Purpose: This study compared the mechanical properties of In-Ceram Zirconia and In-Ceram Alumina. Materials and methods: Ninety-four disks and six bars were prepared with the slip-casting technique. The disks were used to assess biaxial flexural strength (piston on three ball), Weibull modulus, hardness, and fracture toughness with two methods: indentation fracture and indentation strength.

2007-11-1 Zirconia (ZrO 2) is a ceramic material with adequate mechanical properties for manufacturing of medical devices.Zirconia stabilized with Y 2 O 3 has the best properties for these applications. When a stress occurs on a ZrO 2 surface, a crystalline modification opposes the propagation of cracks. Compression resistance of ZrO 2 is about 2000 MPa. Orthopedic research led to this material being ...

IPS Empress crowns supported by zirconia abutments had the lowest fracture loads (p = .000). Fracture modes of metal-ceramic crowns supported by titanium abutments included screw fracture and screw bending. Fracture of both crown and abutment was the dominant mode of failure of In-Ceram/IPS Empress crowns supported by zirconia abutments.
