1. With a strong desire for invisible orthodontic treatment, the patient worked well with the orthodontist during the orthodontic treatment process, achieving good results. 2. Two mandibular wisdom teeth were extracted before orthodontic treatment. Implant anchorage was used for intermaxillary traction during treatment. IPR was performed for lower anterior teeth after treatment, to remove black triangles, making occlusion more stable and the facial shape more coordinated.
