Abstract

An ultrasound dental treatment appliance having a surgical handpiece ( 220 ) fitted with a transducer connected to an ultrasound generator ( 230 ), the handpiece being designed to receive ultrasound tips ( 210 ) that are mechanically coupled to the transducer and that operate in different ultrasound wave power and amplitude ranges. The dental treatment appliance includes elements ( 224, 225 ), e.g. optical elements, for automatically detecting the utilization power and amplitude range of the tip ( 210 ) mounted on the handpiece, and a processor for automatically setting the ultrasound generator to the detected power and amplitude range.

Claims (23)

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.

2. The appliance recited in claim 1 , wherein the means for sending the impulse signal comprises a Dirac impulse generator.

3. A dental treatment appliance comprising:

an ultrasound generator;

a surgical handpiece comprising:

a transducer connected to the ultrasound generator and configured to produce an ultrasound vibration based on input from the ultrasound generator; and

an element mechanically coupled to the transducer, the element being configured to removably receive an ultrasound tip;

means for sending an impulse signal to the transducer when an ultrasound tip is received on the element;

a digital signal processor configured to receive and extract information from the transducer in the time; and

a processor configured to:

determine a type of ultrasound tip from the information extracted by the digital signal processor and interrogate a correspondence table to determine an ultrasound power and amplitude range corresponding to the type of ultrasound tip, the correspondence table including information on ultrasound power and amplitude ranges corresponding to each of a plurality of types of ultrasound tips; and

adjust the ultrasound generator to cause the transducer to produce an ultrasound vibration within the power and amplitude range determined from the correspondence table.

4. The dental treatment appliance recited in claim 3 , wherein the means for sending the impulse signal comprises a Dirac impulse generator.

5. The dental treatment appliance recited in claim 3 , further comprising an ultrasound tip removably secured to the element so as to be mechanically coupled to the transducer, the response signal corresponding to the type of ultrasound tip removably secured to the element.

6. The dental treatment appliance recited in claim 5 , wherein the type of ultrasound tip is one of: a scaling tip, a surfacing tip, and a cutting tip.

7. A dental treatment kit, comprising:

the dental treatment appliance as recited in claim 3 ; and

a plurality of ultrasound tips, each being removably securable to the element so as to be mechanically coupled to the transducer, each ultrasound tip corresponding to a different one of the types of ultrasound tips for which information is included in the correspondence table.

8. The dental treatment kit recited in claim 7 , wherein the plurality of ultrasound tips comprises: a scaling tip, a surfacing tip, and a cutting tip.
