Preclinical assessment of a technique alloy for teaching cast restorations

The performance of second-year preclinical students who fabricated cast restorations with a technique alloy were compared to the performance of students who used a conventional gold alloy. Nine categories of casting fabrication were evaluated, and no significant differences in performance were found between the two groups of students. Thus, technique alloys can be used as economical substitutes for gold alloys in preclinical teaching situations.
