Surgery traction canine of impacted in the maxillary: a case report / Cirurgia de tracionamento de canino impactado em maxila: relato de caso

ABSTRACT Permanent canines are essential for the preservation of the stomatognathic system, as they are part of the occlusal and aesthetic function and balance. During the normal development of occlusion, canines follow a long and complex trajectory until their eruption, that is, they are more likely to suffer disturbances during this process. Removal of the permanent canine should only be considered in extreme cases, where the canine itself is not susceptible to orthodontic traction. Orthodontic traction is the most indicated treatment due to the high morphofunctional and aesthetic value of the permanent canine. The aim of this study is to report a clinical case of traction surgery of the superior permanent canine included in the maxilla. A 13-year-old female patient attended the dental clinic at the Nilton Lins University accompanied by her guardian, referred by an orthodontistfor canine traction surgery. during the examIn the clinical analysis, tooth 13 was absent from the dental arch. The patient had a computed tomography scan, where it was possible to verify the actual position of the toothimpacted with the partially erupted crown on the alveolar ridge. After planning, surgery was performed to install an orthodontic button and adapt the ligature with a 0.30 mm wire. After the 10-month follow-up period, the presence of the tooth in arch, completely erupted, was observed, showing effectiveness in the proposed treatment. Therefore, the procedure for bonding the orthodontic device was performed satisfactorily without complications or intercurrences, making it possible to continue the orthodontic treatment. The patient remains under follow-up.

RESUMO Os caninos permanentes são essenciais para a preservação do sistema estomatognático, visto que, fazem parte da função e equilíbrio oclusal e estético. Durante o desenvolvimento normal da oclusão, os caninos seguem uma longa e complexa trajetória até seu irrompimento, ou seja, estão mais propensos a sofrerem distúrbios no decorrer desse processo. A extração do canino permanente só deve ser considerada em casos extremos, onde o próprio não se encontra suscetível à tração ortodôntica. O tracionamento ortodôntico é o tratamento mais indicado devido ao alto valor morfofuncional e estético do canino permanente. Sendo assim, o objetivo deste estudo é relatar um caso clínico de cirurgia de tracionamento de canino permanente superior incluso em maxila. Paciente de 13 anos, gênero feminino, compareceu a clínica odontológica da Universidade Nilton Lins acompanhado de seu responsável, encaminhada por um ortodontista para cirurgia de tracionamento de canino. Durante o exame clínico observou-se ausência do dente 13 na arcada dentária. A paciente apresentou a tomografia computadorizada, onde foi possível verificar o real posicionamento do dente impactado com a coroa parcialmente irrompida no rebordo alveolar. Após o planejamento, realizou-se a cirurgia destinada a instalação de botão ortodôntico e adaptação da amarrilha com fio 0,30 mm. Posteriormente ao período de acompanhamento de 10 meses, observou-se a presença do dente em arco, totalmente erupcionado, mostrando efetividade no tratamento proposto. Portando, o procedimento de colagem de dispositivo ortodôntico ocorreu de forma satisfatória sem complicações ou intercorrências, tornando possível a continuidade do tratamento ortodôntico. A paciente permanece em acompanhamento.

Invasive cervical resorption of central incisor during orthodontic treatment

ABSTRACT Introduction: Invasive cervical resorption (ICR) is a relatively rare type of ERR (External Root Resorption), in which a localized resorption begins in the cervical area of the tooth, below the epithelial junction and above the ridge crest. Objective: Describe the clinical case of an 11-year-old boy with no dental trauma history, presenting moderate crowding and ectopic eruption of the maxillary right central incisor. He had been undergoing orthodontic treatment elsewhere, and his family was dissatisfied with the results. Description: A new treatment was indicated, which included rapid maxillary expansion followed by extraction of four premolars. During routine panoramic evaluation, a radiolucid image was detected and a periapical radiograph was requested. At this point, an ICR of the maxillary right central incisor was found. The treatment was cautiously finalized and despite the use of light forces, central incisor was severally compromised by ICR and was therefore extracted. Conclusion: This clinical example discusses the importance of routine radiographs for the early diagnoses of ICR.

