Porcelain laminate veneer provisionalization using visible light-curing acrylic resin

Placement of porcelain laminate veneers has become a relatively common procedure. Occasionally it is necessary to fabricate provisional restorations. For these situations, the use of self-curing acrylic resin and composite resin has been described in the literature. Extensive trimming and finishing procedures are often necessary, and because of the inherent fragility of the materials, the provisional restorations are prone to breakage. To improve the technique, visible light-curing acrylic resin can be used to fabricate direct provisional restorations. The material is available in several shades, has excellent manipulative properties, and does not necessarily require a custom matrix, offering significant advantages over a composite resin or self-curing acrylic resin.
