All - ceramic cases

The inner surface of all-ceramic crowns is also made of a ceramic material whose strength is now almost equal to that of metal. The absence of metal inside the case is what gives the absolute aesthetic effect as well as the permeability of light as in natural teeth.
By choosing all-ceramic cases, we are sure of the aesthetics of the result as their transparency is similar to that of natural teeth. When we bring metal-ceramic restorations we should be aware that after the years there is a high possibility that an unsightly gray color will be revealed at the gum line, which can be due to either receding gums or oxidation of the metal. Of course, something like this cannot happen if we bring all-ceramic restorations since they are manufactured without metal!
All-ceramic cases are also an indirect aesthetic technique, which is mediated by the dental laboratory, and is usually completed in four appointments at the dental office .
