Sažetak

Since 1936, when the PMMA synthetic substances were first used in dentistry, some substantial changes have taken place in this branch. These advances have led to an improvement in the management of defects of these substances such as inadequate resistance to wear by use, swelling due to absorption of water and formation on the border between the metal and a syntehtic facet, allowing bacteria in and resulting in a decrease or even loss of the esthetic aspect already after two years. These defects, though, could not be eliminated. Recognition of the formation of fissures on the border between the metal and a synthetic substance as the key problem leading to loss of
the esthetic quality of facets has resulted in a improvement of adhesive characteristics on the metal surface. Musil and Tiller have devolped a special system of layers, chemically linked to both the metal surface and the synthetic substance. A fissure-free junction between the metal and a synthetic substance in the Silicoater procedure provides new and better possibilities for use synthetic substances in dentistry. The following advantages have been observed: (1) use of a technique of telescopic crowns; (2) in cast prostheses; (3) in cemented glued bridgs (Maryland bridges); and (4) in orthodontics. A substantial improvement in the junction firmness, achieved by treating the surface by the Silicoater procedure, was ascertained in this study. Three base and two noble alloys with different surface preparation were mutually cemented glued together using composite synthetic substances.
