Detailed description
Drawing on Bien Air's long-standing technical expertise, this CA 20:1 contra-angle integrates DuaLook dual glass-conductor lighting and Accu-Spray with three separate air/water sprays to ensure consistent misting. The drive system features improved axes and gears mounted on preloaded ball bearings for enhanced rotational stability.

The model incorporates an internal irrigation channel — a world first — which eliminates external irrigation tubing during handling. The irrigation jet is delivered on the drill axis to optimise cooling, particularly for procedures using implant guides. The miniature head reduces interferences in the operative field and the stainless steel shafts and gears provide high resistance to saline solutions.

The cutter drive and clamping system, Accu-Chuck, is engineered to minimise vibration and ensure stable, precise clamping at all speeds. The associated Soft Push mechanism enables rapid, tool-free cutter release and clamping with a single push button, facilitating quick and ergonomic instrument changes.
