Zirconia – cementing or luting

Abstract

Despite the biocompatibility and perfect aesthetics of dental ceramics,
failures are still of considerable concern because of some problems
that are clinically experienced. There is limited information about the
retentive strength of luting agents for zirconium oxide-based crowns.
On the market there are different types of cements that are available
for fixating of zirconia restorations. So far there is no consensus
regarding the best protocol for zirconia luting used in dentistry.
Zirconia core-based ceramics are highly resistant to chemical
attack from hydrofluoric acid and a different approach is required if
clinician elects to bond these restorations using resin-based adhesives
and luting cements. Optimal surface preparation is mandatory to
ensure clinical success when cementing\luting a zirconia restoration.
Although zirconia for dental restoration is used already for decades,
the best method to ensure a stable bond between the zirconia and
tooth structure is still questionable.
