Anterior crossbites are often encountered in orthodontic practice. This malocclusion can be identified at any stage of dental development and may have dental, skeletal, and periodontal repercussions if left untreated. A novel approach for the treatment of an anterior crossbite that does not include any typical orthodontic appliances will be presented. Mandibular deciduous second molars or permanent first molars are built with glass-ionomer cement, thus creating a transient, iatrogenic anterior open bite. Both deciduous and permanent teeth move quickly and predictably to their normal position. This method is patient-friendly as minimal cooperation is needed, especially in deciduous dentition patients. The physiology of the mechanism that corrects crossbites is also discussed.
