Biomechanics of extra-alveolar mini-implants
ABSTRACT It is undeniable that extra-alveolar mini-implants anchorage has revolutionized Orthodontics. Correspondingly, the proper understanding of mini-implants biomechanics allowed to broaden the range of dental movements as never seen before in clinical practice. However, in order to produce better treatments, especially regarding the effects in occlusal plane, it is important to be aware of the numerous possibilities of applying force systems based on skeletal anchorage. Thus, this paper aims to address, by means of clinical cases, the application of biomechanics concepts that are extremely relevant to the proper emplo...

Orthodontic treatment as an adjunct to periodontal therapy
This study discusses the role of orthodontic treatment as an adjunct to the control and treatment of periodontal disease conditions, and describes a clinical case of severe anterior mandibular crowding and periodontal disease followed up for nine years and three months after orthodontic treatment completion. Malocclusion impaired proper dental hygiene, which led to bone loss and development of a periodontal abscess between mandibular canines and lateral incisors. After scaling and root planing, orthodontic treatment was initiated with extraction of the four second premolars, to correct the deficiency detected in cephalomet...

Relationship between skeletal Class II and Class III malocclusions with vertical skeletal pattern
Conclusions: A relationship was found between Class II and Class III malocclusion with the vertical skeletal pattern. There is a tendency toward skeletal compensation with both vertical and sagittal malocclusions.RESUMO Objetivo: o objetivo do presente estudo foi estabelecer a rela ção entre os padrões esqueléticos sagitais e verticais, e avaliar quais variáveis esqueléticas podem influenciar na chance de desenvolver uma má oclusão de Classe II ou de Classe III esquelética. Métodos: foi feito um estudo transversal, cuja amostra incluiu radiografias cefalométricas laterais pré-tratamento de 548 pacientes (325...

Comparison of maxillomandibular asymmetries in adult patients presenting different sagittal jaw relationships
Conclusions: When comparing the three sagittal jaw relationships with the same intensity of asymmetry, most maxillofacial aspects were quite similar. The only difference was found for patients with severe asymmetry, as the individuals with Class II showed greater bilateral difference in the vertical positioning of the gonion, when compared to patients with Class III.RESUMO Objetivo: o presente estudo teve como objetivo analisar, por meio de tomografia computadorizada de feixe c ônico (TCFC), as características esqueléticas maxilomandibulares presentes em adultos com diferentes graus de assimetria mandibular e diferent...

Comparison of the accuracy of virtual and direct bonding of orthodontic accessories
Conclusion: Virtual bonding made it possible to obtain more precise/accurate positioning of the orthodontic accessories. The potential accuracy of this method brings new perspectives to refining the indirect bonding protocols.RESUMO Introdu ção: técnicas convencionais, diretas ou indiretas, de colagem de acessórios ortodônticos falham em obter a posição ideal desses. Objetivo: comparar a acurácia da colagem virtual e da colagem direta de acessórios ortodônticos por vestibular. Métodos: uma configuração virtual única (modelo de manequim com Classe I dentária) serviu como base para a geração do modelo ...

Effect of orthodontic treatment on alveolar bone thickness in adults: a systematic review
Conclusion: On patients undergoing different orthodontic treatment techniques, there was a significant bone thickness reduction, mainly on the palatal side. Clinical relevance: These findings are relevant and have to be considered in diagnosis and planning of tooth movement, in order to prevent the occurrence of dehiscence and fenestration in alveolar bone.RESUMO Objetivo: o objetivo da presente revis ão foi avaliar as mudanças na espessura óssea alveolar após o término do tratamento ortodôntico. Métodos: as bases de dados MEDLINE, EMBASE e LILACS foram consultadas para artigos publicados até julho de 2018, s...

Comparison of shear bond strength of orthodontic brackets bonded with a universal adhesive using different etching methods
Conclusions: The universal adhesive evaluated in the present study demonstrated statistically similar bond strengths to conventional orthodontic adhesive in self-etch mode. The bond strength can be improved by adding an initial acid etching or laser conditioning step, although enamel damage was observed in some cases.RESUMO Objetivo: o objetivo desse estudo foi comparar os efeitos de tr ês métodos de condicionamento do esmalte - condicionamento a laser, autocondicionamento e condicionamento ácido (5, 10 e 15 segundos) - sobre a colagem de braquetes com um adesivo universal. Métodos: oitenta e quatro pré-molares supe...

The mechanism: how dental resorptions occur in ameloblastoma
ABSTRACT Knife-edge or blunt root resorptions characterize ameloblastomas and are pathognomonic for this tumor, because they differentiate ameloblastomas from simple bone cysts, odontogenic keratocysts and nasopalatine duct cysts, which do not lead to resorption of involved teeth. Despite the very high frequency and importance of these characteristics for a differential diagnosis, a microscopic examination should also be conducted before defining the diagnosis and the treatment plan for these cases. This paper describes a six-step hypothesis to explain the mechanism by which ameloblastomas promote the characteristic root r...

Erratum
Conclusion: MADs are a solid treatment option for primary snoring and mild or moderate OSAS. Patients with severe apnea who are non-adherent to CPAP may also be treated with MADs. Maxillomandibular advancement surgery is a safe and very effective treatment option to OSAS.RESUMO Introdu ção: a Síndrome da Apneia e Hipopneia Obstrutiva do Sono (SAOS) é uma doença muito prevalente e que traz importantes consequências para a vida dos seus portadores.

A 3-D evaluation of transverse dentoalveolar changes and maxillary first molar root length after rapid or slow maxillary expansion in children
Conclusions: Maxillary expansion (RME and SME) does not interrupt root formation neither shows first molar apical root resorption in juvenile patients. Although slightly larger in the RME group than SME group, both activation protocols showed similar buccal bone thickness and lingual bone thickness changes, without significant difference; and RME presented similar buccal cortical bone changes to SME.RESUMO Objetivo: o objetivo do presente trabalho foi realizar um estudo cl ínico randomizado comparando os efeitos da expansão rápida da maxila (ERM) e da expansão lenta da maxila (ELM).
