About this trial
Background: Orthodontic forces induce tissue reactions by triggering perturbations from orthodontic appliances, which lead to the modelling and remodelling of alveolar bone. Despite the growing popularity of 3D-printed aligners, no studies have compared their effects on bone metabolism in comparison with thermoformed aligners. Aim: This study aims to assess bone metabolism in patients undergoing treatment with 3D-printed aligners versus thermoformed aligners.
