BIEN-AIR’S CONTRA-ANGLES & STRAIGHT HANDPIECES.
Unfailing Precision.

Over the long term. Even the best dentist is nothing without a good instrument. Bien-Air contra-angles and handpieces offer you the best of Swiss microtechnology. Designed and manufactured in the heart of Watch Valley, each instrument is a masterpiece of metal-working, where skills combine to create a robust, ultra-precise and quiet device.

From endodontics and surgery to implantology and restoration, Bien-Air has the instrument you need.

Contra-Angle 20:1 L

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.
The CA 20:1 has a miniature head and is the lightest on the market.In addition, its shafts and gears are machined in stainless steel with high resistance to saline solutions.

Bien-Air’s new generation Micro-Series models ally innovation with compact design, resulting in improved power and maneuverability. Up to 30% shorter and 23% lighter than traditional models, they have an easy grasp that allows for optimal work comfort with less strain on the hand, arm, and shoulder.
