Cephalometric evaluation of adult anterior open bite non-extraction treatment with Invisalign
Conclusions: The Invisalign system is a viable therapeutic modality for non-extraction treatment of adult anterior mild open bites. Bite closure was mainly achieved by a combination of counterclockwise rotation of the mandibular plane, lower molar intrusion and lower incisor extrusion.RESUMO Objetivo: o objetivo desse estudo foi realizar uma avalia ção cefalométrica dos efeitos verticais do tratamento sem extração de mordidas abertas anteriores em adultos com o uso de alinhadores (sistema Invisalign, Align Technology, Santa Clara, CA, EUA). Métodos: foram analisados cefalogramas laterais de 30 pacientes adultos co...

Dehiscences and fenestrations: methodological care necessary to avoid errors in diagnosis and measurement
ABSTRACT The low prevalence of gingival recessions observed in orthodontic clinical practice may be assigned to the fact that in studies in which dehiscences and bone fenestrations are described as frequent, they were diagnosed based on: 1) dry skull studies; 2) areas with periosteal reflection together with flap; and 3) imaging techniques with low sensitivity to detect these defects, which have a delicate structure and function. In areas of pseudo-dehiscences and fenestrations, the periosteum and the alveolar cortical bone are very thin; also, they either have been removed during preparation of the dry specimens in the ar...

Sustainability in Orthodontics: what can we do to save our planet?
ABSTRACT The sustainability of the natural resources of our planet is a topic for worldwide debate. Mankind, during its evolution as a species, has not been greatly concerned about conserving the environment in which we live. Nowadays we are reaping the fruits of this neglect. Climatic changes and storms are good examples of this. We, humans, must re-think our attitudes in order to leave the planet in a healthy state to be used by our descendants. But thinking of orthodontics, what can we do as orthodontists? From this perspective, the authors of the present study aimed, in a clear and objective manner, to present simple a...

Class II Division 2 subdivision left malocclusion associated with anterior deep overbite in an adult patient with temporomandibular disorder
ABSTRACT The orthodontic treatment of patients with chief complaint of temporomandibular disorders (TMD) presents doubtful prognosis, due to the poor correlation between malocclusions and TMDs. The present case report describes the treatment of an adult patient with Angle Class II Division 2 subdivision left malocclusion associated with anterior deep overbite and TMD. This case was presented to the Brazilian Board of Orthodontics and Dentofacial Orthopedics (BBO), as part of the requirements to obtain the title of BBO Diplomate.RESUMO O tratamento ortod ôntico de pacientes com queixa principal de disfunção nas articulaÃ...

Taking advantage of an unerupted third molar: a case report
Conclusion: When a mandibular second permanent molar shows an atypical root resorption, an impacted third molar can effectively substitute the tooth by using an appropriate orthodontic-surgical approach.RESUMO Introdu ção: o objetivo do tratamento odontológico cirúrgico é deslocar os dentes para a posição correta na arcada dentária. Objetivo: relatar um caso clÃnico de aproveitamento de terceiro molar não irrompido. Histórico do caso: paciente do sexo masculino, com 18 anos de idade, foi encaminhad o, pelo dentista responsável pelo caso, para avaliação dos terceiros molares. Ao exame clÃnico, os terceir...

Condylectomy and “surgery first” approach: An expedited treatment for condylar hyperplasia in a patient with facial asymmetry
ABSTRACT Condylar Hyperplasia (CH) is a self-limiting pathology condition that produces severe facial deformity at the expense of mandibular asymmetry. In this case report a 15-year-old female patient was diagnosed with Unilateral Condylar Hiperplasia (UCH) by mean of single-photon emission computed tomography (SPECT) and histological study. A high condylectomy in the right condyle was performed to stop the active status of the hyperplasia. A month after condylectomy, orthognathic jaw impaction and asymmetric mandibular setback surgery was performed with the Surgery First Approach (SFA). After 10 days, orthodontic appointm...

Bacterial adhesion on conventional and self-ligating metallic brackets after surface treatment with plasma-polymerized hexamethyldisiloxane
Conclusion: Plasma-polymerized film deposition was only effective on reducing surface roughness and bacterial adhesion in conventional brackets. It was also noted that conventional brackets showed lower biofilm adhesion than self-ligating brackets despite the absence of film.RESUMO Introdu ção: a deposição de filme de polÃmero a plasma foi criada para modificar as propriedades de superfÃcie dos braquetes ortodônticos metálicos, com o intuito de inibir a adesão bacteriana. Métodos: filmes finos de polÃmero de hexametildisiloxano (HMDSO) foram depositados em braquetes ortod ônticos de aço inoxidável convenci...

Skeletal effects of RME in the transverse and vertical dimensions of the nasal cavity in mouth-breathing growing children
Conclusions: No significant differences were associated regarding sex. The RME produced significant width increases in the maxilla and nasal cavity, which are important for treatment stability, improving respiratory function and craniofacial development.RESUMO Introdu ção: a constrição maxilar é uma alteração dentoesquelética relacionada à diminuição transversal da arcada superior, que pode correlacionar-se com problemas respiratórios. O tratamento nos pacientes em crescimento inclui a expansão rápida da maxila (ERM). A correção precoce resulta e m maiores alterações esqueléticas e estabilidade dos res...
