The CA 20:1 contra-angle is a groundbreaking instrument featuring an internal irrigation system— a world first— ensuring your grip remains unobstructed by the irrigation line. This design directs the jet of physiological liquid onto the drill shaft, providing optimal cooling, especially when using implant guides for insertions. Boasting the lightest and most compact head on the market, the CA 20:1 is engineered for durability, with shafts and gears made from stainless steel resistant to saline solutions. Its drive system is optimized to endure over 1,600 uses at 70 Ncm, making it the most durable implantology handpiece available. Additionally, two dualook™ multi-strand optical glass conductors provide unobscured intraoral visibility from wider angles, ensuring precision in every procedure.
