Numerical Analysis of Mechanical Behavior using Bio-Compatible Material of Dental Prosthesis- A Finite Element Analysis

Abstract

Engineering technologies have influenced a decisive function in the development and advancement of dental implant technology. From the design and manufacturing of biocompatible materials to the development of software for CAD modeling and simulation, engineering plays a crucial role in creating safe and effective dental implants. Techniques like finite element analysis have been accustomed to simulating the stresses and strains on implants helping to optimize the design and insertion process. Dental implants are prosthetic devices that are used to replace missing or damaged teeth. They are typically made of biocompatible materials like titanium or ceramic and are surgically inserted into the jawbone. The use of dental implants has emerged as increasingly popular in recent years due to their many benefits over traditional dentures or bridges. The thesis discussed in this abstract aims to compare the stress profiles of PEEK and Titanium dental implants during different stages of implant insertion depths. The study builds bone-blood interface CAD models using Solid Works and performs simulations using ANSYS. The results indicate that PEEK is potentially capable to replace Titanium as a suitable material for dental implants. Additionally, the study evaluates von Mises stresses in cortical and cancellous bone and considers the impact of torque and insertion depth on stress profiles, as well as strain and deformation calculations. However, it is a pivotal point to note that the study is determinate to simulation-level analysis, and some assumptions were made, such as the absence of rotation during implantation. It is deduced from the results of Frost’s mechanostat theory, for strain which is equipped for long bones, cannot be viable to facial bones. In conclusion, this study provides exquisite intuitions into the usage of bio-compatible materials in dental implants and offers an enviable keystone for subsequent time research. Future studies can consider variations in the torque exerted for the time between the implantation process and upgrades to software efficacy to simulate the dynamic process of implantation. By improving our understanding of dental implants, we can continue to embellish patient outcomes and the eccentricity of existence.
