[New procedures for resin-metal bonds. A comparative in-vitro study].
Since 1984 it has been possible to create a chemical bond between dental alloys and composite resins resembling the metallo-ceramic bond. Modern systems based on silanization (Rocatec, Silicoater MD, and Spectralink), in connection with the specific resins used in these systems (VisioGem, Dentacolor, and SR-Isosit-N), were tested for their bond strength to 9 common dental alloys (of 7 different types) with regard to shear strength, the topography of the fracture surfaces, and metallographic microstructure transformations. No major structural transformations were observed for any of the systems tested. A notable degree of interdependence was seen in the Silicoater MD system whose bond strength to non-precious alloys (among others) was the lowest in the test. The Rocatec system, on the other hand, showed a superior bond to all types of alloys, especially to pure titanium.
