The enamel thickness of upper central incisor in different facial contour types was measured as a guideline of enamel reduction for porcelain laminate veneer technique. The enamel thickness was 0.42±0.07mm at the cervical portion, 0.75±0.10mm at the middle portion and 0.83±0.01mm at the incisal portion. No significant differences in thickness were found among the different facial contour types. The results indicate that the enamel reduction should be at most 0.3mm around the cervical portion up to the crest of curvature in preparation for this technique although 0.5mm reduction might be allowed in other portions. The enamel thicknesses of mesial and distal portions showed good correlation with that of facial middle portion. Therefore, it is possible to estimate the reducible facial enamel thickness from the mesial or distal thickness through the radiographic examination.
