Bioinspired porous dental implants using the concept of 3D printing to investigate the effect of implant type and porosity on patient's bone condition

Abstract

This study aims to design titanium (Ti) porous (18–77% porosity) dental implants with conical and cylindrical types for standard and weak bones using 3D finite element (FE) models. The strain intervals of the mechanostat criterion were used to analyze strain intensity. Highly porous implants with the stiffness of 9 GPa and 18 GPa in weak bone produced a very high strain intensity (>3500 µε) which may eventually cause a bone fracture, however, stiffness of 76 GPa and bulk titanium implants in standard bone produced a very low level of strain intensity (<500 µε) which may lead to the bone resorption.
