Objective: to evaluate the clinical results of a tetracycline-stained
type IV case report corrected with no core felspathic veneers, in order to
preserve maximum tooth structure.
Methods: after orthodontic treatment, a wax-up was performed for the
treatment planning. Internal bevel gingivectomy was carried out to reduce gummy
smile. Two months later, a clinical bleaching with Norblanc Office
(Laboratorios Normon, S.A. Madrid, Spain) activated with plasma light was
carried out and reinforced for 6 weeks with Whitening Polanight 16% carbamide
peroxide (SDI Limited, Baywater Victoria, Australia) at home.
After the conservative veneer preparation an immediate dentine sealing
was performed and final impressions were done. The laboratory drew up the
veneers with parallel stratification masking technique. Veneers were luted by
using a light-cured (RelyX Veneer, 3M) adhesive system.
Patient was recalled after 1 week, 1 month and once a year during 3
years respectively. Modified Ryge criteria was used to evaluate the
restorations state.
Results: the results obtained by the modified Ryge test were favorable
after three years follow-up.
Conclusion: no-core feldspathic veneers using “the
parallel stratification masking technique” probed to be a reliable choice for
the correction of tetracycline-stained teeth over a 3 years period
