Twist® Plus is a unique disposable prophy angle that moves in a 120° reciprocating (back-and-forth) motion instead of a traditional spinning motion. This patented mechanism greatly diminishes frictional heat while reducing the spatter of prophy paste, saliva, blood and other potentially infectious materials. The innovative ergonomic design optimizes comfort as well as visibility during procedures.- Prophy Angle, Firm Cup White, Disposable, 100/bx Stock Item
