OBJETIVO: O objetivo do presente artigo é reportar um caso de Classe III subdivisão com mordida aberta anterior esquelética. CASO CLÍNICO: O caso foi tratado usando a técnica MEAW para mudar a inclinação do plano oclusal posterior, que se encontrava aplainado. RESULTADOS: Observou-se a correção da Classe III subdivisão, bem como da mordida aberta anterior, por meio de compensação dentária. CONCLUSÃO: O tratamento se mostrou estável após dois anos da correção da Classe III subdivisão e da mordida aberta esquelética.

ABSTRACT
Orthodontic Science and Practice, 2020
The spatial position of the cranio-maxillary-mandibular complex is related to the natural positio... more The spatial position of the cranio-maxillary-mandibular complex is related to the natural position of the head, which is not always easily obtained due to vicious and unconscious postural compensation. The cross-laser allows the fixation of certain face parameters, which lead to natural and adequate positioning of the head for lateral teleradiography in conjunction with facial analysis. The severity of Pattern III skeletal discrepancy is masked by soft tissues, and is best investigated and quantified with the patient in smiling profile, relative to true vertical, and can be compared with cephalometric analysis. The treatment of this discrepancy is directly related to its severity. This article aims to demonstrate the relevance of the cross-laser as an auxiliary tool in the analysis of the facial severity of patients Pattern III. Three clinical cases with different severities for Pattern III and their respective treatment approaches are presented.

METHODS: Twenty-five adult male Wistar rats, divided into two groups, had stainless steel springs installed on left maxillary first molar. The molars were moved for 18 days, and after removing the springs, were applied by oral gavage, 5mg/kg of simvastatin in the experimental group for 20 days. Tooth relapse was assessed with a micro CT scanner, and the images chosen through the Data Viewer software 1.5.0.0 had their measurement guides made and checked by the software Image ProR plus 5.1, and compared by MannWhitney test. After rats were sacrificed, bone mineral density was evaluated by micro CT through the software CT Analyzer 1.13 and compared by independent T-test, as well as by Spearman correlation test. RESULTS: Relapse and bone mineral density (BMD) was lower in the experimental group than...

Notavelmente, a RRIE e tida como um custo biologico do tratamento ortodontico, e de certa maneira inevitavel. A aplicacao da forca ortodontica desencadeia o processo devido a liberacao de mediadores locais da inflamacao, e so cessa quando esta mesma forca e de toda dissipada ou cessada. A sua etiologia esta relacionada com a necrose da camada cementoblastica que reveste a dentina, que contem um grande numero de antigenos sequestrados, e os esconde do sistema imunologico desencadeador do processo reabsortivo. O seu diagnostico e geralmente tardio, somente atraves de radiografias periapicais, quando o processo ja ha muito se iniciou. Alguns estudos indicam que patologias dentarias sao acompanhadas pela liberacao de proteinas em fluidos extracelulares como o fluido crevicu...

It also aims at conducting a review on the current candidates for protein markers of this pathology, all of which may be used to prevent the disease. Gingival crevicular fluid was collected from two groups of 60 patients each, with and without external root resorption. Samples were extracted by means of various methods of protein extraction. SDS-PAGE gels were used to assess the quality of the method which was subsequently tested during isoelectric focusing of 2-DE gels taken from samples of patients with and without the disease. Milli-Q ultrapure ice cold water, without precipitation for gingival crevicular fluid protein extraction, proved the method with greatest sharpness to detect protein bands. Additionally, it allowed two-dimensional electrophoresis to be performed. The new protein extraction protocol does not interfere in isoeletric focus...

To evaluate the effect of chemically modified tetracycline-3 (CMT-3) and simvastatin on tooth relapse after orthodontic movement in rats using a novel analysis method employing high-resolution micro-CT (Micro-CT) images. In addition, the correlation between bone density and orthodontic relapse was also evaluated for each experimental group. Methods. Forty adult male Wistar rats had stainless steel springs installed on their left upper first molars in order to generate tooth movement for 18 days. After this initial period, the animals were divided into three groups: (1) 30 mg/kg of CMT-3; (2) 5 mg/kg of simvastatin; and (3) 0.5% carboxymethylcellulose, and each group was treated for 20 days. Micro-CT images were analyzed (conventional method and 3D reconstruction) on the 7th and 18th days following spring fixation and finally, 20 days after treatment either with CMT-3 or simvastatin (38th day). Bone mineral density (BMD) of the mesial and distal roots of the upper first mo...

The aim of this study is to discuss the immediate and mediate risks of removing the Bichat ball, as well as describing a clinical study in which this surgical procedure resulted in lesions of the parotid gland and buccal artery, which was confirmed via nuclear magnetic resonance. The facial lesions were remedied via exploratory surgery by opening a new orifice of the glandular duct in the buccal cavity followed by drainage and compressive surgical bandages.

Many clinical variations of the Haas appliance were designed according to different malocclusion presented in the deciduous dentition, mixed and permanent. However, no such change meets the need for simultaneous correction of malocclusion sagittal, vertical and transverse, which resulted in the emergence of the Haas expander 3-D proposed by the Como citar este artigo: Franco EJ, Vieira GM, Guimarães Júnior CH.

Os arcos multifuncionais (Arco de intrusão de nitinol CIA ® e arco de retração Mushroom Loop ® ) foram idealizados no intuito de simplificar o atendimento clínico do ortodontista que, municiado de recursos diagnósticos apropriados e sólidos, os utiliza como uma ótima alternativa entre as disponíveis para a resolução dos problemas e expectativas dos pacientes. Com o presente artigo procurou-se demonstrar que os arcos de intrusão de nitinol (CIA ® ) e o arco de retração Mushroom Loop ® são ferramentas poderosas no tratamento de pacientes com extrações dentárias que requerem um controle de ancoragem mais apropriado, bem como uma retração mais eficaz.
