Commentaires

  • The scissor bite of 1.7 was corrected easily by only the aligner.
  • During leveling the curve of Spee, the buccolingual inclination of lower incisors was improved properly.
  • I think the inclination control of incisors by Invisalign is better than a fixed appliance.
  • After space closure of upper extraction site, the axis of all upper teeth was aligned parallel.
  • I strongly recommend the Invisalign system in case of bi-alveolar protrusion to be treated by extraction of 1st premolars.
