Management of Anterior Single Tooth Crossbite Using Removable Posterior Teeth Bite Plane Along With Z-Spring: A Case Report

Abstract

Anterior crossbite is defined as a malocclusion characterized by the anterior maxillary teeth lingual position compared to mandibular anterior teeth. The prevalence of anterior crossbite that has been reported in the mixed dentition stage varies between 1.6 percent and 7.9 percent. Anterior crossbite cases should be treated by emergency intervention in the early period to prevent the consequences of malaligned teeth and their effect on the normal overall growth and development of the child. Patient compliance in such type of treatment intervention is of utmost importance. This case report presents the correction of single tooth crossbite with the removable posterior bite     plane along with Z-spring. Various other treatment modalities have been also proposed to correct an anterior dental crossbite, such as tongue blades, reversed stainless steel crowns, fixed acrylic planes, bonded resin-composite slopes, and removable acrylic appliances incorporating finger springs. This treatment modality is possible in the early stages of developing malocclusion. Children with untreated anterior crossbite could develop complications such as gingiva recession, TMJ dysfunction, and worsening of mandibular displacement. As self-correction is rare in these alterations, early interception is recommended to allow normal occlusion and  facial development.
