Dimensional Accuracy of 7 Die Materials

Journal of Prosthodontics, 2005
Purpose: The purpose of this study was to compare the linear dimensional accuracy and the handling characteristics of 7 die materials. Materials and Methods: A master die analogous to a complete veneer crown preparation was machined from medical grade stainless steel, and 3 measurements (1: vertical; 2 and 3: horizontal) were

Evaluating Dimensional Accuracy of Stone Models

Journal of Dental Research, 1979
An optical feeler measuring technique was introduced for evaluating the dimensional accuracy of indirect stone models. It presents the following advantages: being able to measure the diameter of specimens in detail at various heights, indicating good reproducibility of the data; and hardly in juring the surface of the stone casts.

Resolution and accuracy in two dimensional echocardiography

The American Journal of Cardiology, 1981
The resolution and accuracy of commercially available two dimensional echocardiographic systems were tested by imaging two types of in vitro test objects. One consisted of a series of fine parallel threads spaced at known intervals and the other was a tissue phantom in which a series of holes of known size had been cut.
