How is shade matching done for porcelain veneers?

At ACE DNTL, shade selection involves assessment under multiple light sources (daylight, fluorescent, incandescent), multiple shade systems including custom-mixed tabs, detailed shade mapping for each unit, and direct discussion between clinician and ceramist about the specific optical qualities to replicate.

What is metamerism in dentistry?

Metamerism is when a veneer appears to match the adjacent teeth under one light source but looks different under another. It occurs when the materials achieve a visual match through different spectral mechanisms rather than matching the actual optical properties of natural enamel.

Why do veneers sometimes look different colours in different lights?

Because the material's spectral response differs from that of natural enamel. This is a metamerism problem, preventable through careful material selection, multi-source shade verification, and the use of porcelain powders whose optical properties closely match natural tooth structure.

How does ACE DNTL Lab approach colour matching?

Colour is built into the veneer's internal structure through multiple layers and firings — not painted onto the surface. The ceramist works with direct knowledge of the patient's face and teeth, and every unit is verified under three light sources before release.
