Comments

  • This is a class III malocclusion case with anterior crossbite and asymmetrical arch form
  • Upper anterior teeth were flared
  • Posteriors were distalized to reshape the arch form, meanwhile removing the anterior interference to relocate the mandible position with Class III elastics
  • After mandible jump, we used Class II elastic to achieve molar and canine class I relationship

  • Maxillary: Fixed/Bonded
  • Mandibular: Fixed/Bonded
