“…On the other hand, G1 showed greater density than the other two groups, although differences were only significant between G1 and G3. This apparent inconsistency is probably related to the different densities of zirconia crystalline phases [5]. The influence of porosity on flexural strength of ceramics is relatively drastic.…”

The aim of this study was to evaluate the dependence of sintering conditions on mechanical properties and microstructure of zirconia stabilized by yttria. Commercial blocks of pre-sintered of zirconia stabilized (DeguDent Dentsply, Germany-Cercon) were investigated in this study. The blocks belonging to group 1 were sintered under the recommended conditions by the manufacturer (1350°C for 6 hours). The blocks of group 2 were sintered under 1500°C for 6 hours. The blocks of group 3 were sintered under 1350 C for 14.5 hours. The results indicated that the sintering conditions influenced the mechanical properties and microstructure of zirconia. The three sintering conditions analyzed in this study produces zirconia bodies with properties adequate to be used in clinical function. However, the decisive factor for change in the sintering conditions should be the cost/benefit during the prosthetical process and longevity of clinical material to perform its function in the oral cavity.

“…10 Another option is the ZrO 2 composites with bioglass additions, which at low concentrations of the bioglass reach high values of fracture toughness in the order of 6.3 MPa•m 0.5 , although this research focused only on the improvement of mechanical properties, without considering or evaluating the degradation behavior of these compounds. 11 Also the use of Al 2 TiO 5 as a reinforced material of Al 2 O 3 has been suggested due to its excellent mechanical properties and good biocompatible characteristics. 12 However, until now there are no papers in which any study of the use of Al 2 O 3 /Al 2 TiO 5 as a biomaterial is reported.…”
