Justification: Canines represent corners in the dental arch, and are important features in facial esthetics, as they support the upper lip, wing of the nose, and influence the nasolabial fold and the appearance of facial aging. In the laterality movements, the canines guidance coordinate the opening and closing of the teeth, saving the TMJ from sudden movements. Discussion: As a result of the lack of eruption or the inadequate positioning of the maxillary canine, the loss of the laterality guide may occur, which will then occur in the maxillary lateral incisor, inducing lesions of “occlusal trauma”, such as inflammatory root resorption. Likewise, without well positioned canines, there may be premature aging and change in facial esthetics. Conclusion: In order to avoid problems with eruption and positioning of the maxillary canines, early diagnosis is made by analyzing their position and their relationship with the other teeth, and in the three-dimensional context of the maxilla, bet...

Perfuração do esmalte para o tracionamento de caninos: vantagens, desvantagens, descrição da técnica cirúrgica e biomecânica2011 •
INTRODUÇÃO: a tração de dentes não irrompidos sempre foi considerada um procedimento de risco na prática ortodôntica. Com essa perspectiva, é indispensável a busca por eficiência nos procedimentos adotados para esse mister, o que justifica a proposta do presente artigo. Ao perfurar, vazamos uma estrutura natural, cuja restauração com material artificial é uma ação que está no escopo da área de maior evolução da Odontologia, não havendo justificativa para se evocar procedimentos de maior risco, como a colagem ou laçada com fios. OBJETIVO: este artigo objetiva apresentar protocolos para a Perfuração do Esmalte para o Tracionamento de Caninos (PETC), especificamente os caninos superiores, mais acometidos pelas anomalias de posicionamento, também denominadas disgenesias. Serão abordadas as vantagens e desvantagens da PETC em relação à Colagem de Acessório para o Tracionamento de Caninos (CATC), apresentando-se casos clínicos de diferentes níveis de complexidade, tendo como ponto de part...

Orthodontic traction of impacted canines: Concepts and clinical application2019 •
Orthodontic traction of impacted canines stands as a major challenge for Orthodontics. It is a relatively frequent clinical complaint which management, more often than not, requires a multidisciplinary approach. Surgical exposure of the impacted canine, and the complex orthodontic mechanics applied to align the tooth back into the arch, may frequently lead to complications involving supporting tissues, not to mention the long treatment time and high costs imposed to patients. In face of that, it is worth highlighting the relevance of early diagnosis as to intervene efficiently and as soon as possible. This paper presents a review of the main concepts involving prevalence, etiology and classification of impacted canines, and describes the different clinical management options that would help solve the problem. It illustrates the topic by presenting a treatment delivered to a 13 year 7 months old male patient, suffering from a Class II, division 2, left subdivision, malocclusion, asso...

Orthodontic treatment with passive eruption and mesialization of semi-impacted mandibular third molar in an adult with multiple dental lossesObjective: This article describes the orthodontic treatment performed on an adult patient with multiple dental losses. Case report: A female patient, 20 years and 4 months old, presented with the following conditions: absence of teeth #26, #35, #36 and #46; semi-impacted tooth #48; inclined molars adjacent to an edentulous space; canines and premolars in a Class II relationship; a convex profile; biprotrusion; and forced lip sealing. Results: Space in the region of tooth #26 was closed, as well the space of tooth #46; tooth #48 erupted and followed mesial movement passively; space of the region of tooth #35 was maintained for the placement of a dental implant; uprighting of tooth #37 was obtained. Aesthetic and functional goals of the treatment were achieved. Results remained stable 10 years after the end of the treatment. Conclusion: The modified helical loop could be effectively used in orthodontic mechanics to close edentulous spaces. Passive semi-impacted mandibular third molar ...

