Comparing the Impact of Rubber Bands on Teeth Straightening with Clear Aligners Versus Traditional Braces: a Clinical Study

Aim: To analyze the inclination of lower incisors in patients with Class II malocclusion treated with elastics and clear aligners compared to a group wearing the same elastics and fixed appliance. A sample of 40 patients (19M and 21F), mean age 15.4±1.8 years, was randomly divided in two groups: Clear aligner group (CA), Fixed appliance group (FA). The subjects were selected according to inclusion criteria: full permanent dentition (excluding third molars), Class II molar relationship (2,5-4 mm), no history of orthodontic treatment.
