Today, the use of piezoelectric instruments in dentistry is becoming more widespread and their effectiveness is demonstrated by numerous clinical studies.
The piezo effect of Satelec® piezoelectric handpieces can be described as either indirect or direct. The so-called piezoelectric bodies - ceramic rings - are deformed (by expansion or contraction) when polarized through application of an electric field.
Electric current generates a deformation of the piezo ceramic rings. The amplifier and tip, coupled together, increase the vibrational movements emitted by the piezo ceramic rings. The tip thus vibrates along a longitudinal axis.
