CA 20:1 L Micro-Series

Thanks to the exceptionally ergonomic design of the Bien-Air 20:1 L Micro-Series implantology contra-angle, the word ‘comfort’ takes on a whole new meaning.

This contra-angle has an irrigation system which is internal to the instrument – a world first. So your grip is not impeded by the irrigation line. The jet of physiological liquid is projected onto the drill shaft itself, providing perfect cooling, particularly when using implant guides for insertions.

In addition, its shafts and gears are machined in stainless steel with high resistance to corrosion.

The Micro-Series 20:1 L contra-angle handpiece abounds with qualities: its small head, exceptional DuaLook lighting… and it is also the shortest and lightest contra-angle on the market. The benchmark in implantology instruments.


The Bien-Air Micro-Series brings together the Bien-Air series of compact contra-angles and handpieces and its micromotors with LED light. Lighter and more compact, the Micro-Series combinations offer exceptional grip and balance.


In addition to being robust enough to withstand all conditions, the dualstrand optical glass conductor gives an enveloping, non-dazzling light, clearly showing depth. DUALOOK: the best lighting on the market.


The most precise chuck locking and rotation drive technology in the world. Discover perfectly balanced instruments, with none of the drawbacks of imbalance or vibration. The best of Swiss technology.
