1-DEFINITION
Anterior Crossbite
An abnormal relationship of a tooth or teeth to the opposing teeth, in which normal buccolingual or labiolingual relationships are reversed.
Incidence 2% - 4%.

2-ETIOLOGICAL FACTORSAnterior crossbite
1-SkeletalGenetic predispositionEmbryological defective developmentClass III malocclusion mandibular prognathia, Insuffecient maxillary2-DentalLingual eruption path of maxillary anterior teethTrauma to deciduous dentition in which there is displacement of tooth buds Retained deciduous causing lingual eruption of permanent teeth Supernumerary teeth
3-Functionala-HabitsDigital or pacifer sucking habits Oral respirationLow tongue positionStomach sleeping postureTongue trusting
b-Pseudo Class IIIClass I skeletal relationshipInsuffecient 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 maximun intercuspation
