Bien-Air.

Bien-Air Dental's about page says David Mosimann, a precision mechanic, started making handpieces after a conversation with a dentist in Moutier and founded the company in a garage in Bienne in 1959. The page says the first turbines were built around micromechanics, that the first electric motor came in the 1970s, and that in 2001 the firm split dentistry and microsurgery into Bien-Air Dental and Bien-Air Surgery. Vincent Mosimann, David's son, took over in 1994. Headquarters remain in Bienne, with production and assembly in Noirmont, eight subsidiaries, and more than 400 employees worldwide, according to that page.

The US about page repeats the 1959 Bienne founding and adds a timeline: an RA turbine in 1959 described as a ball-bearing turbine, Gyro air-bearing turbines in 1965, a reversible electric micromotor in 1970, Unifix couplings in 1978, Bora turbines in 1991, the Chiropro 980 physiodispenser in 1998, brushless MX motors in 2005, Micro-Series contra-angles in 2011, and Tornado turbines from 2015. Those firsts and power claims on the US timeline are Bien-Air's wording. A 30-watt Tornado figure, if you see it, belongs to that timeline and should be checked on the current data sheet.

A 2007 regional obituary says David Mosimann died on 1 December of that year at age 81, that he founded Bien-Air in Bienne in 1959, and that production sat in the Franches-Montagnes, with staff at Saignelegier for dental and at Le Noirmont for surgery. The about page's later Noirmont production line is the company's current description. The obituary's headcount, more than 350, is older than the about page's more than 400.

Air-driven turbines, electric motors, and implant physiodispensers are different devices. Chiropro and iChiropro are the implant and surgery names on the US timeline. They are not a high-speed turbine. Contra-angle gear ratios have to match the motor. The US timeline also lists LED lighting in 2009, Optima integration for electric motors on air-powered chairs in 2007, and a Tornado X turbine in 2019 described as marking 60 years. A 2007 Dental Products Report interview with the US general manager said electric handpieces reached the US market from Bien-Air in 1995 and that manufacturing stayed in the Jura. That interview's claim about being the largest electric-motor maker is the speaker's wording. The about page's figure of more than 400 people and eight subsidiaries is the later company description to use for scale, and it still does not choose the coupling on your delivery unit.

Bien-Air suits a practice buying Swiss air or electric handpieces, or an implant motor console, from the Bienne company. Handpieces are compared on the air and electric handpiece guide.

Implant motors are on the implant motor guide. A Chiropro is that category. A Tornado turbine is not.

The 2001 split put dental rotary instruments and microsurgery instruments in different divisions. An ENT set is not a dental contra-angle.

Family ownership is the about page's description, with Vincent Mosimann taking over in 1994. It does not list a corporate parent. The invoice should still show Bien-Air Dental for a dental handpiece.

The about page places headquarters in Bienne and production in Noirmont, with eight subsidiaries. Ask the US subsidiary which warehouse ships couplings and which factory services a turbine.

Power numbers on older timelines need the current sheet. A 1970 motor speed is not the speed of an MX brushless motor.
