ＥＭＳ洁牙机以压电陶瓷的工作手柄作为换能器,在工作尖处产生频率为25～32ｋＨｚ的超声波振动,当工作尖与牙面接触时,既可除牙石,而且在工作尖末端还可产生空穴效应,在有水环间中形成氧化水,释放新生态纯净氧,从而有效地抑制牙周袋内深部的厌氧菌,更有效控制牙周病的发展。我 The EMS scaler uses a piezo-ceramic working handle as a transducer to generate ultrasonic vibrations at a working tip at a frequency of 25 to 32 kHz. When the tip is in contact with the tooth surface, it can remove the calculus and also at the tip of the tip. The cavitation effect can be generated. Oxidized water is formed in the water ring to release a new ecologically pure oxygen, thereby effectively inhibiting the anaerobic bacteria in the deep periodontal pocket and effectively controlling the development of periodontal disease.
