The Optimization of Ti Gradient Porous Structure Involves the Finite Element Simulation Analysis

Titanium (Ti) and its alloys are attracting special attention in the field of dentistry orthopedic bioengineering because their mechanical adaptability biological compatibility with natural bone. The dental implant is subjected to masticatory forces oral environment transfers these surrounding bone tissue. Therefore, by simulating behavior implants tissue we can assess effects on growth quite accurately. In this study, different gradient pore structures that consisted simple cubic (structure a), body centered b) side c) were designed, respectively. strength designed porous was simulated three-dimensional finite element simulation technique adaptation stress-strain distribution within examining fretting implant-bone interface. results show maximum equivalent stress strain increase porosity. a smaller difference between outer inner structure more uniform. So, a-b type exhibited less concentration. For structure, when porosity 40 47%, range normal growth. When subject lingual buccal stresses, an higher achieve uniform cancellous than low implant. Based results, improved fixation implant, optimum parameters should be: average 46% 13% (b structure) 59% (a structure), sized 500 ?m. With optimized optimal ingrowth into thus provide stable achieved 99 MPa, which far below yield 299 MPa.
