Resistance of PETG Materials on Thermocycling and Brushing

open access: yesDentistry Journal, 2023
The aim was to assess the impact of thermocycling and brushing on the surface roughness and mass of PETG material—the most commonly used for orthodontic retainers. A total of 96 specimens were exposed to thermocycling and brushing with three different kinds of toothbrushes depending on the number and thickness of the bristles.
