The classical method, which has been used for many years in dental restorations, is to grind around the teeth a little, to prepare a metal infrastructure on them, and then to make a tooth out of this infrastructure from porcelain.

Because the restorations contain metal and porcelain, it was thicker than natural tooth enamel, and because the metal structure underneath was reflected on the porcelain, it was dull and dark in color. Since the emergence of zirconium, these disadvantages are no longer a problem.

Today, dental veneers, which are similar to natural tooth enamel and formed in layers, are used. The most commonly used of these is zirconium.

Zirconium veneers are light-permeable and can reflect the color of the underlying natural tooth. For this reason, it looks much more natural and is often indistinguishable from a real tooth. The absence of the metal layer allows much less cutting of the tooth and less sensitivity. Since zirconium is made in layers, the teeth are not a single color, they can be produced in a polychromatic (multi-toned) way to imitate natural teeth.
