Abstract

The purpose of this investigation was to evaluate the precision of optical impressio obtained with the Cerec-device. Cerec provides a linear correlation between z-data and altitude (r = 1), one bit representing 49 microns. Repeated measurements deliver pixel-z-data within a range of +/- 49 microns and surfaceaverages (484 pixel) within +/- 5 microns. Deviations occur near areas with parallel orientation to the direction of measurement.

Metal-ceramic bridges from commercial dental laboratories: alloy composition, cost and quality of fit.

The quality of construction of fixed bridge prostheses directly affects their long-term survival. The cost, alloy composition and marginal fit of bridges made by 30 commercial dental laboratories is assessed. Duplicate models of a three unit bridge preparation were sent to 30 different laboratories, as if required for a patient receiving treatment under the General Dental Service. Material was sent via general dental practitioners, requesting metal-ceramic bridges made from 45% Au alloy, precious metal or non-precious metal. Proximal contacts were overbuilt at 65% of sites and pontic tissue contacts were excessive in all but one bridge. Eight laboratories did not use alloys corresponding to the request made. The mean marginal gaps of non-precious metal bridges (145 microns) were significantly greater than those for 45% gold alloy (106 microns). Marginal fit was poor and a number of factors have been observed, with other postulated, which may have contributed to this problem.
