Ángel Torres-Nebril, Vicente Faus-Matoses, Ignacio Faus-Matoses, Teresa Alegre-Domingo, Vicente J. Faus-Llácer.


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
