A comparative study of synthetic cast material strength.

The strength of five commercially available synthetic orthopedic casting products are discussed. Using three testing designs, significant differences could be consistently determined. These testing methods provide a means of comparing the various casting products on the market. The authors point out that this study was a comparison of ultimate strength only, and did not compare the other characteristics of the products. It also was noted that all these synthetic casting materials were stronger than plaster-of-Paris casting material.
