评论

  • The desired results were achieved by using the Class II Motion in combination with lower aligner anchorage.
  • The lower aligners were maximum anchorage to allow the mandibular movement of the mandibular dentition.
  • By having a completely compliant patient with Class II elastics, the force system was able to drive the wedge and improve the overbite in the initial stages, this decreased the number of refinements and treatment time.
