[Aesthetic rehabilitation of a case of maxillary fibrous dysplasia in a child].

Fibrous dysplasia (FD) is a rare, congenital, benign bone disorder in which healthy bone tissue is replaced by abnormal scar-like (fibrous) connective tissue. The lesions may affect one or more bones, including the jawbones. A 13-year-old girl visited the dentist for failed eruption of her left maxillary permanent teeth and facial asymmetry. Radiological analysis revealed impactions of the permanent teeth in hypertrophic, hyperdense, weakly trabeculated bone tissue. To restore the aesthetics of the smile, a treatment combining decoronation and bonded restorations was performed. FD enlargement would slow down after puberty, allowing for long-term therapies. But there is no information about implantology in this type of bone lesion. The aesthetic and functional consequences of a maxillary FD should be managed as soon as possible. Treatment involves a multidisciplinary team and follow-up care into adulthood.
