Abstract

This study aims to analyze the von Mises stress, deformation, and safety factor in variations in dental implant materials (Ti-6Al-7 Nb and Y-TZP) and variations in thermal load (0°, 22°, and 70°) using the finite element analysis (FEA), namely the steady-state thermal solution and static structural. Loading at 225 N and type of teeth is posterior tooth model (Straumann Standard Plus Tissue Level RN). Abutment models, implant fixtures, and crowns varied with Ti-6Al-7Nb and Y-TZP materials, but the crown only used Y-TZP. The largest von Mises stress is produced by dental implants subjected to a thermal load of 70°C, while the lowest value is produced by dental implants subjected to a thermal load of 0°C. TTZ had the lowest von Mises stress of any dental implant variation, while ZZZ had the highest. TTZ dental implants are made up of a Ti-6Al-7Nb implant fixture, a Ti-6Al-7Nb abutment, and a Zir Y-TZP crown. All components of the ZZZ dental implants are made of Zir Y-TZP material, which has worse mechanical properties than Ti-6Al-7Nb. As a result, the von Mises stress is lowest at ZZZ. Ti-6Al-7Nb has better mechanical qualities than Zir Y-TZP. TTZ causes the least amount of stress when compared to other versions. At 70°C, the maximum displacement value for each dental implant variation occurs. The maximum displacement, however, is less than 4 µm, demonstrating that this value does not apply pressure on other bones in the mouth. The dental implants in this study were modeled using the FEA static structural analysis-steady state thermal analysis solution and were modified from 0.8 x European dental implant standards. Based on simulations on a variety of materials with a bite force of 225 N and thermal load (0°C, 22°C, and 70°C), all types of dental implants were judged safe because the factor of safety value was greater than 1. © 2025, Semarak Ilmu Publishing.
