코멘트

  • The patient had a class II due to mandibular retraction
  • As the patient is an adult, the case became surgical.
  • In orthodontic treatment, I performed IPR on lower incisors to align and gain normal overjet to expand the mandible
  • In addition, the impact on the maxilla, made us gain more overjet to expand the mandible and rotate counterclockwise
  • I used Class III elastic on both sides to make lower incisor movements more predictable