RESUMO Introdução: A reabsorção cervical invasiva (RCI) é um tipo relativamente raro de reabsorção radicular externa (RRE), no qual uma reabsorção localizada começa na região cervical do dente, abaixo da junção epitelial e acima da crista marginal. Objetivo: Descrever o caso clínico de um menino com 11 anos de idade, sem histórico de trauma dentário, apresentando apinhamento moderado e erupção ectópica do incisivo central superior. Ele realizava tratamento ortodôntico em outro local, mas sua família estava insatisfeita com os resultados. Descrição: Foi iniciado um novo tratamento, que incluiu a expansão rápida da maxila, seguida pela extração de quatro pré-molares. Durante a avaliação de rotina da radiografia panorâmica, uma imagem radiolúcida foi detectada, e uma radiografia periapical da região foi solicitada, sendo encontrada uma RCI no incisivo central superior direito. O tratamento foi finalizado com cautela e, apesar do uso de forças leves, o incisivo central estava seriamente comprometido pela RCI e, portanto, precisou ser extraído. Conclusão: Esse exemplo clínico discute a importância das radiografias de rotina para o diagnóstico precoce da RCI.

Transmigración de canino mandibular: etiología, manejo quirúrgico y consideraciones especiales / Mandibular canine transmigration: etiology, surgical management and special considerations

En raras ocasiones, el canino mandibular derecho o izquierdo se coloca en el lado opuesto al habitual. Esta perturbación se define como la transmigración. Existen diversas teorías de su etiología, así como factores que la condicionan. La transmigración mandibular es un término que no está descrito en la literatura contemporánea y son pocos los casos reportados a nivel mundial. Presentamos un caso de trasmigración de canino mandibular derecho, posicionado por debajo del agujero mentoniano de lado izquierdo, cerca del borde basal mandibular, el cual se extrajo bajo anestesia general. Presentamos la etiología, técnica quirúrgica y consideraciones especiales en casos de trasmigración de canino mandibular (AU)

In rare occasions right or left mandibular canine is positionated at opposed side of habitual. This disturbance is defined as transmigration. There exist diverse theories about its etiology as well as conditioning factors. Mandibular transmigration is a non described term in modern literature and there are only a few reported cases at world level. We present one case of right canine transmigration positionated intimately below of left side mentonian hole near of mandibular basal edge which it was extracted under general anesthesia.

Supernumerary: the Importance of Early Orthodontic Treatment / Supranumerário: a Importância do Tratamento Ortodôntico Precoce

The presence of supernumeraries may lead to irruptive problems, such as impacted teeth, functional and aesthetic disorders. The present study describes two clinical cases, with anterior teeth eruption disorders caused by additional dental elements, treated early. Patients presented with aesthetic involvement, with delay in the emergence of the upper incisors. The clinical and radiographic examinations detected the presence of obstacles to the teeth eruption. Early treatment with 2x4 appliance was realized, followed by final corrective orthodontics. After restoration of the dimension for retained teeth, there was spontaneous eruption in clinical case 1 and need of traction in clinical case 2. When patients reached the complete permanent dentition, a corrective phase was performed with the objective of detailing the dental occlusion and finishing the treatment. The early diagnosis of teeth impacted and supernumerary, provide the achievement of adequate occlusion and positive aesthetic of patients, with good prognosis, avoiding psychological and functional problems caused by absence of anterior teeth. (AU).

