Currently the discussion about the use of composite materials for posterior teeth is controversial. Although practiced by many dentists, the method has not been universally accepted. The function of this filling material is impaired by its insufficient wear resistance and polymerisation shrinkage, and improvements of clinical application are the only means to prevent marginal gap formation and early secondary caries. In view of these shortcomings all dentists should use composite materials for posterior teeth only in carefully selected indications.
