The ContacEZ IPR Strip System is an interproximal enamel reduction system that makes IPR safer and more accurate without cutting excessive enamel. Designed for use with Invisalign, Clear Correct, and other ortho treatments, these strips curve and flex along the natural contours of the teeth, preventing soft tissue irritation and maximizing patient comfort.  Every ContacEZ is a strong, flexible strip permanently housed in an autoclavable FDA approved plastic casing.
