EMS Electro Medical Systems.

EMS's about page says the company was founded in the Vallee de Joux in 1980 as a precision medical-device maker. It dates the invention of PIEZON to 1981 and AIRFLOW to 1982. AIRFLOW is described there as air, water, and powder for stain and biofilm. Later milestones on that page include the PIEZON PS instrument in 1998, subgingival AIRFLOW with glycine PERIO powder in 2003, the Swiss Dental Academy in 2006, and Guided Biofilm Therapy in 2016 as an eight-step protocol. The page says EMS employs over 900 people and that original products are Swiss-made.

A Dental Tribune company profile prints the address E.M.S. Electro Medical Systems S.A., Chemin de la Vuarpilliere 31, 1260 Nyon, Switzerland, telephone +41 22 994 47 00. It says Bernd Buhner and Pierre Mabille founded the company in 1981, which is one year later than the 1980 line on the current about timeline. Use 1980 for the about-page founding line and 1981 for PIEZON and for the founders' date in that profile. The Tribune profile's older text also cited more than 500 and, in another paragraph, more than 700 employees. The current about page's figure is over 900.

A 2026 Dental Tribune note from Nyon says the company was marking 45 years of PIEZON, 20 years of the Swiss Dental Academy, and 10 years of Guided Biofilm Therapy. It says PERIO powder in 2003 was glycine-based, AIRFLOW PLUS powder in 2013 was erythritol-based, and the AIRFLOW Prophylaxis Master was developed at the EMS research center. It also names the AIRFLOW MAX handpiece and a GBT Machine launched in 2025. Those product years are EMS's.

PIEZON is an ultrasonic scaler technology. AIRFLOW is air polishing. GBT is a protocol that uses both, plus assessment and education steps. Buying a scaler does not include the powder or the protocol training. The Swiss Dental Academy is the training body dated to 2006, and the about page says it has trained more than 200,000 clinicians. That attendance figure is the company's.

EMS suits a prophylaxis-focused practice that wants a Swiss ultrasonic scaler and air polisher and is willing to follow the powder and tip instructions. Ultrasonic scalers are compared on the ultrasonic scaler guide.

Air polishing is part of the same visit but a different handpiece. Do not treat AIRFLOW powder as a scaler insert.

PIEZON removes calculus with an ultrasonic tip. AIRFLOW uses air, water, and powder on biofilm and stain. GBT sequences those steps with assessment. An office can own the devices and still not be following the eight-step protocol.

Employee counts on older Tribune pages are lower than the current about page. Quote the about page's 900-plus figure as the later company statement, and do not treat it as a clinical claim.

The Tribune profile prints Chemin de la Vuarpilliere 31, 1260 Nyon, and +41 22 994 47 00. Confirm that service desk before you ship a handpiece.

Powders, tips, and the device are separate orders. PERIO and PLUS are not the same chemistry. Read the label before you aim a nozzle subgingivally.
