• Abstract

  The present study will evaluate the failure probability of crowns with or without glass infiltration in the zirconia structure, with conventional or bioinspired structures, using Weibull analysis after fatigue. The stress distribution in the crown by the Maximum Principal Stress criteria will be also assessed. One hundred anatomical preparations will be used, and divided into 4 groups: Tr…

• Abstract

  The present study will evaluate the fatigue life of completely or partially porcelain / glaze covered crowns, determining their reliability with Weibull analysis. The null hypothesis is that there will be differences in the reliability of the types of crowns. Seventy-two intact molars will be used, which will be prepared for full crown and divided into three groups (n = 24): traditional z…

• Abstract

  Zirconia has been a material widely used as infrastructure of dentures, due to its excellent physical and mechanical properties. Objectives: 1. To assess the influence of wear caused by abrasion sandpaper grits in different roughness, phase transformation percentage, biaxial flexure strength and reliability analysis of a zirconia-based ceramic partially stabilized by yttrium oxide; 2- To …
