Abstract:
1. An ultrasound dental treatment appliance configured to receive ultrasound tips, the ultrasound dental treatment appliance comprising: a surgical handpiece fitted with a transducer connected to an ultrasound generator, said handpiece being configured to removably receive, one at a time, an ultrasound scaling tip, an ultrasound surfacing tip, and an ultrasound cutting tip, wherein the handpiece is configured such that the ultrasound tips are mechanically coupled to the transducer when received by the handpiece and operate in distinct different ultrasound power and amplitude ranges corresponding to the respective ultrasound tip type, information on the respective ultrasound tip types and corresponding ultrasound power and amplitude ranges being stored in a correspondence table; means for sending an impulse signal to the transducer; a digital signal processor that receives and extracts information from the transducer in the time domain; and a processor that uses the information extracted by the digital signal processor to determine the type of tip mounted on the handpiece and interrogates the correspondence table and adjusts the ultrasound generator to a power and amplitude range matching the determined type of tip, said range extending between a lower limit and an upper limit defining respective minimum and maximum power and amplitude values of the determined tip.
