When there are significant cavities, teeth with large fractures, devitalised teeth (cured root with loss of vitality = more fragile tooth), covering it with a ceramic capsule is recommended.
Nowadays with the advent of new technologys and very resistent aesthetic materials like zirconium, it is possible to do without the underlying metal shell both for singular teeth and small bridges (replacing one or two missing teeth). The absence of metal makes it possible to overcome inevitable imperfections (gray border) that are encountered with the previous ceramic-metal crowns.

Ceramic is a biocompatible, non-allergenic material and this can be an advantage for allergic patients. The elevated transparency of these materials allow light to penetrate like on natural teeth, making the product look similar and maintaining at the same time optimum resistance. Applying one or more ceramic crowns, other than protecting and reinforcing the tooth, allows us to proceed with simultaneously correcting imperfections like strong discoloration that cannot be corrected with simple whitening, or lightly correcting position and shape (diastemas).
In the front section, when teeth aren’t damaged but only need small corrections, simple ceramic veneers should be considered that need a less invasive tooth preparation
