Biomechanical performance of poly-ether-ether-ketone (PEEK) vs. titanium orthodontic mini-screws in artificial bone: An in vitro investigation

Titanium mini-screws outperformed unreinforced PEEK screws across all mechanical tests, demonstrating superior torsional, pull-out, and lateral resistance. Additionally, larger-diameter screws (1.6 mm) showed better mechanical performance than smaller ones (1.4 mm) in both materials.

Abstract

Titanium mini-screws outperformed unreinforced PEEK screws across all mechanical tests, demonstrating superior torsional, pull-out, and lateral resistance. Additionally, larger-diameter screws (1.6 mm) showed better mechanical performance than smaller ones (1.4 mm) in both materials.