A presença de supranumerários pode ocasionar problemas irruptivos, como impacção de dentes, desordens funcionais e estéticas. O presente trabalho descreve dois casos clínicos abordados precocemente, com alterações na irrupção de dentes anteriores devido a presença de supranumerários. Os pacientes apresentavam queixas estéticas, com atraso no aparecimento dos incisivos superiores. Os exames clínico e radiográfico detectaram a presença de barreiras irruptivas. Realizou-se tratamento precoce com auxílio da mecânica 4x2, seguido pela ortodontia corretiva final. Após etapa de restabelecimento da dimensão para os dentes retidos, houve irrompimento espontâneo no caso clínico 1 e necessidade de tracionamento no caso clínico 2. Quando pacientes atingiram a dentição permanente completa, realizou-se uma fase corretiva com o objetivo de detalhamento da oclusão dentária e finalização do tratamento. O diagnóstico precoce de impacção dentária e detecção de supranumerários favoreceu a restituição de oclusão adequada e estética dos pacientes, com prognóstico muito favorável, evitando problemas psicológicos e funcionais provocados pela ausência de dentes anteriores.

A Rare Case Report of Ectopic Tooth in Submandibular Salivary Gland’s Duct

@#This case report highlights mandibular tooth in an ectopic position in the floor of the mouth, associated with submandibular salivary gland, which was completely obliterating the Wharton duct. Very few such cases have been reported in the literatures. Since ectopic tooth may lead to pain, discomfort sensation upon mastication, and even infection (sialadenitis), its diagnosis and treatment is essential.

Tercer molar ectópico en seno maxilar: reporte de un caso / Ectopic third molar in maxillary sinus: report of a case

Los dientes ectópicos son órganos dentarios que se encuentran enuna región diferente a la habitual, existen publicaciones que reportanórganos dentarios ectópicos en la región maxilofacial siendo sitioscomunes el paladar, región paraorbitaria, cavidad nasal, seno maxilar, mentón, apófisis corónides y cóndilo. También se han publicado casos de zonas más alejadas como ovario o región anterior del mediastino,que por lo general están relacionados con un teratoma. En su mayoría son hallazgos radiográficos, por lo que en general son asintomáticos. Al encontrarse dentro del seno maxilar su terapéutica puede ser conservadora,bajo vigilancia clínica-radiográfi ca o quirúrgica mediante endoscopia, abordaje transnasal, Caldwell-Luc o abordaje cuadrangular. La extracción de estos órganos dentarios es necesaria por la tendencia que presentan a formar quistes, desarrollar tumores odontogénicos y desencadenar alteraciones neuropáticas. Se reporta el caso de una paciente de 32 años de edad con diagnóstico de tercer molar ectópico en región de antro maxilar.

Ectopic tooth are dental organs found in a uncomon regions. There arepublication that report ectopic tooth in the maxillofacial region beingcommon sites palate, paraorbitaria region, nasal cavity, maxillarysinus, chin, coronides process and condyle. Cases have also beenreported in non-dental areas such as ovary, anterior mediastinum regionusually related to a teratoma. Ectopic tooth are often radiographicfi ndings because they are generally asymptomatic. Its therapeuticwhen found in the maxillary sinus could be conservative under periodicclinical-radiographic vigilance. Removal of these dental organs isnecessary for their tendency to form cysts, develop odontogenic tumorsand trigger neuropathic disorders. Surgical options are endoscopic,transnasal, Caldwell Luc or quadrangular approach. We present acase of a female of 32 years old with a diagnosis of ectopic third molarin maxillary antrum.

Abordagem clínica da erupção ectópica de um primeiro molar permanente superior - Relato de caso / Clinical management of the ectopic eruption of a maxillary first permanent molar - Case report

Ectopic eruption is a concept including those clinical cases in which teeth show abnormal eruption pattern and erupt ectopically, in an incorrect position. This abnormality has been pointed out in the literature for the first permanent molars, mainly the maxillary ones. There is no specific etiological factor for this abnormality in the first permanent molar, but different factors are reported. The early approach of the ectopic eruption of the first permanent molar can prevent effects such as the early root resorption of the adjacent deciduous second molar and the loss of space for eruption of the premolar successor as well. The purpose of this paper was to report a ectopic eruption of a maxillary first permanent molar diagnosed in a nine-year-old patient with severe root resorption of the adjacent deciduous second molar. A simple and effective therapeutic approach was implemented to treat such abnormality. This clinical case was followed until complete eruption of the premolar successor.

