Reason And Periods For Treatment For Posterior Crossbite
Without early treatment Posterior crossbite it can result :
1- facial asymmetry and temporomandibular disorders in adulthood.
2 Furthermore, the muscular hyperactivity on the crossbite side might have an unfavorable influence on craniofacial growth that can lead to craniofacial asymmetry
3- temporomandibular joint (TMJ) dysfunction and deviation from normal facial esthetics.
In normally growing mandible, posterior crossbites should be treated as early as possible Why !? to allow the normal growth and development of the dental arches and the TMJ.

Posterior crossbite management
IN PRIMARY IN MIXED DENTITION
5. •In Primary Dentition
Posterior crossbite in primary dentition is usually as a result of constriction
of the maxillary arch which often results from an active digit or pacifier
habit.
- Determine whether there is an associated mandibular shift.
Mandibular shift
Present Not Present
treatment is implemented to
correct the crossbite
treatment is delayed until the
permanent first molars erupt
If the first permanent molar erupts
into crossbite
If the first permanent molar
erupts normally
Treatment is not indicated until
the permanent premolars erupt
Treatment is initiated (if no
other malocclusion exists)
6. In Mixed Dentition
- Posterior crossbite correction in mixed dentition can be difficult and
confusing.
- The clinician should rely on a well documented database to determine
whether a skeletal/dental correction is necessary.
- And in areas where mandibular shift is present it should be managed
as soon as possible to prevent soft tissue and dental compensation.
