Clinical case
Short-term
Not treatable in short-term
Mid-term
Steps : 11
Treatment period : approx. 22 weeks
Analysis : maxillary lateral incisor cross bite
Treatment
After creating a space for alignment while resolving anterior crowding,
#12/#22 I made the teeth jump.
Afterwards, the central incisor that protruded anteriorly was aligned while retraction,
and the setup was completed with overall retraction.
Long-term
Steps : 17
Treatment period : approx. 34 weeks
Analysis : anterior cross bite
Treatment
Because the treatment is quite complex, we did not design all the steps at once, but
several new impressions and model scans.
We first setup to eliminate crowding through IPR and expansion.
During the maxillary expansion, the mandibular intrusion and + torque were performed
to avoid occlusal interference with the goal of lateral incisor jumping.
During retraction, #12/#22 extrusion was performed to avoid open bite.
