The direct resin restoration has probably been used most extensively in Class II situations. Problems with Class II direct resin restoration include difficulty in developing proximal contact, occlusal wear, and polymerization shrinkage. Beta-quartz glass-ceramic inserts have been developed in an attempt to reduce the incidence of these potential problems. They can be placed in a one-appointment technique, are relatively inexpensive, and can readily be utilized by the clinician adept in placing Clas s II composite resin restorations.
