Resumo
This clinical report elucidates both uses of direct and indirect restoration techniques, in
which a failure of the direct resin restoration after one year by tooth discoloration relapse
was detected, and a ceramic veneer restoration was the final elected treatment. A poor
marginal adaptation and mismatching color of a class IV resin composite restoration was
observed, which was placed due to a traumatic dental injury, in which part of the enamel
and dentin was lost but without tooth vitality impairment. Tooth bleaching was performed
combining home and in-office bleaching techniques, followed by restoration replacement
with resin composite in order to improve the dental esthetic. After one year of follow up,
it was observed that the restored tooth was darker and the resin shade mismatch the tooth
color, showing an evident restoration margin. In attempt to achieve a long lasting treatment,
substitution of the direct composite by an indirect restoration was selected, using a unit
ceramic veneer restoration, and followed up for four years. Conservative approaches should
be the choice treatment in restorative dentistry, however the re-incidence of discolored tooth
or the restoration material degradation must be taken into consideration before indicating a
direct or indirect restoration.
