In this article by Orthofree.com, They Explain about anterior crossbite, its prevalence, etiological factors, management, treatment and some case reports.

Anterior Crossbite

Definition 

An abnormal relationship of a tooth or teeth to the opposing teeth, in which normal buccolingual or labiolingual relationships are reversed.

Prevalence 

The incidence in caucasieans ranges between 2% and 4%.

Etiological Factors

• Skeletal
  •  Genetic predisposition
  •  Embryological defective development
  • Class III malocclusionmandibular prognathia , Insuffecient maxillary

•  Dental
  •  Lingual eruption path of maxillary anterior teeth
  •  Trauma to deciduous dentition in which there is displacement of tooth buds
  •   Retained deciduous causing lingual eruption of permanent teeth
  •   Supernumerary teeth

• Functional
  • Habits
    • Digital or pacifer sucking habits
    • Oral respiration
    • Low tongue position
    • Stomach sleeping posture
    • Tongue trusting
  • Pseudo Class III
    •  Class I skeletal relationship
    •  Insuffecient maxillary overjet and incisor interference
    •  Multi-tooth anterior crossbite may result from a functional shift of the mandible in an effort to avoid anterior interference in centric relation and to achieve maximum inter-cuspation.

Examples

Managment

The period of mixed dentition offers the greatest opportunity for occlusl guidance and interception of malocclusion. Here is a few Management care reports:

Skeletal

• Can be controlled during growth by growth modification appliances, such as: Protracion face masks.

Dental

• Dental and  Removable acrylic appliances,  functional Removable acrylic appliances , with posterior bite
