评论

  • G6 system is adopted to ensure maximum anchorage.
  •  Posterior teeth were kept basically immovable, and all the tooth extraction Spaces were used for adduction of the anterior teeth
  • Wisdom teeth were removed before the fine-tuning stage, so that the opening and closing of the back teeth could be solved quickly
  • Two types of traction were used in the fine-tuning phase to ensure that a neutral occlusion of the posterior teeth could be achieved
