Open bite treatment through delicate rotation of occlusal and mandibular planes with clear aligners: A case report

This case report presents a successful treatment of an 18-year-old male patient with skeletal open bite and mild dental crowding using clear aligners. The treatment plan involved a series of approaches: sequentially intruding the posterior teeth, extruding the maxillary anterior teeth, and implementing counterclockwise rotation of the mandibular plane and clockwise rotation of the occlusal plane to achieve desirable functional and esthetic outcomes. This comprehensive strategy resolved the anterior open bite and established Class I canine and molar relationships. After 2 years of treatment with a total of 64 (39 + 25) sets of clear aligners and a 1-year follow-up, all treatment objectives, including the resolution of open bite, proper alignment of teeth, mandibular repositioning, and improvement of lateral profile, were successfully achieved. This case demonstrates the effectiveness and advantages of clear aligners in treating anterior open bite. It not only provides a esthetically appealing and comfortable wearing experience, but also achieves remarkable outcomes in complex cases.
