Article Synopsis
- - The study aimed to assess the mechanical properties of Clear Aligners after they were used in the mouth for various lengths of time (7, 10, and 14 days) and compare them to new, unused aligners.
- - Researchers analyzed 32 aligners from four patients, conducting tests to measure elastic modulus, ultimate tensile stress (UTS), yield stress, and hardness, resulting in 96 samples and 16 samples of the raw material used for manufacturing.
- - Findings revealed that the mechanical properties of the processed aligners significantly decreased over time, while the unprocessed material consistently showed superior properties, indicating that the manufacturing and aging processes negatively impact aligner performance.
