The most luxury and popular crown is Emax. In dentistry, a veneer is a layer of material placed over a tooth. Veneers can improve the esthetics of a smile and protect the tooth surface from damage. There are two main types of materials used to make composite and dental porcelain. A composite veneer can be placed directly (built up in the mouth) or made indirectly by a dental technician in a dental laboratory and later bonded to the tooth, usually with resin cement.
It is usually used to treat adolescent patients who need a more permanent design once they are fully grown. The lifespan of a composite veneer is approximately 4 years. In contrast, an Emax veneer can only be made indirectly. A full veneer crown is described as “a restoration that covers all coronal tooth surfaces.” A laminate veneer, on the other hand, is a thin layer that covers only the surface of the tooth and is generally used for esthetic purposes. These generally have better performance and esthetics and are less prone to plaque.
Emax can never be mounted on an implant. So in order to use Emax you must have not missing teeth.
