Clinical procedures for improving veneered metal crowns.

Satisfactory design and preparation of the veneer window presuppose that a perfect or a near-perfect preparation of the tooth has been made. The window is not just a cutout and is not the responsibility of the laboratory technician. Whenever optimum gingival health, a satisfactory esthetic result, and a long-lasting restoration are desired, it is worthwhile to carefully check and, if necessary, adjust the veneer window directly in the mouth before the veneer is added. This is especially important in restorations that extend below the gingival margin.
