Evaluating Polyetheretherketone (PEEK) as a Superior Alternative to Titanium in Middle Ear Implants: A Finite Element Modeling Study

Year: 2024

Type: article

Abstract: This study presents a comprehensive finite element analysis (FEA) of hydroxyapatite (HA)-coated middle ear prostheses, evaluating the biocompatibility, mechanical integrity, and material suitability of polyetheretherketone (PEEK), titanium, and stainless steel in middle ear environments. Simulations assessed stress distribution, displacement behavior, and coating performance under auditory frequencies of 250–8000 Hz and an applied acoustic pressure of 90 dB. Results indicated that PEEK closely parallels titanium in stress tolerance and mechanical displacement, demonstrating reduced fabrication complexity and enhanced adaptability for HA coatings. This analysis supports PEEK as a practical and potentially superior alternative, offering insights into innovative material applications for middle ear prosthetic devices.
