Finite Element Analysis of Magnesium AZ31B Materials for Biodegradable Bone Screw Application

Irza Sukmana

Abstract


The bone implant functions for the load bearing and aims to support the integration of fractured bone. It may increase the strength of the broken bones and also at the same time support bone regeneration and integration. Bone screws are usually attached to the implant plate and bonded to the surface of the fractured bone by screwing the bone screws through the bone structure. In its implementation, a non-degradable implant needs a second operation for the patient to take out the implant. Currently, biomedical researchers are trying to produce bone implants that are degradable or bioresorbable materials. Magnesium (Mg) alloy is a potential biomaterial for bone implants, as Mg is a degradable material. Mg is one of the elements needed and harmless to the human body. This study focuses on finite element analysis (FEA) for the bone screw design of Magnesium alloy that has been well known as a potential candidate for biodegradable bone screw and plate application. The three dimensions (3D) design was done by using Solidworks software, and finite element analysis was performed using ANSYS by calculating the moment, pullout, and force bending received by bone screws. The validatation results of the design carried out with several analytical tests before the production of bone screws is proposed. The FEA simulation of bone screws pullout has a total deformation of 0.028 mm and a von Mises stress of 134.25 MPa for a pullout load of 1100 N. The bone screws torsion with a torque of 883 N.mm, the total deformation is 0.988 mm and for bone screws bending with a total deformation of 5,4352 mm has a von Mises stress of 25.706 MPa. AZ31B bone screws, based on the design, are safe and capable of handling the maximum load and deformation during the implantation. In vitro biocompatibility and in vivo studies is needed for further assessment of the design.
