There is no ceramic dental product that can simultaneously display, in a single material, characteristics of opacity and translucency or long lasting ageing mechanical resistance. Therefore, the manufacturers had offered ceramics for core building, opaque ceramic coverage for the construction of the dentin and translucent glazes to be used in layering techniques [1, 2]. For dental ceramic restorations, the manufacturing process presumes a high temperature sample heating treatment, over 1,100 o C, for applied aesthetic veneer and glazer. An important link was established between the heating treatment and cases of fractures and failure (delamination) of the ceramic core [3-5]. Even with very good optic results for aesthetic applications, the development of yttrium-stabilized tetragonal zirconia poly-crystal (Y-TZP), does not completely solve the problem of crack propagation caused by crystalline phase instability (monoclinic (M)/tetragonal (T) phase)[6-8]. For zirconia ceramic, the problems are at the crystalline lattice level which is metastable, heating and cooling cycles augmenting T→ M phase transition. These problems are at the structural level and difficult to control [6-8].
