Comparative Evaluation of Symmetrical Titanium and Polyetheretherketone (PEEK) Hollow Structures for Mandibular Reconstruction: Strength, Geometry, and Biomechanical Performance

Symmetry, Journal Year: 2025, Volume and Issue: 17(4), P. 499 - 499

Published: March 26, 2025

This study introduces a novel titanium hollow structure for mandibular reconstruction designed to optimize mechanical stability and stress distribution. A comparative evaluation with similar polyetheretherketone (PEEK) is performed assess material-specific biomechanical behavior. Methods: Finite element analysis (FEA) simulations were conducted evaluate distribution, displacement, structural of the symmetrical PEEK structures under physiological conditions. The reconstructions based on Scherk minimal surfaces, integrating fixing plates achieve optimal performance while maintaining symmetry. Results: FEA demonstrated that exhibited higher stability, lower more uniform ensuring integrity applied forces. In contrast, displayed greater flexibility, which reduced shielding but resulted in deformation load-bearing capacity. While inherently supports osseointegration, requires surface modifications enhance bone integration long-term stability. Conclusions: presents promising advancement metal-based reconstruction, effectively balancing strength, durability, biological integration. Future research should focus using structures, enhancing optimizing lattice further improve PEEK-based titanium-based implants

Abstract This research aims to explore the influence of post‐curing time and layer thickness on tensile characteristics various triply periodic minimal surface (TPMS) structures produced by mask stereolithography (MSLA). The study determined best duration, thickness, TPMS lattice type improve ultimate strength (UTS) absorbed energy. To experimentally evaluate characteristics, a dog bone‐shaped specimen was utilized. Three distinct structures, Gyroid (G), Neovius (N), Diamond (D), were present in test region. After investigating many process factors with response methodology (RSM), optimization methods are applied find their printing procedure. work shows novel use RSM optimize parameters structure mechanical properties during manufacturing. According results, biggest factor affecting UTS is while most significant increasing energy curing time. optimal operating for MSLA based results 0.05 mm, period 40 min, N. optimum responses corresponding as 7.16 MPa 18.16 J Highlights Optimized production geometries. Compared performance. Identified input absorption. Conducted comprehensive experimental evaluations validate optimization.
