Principles of ultrasonic cleaning tooth

1. Piezoelectric ceramic scaler. Using a piezoelectric ultrasonic generator, its working principle is: the crystal of the transducer vibrates with the change of battery strength and frequency, thereby driving the linear movement of the cleaning tip.

2. Magnetic stretch

The working principle of the retractable scaler is: the length of the magnetic transducer in the body of the working head expands and contracts with the change of the direction of the magnetic field, which drives the movement of the working tip and converts electrical energy into mechanical energy. Magnetic transducers are usually made of thin slices of magnetic materials such as tweezers. The working head of the magnetostrictive tooth cleaning equipment runs in a spiral manner, and relies on the vibration of the side of the handpiece to effectively clean up dental calculus and dental plaque, so it does not cause damage to the tooth enamel. The subgingival curettage can generally be completed within 2-3 hours without anesthetics, and the maximum depth is 14mm below the gum. It can also be used for supragingival cleansing and root canal washing.

3. Sonic cleaner. In recent years, sonic cleaners have been widely used. It transfers the energy of the compressed air to the working tip through the transducer, so that the working tip produces an elliptical motion of 2500-7000 Hz, which is converted into mechanical energy. 4. Ultrasonic scaler. The high-frequency oscillation circuit generates a high-frequency oscillation signal and acts on the ultrasonic transducer. The inverse piezoelectric effect (or magnetostrictive effect) is used to generate ultrasonic vibration. The working tip is excited to generate resonance. Removal of plaque, stones or bacteria on the tooth surface.
