Tratamento ortodôntico de paciente com displasia óssea florida: relato de caso

Abstract

Fibro-osseous lesion is the set of processes that the architecture of normal bone is replaced by a fibrous connective tissue and collagen fibers containing varying amounts of calcified material. The florid osseous dysplasia (DOF) is a fibro-osseous lesion of the jaws with a high prevalence in black women and middle-aged. The DOF is located in both jaws, and when present in only one bone, the posteriorregion of the canine mandible is the most common location, and the periapical region and the epicenter of the lesions contained the alveolar process. The DOF has the edge with well-defined or well-defined sclerotic and fibrous capsule - radiolucent halo - when the lesions are mature, with a density that varies from radiopaque and radiolucent area - until completely mixed radiopaque and radiolucent areas that representprominent bony idiopathic may be present, with oval, circular or irregular, can displace the mandibular canal to a lower position, the maxillary sinus floor to a higher position, causing expansion of the external cortical bone, the lamina dura and periodontal ligament space become is indistinct and the roots of the teeth may have associated with varying degrees ofhypercementosis that can merge with the radiopaque areas of the lesion.The tooth movement is a result of biological events, and studies show that fibroblasts seem to activate neighboring bone cells being responsible for periodontal remodeling of the matrix, but may also be actively involved in regulating the activity of the cells that remodelthe alveolar bone as osteoblasts. And in spite of fibrous dysplasia affecting the proliferation and osteoblastic activity, studies suggest a normal response to the dysplastic bone orthodontic forces and thus the possibility of an orthodontic treatment The aim of this paper is to present a literature review of the orthodontic treatment of patients with DOF and the report of a clinical case related with this situation.
