[Investigation of accuracy of fit of partial crowns with different shaped margins].
The marginal adaptation of partial crowns with different types of finish line preparations was determined by means of dye penetration tests. The best marginal sealing was found for the featheredge-like preparation, followed by the shoulder preparation and the chamfer preparation with or without bevel. The scanning electron microscopic evaluation revealed that a finishing of the restoration margins during the setting of the luting material resulted in a better marginal sealing than a finishing after the cementation.
