All-porcelain
(ceramic) crowns without metal core are distinguished
by their excellent aesthetics. Light is not only
reflected, there is also real transparency as
seen in natural teeth. This effect makes the
all-porcelain crown perfect for use in anterior
areas, whereby minor form and alignment corrections
are also possible.
A further advantage of the metal-free ceramic crown
is the tooth-shaded margin, which need not be placed
under the gum line. Thus, the crown margin does
not irritate the gingival tissue and prevents gum
recession.
Porcelain (ceramic) is an extremely biocompatible
material with no allergenic potential. This can
be a real advantage to predisposed (allergic) patients.
With smaller defects, limited to the outer surface,
we prefer treatment using porcelain facings (veneers),
allowing more of the natural tooth to be preserved
during preparation.
Progressive development in ceramics brings forth
ever stronger materials, such as zirconium ceramic.
Therefore, it is now possible to fit metal-free
porcelain crowns in the posterior area.
