评论

  • This is a patient with a large OJ and with canine class II, so I choose MA to let the mandible advance and achieve class I occlusion.
  • After 7 months MA, some posterior open bite appeared. Because patient's eruption potential for the posterior teeth, we just did some posterior extrusion and anterior intrusion to get a stable occlusion.