Tooth transposition: a multidisciplinary approachTooth transposition is one of the most difficult dental anomalies to treat in the dental clinic. Several factors must be taken into account with a view of making the best decision. The aim of this study was to discuss treatment modalities for tooth transposition, their advantages and disadvantages. Additionally, it aims at presenting a clinical case of transposition between canine and lateral incisor in the upper quadrant on the right side. The treatment of choice was extraction of one transposed tooth. A multidisciplinary approach involving Orthodontics, Cosmetic Dentistry, and Periodontology was necessary to allow proper esthetic and functional outcomes to be achieved.

Finite element method (FEM) analysis of the force systems produced by asymmetric inner headgear bows2011 •
BACKGROUND: Extra-oral traction appliances were introduced more than a century ago and continue to be used to produce orthopaedic and/or dental changes in the maxilla. While force systems produced by asymmetric outer bows have been studied extensively, the force systems produced by asymmetric inner bows have been overlooked.AIM: To analyse the forces acting on the maxillary first molars: when the size of one bayonet bend is increased; when the point of application of the distalising force on the inner bow is moved to one side; when one molar is displaced palatally.METHODS: Four FEM models of cervical headgear attached to maxillary first molars were designed in SolidWorks 2010 and transferred to an ANSYS Workbench Ver. 12.1. Model 1, each molar was 23 mm from the midpalatal line and the inner bow was symmetrical; Model 2, the left molar was displaced 4 mm towards the midpalatal line and the inner bow was symmetrical; Model 3, the molars were equidistant (23 mm) from the midpalatal line, but the left molar was engaged by a 2 mm larger bayonet bend; Model 4, the molars were equidistant (23 mm) from the midpalatal line but the join between the inner and outer bows was displaced 2 mm towards the left molar. In all FEM models, a 2N force was applied to the inner bow at the join between inner and outer bows and the energy transmitted to the teeth and the von Mises stresses on the molar PDLs were assessed.RESULTS: There were marked differences in the strain energy on the teeth and the von Mises stresses on their PDLs. A 14 to 20 per cent increase in energy and force was produced on the tooth closer to the symmetric plane of the headgear. In addition, the increase in energy produced a 30 to 62 per cent increase in the von Mises stresses within the PDLs.CONCLUSION: Small asymmetries in molar position, the size of a bayonet bend and the point of application of a force on an inner bow resulted in asymmetrical forces on the molars. These forces were higher on the molar closer to the symmetric plane of the headgear.

Severe gingival recession caused by traumatic occlusion and mucogingival stress: a case report2008 •
Gingival recession is displacement of the soft tissue margin apically leading to root surface exposure. Tooth malpositions, high muscle attachment, frenal pull have been associated with gingival tissue recession. Occlusal trauma is defined as injury resulting in tissue changes within the attachment apparatus as a result of occlusal forces. Trauma from occlusion may cause a shift in tooth position and the direction of the movement depends on the occlusal force. We present the clinical and radiological findings and the limitation of periodontal treatment of a severe gingival recession in a case with traumatic occlusion. A 16 years old male, systemically healthy and non-smoking patient presented to our clinic with severe gingival recession of mandibular canines and incisors. Clinical evaluation revealed extensive gingival recession on the vestibules of mandibular anterior segment. Patient has an Angle class III malocclusion and deep bite. To maintain the teeth until orthodontic therapy...

BACKGROUND: Teeth impaction has become a common problem faced by orthodontic clinicians with the greatest incidence reported among third molars and maxillary canines. The great challenge lies in successfully treating these cases without deleteriously affecting the impacted as well as adjacent teeth while achieving acceptable functional and esthetic results. Several etiological factors have been associated with impactions including the presence of an odontome which is an asymptomatic odontogenic hamartomatous lesion. CASE REPORT: This article presents a detailed orthodontic assessment and treatment of a 16 years old female having impacted right maxillary lateral incisor and canine caused by complex odontome. CONCLUSION: Successful orthodontic treatment of multiple impactions can be achieved with minimal side effects even when odontomes are associated, through 3D radiographic examination, detailed evaluation as well as proper biomechanical control.
