title: [Technological and clinical studies on various plastic filling materials].
abstract: The authors determined the hardness, water absorption and thermal expansion of different composites. The clinical trial of two of these materials is followed by conclusions as to their use in practice. With regard to the anterior region, the composites are in a sense an enrichment of assortment of filling materials. But due to their still insufficient physico-chemical properties, they are no alternative of cast or amalgam fillings.
