Resumo:
The ceramics used in Dentistry have been highlighting in terms of longevity and clinical
predictability for aesthetic restorative treatments, mainly due to the strength and
durability of the bond between the tooth surface, the cementing agent and the
porcelain, besides providing a minimal intervention in the dental fabrics and an
excellent aesthetic result. The type of material and its possibility of being conditioned
with hydrofluoric acid added to the silanization of the porcelain was the advent that
provided a significant increase of the union of the ceramic with the cementing agent
being compared to the traditional conditioning with phosphoric acid of the dental
substrate added to the application of the adhesive system, which provided a major
advantage over conventional treatments. The objective of this work will be to describe
an oral aesthetic rehabilitation with ceramic laminates by means of a specific and quite
effective clinical and laboratory sequence and to emphasize the importance of the
internal preparation of the restorative material and the correct choice of cementing
agent to obtain excellent bonding results and longevity. The patient complained of an
aesthetic deficiency of her smile mainly in relation to changes in the color of the dental
substrates and, on clinical examination, it was possible to notice deficient composite
resin restorations besides visible changes in texture. The e.max type ceramic
laminates were installed in the elements 13,12,11,21,22 and 23, which underwent the
process of shielding and silanization of the part resulting in an excellent bond strength
and an excellent aesthetic result that was according to the expectations of the patient
and the dentist.
