Summary

Posterior crossbite is a common clinical condition often associated with transverse maxillary deficiency and functional mandibular shift. This frequent malocclusion is not self-correcting and can lead to the development of craniofacial asymmetries and mandibular dysfunction.

The aim of the current study was to evaluate maxillary and mandibular arch widths' response to RME when it is anchored to the upper second deciduous molars or to the upper first permanent molars and to create a decision-making protocol for RME therapy in mixed-dentition patients.

Conditions

  • Posterior Crossbite

Interventions

PROCEDURE

Rapid maxillary expansion

When rapid maxillary expander was in-situ, patients waited 7 days before starting the screw activation of one quarter turn a day (0.22 mm) until overcorrection. Expansion was considered adequate when the occlusal surface of the first maxillary palatal cusp contacted the occlusal surface of the mandibular first molar facial cusp. When was achieved, rapid maxillary expander stayed in place for 10 months.
