Introduction: Anterior crossbite is a condition that needs emergency treatment regardless of whether it is dental or
skeletal in 6 - 12 year-old children. A malocclusion can lead to periodontal problems, mobility and even loss of the
tooth due to loss of supporting tissue in the antagonist teeth. A simple removable appliance to prevent this situation
solves the problem.
Case Report: Systemically healthy 8-year-old boy in mixed dentition referred to Inonu University Faculty of
Dentistry with the complaint of non-aesthetic appearance of the upper anterior teeth. In the clinical examination, it
was detected that the upper right central incisor of the patient is in cross-bite and maxilla is narrow. A removable
acrylic appliance with raised occlusion were made including a labiolingual spring for buccal movement of the tooth,
a vestibule arc to control buccal angulation, holder hooks and a slow expansion screw. The expansion screw was
turned three times a week by the patient, the springs were activated by dentist with weekly controls. The ideal dental
relationship of the central incisor and sufficient maxillar expansion were achieved in 1 month.
Discussion: In this case report, the anterior cross bite was treated during the mixed dentition period with a modified
removable appliance. Pediatric dentists and clinicians should be aware of eruption failure and premature contacts
can cause occlusal traumas and periodontal diseases.
Conclusion: To prevent maxillary growth in patients and to prevent permanent periodontal damage in antagonist
teeth, urgent measures should be taken with modified removable appliances.
