The TwinPowerTurbine Ultra Series offers excellent cutting ability with smooth, chatter-free revolutions. A compact head design allows for exceptional posterior access and offers improved views with a mirror or microscope. Although they are ‘mini’ handpieces, clinician reviews have noted this series is powerful enough for everyday tooth preparation. Ultra-E (mini) is slightly taller than UltraM and more powerful at 20 watts, but still offers a compact head that improves the clinician’s view when using a mirror or microscope.
