In children with Class III malocclusion, it is important to identify whether the etiology is functional, dental, skeletal. FR-III developed by Rolf Frankel in 1970, has been used during deciduous, mixed, and early permanent dentition to correct class III malocclusion characterized by maxillary skeletal retrusion. According Frankel, the vestibular shields and upper labial pads act to counteract the forces of the surrounding musculature that restrict forward maxillary development and cause a retrusion in maxillary tooth position. This can achieve favorable developments with the basal bone, teeth and alveolar bone. We report FR-III that can be applicated in cases of early mixed dentition with mild maxillary deficiency and deepbite before the eruption of permanent maxillary incisor.

Anterior tooth spacing is observed by pathological tooth movement (PTM), which is common in periodontal patients. And various occlusal factors contribute to PTM, especially in the maxillary anterior region, when there is excessive occlusal force, flaring due to position problem easily occurs. Teeth with loss of periodontal support tissue can secure stability when expanding the support area through intentional splinting, and change the occlusion when restored as a fixed prosthesis. After confirming the stable occlusion through the provisional prosthesis, it can be transferred to the final prosthesis through CAD-CAM. In this case, we present a long-term stable case through accurate diagnosis and treatment of the maxillary anterior teeth that have lost interdental contact.
