评论

  • This patient was very compliant for Invisalign treatment
  • This is a Class I molar relationship on the right side and Class II molar relationship case on the left side
  • We find that this type of case is hard to treat with conventional fixed appliances, but very easy to be treated with the Invisalign system
  • We used Class II elastics on the left side for the distalization of the upper left posterior teeth and achieve a bilateral Class I dental relationship
  • With the use of the Invisalign system, arch expansion, posterior distalization, and anterior teeth intrusion were achieved easily
