title: [Occlusal surfaces of glass-ceramic (Dicor) and VMK-crowns compared by electron scanning microscopy].
abstract: The surface of painted and unpainted glass ceramic-crowns (DICOR) was compared with that of ceramometallic-crowns by the means of the Scanning Electron Microscope (SEM). If handled correctly and accurately glass ceramic presents a superiorly surface-quality. A disadvantage is the great thickness of the paint, that forces to make a compromise in the occlusal region: here we should prefer the advantage of the possibility to make a correct occlusal relation to the antagonist tooth with wax-pattern to a homogenous smooth surface. Ceramometallic crowns should get a real glazing finish and we have to set value on a correct modelation of the frame and an optimal veneer at the crown margin.
