Bien Air Optima and Optima MX are excellent electric handpiece systems capable of most anything you can imagine for clinical use. Some surgical applications can be arranged as well as Bien Air offers some very good speed reducing contra angles with the ability to adjust air/water spray.
Bien Air Optima – 200,000 RPM?
Bien Air Optima is one of the first to support speed increasing contra angles capable of 200,000 rpm. Achieving this speed is as easy as placing the e-type 1:5 contra angle onto the 40,000 rpm motor. Full air/water spray at this point makes the handpiece a high speed capable of gross material reduction and quick cavity preparation.
