Technician’s Tip: Prep Check Tool

If your case doesn’t have enough occlusal clearance, you’ll typically get a phone call from our Quality Control department. You’ll also likely get a card with a small tool called PrepCheck™, which will help make sure you have enough space for future restorations.

At D&S Dental Laboratory, we prefer at least 1 mm occlusal clearance on all restorations except Lava and PFMs, where we prefer at least 1.5 mm occlusal clearance.

PrepCheck is a small tab that comes in three sizes (1, 1.5 and 2 mm). It can be inserted between the preparation and opposing dentition. If the tab doesn’t slide out with little resistance, you insert the coated side and have the patient tap or grind down on it. The special coating marks the teeth, showing you the areas that need to be reduced. It costs just $114 for a box of 50.
