[Follow-up study of accuracy of fit of crowns, prepared for phantom head under practice conditions].
Mesial, distal, oral and vestibular measurement of fissure spaces in 39 crowns and 51 bridges (divided with interlock-connection) made in the context of propedeutic instruction showed a mean marginal discrepancy of 62-90 microns in a range of 30-160 microns. A simple method to evaluate the fissure space was described. In actually discussion the results would be helpful to determine criterions for quality on fixed restorations.
