Bien Air CA 20:1 L Contra Angle

Bien Air CA 20:1 L 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.

Longer service life The Most Durable Implantology Handpiece on the Market

The drive system of the CA 20:1 L contra-angle has been optimized to withstand more than 1600 uses @70 Ncm. This substantially increases the instrument’s service life.
