Evaluation of the color and translucency of glass-infiltrated zirconia based on the concept of functionally graded materials.

Statement Of Problem: Infiltrated zirconia has promising mechanical properties. However, information about its optical behavior is scarce.

Purpose: The purpose of this in vitro study was to evaluate the color and translucency of zirconia submitted to infiltration and aging.

Effect of surface and heat treatments on the biaxial flexural strength and phase transformation of a Y-TZP ceramic.

Purpose: To evaluate the effect of grinding and airborne-particle abrasion on the biaxial flexural strength (BFS) and phase transformation of a Y-TZP ceramic, and examine whether sintering the veneering porcelain renders the previous heat treatment recommended by the manufacturer unnecessary.

Materials And Methods: Lava zirconia specimens (N = 108) were obtained with the following dimensions: 14.0 mm diameter × 1.
