W&H WS-75 Implant Contra-Angle Handpiece (20:1)

The WS-75 is W&H’s premium 20:1 surgical implant contra-angle handpiece, designed for precise implant site preparation and implant insertion. Positioned above entry-level implant contra-angles, the WS-75 combines serviceable design, internal cooling, and multiple illumination options to support predictable clinical workflows in implantology.

Developed by W&H, the WS-75 features a dismantlable construction for thorough cleaning and long-term serviceability, a push-button chuck with hexagon chucking system, and the Kirschner/Meyer internal bur cooling system. This makes it well suited for busy implant practices that demand reliability, visibility, and maintainability.
