ABSTRACT
Aim: To predict the fatigue life of an implant with the correlation of the applied forces by finite element analysis.
Methods and Material: The authors of the study have created a 3D model of the bridge supported by an implant. The implant material used was titanium alloy. A finite element analysis was conducted to calculate the maximum amount of stress and deformation formed in the implant and the bone on the application of a force of four different magnitudes- 250N, 500N, 750N, 1000N. By conducting a fatigue analysis, the minimum, average, and maximum amount of days the implant can survive under the applied forces was calculated.
Results: The maximum amount of stresses and deformation was observed at the abutment screw bone junction. The implant could withstand a force of 250N for an average of 8 years and a force of 1000N for an average of 2 years. With constant increase in the force, the lifespan of the implant decreased as the bone could not withstand the force.
Conclusions: Finite Element Analysis is a very useful tool to predict the mechanical properties of implants in dentistry and analyze the survival of the implant by calculating the fatigue analysis.
