Comentários

  • We wanted to improve the protruded lateral profile of this patient
  • We extracted all the first premolars and retracted the upper and lower anterior teeth
  • This patient has moderate periodontitis with moderate gingival recession and alveolar bone resorption, which leads to the long clinical crowns
  • Because of this the anchorage control and anterior torque, control is easier than for patients with short clinical crowns
  • G6 optimized attachments are a good solution for first premolar extraction cases and were applied on 3 quadrants (1,2 and 4)
