What is the facial minimal standard reduction required for porcelain laminate veneers?

  1. 0.3mm

  2. 0.5mm

  3. 0.7mm

  4. 1.0mm

The correct answer is: 0.3mm

Facial minimal standard reduction is an important aspect to consider when creating porcelain laminate veneers, as it affects the overall results and longevity of the veneers. A reduction of 0.3mm is generally accepted as the minimum requirement for successful veneers, as it provides enough space for the veneers to fit comfortably and bond to the tooth surface. Options B, C, and D all exceed the recommended minimal standard, which can lead to unnecessary tooth structure removal and potentially compromise the strength and aesthetics of the veneers. Therefore, option A is the best choice for achieving the desired results while preserving the natural tooth structure.
