A study of interocclusal record materials.

An investigation of casts assembled by the use of seven interocclusal record materials and manipulated by three operators disclosed that: 1. Aluwax was the most variable and least reliable of all materials. 2. Superbite consistently resulted in open cast relationships. 3. The five elastomers consistently resulted in the least amount of errors. 4. The two different thicknesses of elastomeric records resulted in statistically significant different mounting discrepancies. 5. On an average, an inexperienced student performed as well as the two experienced dentists.
