Advantages and limitations in the use of porcelain veneer restorations.

Porcelain veneer restorations including preparations, impression materials, cast materials, refractory casts, handling of porcelain, the try-in, and the final luting are discussed. Techniques are described to increase marginal accuracy, establish predictable natural polychromatic color within the porcelain, establish good contours and surface textures, and shorten final placement time. Tooth preparation is routinely recommended, as is the combination of epoxy dies, refractory casts, and anatomic buildup techniques. Emphasis is placed on a close working relationship and communication among the dentist, dental technician, and patient.
