Purpose: This study was performed to measure the accuracy of adjustable dental impression
trays by a scanning laser three-dimensional digitizer.
Materials and methods: The metal stock, individual, and adjustable stock trays were used
for 60 stone casts(10 casts each) duplicated a resin master model of mandible and maxilla. The
type IV dental stone was poured in a vinyl polysiloxane impressions and allowed to set for one
hour. The master model and the duplicated casts were digitized using an optical digitizer. The distance
between the reference points were measured and analyzed on the graphic image of 3-D graphic
software(CATIA version 5.0). The statistical significance of the differences between the
groups was determined by a two-way ANOVA.
Results: There were no significant differences between the accuracies of the adjustable
stock tray and the master model except only anterior arch width on the upper arch and the diagonal
arch length and arch length on one side of the lower arch.
Conclusion: The adjustable stock trays showed clinically acceptable accuracies of the study
cast produced by them.
