Stress Relaxation Properties of Five Orthodontic Aligner Materials: A 14-Day In-Vitro Study
Bioengineering (Basel). 2022 Jul 28;9(8):349. doi: 10.3390/bioengineering9080349. ABSTRACT We aimed to investigate the stress relaxation properties of five different thermoplastic aligner materials subjected to 14 days of constant deflection. Five different thermoplastic aligner materials were selected, whose elastic properties varied: F22 Evoflex, F22 Aligner, Durasoft, Erkoloc-Pro and Duran. The static properties of these materials-in particular,…