Erupção ectópica é um conceito utilizado para designar aqueles casos em que os dentes apresentam algum desvio em seu padrão normal de erupção, ou seja, erupcionam numa posição atípica. Esta condição tem sido descrita na literatura para os primeiros molares permanentes, principalmente os superiores. Não há um fator etiológico específico para a erupção ectópica do primeiro molar permanente, onde diferentes fatores são relatados. A abordagem precoce da erupção ectópica do primeiro molar permanente poderá evitar sequelas, tais como a reabsorção radicular precoce do segundo molar decíduo adjacente, bem como a perda de espaço para erupção do pré-molar sucessor. O objetivo deste trabalho é descrever um caso de erupção ectópica de um primeiro molar permanente superior, em uma paciente de nove anos de idade, com reabsorção radicular severa do segundo molar decíduo adjacente. Uma abordagem terapêutica simples e efetiva foi adotada para o tratamento da erupção ectópica. O caso foi acompanhado até a completa erupção do segundo pré-molar sucessor.

A Case of Ectopic Tooth with Superimposed Fungal Infection in Nasal Cavity of Cleft Lip and Palate Patient / 대한이비인후과학회지

Ectopic teeth (ET) occur in a wide variety of sites such as palate, mandibular condyle, coronoid process, orbit, maxillary antrum and nasal cavity. To date, the precise etiology of ET is still unknown. Although ET can be present in patients without any associated syndrome or development anomaly, it can be frequently associated with cleft lip, palate or other syndromes such as Gardner's syndrome, cleidocranial dysplasia, and etc. The Candida species are yeast fungi, which are pathogenic saprophytes, but the infection of the nose and sinuses is rare. We report a case of cleft lip and palate patient presenting with a history of foul odor, who was found to have an ectopic tooth in the nasal cavity with superimposed candidal infection.

Clinical Features of Ectopic Tooth Occurring in Sinonasal Cavity / 대한이비인후과학회지

BACKGROUND AND OBJECTIVES: The presence of ectopic tooth in the sinonasal cavity is an unusual phenomenon and the underlying etiology remains unclear. Because of its rarity, clinical observation studies about sinonasal ectopic tooth are very rare. The aim of this study was to analyze the clinical characteristics of ectopic tooth occurring in the sinonasal cavity. SUBJECTS AND METHOD: Medical records and radiologic studies of 11 patients, who were treated between January 2006 and June 2012 for ectopic nasal teeth were reviewed retrospectively, with regard to sex, age, location, symptoms and treatment methods. RESULTS: Among 11 patients, 8 patients were male and 3 patients were female. The average age was 24.2 years. Among 7 patients who had symptoms, nasal obstruction was the most common followed by rhinorrhea, postnasal drip, facial swelling or pain, headache. The nasal cavity was the most frequently affected site. Among 14 ectopic teeth from eleven patients, 7 were removed by intrasnasal endoscopy and 2 by external premaxillary approach. Five teeth which were unerupted within the hard palate or maxillary sinus were offered conservative treatment with periodic follow-up. CONCLUSION: Removal of ectopic nasal tooth is generally advocated to alleviate the symptoms and prevent complications; if conservative treatment is decided, periodic monitoring of the patient is recommended. We suggest that treatment be carefully planned based on the symptoms of patients, location of the ectopic tooth, and whether the tooth is erupted or not.

