Every evolution of the Bora and Prestige series embodies Bien-Air’s user-focused approach to micro-precision engineering. Impressive bur concentricity, safe cooling of the treatment site, and near-perfect weight distribution are just three of a tall list of performance- and comfort-enhancing features for you to benefit from. With Prestige’s most compact head, those hard to reach areas in the back of the mouth are accessed with surprising ease. Exceed the high standards you’ve set for yourself with the proven competence and quality this progressive series stands for. This proven bur-locking and vibration-canceling system vouches for optimal stability and precision, no matter the rotational speed. Assembled with Bien-Air's Soft PushTM button, bur release is quick and easy. The ultra-precise nebulization system is composed of three separate air and water sprays providing comprehensive cooling to the bur and treatment site. Combined with LED light and two dualook™ multi-strand optical glass conductors, unobscured intraoral visibility is guaranteed from wider angles. Conveniently integrated into the head's push button, this patented anti-heating technology is designed to maintain the instrument's head at a safe temperature, thus significantly decreasing patient burn injuries. In combination with an anti-retraction valve, this wear-resistant mechanism prevents oral fluids and other organisms from infiltrating the instrument's head, water lines, and treatment unit. This obviates the risk of patient cross-contamination and noticeably prolongs the ball bearings' lifespan. The wear-resistant Bien-Air ceramic ball bearings grant the handpiece extended service life and contribute to lower acoustic noise levels. Freedom of movement for optimum working comfort. Thanks to its light rotating Unifix quick-connect connection and an easy-to-use secure release, the Bien-Air turbine/hose combination will prove a pleasant work companion day in, day out.
