In vitro marginal adaptation of alumina porcelain ceramic crowns
. J Prosthet Dent 1994;72(6):585-90.
The high demand for aesthetic dental restorations made ceramic crowns
Material and Methods: The thickness of functional and non-functional cusps for both complete cast and metal ceramic crowns
fabricated in the dental laboratories of multiple teaching hospitals were measured using Iwanson gauge.
In vitro retentive strength of zirconium oxide ceramic crowns
using different luting agents.
In 2012, Biacchi and Basting compared the fracture strength of 2 types of full ceramic crowns
: indirect conventional crowns retained by glass fibre posts and endocrowns.
The ceramic crowns
were then cemented using the dual-cured version of the same cement.
He received a ceramic crown
(metal-free) rehabilitation on the upper teeth two years ago.

However, there are no particular specifications in relation to the clinically acceptable marginal discrepancy.4 May et al18 evaluated that a marginal gap at the crown and die interface of an all ceramic crown
in the posterior dentition was less than 70 micrometers.
Treatment planning was decided to restore the tooth with fibre-reinforced composite resin post and core ceramic crown
after root canal treatment.
