Systems Factorial Technology is a powerful framework for investigating the fundamental properties of human information processing such as architecture (i.e., serial or parallel processing) and capacity (how processing efficiency is affected by increased workload). The Survivor Interaction Contrast (SIC) and the Capacity Coefficient are effective measures in determining these underlying properti...

The high crystalline content ceramic systems have been developed in an attempt to improve the strength of metal-free restorations as well as deliver more esthetic results than conventional metal-fused-to-ceramic restorations (Ozcan et al., 2001; Valandro et al., 2006...

Gingival retraction or dilation is an important procedure in the fabrication of fixed prostheses. Quite often, the margins of these restorations are placed very close to the gingival margin, or even subgingivally, for aesthetic and functional reasons. Therefore, the operating surgeon must correctly record the prepared cervical finish line to enable adequate marginal integrity for the restoratio...
