ABSTRACT
With the recent introduction of new high strength dental porcelains, laminate veneers and all porcelain crowns, inlay and onlay restorations are becoming increasingly popular. Because these materials possess such high strength and hardness, it is possible, in certain carefully selected clinical situations, to construct short-span anterior fixed bridges by incorporating a pontic with two modified laminate retainers. Two clinical cases are presented to illustrate how this technique can be successfully utilized to achieve an excellent esthetic and functional result in a truly conservative manner.

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.
