Extract the over-retained 75, infraoccluded 85, impacted 45 and
15,25 in conjunction with comprehensive orthodontic fixed appliance
treatment.
- Rapid maxillary expansion (RME) to address the maxillary transverse
deficiency and correct the LHS posterior lingual crossbite
- Removing the 15,25 can be justified to balance the removal of the
75,85
- Ideally, TAD-assisted space closure should be performed in both the
maxillary and mandibular arches for effective molar mesialisation and
to avoid any significant incisor retraction (as the current lip
position and incisor angulations are deemed to be harmonious and
favourable)
- Review the unerupted maxillary and mandibular third molars until their
expected eventual clinical eruption
