"GBT machine" is a search term clinics often use when looking for the equipment used in Guided Biofilm Therapy workflows. We explain what GBT actually is, what equipment is involved and how to request information from suppliers.
"GBT machine" is not a precise technical term. It is the search term that clinicians and practice managers tend to use when they want to know which equipment is used in Guided Biofilm Therapy. The reference equipment associated with GBT is the EMS Airflow Prophylaxis Master combined with EMS-validated powders and accessories. However, GBT is fundamentally a protocol, not a single device.
Guided Biofilm Therapy (GBT) is a structured prophylaxis protocol developed and promoted by EMS and the Swiss Dental Academy. The core idea is to make biofilm management the foundation of every hygiene appointment — visualizing biofilm, removing it efficiently with low-abrasion air polishing, and only then performing scaling on residual hard deposits.
A typical GBT session follows a defined sequence: assessment, disclosing, motivation/instruction, supragingival air polishing (Airflow), subgingival air polishing where indicated (Perioflow), ultrasonic scaling for any residual calculus (Piezon), and a final quality check.
Both, depending on how you look at it:
Air polishing as a clinical technique exists outside GBT. Many clinics use air polishing without formally adopting Guided Biofilm Therapy. Other manufacturers offer their own air polishing systems, with different powders and protocols.
Equipment pricing for a GBT-ready setup depends on the configuration, country and distributor. The reference unit (EMS Airflow Prophylaxis Master) sits at the premium end of the air polishing market. We publish dedicated guidance on EMS Airflow Prophylaxis Master pricing.
Most distributors will arrange a chair-side demo and structured GBT training. Confirm whether GBT certification is bundled in the offer or priced separately.
If you are interested in the clinical concept of structured biofilm management — but not necessarily in the GBT protocol or in EMS equipment — there are alternative air polishing systems and workflows to consider:
In practice, when clinics search "GBT machine" they are usually looking for the equipment used in GBT workflows — most commonly the EMS Airflow Prophylaxis Master. But GBT is a protocol, not a single machine.
You can perform structured air polishing with many systems, but the formal GBT protocol and certification are tied to the EMS / Swiss Dental Academy ecosystem. Other manufacturers promote their own protocols.
No. The protocol is positioned as a routine prophylaxis approach for all patients — including healthy, periodontal, peri-implant, orthodontic and pediatric cases.
