Aesthetic veneers are made without any metal. In classical crowns/veneers metal is used as the infrastructure material, opaque material is applied on it and it’s finished with a porcelain coating. In cases with high aesthetic expectations, we prefer natural-looking veneers with high translucency. In these veneers, we use zirconia or E-max, which is a glass ceramic material. So what are their differences? Zirconia is actually a white metal oxide and is often used as an infrastructure material in veneers. Tooth form and a natural appearance is obtained with the porcelain coating that gets applied on it. Thus, an aesthetic prosthesis that does not contain any metal, has natural light reflection, does not have any metal reflection in the gingiva, is obtained and is a highly biocompatible material.
On the other hand, the material we call E-max is completely ceramic and is one of the materials that has the best translucency. It looks very close to the natural tooth, but its durability is less than zirconia. We can use E-max as laminate or veneer.
Laminate is a treatment that we prefer when the tooth has only an aesthetic problem. When there are not many problems in the tooth position in general, but there is discoloration, small fillings or size problems. In order for us to choose this treatment, there should be no missing teeth and there should be problems that can be eliminated only by anterior surface abrasion. There should not be too much material loss in the tooth. In cases of full veneer, if there is too much discoloration of the tooth that needs to be masked, if there is too much force due to the lack of teeth, we prefer zirconia, which is more durable and less reflective of the underlying tooth color. On the other hand, we prefer E-max in smile design as a laminate or full veneer material when the force factors are low, and when we expect high compatibility with the natural tooth.
