The purpose of this study is to evaluate the biomechanical behaviour of direct-printed and thermoformed aligners in different tooth movements, creating a biomechanical planning protocol based on a stratification of tooth movements according to the degree of predictability.

Predictability for each type of tooth movement in patients with direct-printed aligners compared to a control group in which the movements are performed with thermoformed aligners.
Timeframe: Baseline and when the defined endpoint (crowding resolution, LII=0) is reached, an average of six months.
impact on the effectiveness and predictability of biomechanics auxiliaries compared to a control group in which movements are performed without the use of auxiliaries.
