Simulation of Mechanical Behavior of Dental Implant Made Of Shape Memory Alloy Using the Finite Element Method

Shape-memory alloys (SMAs) hold a prominent place in medical and dental applications due to their high compatibility with the body, corrosion resistance and, unique mechanical properties. The aim of this study was to assess the influence of SMA dental implants on the stress distribution of the implants and bone. A dental implant was subjected to axial and transverse forces and the results were extracted using finite element methods. To this end, a sample of an existing dental implant with a section of the bone was simulated using Abaqus software and analyzed statistically. Finally, the magnitude of stress in the SMA implant was compared with that of the implant made of common materials. The magnitude of stress in the SMA implant was lower, compared to that of nickel-titanium implant. Moreover, the nitinol implant at the points which were under higher force and stress showed lower levels of the transformed values of stress to the jaw bone, compared to the nickel-titanium implant.
