Biofilm arises even if these home care treatments are performed correctly and can lead to calculus formation and to serious diseases. Regular visits to a dentist are necessary for diagnosing the formation of biofilm or calculus and applying preventive techniques to neutralize their growth. A specific protocol developed by E.M.S. Electro Medical Systems S.A. from Switzerland, called Guided Biofilm Therapy (GBT®), ensuresthe most minimal invasive and comfortable treatment. This protocol includes disclosing and preventive steps, biofilm removal with Airflow® technology (air polishing technology), calculus removal with Piezon® PS (ultrasonic scaler) and at the end controls and recall steps. In order to reach the most efficient treatment with a non invasive and comfortable approach, we need to master the PS instrument motion. Laser Doppler vibrometry plays an important role and is used in the design and manufacturing of this high-end dental instrument.
