We don't sell equipment ourselves: we request quotes from several suppliers and aim to get you the best price.

DentalAirPolisher.com is independent in its editorial content. We may receive compensation from suppliers when a quote request leads to a sale; this never changes what we write.

How it is used

The Prophylaxis Master runs EMS's 8-step Guided Biofilm Therapy workflow: assessment, disclosing, motivation, supragingival air polishing (AIRFLOW), subgingival air polishing (PERIOFLOW, which EMS documents for 4–9 mm periodontal and peri-implant pockets), ultrasonic removal of remaining calculus (PIEZON), check and recall. Erythritol PLUS Powder is the standard powder in the air-polishing steps; sodium bicarbonate is reserved for heavy supragingival stain.

Studies that used this device

• Mensi et al., 2021 and 2022 (Clinical Oral Investigations). One randomized trial in the initial treatment of stage III–IV periodontitis, reported in two parts. Adding subgingival erythritol air polishing with this device to ultrasonic debridement gave no significant clinical advantage (closed pockets 47.9% vs 44.7% at 3 months). The second part reported a shift towards a healthier subgingival microbiome. The trial was funded by EMS.
• Mensi et al., 2024 (European Journal of Dentistry). Split-mouth randomized trial, 31 patients with stage III–IV periodontitis. GBT performed with this device achieved pocket closure comparable to scaling and root planing (77.9% vs 80.1% at 6 weeks; 84.1% vs 84.4% at 3 months; no significant difference). Several authors reported fees or support from EMS.
• Graetz et al., 2024 (BMC Oral Health). Split-mouth randomized trial, 60 patients, treatment by supervised dental students. GBT with this device gave results comparable to conventional instrumentation, with a significantly shorter treatment time (30.3 vs 34.6 minutes).

Taken together, these studies show comparable, not superior, clinical outcomes, with possible advantages in time and comfort.

Prophylaxis Master vs GBT Machine

Both are EMS combined tabletop systems with the same architecture (AIRFLOW, PERIOFLOW, PIEZON), the same powders and the same 8-step protocol. The GBT Machine adds automatic handpiece recognition, an automated GBT mode and the EMS Partner 2.0 connected dashboard. If a distributor quotes the Prophylaxis Master, ask whether the GBT Machine is also available in your market, and confirm long-term parts and service support.

Price: what changes the final quote

EMS does not publish a list price: the Prophylaxis Master is sold through national distributors, so the price is on request. These are the factors that move the quote.

• Country and distributor — EMS sells through national distributors, and terms differ between them.
• Configuration — handpieces, accessories, cart or mounting options.
• Training — whether EMS GBT training and certification are bundled or charged separately.
• Service — warranty length, maintenance contract and loan units during repairs.
• Financing — leasing or instalment terms change the monthly cost.
• Timing — EMS presents the GBT Machine as the successor, so ask whether the distributor still supplies the Prophylaxis Master and for how long it guarantees parts.

Running costs to budget

Beyond the purchase price, plan for powders (erythritol PLUS Powder for most appointments, sodium bicarbonate for heavy stain), wear parts and nozzles, and regular maintenance. Consumption depends on patient volume, case mix and technique, so ask the distributor for current consumable prices and a maintenance schedule rather than relying on generic figures.

Questions to ask the distributor

1. Which unit do you currently sell in my country — the Prophylaxis Master, the GBT Machine, or both?
2. What exactly is included: handpieces, starter powders, installation, training?
3. What are the warranty terms, and how long will parts and service be supported for the Prophylaxis Master?
4. What do the powders and wear parts cost, and what maintenance schedule do you recommend?
5. Can I see a chair-side demonstration before ordering?

FDA and Health Canada records (U.S. and Canada)

FDA 510(k) K190124 (decision date October 20, 2019, class II) covers the EMS AIRFLOW Prophylaxis Master and AIRFLOW One. Health Canada licence 102646 (AIRFLOW Prophylaxis Master, first licensed March 28, 2019). EMS AIRFLOW PLUS powder has its own 510(k), K171189 (class I). A 510(k) decision means "substantially equivalent" to a predicate; it is not FDA approval. A missing record means we could not verify it, not that the device cannot be sold. Confirm with the supplier that the record covers the exact model and kit. Records queried October 16, 2026. Source: openFDA 510(k) database and Health Canada MDALL.
