O deslocamento de dentes ou raízes para o interior do seio maxilar é um acidente associado a forças excessivas durante movimentos de luxação para uma extração dentária, principalmente quando esta cavidade aérea se encontra em íntimo contato com o elemento dental e está pneumatizada. Complicações podem ocorrer no pós-operatório devido à presença de um corpo estranho no seio maxilar, sendo a sinusite maxilar a mais prevalente. O objetivo deste trabalho é reportar o caso de um terceiro molar superior deslocado para o interior do seio maxilar. Palavras-chave: Seio maxilar. Corpo estranho. Cirurgia.
Le Fort I maxillary osteotomy is a surgical procedure indicated for patients with changes in bone growth, deformities in the face and changes in the bite. Due to the great acceptance of the down fracture, it has been increasingly used for such purposes. A better access allowed by this technique, where it is possible to move the segment in several directions, anterior, posterior and inferior, promotes significant changes from soft tissues to bone and neurovascular structures. The objective of this work is to present the recovery of sensitivity in patients who underwent Le Fort I maxillary osteotomy. It is a literature review, with articles in English, with the descriptors: Maxillary Nerve; Paresthesia; Orthognathic Surgery, searched in the database: PubMed. 22 articles were found, after analyzing only 14 articles that met the inclusion and exclusion criteria. Lesions of the sensory nerve by the oral cavity have been reported after orthognathic surgery. It was observed that the sensitivities of the oral mucosa below the vestibular incision was decreased during the first 2 months, but gradually returned and was restored after 6 months. The sensitivity of the upper teeth respond negatively to the pulp electrical test in 2 months postoperatively, but after 6 months 90% of the teeth show a positive response. It is known that complications and changes in sensation are inevitable after orthognathics, however, over time, this condition resolves spontaneously, although the results may change due to the physiological and anatomical variations of each patient.
A coronectomia ou odontectomia parcial intencional é uma alternativa cirúrgica para a exodontia de terceiros molares inferiores que apresentam algum grau de proximidade com o canal mandibular (CM). Esta técnica consiste na remoção da porção coronária do dente incluso e parte de suas raízes permanecem intactas dentro do alvéolo dentário. Deste modo pode-se reduzir as chances de lesão ao feixe vásculo-nervoso alveolar inferior. O objetivo deste trabalho é relatar o caso de uma paciente que se submeteu a coronectomia de um terceiro molar inferior impactado, que apresentava suas raízes em íntima relação de contato com o CM.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
