摘要: Dental implants are nowadays commonly used as replacement for natural teeth when get damaged due to injury, infection or old age. Despite high success rates of implantation, complications and failures still occur. The aim this study is predict fatigue life commercially available implant system using FEA verification by analytical method. Implant basically a mechanical screw made titanium alloy Ti–6Al–4V with threads on its periphery. A three-dimensional finite element model (FE model) prosthesis (implant, abutment, fitting crown) modeled linear isotropic material properties implant, cortical bone cancellous commercial software code. Occlusal load (vertical lateral) applied static the crown find stresses around implant–bone interface. Analytical approach implant. Good correlation observed in method results. useful better understanding stress concentration location systems. Guidelines selecting best can be suggested.
