Dürr Dental's first air polishing handpiece for dental prophylaxis is the new benchmark in compactness and as a system. The design realizes ideal ergonomics and perfect weight balance. The interchangeable powder container is fully integrated. The innovative bayonet coupling enables change of containers at any time without danger of dispersion. Thus, the reasoned system combines capability of stationary devices with flexibility of a handheld one (which did not have that capability so far). The system enables an automatic internal and external disinfecting and sterilizing cycle. So the latest standard of Robert-Koch-Institute has been materialized.
