Almost every porcelain veneer case we use a reduction guide. I generally have an incisal reduction guide and a facial reduction guide. Especially for minimal prep veneer cases, this is essential. The reduction guides are based off and made from a diagnostic wax up from our laboratory. We use Reliance Dental Lab and Williams Dental Lab (both located in California), routinely for our waxups. The reduction guides help to ensure that there will be adequate thickness of porcelain as your final restoration.
As you can see in the photos, we try to ensure a uniform thickness or equal space or reduction for each tooth for the future final restoration.
