Comparative microscopic analysis of plastic dispersion from 3D-printed and thermoformed orthodontic aligners
DPA generated larger and more numerous plastic particles compared to TFA, though grain-size characterization was challenging due to particle aggregation. This suggests that the manufacturing process and materials used in DPA could impact the creation of MPs and NPs during simulated mastication, highlighting a potential area for process optimization.
