A technique for characterizing casting behavior of dental alloys has been
developed and tested. The method employs easily reproducible specimen
patterns and uses equipment and procedures generally available in dental
prosthetic laboratories. A castability value is arrived at by counting
complete segments of a cast alloy grid. Test results indicate that the
castability evaluation procedure described can be a valuable aid in the
laboratory for both selecting and using dental materials for producing cast
restorations. The test method would also appear useful for the evaluation
of products and techniques during research and development. An absolute
minimum for the castability value determined relative to clinical and
laboratory efficacy has yet to be established.
