Comentarios

  • In this case, I guided the advancement of the lower jaw through the use of an MA device.
  • During the treatment, I avoided retracting the position of the upper anterior teeth and prevented increasing the torque of central and lateral incisors.
  • Simultaneously, I intruded both the upper and lower anterior teeth to reduce any occlusal interference that could affect the forward movement of the chin.
  • Once the jaw position reached the treatment goal, I cut the wings of the aligner to reduce the side effects of posterior open bite that can result from MA treatment.
