Development of a dental three-dimensional laser scanning system and measure the accuracy of new adjustable upper and lower dental impression tray was performed. The master model and the duplicated casts were digitized using an dental scanning system. The distance between the reference points were measured and analyzed on the graphic image of 3D graphic software of CATIA. The statistical significance of the differences between the groups was determined by a two-way ANOVA. 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 and lower arch. The adjustable upper and lower stock tray showed clinically acceptable accuracies of the study cast produced by them.
