Mechanical properties and suitability of PLA for 3D-printed dental implants: Experimental and simulation analysis

Abstract

This study investigates the mechanical properties of Polylactic Acid (PLA) in 3D-printed medical implants, focusing on dental applications. PLA, significantly lighter than traditional titanium implants, reduces stress on the jawbone and surrounding tissues, improving patient comfort. The research evaluates PLA's mechanical and structural properties through computational simulations, experimental studies, and data analysis. Mechanical testing, including tensile and compressive strength assessments, was conducted to determine PLA's suitability for dental applications. Finite Element Analysis (FEA) was used to simulate mechanical behavior under various loading conditions. Results indicate that while PLA demonstrates good biocompatibility and ease of fabrication, its mechanical strength is insufficient for permanent dental implants. However, its properties make it a promising material for temporary dental applications. The findings provide valuable insights into the relationship between PLA's properties and implant performance, guiding future research on material modifications to enhance its applicability in medical implants.
