Effect of material bulk and undercuts on the accuracy of impression materials
The Journal of Prosthetic Dentistry
|December 1, 1985
Abstract:
A truncated cone-shaped chromium steel die was used to determine the influence of the bulk of elastomeric impression material and size of undercut on the dimension of stone dies. It was found that both conditions affect the accuracy of stone dies. The possible clinical implications of the inaccuracies were discussed.