A Case of Ectopic Tooth in the Maxillary Sinus Associated with a Mucocele / 대한이비인후과학회지

Supernumerary, ectopic tooth eruption in a non-dental area is a rare entity. The ectopic development of tooth found in non-dental environment has been reported in places such as the nasal cavity, chin, maxillary sinus, mandibular bone, palate and orbital cavity. Ectopic tooth eruptions in the maxillary sinus are usually asymptomatic and are found incidentally during routine clinical or radiological investigations. The diagnosis is usually made by plain-film radiography. Computed tomography is indicated when an ectopic tooth is found prior to surgery. Standard treatment for an ectopic tooth is extraction of the tooth. Here, the authors present a case of supernumerary, ectopic tooth found in the maxillary sinus associated with a mucocele.

Ectopic Eruption of a Tooth into the Nasal Cavity with Sinusitis: A Case Report

The ectopic eruption of teeth into the nasal cavity is a rare phenomenon. Ectopic tooth eruptions commonly occur in the palate and maxillary sinus, but have also been reported in the mandibular condyle, coronoid process, orbit, and nasal cavities. The clinical manifestations of intranasal teeth are quite variable; however, intranasal teeth can be an incidental finding during routine examination in patients without nasal discomfort. Herein we report a unique case of an intranasal ectopic tooth that erupted into the nasal cavity and caused significant nasal symptoms in an otherwise healthy patient. The intranasal tooth was removed endoscopically.

A Case of Supernumerary Tooth within Fungus Ball in the Maxillary Sinus / 대한이비인후과학회지

The ectopic eruption of a supernumerary tooth can occur in the sinonasal area, but due to its rarity, few cases of ectopic tooth eruption in the maxillary sinus have been reported. A fungus ball in the paranasal sinuses usually involves just one sinus, most frequently the maxillary sinus. Here, the authors present a case of an ectopic supernumerary tooth embedded in a fungus ball of the maxillary sinus.

Tercer molar ectópico impactado en zona retromolar: reporte de caso / Ectopic and impacted third molar in retromolar zone: a case report

El desarrollo dentario resulta de una complicada interacción entre el epitelio oral y el tejido mesenquimático subyacente. La interacción anormal de tejidos en este período podría resultar en el desarrollo y erupción de un diente ectópico. Terceros molares incluidos son una de las patologías más frecuentes encontradas en cirugías oral y maxilofacial. Su evaluación generalmente es radiográfica, y los de ubicación mesioangular son los más prevalentes en la mandíbula. El presente reporte muestra un caso clínico de tercer molar incluido en la región retromolar mandibular. El diagnóstico se efectuó durante una evaluación por medio del análisis de una ortopantomografía en un paciente de sexo femenino de 51 años de edad. La pieza estaba ubicada en la zona retromolar mandibular derecha inmediatamente subcortical. Dado que se encontraba asintomática, sin signos radiográficos ni clínicos de patología, no fue indicada la exodoncia; sin embargo, es importante considerar esta variación anatómica y una posible resolución quirúrgica de ella ante la posible rehabilitación protésica del área.

Tooth develop results of several interactions between oral epithelium end underlying mesenchymatic tissue during odontogenesis. Abnormal relation of tissues could result in develop and eruption of an ectopic tooth. Impacted third molars are a frequent pathology in oral and maxillofacial surgery, it evaluation is commonly radiographic, and the most frequent position in jaw bone is mesioangular. This report wants to show an impacted third molar in mandibular retromolar region. Diagnosis was done through a orthopantomographic study during a clinical evaluation of 51 years of age female patient. Teeth was found sub cortical of right retromolar zone. Considering patient did not related or shown clinical signs of pathology, and radiograph neither had disease compatible signs, was resolved do not proceed to extraction. However, is important to consider this anatomical variation and a possible surgical resolution if a prosthetic rehabilitation of this area.

Removal of extensive maxillary dentigerous cyst via a Caldwell-Luc procedure

A case of a large dentigerous cyst associated with canine tooth in the maxillary antrum is presented. This case is of interest because of its extensiveness and the presence of an ectopic tooth in the roof of the maxillary sinus. Theoretical aspects of canine impaction and cyst formation are reviewed. The management of a jaw cyst, in particular, the still popular Caldwell-Luc procedure is discussed.
