[Accuracy of fit and margins of laboratory-finished SR-Isosit composite inlays].
30 inlays were produced exactly by manufactures instruction using the SR-Isosit composite. Before cementation the marginal gaps of the inlays extended to 280 microns occlusal resp. to 350 microns gingivoproximal. After insertion the thickness of the luting composite ranged from 40 to 400 microns occlusal resp. from 40 to 470 microns gingivoproximal. Dye penetration test indicated that only 43.7% of the inlays had a good marginal behaviour after storage in water over a six month period. Particularly remarkable was the insufficient junction between the luting composite and the highly polymerized inlay.
