Full maxillary rehabilitation with an all-ceramic system.

With the appearance of all-ceramic systems, providing a choice of framework porcelains and allowing the same material to be used for the veneer, it is now possible to select the ideal structure in terms of both function and aesthetics. Silicate ceramics allow porcelain laminate veneers and crowns to be used in the anterior region, providing excellent aesthetics; while for the posterior area, where function takes precedence, oxide ceramics, specifically zirconium oxide, are preferred. The IPS e.max ceramic system, heir-apparent to the IPS Empress 2 system, combines the advantages of zirconium oxide ceramics (IPS e.max Zircad) with the excellent aesthetic qualities of silicate ceramics (IPS e.max Press). This paper presents a clinical case requiring complete maxillary rehabilitation for aesthetic purposes. An overview of some of the porcelains used in this system, analyzed from both the clinical and laboratory perspective is provided. The aesthetic advantages of a single ceramic veneer, the need to select appropriate ceramics for anterior and posterior regions, and cementation and surface treatments are discussed.
