PrepCheck is used to accurately reduce the height of teeth during crown preparations. It works like articulating paper and comes in three different thicknesses—1 millimetre for gold preparations or gold crowns, 1.5 millimetres for porcelain fused to metal, and 2 millimetres for all ceramic restorations.


What’s good about it

The patient bites on the PrepCheck and it leaves little marks where the tooth needs more reduction. It’s made of rubber so when the patient bites down, it should slide out easily if there has been adequate reduction. If the tab is difficult to remove, then it indicates that greater reduction is required. As the dentist is assured that enough has been taken off the tooth, it means there is less need for expensive remakes.

This product is particularly useful on second molars. It’s hard to see right at the back of the mouth and these teeth are generally quite short. When doing a crown preparation, you need 3 millimetres of the height left for retention and on second molars you’re really struggling to get those 3 millimetres. Once again PrepCheck helps the dentist by ensuring minimal but adequate tooth reduction has occurred.


What’s not so good

They come in boxes of 50 for $160 so the only disadvantage is that they’re $3.20 each.
