Steps : 20
Treatment period : approx. 40 weeks
Analysis : maxillary anterior protrusion including severe protrusion of central incisors
Because the treatment is quite complex, we did not design all the steps at once,
but several new impressions and model scans.
Due to the lack of space for the maxillary, IPR was performed on the premolars,
and the whole dental arch from the premolars to the premolars was expanded and
moved to make the arch from V to U shape, reducing the protrusion of the central incisors.
After creating a space for the central incisors to move, the intrusion was given along with retraction to prevent overbite.
IPR was performed on the mandibular premolars and the arch was expanded to create an environment for improving the long axis of the anterior teeth. At the same time, after adjusting + torque, intrusion, and tip to the anterior teeth, retraction was performed to significantly lower the overbite and create a condition for rearward movement of the maxillary incisors.
