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.
