Unicystic ameloblastoma is an odontogenic tumor that affects mainly young patients and usually involves the posterior region of the mandible. In this article, we report on the case a 12-year-old girl presenting with an 8-month history of facial swelling in her lower right quadrant. Radiographic examination revealed a unilocular radiolucent lesion extending from the body of the mandible through to the angle and ascending ramus. An incisional biopsy was performed, and a diagnosis of luminal unicystic ameloblastoma was made based on clinicopathological features. The lesion was treated in two stages, namely, an initial conservative approach via decompression and subsequent excision. The patient has been followed up for 6 months without clinical and radiographic evidence of recurrence. In conclusion, conservative timely intervention combined with a conservative surgical approach has proven efficacious in the treatment of ameloblastoma in this young patient.
The 3DBOT technique (Three-Dimensional Orthodontic Treatment without Brackets) receives this name for performing movements in the 3 dimensions of the space without the use of brackets and with the help of technology through 3D set up. This technique includes advantages such as absolute control of protrusion / retrusion, control of the arch shape and the planned expansion, control of established vertical and anteroposterior movements. It is imperceptible and comfortable, in addition it is a straight and self-ligating technique that allows sliding when necessary. The objective of this work is to report a clinical case of Class II subdivision, using the 3DBOT technique with skeletal anchorage. The combination of the Versatile Skeletal Anchorage Plate on the palate and the 3DBOT technique proved to be a viable option for Class II malocclusion treatment.
A má oclusão de Classe III, por gerar uma maior repercussão negativa na face dos pacientes, desperta uma procura cada vez maior por tratamentos ortodônticos estéticos. O aparelho lingual surgiu no início dos anos 70 e se tornou uma alternativa bastante viá- vel para realização dos tratamentos ortodônticos estéticos, associados ou não às cirurgias ortognáticas. Com o auxílio dos dispositivos temporários de ancoragem esquelética, o tratamento se torna ainda mais estético e com menores efeitos indesejados. O objetivo deste artigo consiste em relatar uma experiência clínica de tratamento orto-cirúrgico utilizando ortodontia estética com aparelho lingual. O relato de caso clínico trata-se de uma paciente de 29 anos, má oclusão Classe III, dolicofacial, que iniciou o tratamento com aparelho lingual superior e vestibular inferior, combinado à ancoragem esquelética com placa versátil palatina. Na mandíbula, mini-implantes foram utilizados na região retromolar. Após o preparo ortodôntico pré-operatório, a paciente foi encaminhada à cirurgia ortognática, finalizando o caso com alinhadores digitais para melhor refinamento, além de contenções removíveis. Concluiu-se que foi possível corrigir, em tempo hábil, a má oclusão adequadamente, com absoluto controle dos torques, dentro das exigências estéticas da paciente, através de aparelho lingual superior, vestibular inferior, cirurgia ortognática e finalização com poucos alinhadores.
