ABSTRACT

Feasibility of 3Y-TZP for dental implant abutment was evaluated under the Hertzian cyclic fatigue by examining the extent of the indentation damage and strength degradation. Fatigue test was conducted at contact loads of 500 to 3000 N and up to 106 cycles in exact in vitro environments. At 500 N, no strength degradation and crack generation was observed up to 5?05 contact cycles. As load rose, the dramatic reduction in strength was observed when the damage transition from ring to radial crack occurred. The extent of strength degradation was more pronounced in vitro environment probably due to chemical corrosion of artificial saliva through cracks introduced during large numbers of contacts.
