Procedure for combining a facial porcelain veneer with a metal lingual and occluding surface.
This article describes a procedure for making a crown that combines an all-porcelain facial veneer with a metal lingual and occluding surface. The procedure combines both the conventional lost wax technique and the use of a refractory cast for firing porcelain. The crown retains the advantages of the traditional all-porcelain crown restoration but reduces the risk of damage to the opposing teeth associated with an all-ceramic occluding surface. Furthermore, compared with porcelain, the metal surface allows more control over the occlusal and lingual contours during construction of the crown. Although the construction of the anterior crown is described, the procedure is equally applicable to posterior full-coverage restorations.
