Material Design of Dental Implant for Minimum Stress Shielding of Bone Using Design of Experiment, Deep Learning, and Ashby Plot

Abstract

Nowadays, dental implants are one of the essential treatments for human beings to maintain their chewing function and aesthetics. But after surgery, the Young modulus promotes stress shielding and stress simulation at the bone-implant contact, thus decreasing the density of the bone and, due to bone resorption, the dental implant fails. In this article, a material property is determined using simulation in Ansys software and using Design of Experiments (DoE) Informed Deep Learning model, which is generated for minimum stress shielding. Ashby plot is used to determine the best possible dental implant material in which five materials are obtained. Titanium and ceramics are functional in medical fields, while steels are not functional due to biocompatibility issues. However, carbon fiber-reinforced polymer (CFRP) is biocompatible and excellent for dental implants, but needs manufacturing attention. Nickel alloys can also be used for dental implants, however, their biocompatibility and technical difficulties need to be studied.
