Comments

  • I wanted to post this case because it demonstrates how wonderful the Invisalign orthodontic system is.
  • This patient had 11mm of crowding in both upper and lower arch.
  • The results were achieved with a combination of IPR, proclination of teeth and expansion of both arches.
  • It was an extremely difficult case to treat.
  • I want this case to set an example so that more people will believe in the Invisalign system
