What does this research mean for the field?

A combined orthodontic approach utilizing a bonded Hyrax expander, premolar and third molar extractions, and skeletal anchorage is effective for managing complex Class I malocclusion with bilateral posterior crossbite and a vertical growth pattern. Novelty: ClaimNovelty.INCREMENTAL. Consensus alignment: ConsensusAlignment.NEUTRAL.

What question did this study set out to answer?

Implication

Case report demonstrates successful orthodontic correction in an adolescent with crossbite and vertical growth pattern, indicating the efficacy of maxillary expansion combined with skeletal anchorage.

Key Points

To describe the orthodontic management of a Class I malocclusion with severe crowding, bilateral posterior crossbite, and an exaggerated vertical growth pattern.
Treated a 14-year-old female presenting with 9 mm upper and 5 mm lower dental crowding and a reduced 29 mm intermolar width using a bonded Hyrax expander on a semi-rapid protocol.
Extracted all four second premolars for alignment and leveling, followed by extraction of all third molars.
Utilized 0.022" × 0.028" MBT pre-adjusted edgewise appliances alongside skeletal anchorage to achieve vertical control.
Corrected the bilateral posterior crossbite and expanded the constricted maxillary arch.
Resolved anterior crossbite, canine ectopia, and upper and lower dental crowding while establishing optimal overjet and overbite.
