Abstract: Anterior crossbite or reverse overjet is the term used to describe an abnormal labiolingual relationship between one or more maxillary and mandibular incisor teeth. This may involve just a single tooth or up to all the upper incisors. Interceptive treatment is usually carried out in order to reduce the severity of this developing malocclusion in the mixed dentition. Different techniques have been used to correct anterior crossbite with variable effectiveness. This case report demonstrates a simple and cost-effective method for the correction of severe segmental anterior crossbite with a removable, lower Catalan’s appliance initially and upper posterior biteplane with a z-spring later.

Clinical relevance: Anterior crossbite correction in the early mixed dentition is highly recommended as this kind of malocclusion does not diminish with age and could lead to further complications. Removable appliances are safe, cost-effective, rapid and an easy alternative for the treatment of crossbite cases requiring simple tipping, in contrast to a fixed appliance, which can be use in more complex conditions, is expensive, unaesthetic, difficult to maintain and needs a posterior bite platform incorporated.
