Resumen

GRANDON, Fernando et al. Ammonium polyfluoride as an alternative for the surface conditioning of ultrathin lithium disilicate veneers. A case report. Int. j interdiscip. dent. [online]. 2021, vol.14, n.1, pp.44-47. ISSN 2452-5596.  http://dx.doi.org/10.4067/S2452-55882021000100044.

Ultrathin glass-ceramic veneers are a conservative approach for the restorative treatment of aesthetic disorders in the anterior region. However, surface conditioning with hydrofluoric acid of the thin structures can be usually a challenging step. Therefore, the use of a self-etching ceramic primer containing ammonium polyfluoride (Monobond Etch&Prime, MEP) offers a simplified technique with a reduced risk of overetching. Here we present an 18-month follow-up of ultrathin glass-ceramic veneers conditioned with MEP only.

Case.

Young female patient with an aesthetic disorder in the front region. The four upper incisors were conservatively prepared for ultrathin lithium disilicate (e.maxPress) veneers. Pre-treatment of the glass-ceramics consisted only of MEP application, followed by adhesive cementation with Variolink Esthetic LC. At the 1.5-year recall, the restorations appeared undamaged, with no marginal gap or staining.

Conclusions.

MEP constitutes a promising alternative to hydrofluoric acid for the adhesive cementation of glass-ceramic veneers.
