Eliminator of dental calculus
Šobich, Adam ; Sekora, Jiří (referee) ; Rozman, Jiří (advisor)
Bachelor’s thesis is focused on system design of eliminator of dental calculus operating at a frequency of 27 kHz and reaching the intensity of ultrasound on the applicator tip to 5 W/cm2. The work analyzes problems of dental calculus, principle of ultrasonic waves and the physical phenomena occurring in the environment, which it passes. Another part of the work describes the creation of waves using ultrasonic transducer and the amplification of ultrasound in the waveguide. Practical part of work is presented by functional diagram, which describes the sequence and function of the main parts of the device. The Bachelor’s thesis presents individual steps for design of applicator and the circuit for eliminator of dental calculus, including calculations and diagrams. The resulting circuit is experimentally verified and supplemented with draft of the printed circuit board.
