The development of digital technology contributes to the diagnosis, treatment and therapeutic outcome analysis in orthodontics. The present case describes a female patient with a protrusive profile who sought clear aligners orthodontic treatment. She was skeletal Class II with maxillary protrusion and mandibular retrusion. The extraction of two maxillary first premolars and interproximal reduction of the mandibular anterior teeth were used to correct the situation. An incisors retraction was performed to improve the horizontal overlap. The anterior teeth were lowered to improve the patient's vertical overlap. After 28 months of orthodontic treatment, the patient convex facial profile was improved, and a normal horizontal overlap and vertical overlap were achieved.
