Comments

  • This is a Class I bi-maxillary protrusion case with crossbite
  • The patients chief request was to profile improvement
  • The treatment plan is U4L5 extraction and space closure using maximal anchorage
  • Torque loss of incisors and bite deepening are the main problem during this kind of treatment
  • In this case, we control anterior torque with power ridges and control the bite with precision bite ramp
  • Patient changed her aligner every 7 days with very good compliance
