responsive portion configured to generate a signal indicative of a state or condition of the headpiece, wherein the electro-responsive portion responds with a first feedback signal to a first signal from a transmitter, said first feedback signal being received by the transmitter and processed by the controller, and wherein the feedback signal comprises identification information and/or measurement information related to any one or more of motion, vibration, acoustic noise, strain and stress from the headpiece.

Abstract
Dental tool comprising a hand piece and a head piece, the hand piece comprising a drive, a controller, a first interface and a transmitter which is connected to the controller, the head piece comprising a distal portion and a proximal portion with a second interface configured to connect the head piece to the hand piece via the first interface, the distal portion comprising a tip, which is configured to be driven by the drive, said drive being controlled by the controller. The headpiece comprises a layer whereby the layer comprises an electroresponsive material which is configured to react to a first signal from the transmitter.
