Guided Biofilm Therapy - GBT


Guided Biofilm Therapy (GBT) is a scientifically proven, systematic, predictable solution for dental biofilm management in professional dental cleaning, using state of the art AIRFLOW®, PERIOFLOW® and PIEZON® technologies. 
Guided Biofilm Therapy consists of treatment protocols based on individual patient diagnosis and risk assessment in order to achieve optimal results. The treatment is given in the least invasive way, with the highest level of comfort, safety and efficiency

Before removal the biofilm is always disclosed with a dye solution. Then biofilm and young calculus are easily removed with AIRFLOW® and PERIOFLOW® – above and below the gum.  If needed this is followed by debridement with PIEZON® PS No Pain piezoceramic instruments.

Guided Biofilm Therapy is truly minimally invasive and reduces the need of hand and sonic/ ultra-sonic instrumentation. It is safe, effective and gentle to teeth and soft tissues, implants and restorations.

GBT is part of a comprehensive preventive concept – to preserve your patients’ oral health – and to make the patients feel good.



Superior cleaning - Highly effective at removing difficult stains from coffee, tea, wine and tobacco

Minimally invasive, gentler and more comfortable than a traditional cleaning

Dental cleanings using GBT are faster and therefore means spending less time in the dental chair



This contemporary approach begins with above and below gum biofilm removal using air-polishing technology with AIRFLOW® PLUS® Powder. This erythritol-based powder guarantees targeted, gentle, risk-orientated removal of the biofilm.
This is followed by the minimally invasive removal of mineralised build-up with PIEZON® NO PAIN. This approach has many additional benefits, including short treatment times and maximum comfort for both the technician and the patient. GBT is minimally invasive. Polishing paste and rubber cups are no longer necessary.
With GBT, we can finally carry out professional biofilm management effectively, gently, safely, quickly, comfortably and without pain.
