Multiple porcelain veneers: a temporization innovation--the peripheral seal technique.
Porcelain veneers, despite all appearances to the contrary, rank as one of the most demanding and technique sensitive applications in esthetic restorative dentistry. Given the minute dimensions of these restorations and the partial nature of coverage, the temporization of multiple veneers provides clinicians with a notable challenge. The optimum placement of porcelain veneers depends on the clinician establishing and maintaining the patient's gingival health during the provisional treatment phase, so that there is no opportunity for inflamed sulcular tissues to compromise the final adhesive effort. This is best achieved using provisional restorations with the correct emergence profile, as well as accurate and amply sealed restorative margins. The purpose of this paper is to introduce a new temporization technique for multiple veneers that assures predictable marginal fidelity, allowing for a "temporary" yet adequate seal of the acrylic facing the dental substrate, and elective detachment at the definitive bonding appointment.
