Focus on leveling the hidden: managing impacted maxillary canines.

INTRODUCTION: The long pathway that the canines take as they emerge into the maxillary arch makes them vulnerable to disruption during their natural emergence time. The process of planning treatment for impacted maxillary canine (IMC) presents significant challenges, underscoring the need for careful consideration and expertise. OBJECTIVE: The aim of this article was to shed light on these complexities by discussing clinical case studies involving IMC, providing insights into the intricacies of their management. CONCLUSIONS: The management of IMC within orthodontics presents a multifaceted challenge that include the necessity for precise diagnostic processes, prudent use of cone beam computed tomography (CBCT), the strategic selection between open and closed exposure techniques, a in-depth understanding of the specific orthodontic biomechanics involved, and a keen awareness of potential adverse outcomes such as ankylosis, prolonged treatment times, root resorption, and additional complications.

Restorative management of severely ankylosed primary molars.

Severe dentoalveolar ankylosis is an etiological factor for malocclusion. When infraocclusion occurs early, it progresses with time, leading to severe consequences in young children because of compensatory supra-eruption of the antagonist tooth and mesialization of adjacent teeth. Early diagnosis allows for interception of the problem and may prevent orthodontic treatment. The purpose of this manuscript is to report two cases of infraocclusion of primary mandibular second molars that were diagnosed early and were treated with composite resin crowns. The use of indirect composite restorations for ankylosed teeth is a good option for primary teeth with a moderate/ severe degree of ankylosis.

An unusual case of severe primary molar infraocclusion.

Dentoalveolar ankylosis is described as the direct union between root cementum/dentin and alveolar bone. Its etiology is unknown, and conflicting opinions have been presented to explain it. Late detection of ankylosed primary teeth may cause serious problems to the occlusion and generally demands a more complex treatment approach. The purpose of this report is to present an unusual case of severe infraocclusion of the primary maxillary right second molar associated with a posterior crossbite in a 6-year-old child. The initial treatment option was tooth extraction, but the tooth resumed eruption spontaneously. After correction of the posterior crossbite and a 1-year follow-up, the tooth remained in occlusion and the permanent successor was developing without problems. From this unusual outcome, it may be concluded that further investigation of this anomaly of eruption is needed.

Submersão severa de dentes decíduos: diferentes abordagens de acordo com o momento do diagnóstico / Severe submerged deciduous teeth: different approaches in accordance with the time of diagnosis

Introdução: a submersão severa de dentes decíduos, condição em que a superfície oclusal do dente apresenta-se nivelada ou abaixo da margem gengival, é rara e são poucos os casos relatados na literatura. Devida importância deve ser atribuída aos casos de submersão severa a fim de evitar potenciais problemas de desenvolvimento oclusal. Quanto mais precoce o diagnóstico e a intervenção, maior a chance de restabelecimento do desenvolvimento normal da dentição. Objetivo: apresentar dois casos de submersão severa de dentes decíduos com diferentes abordagens cirúrgico-ortodônticas de acordo com o momento do diagnóstico, englobando as possíveis etiologias, diagnóstico e opções de tratamento. Conclusão: a intervenção precoce nos casos de submersão severa de dentes decíduos previne problemas durante o desenvolvimento da dentição.

Introduction: the severe submersion of deciduous teeth, a condition in which the occlusal surface of the tooth presents in the level or below of the gingival margin, is rare and few cases have been reported in the literature. Due importance should be given to cases of severe submersion in order to avoid potential problems of occlusal development. How early diagnosis and intervention should be realized, greater the chance of restoring the normal development of teeth. Objective: to present two cases of severe submerged deciduous teeth with different orthodontic-surgical approaches according to the time of diagnosis, involving the possible etiology, diagnosis and treatment options. Conclusion: early intervention in cases of severe submersion of deciduous teeth prevents problems during the development of the dentition.

Attempted traction of impacted and ankylosed maxillary canines.

The aim of this article is to report the clinical orthodontic treatment of an adult patient with 2 impacted maxillary canines. Traction was applied to the impacted teeth; however, after 7 months, the teeth were found to be ankylosed and were extracted. The extraction spaces were closed by moving the posterior teeth mesially with mini-implant anchorage. The results were satisfactory, with the premolars in the functional position of the canines.

Open bite: diagnosis, treatment and stability.

Open bite has fascinated Orthodontics due to the difficulties regarding its treatment and maintenance of results. This anomaly has distinct characteristics that, in addition to the complexity of multiple etiological factors, have aesthetic and functional consequences. Within this etiological context, several types of mechanics have been used in open bite treatment, such as palatal crib, orthopedic forces, occlusal adjustment, orthodontic camouflage with or without extraction, orthodontic intervention using mini-implants or mini-plates, and even orthognathic surgery. An accurate diagnosis and etiological determination are always the best guides to establish the objectives and the ideal treatment plan for such a malocclusion. This report describes two cases of open bite. At the end of the treatment, both patients had their canines and molars in Class I occlusion, normal overjet and overbite, and stability during the posttreatment period.

A mordida aberta tem fascinado enormemente a Ortodontia devido à dificuldade de tratamento e manutenção da estabilidade. É uma anomalia com características distintas que, além da complexidade dos múltiplos fatores etiológicos traz consequências estéticas e funcionais. De acordo com a etiologia, muitas mecânicas têm sido utilizadas no tratamento da mordida aberta, entre elas, grades palatinas, forças ortopédicas, ajuste oclusal, terapia de camuflagem com ou sem exodontias, intervenção ortodôntica com auxilio de mini-implantes ou mini-placas até a cirurgia ortognática. Considerando que um diagnóstico apropriado e a determinação da etiologia sempre serão os melhores guias para conduzir os objetivos e o plano de tratamento ideal desta maloclusão, dois casos de mordida aberta foram apresentados. Ao final do tratamento ambos os casos apresentaram oclusão de Classe I de caninos e molares, trespasse horizontal (overjet) e trespasse vertical (overbite) normais e na avaliação pós-contenção, mostraram estabilidade.

Conservative treatment of an ankylosed tooth after delayed replantation: a case report.

An 8-year-old boy sustained avulsion of his upper right maxillary central incisor and lateral luxation of his upper left maxillary incisors. Subsequently, the upper right maxillary central incisor developed replacement resorption, and both upper left maxillary incisors developed pulpal canal obliteration. In the ankylosed tooth, decoronation procedure was performed, and in the 44-month follow-up period the involved alveolar site showed vertical apposition of bone and continuing replacement resorption. Decoronation is a surgical procedure that allows preservation of the bone volume for the future, avoiding aesthetic disturbances and more aggressive treatments in cases where other therapeutic alternatives are not feasible.

Aspectos clínicos e histológicos da anquilose múltipla de molares decíduos: relato de caso / Clinical and histological aspects of multiple ankylosis of primary molars: case report

A anquilose dentoalveolar de molares decíduos consiste na fusão anatômica do cemento e/ou dentina ao osso alveolar, cujo exame clínico, na maioria dos casos, é o principal recurso para o diagnóstico. Quanto menor o grau de severidade da infra-oclusão decorrente da anquilose e quanto mais precocemente esta for diagnosticada, menores serão as seqüelas desta anomalia. Atualmente, a conduta preconizada é o controle clínico e radiográfico dos casos de anquilose leve e moderada e exodontia nos casos de anquilose severa, considerando que as características individuais do paciente são importantes na decisão do tratamento. Este trabalho tem como objetivo discutir os principais aspectos clínicos e histológicos desta anomalia e apresentar um caso clínico de anquilose múltipla, com acompanhamento de cinco anos, abordando uma prosta de tratamento
