Correction of an anterior crossbite in mixed dentition: a case report
Anterior crossbite is a situation in which one or more maxillary incisors occlude lingually to their antagonists. It constitutes major esthetic and functional concern during the stages of dental development. Single tooth anterior crossbite is a commonly encountered malocclusion during the development of occlusion in children.The correction of anterior crossbite requires the creation of enough space, to bring the displaced tooth or teeth across the occlusion into proper position.Early treatment in very young children prevents the establishment of maloclusion that can potentially worsen with age.Different techniques have been used to correct anterior crossbite in mixed dentition. In this 8-year-old patient, a rapid maxillary expander with welded arm was used. This therapy combined with tonsillectomy followed by breathing exercises improved respiratory function. It is therefore essential to intervene as early as possible to achieve the anatomical and physiological conditions for optimal of growth.
