Dietary changes in patients with clear aligners compared with fixed orthodontic appliances during the early stages of orthodontic treatment: A systematic review

During the first 6 months, multibracket appliances may affect diet more negatively than clear aligners and this pattern does not seem to be explained by differences in pain. Given the low-to-moderate certainty of evidence and indirect diet assessment using items from broader oral health-related quality of life instruments, these results should be interpreted with caution.
