title: Posterior composite technique utilizing directed polymerization shrinkage and a novel matrix.
abstract: A technique is described for novel placement of posterior composites. Two frequently encountered problems are eliminated with this technique: difficulty in achieving good interproximal contacts and composite shrinkage away from the tooth. The desirability of indirect composites is questioned in view of recent research and the technique for direct composites described.
