Numerical analysis of the mechanical behavior of ceramic dental implants based on Ce-TZP/AlO composite.

This study aimed to identify the potential use of the ceramic composite ZrO(CeO)-AlO as a dental implant due to its intrinsic geometry and different masticatory loads based on finite element simulations. Ceramic samples were sintered at 1500 °C-2h, and characterized: The mechanical properties of the ceramic composite (hardness, fracture toughness, flexural strength, Young's Modulus, and Poisson ratio) were determined, in addition to the relative density and its structural characteristics. Commercial dental implant designs (incisal and third-molar) on CAD models were used in this study as an initial implant geometry applied in a typical simulated mandible anatomy.

Experimental analysis and numerical simulations of the mechanical properties of a (Ce,Y)-TZP/AlO/H6A ceramic composite containing coupled toughening mechanisms.

Objectives: This study investigates the simulation of the mechanical behavior of a bioceramic composite based on (Ce,Y)-TZP reinforced with equiaxed AlO and platelet-shaped hexaaluminate (H6A) grains using Finit Element Method (FEM).

Methods: A commercial (Ce, Y)-TZP/AlO ceramic powder was compacted into disc-shaped specimens that were sintered at 1500 °C for 2 h. The sintered samples were further subjected to hydrothermal degradation in an autoclave at 134 °C, 0.
