It all began in Moutier (Switzerland), in a traditional village café in the heart of the famous "Watch Valley". David Mosimann, a business-minded precision mechanic, spent one of his coffee breaks chatting with a dentist, who lamented the limited performance of his rotary instruments. Keen to find ways to improve the practitioner's day-to-day work, David Mosimann set about producing his first handpieces. Slowly the project grew and, in 1959, the Bien-Air company was founded in a garage in the town of Bienne.

Right from its inception, Bien-Air set the bar high, affirming its expertise in micromechanics. The company's first turbines were considered the most reliable and durable on the market. In endless pursuit of innovations, the company took a decisive step in the 1970s when it launched its very first electric motor. Renowned for their exceptional precision and performance, Bien-Air instruments soon became popular with dentists.

Year after year, Bien-Air continued to revolutionise the medical world by producing rotary instruments and systems which are innovative, reliable and easy to use.
