The state-of-the-art VETROSON® Millennium 25/30 ULTRASONIC SCALER makes other scalers look obsolete. It accepts standard 25K inserts as well as the new 30K inserts. It also features a new autotuning concept. It zeros in on the natural resonance of an insert and produces a spray pattern that is more consistent for a wider spectrum of inserts. Its power setting can be adjusted to low during perio work and high when scaling above the gums. Both settings have outstanding cavitation and spraying patterns. The existing scalers that have one power setting can't be used when working below the gums. VETROSON® Millennium 25/30 Ultrasonic Scaler features a power booster system that increases power automatically to the point between perio setting and maximum power. By pushing the button once more, it will go back to normal subgingival debridement.
