Comments

  • The Invisalign aligners was a good choice for space closure and alignment, but the vertical relationship was at risk
  • At the end of the initial treatment, we could see an overbite
  • We used one refinement to intrude the incisors and simultaneous overcorrection of anterior
  • Power ridges were used to control the inclination of the upper central incisors and lower incisors
  • After the refinement, all treatment goals were achieved and the patient gained a beautiful profile
