[Precision in fixation and remounting of cast parts]

The exactitude of transferring castings was tested in two currently used methods of casting. Results showed that alginate casting from a remontage matrix and simple casting with IMPREGUM are sufficiently exact for clinical purposes. When the mixing relations between the casting substances is exactly maintained a transfer exactitude of +/- 0.11 is achieved by the methods tested. When there is a change in the relationship of the mixtures deviations of up to 0.20 mm occur.
