Perfect Preparation Every Time with Prep Check

For a successful restoration case, preparing a tooth is as important as fabricating an esthetic crown. Take the guesswork out of prep with PrepCheck®, a prep-marking system that allows for ideal thickness and promotes adequate reduction to minimize chairside adjustment and guarantee the strength of the restoration. Using PrepCheck is simple.

  • 1) Insert the dark half of PrepCheck between the prepped tooth and opposing dentition. If you’re able to remove it with very little resistance, the tooth is prepared correctly, and is ready for seating.
  • 2) Insert the light half of PrepCheck and have the patient bite down. The powdered marking medium will appear at points where contact is too tight.
  • 3) Reduce the areas marked on the prepped tooth. Repeat Step 2 until PrepCheck no longer marks areas for adjustment.
