Sažetak

Since neither silicates nor autoacrylics have proved entirely satisfactory and do not fully satisfy the requirements of contemporary dental practice, composite materials have recently been introduced for fillings of class III, V and partly IVThe authors define the term of composite materials which consist mainly of a basic organic material and an inorganic part. The chemism, the physico-chemical and the clinico-biological properties of composite materials are reviewed. A retrospect is given to the comparison of properties of classic silicates and acrylics with composite materials on the basis of past laboratory and clinical investigations, conducted in many European, American and Japanese scientific circles. If one takes into consideration the effect of the centre of the oral cavity as the reaction of the live dental tissue, one may realize the seriousness and the sensitivity of the problem of obtaining a good and aesthetically satisfactory material for fillings of the front teeth. In this sense composites have brought a great improvement and opened better possibilities. With regard to the biological reaction of the live tissue and the problem of complete blending of the organic and the inorganic part of the composite mass and good adhesion of the same to the dental tissue, the authors consider that restrained enthusiasm would be well advised.
