Abstract
Anterior crossbite is relatively a common presentation in the mixed dentition stage. If left untreated, it can lead to a host of problems and may complicate future orthodontic treatment. One of the major difficulties in performing anterior crossbite correction in young children is treatment compliance. In most cases, poor compliance is due to the unacceptability of the removable appliance used. This article describes three cases of successful correction of anterior crossbite of patients in mixed dentition using short-span wire-fixed orthodontic appliances. This sectional appliance provides an alternative method of correcting anterior crossbite of dental origin and offers many advantages compared to the use of removable appliances.
Highlights
Anterior crossbite is defined as an abnormal reversed relationship of a tooth or teeth to the opposing teeth in the buccolingual or labiolingual direction, and it is known as reverse articulation [1]. e prevalence of anterior crossbite ranges from 4.5% to 9.5% based on the respective studied populations [2,3,4,5]
Anterior crossbite is a common presentation in children during the early mixed dentition stage, and a majority of the cases are of dental origin [21]
Possible causes of dentally related anterior crossbite are the presence of supernumerary tooth/teeth, odontomas, trauma to the primary predecessor, ectopic position of permanent tooth germ, retained primary predecessor, anomalies in tooth shape and size, arch length inadequacy, and upper lip biting habit [7, 13, 14]. ese dentally related factors are responsible for deflection of the normal eruption path of the permanent successor tooth/teeth
Summary
Anterior crossbite is defined as an abnormal reversed relationship of a tooth or teeth to the opposing teeth in the buccolingual or labiolingual direction, and it is known as reverse articulation [1]. e prevalence of anterior crossbite ranges from 4.5% to 9.5% based on the respective studied populations [2,3,4,5]. A simple method such as tongue blade can be used in the early stages of anterior crossbite development as the tooth/teeth are erupting. Is article highlights three cases of successful correction of anterior crossbite using simple short-span wire-fixed orthodontic appliances.
