Orthodontic treatment of anterior crossbite using Frankel appliance for a patient with intellectual disability

Abstract

In children with disabilities, malocclulsion prevalence is relatively high. Malocclusion negatively affects these patients and reduces quality of life. However, it is often difficult to perform ideal orthodontic treatment due to lack of cooperation. Therefore, simple and feasible plans should be established for patients with disabilities. This case report is on treatment of anterior crossbite using Frankel appliance in a disabled patient. A 6-year-old patient with intellectual disability visited the Department of Pdeiatric Dentistry, Yonsei University Dental Hospitalwith the chief complaint of anterior crossbite. Upon oral examination, The patient was diagnosed with pseudo class III malocclusion. Considering the patient’s medical history and degree of cooperation, it was decided to use the Frankel appliance III, with a focus on resolving the anterior crossbite. The patient was well adapted to the appliance, and the anterior crossbite resolved two months after the start of treatment. Since then, it has been maintained without relapse. The patient and their caregivers were very satisfied with the treatment results.
