Retention period in children with crossbite

Abstract

Relevance. Crossbite is a deformation of the dentoskeletal system in the horizontal (transversal) plane, and it results from a discrepancy between the width of the upper and lower dental arches in the anterior or posterior dentition.Crossbite can arise as an isolated condition, and then it is an independent de-formation of the dentoskeletal system. In some cases, a crossbite is combined with a wrong arch-to-arch relationship in the sagittal and vertical planes.The aim was to analyze the duration of the retention period in children with crossbite after the orthodontic treatment.Materials and methods. We orthodontically treated 18 children with crossbite aged 7 to 18 years. All patients were divided into 2 groups. Group 1 included 14 children from 7 to 14 years old with unilateral crossbite (right-sided – 6, left-sided – 8). Group 2 included 4 children from 9 to 18 years old with bilateral crossbite. All 18 children had a buccal crossbite. All patients underwent orthodontic treatment with removable and fixed orthodontic appliances.Results. The retention period after the orthodontic treatment of crossbite lasted 6-9 months.Conclusions. The analysis demonstrated that the retention period after the orthodontic treatment in children with crossbite averaged 6-9 months. The design characteristics of the or-thodontic appliances did not affect the duration of the retention period in children with crossbite.
