ABSTRACT
Los terceros molares heterotópicos son dientes que se encuentran incluidos en los maxilares y la mandíbula distantes a su sitio de erupción habitual. Su etiología no está bien definida y existen diversas teorías. Estos dientes pueden aparecer en diferentes zonas de las estructuras óseas, teniendo predilección por la mandíbula. Suelen aparecer entre la segunda y la séptima década de la vida, la mayoría de los casos son hallazgos imagenológicos en la consulta odontológica. El tercer molar mandibular es el diente que presenta heterotopía con mayor frecuencia, siendo su localización habitual en rama mandibular y en la región subcondílea. El quiste dentígero es la patología asociada más común. Presentamos un caso de tercer molar heterotópico en rama mandibular derecha de larga evolución, relacionado a un quiste dentígero, el cual se manejó bajo anestesia regional. Se describe la etiología, técnica quirúrgica y consideraciones especiales relacionados con los dientes heterotópicos (AU)
Heterotopic third molars are teeth that are embedded in the maxilla and mandible, remote from their usual eruption site. Its etiology is not well defined and there are various theories at the moment. These teeth can appear in different areas of the bone's structures, having a predilection for the jaw. They usually appear between the second and seventh decade of life, and in most cases are imaging findings. The mandibular third molar is the tooth with the most frequent heterotopia, being its usual location in the mandibular branch and in the subcondylar region. The dentigerous cyst is the most common associated pathology. We present a case of a long evolution heterotopic third molar in the right mandibular branch, related to a dentigerous cyst which was managed under local anesthesia. The etiology, surgical technique and special considerations related to heterotopic teeth are described (AU)

Dentes ectópicos são frequentemente encontrados, entretanto, terceiros molares inferiores ectópicos são inco-muns, com etiologia obscura e pouco descritos na literatura pertinente. Sua localização já foi relatada nas regiões condilar, subcondilar, incisura mandibular, ângulo e borda inferior da mandíbula. Devido à importância do plane-jamento terapêutico, manejo adequado e variedade das manifestações clínicas desta condição, este trabalho teve como objetivo relatar um caso clínico de terceiro molar inferior ectópico na região de incisura mandibular, com radiolucência aumentada ao redor da coroa, em um paciente do gênero masculino, de 28 anos e sem sintomato-logia. Acompanhamento radiográfico pode ser indicado, no entanto, em pacientes sintomáticos ou com alterações patológicas associadas, a extração deve ser considerada. Diante disso, o tratamento de escolha foi a extração do dente 38 sob anestesia geral, por via intraoral, tendo em vista a posição dentária, radiolucência e morbidade as-sociada à cirurgia. O tecido mole circundante foi enviado para análise anatomopatológica. O paciente evoluiu sem intercorrências durante avaliação pós-operatória (AU)
Ectopic teeth are frequently found, however, ectopic lower third molars are uncommon, with obscure etiology and little described in the pertinent literature. Its location has been reported in the condylar, subcondylar, mandibular notch, angle and lower edge of the mandible. Due to the importance of therapeutic planning, adequate manage-ment and variety of clinical manifestations of this condition, this study aimed to report a clinical case of an ectopic lower third molar in the region of the mandibular notch, with increased radiolucency around the crown, in a male gender pacient, 28 years old and without symptoms. Radiographic follow-up may be indicated, however, in symp-tomatic patients or patients with associated pathological changes, extraction should be considered. Therefore, the treatment of choice was the extraction of tooth 38 under general anesthesia, intraorally approach, considering the dental position, radiolucency and morbidity associated with the surgery. The surrounding soft tissue was sent for anatomopathological analysis. The patient evolved uneventfully during the postoperative evaluation (AU)

Los terceros molares heterotópicos son órganos dentarios que se encuentran en un sitio anatómico fuera de lo habitual, pueden ser supernumerarios, deciduos o un diente permanente, el cual ha sido reportado en diferentes posiciones, incluyendo la región coronoidea, cavidad nasal, seno maxilar, región orbitaria, palatina, cóndilo mandibular. La etiología de la erupción heterotópica/ectópica es desconocida, aunque hay varias teorías como la discrepancia óseo-dentaria por la evolución. Los órganos dentarios heterotópicos/ectópicos son comunes en la mandíbula y en el género femenino y pueden ocurrir en ambas denticiones. Algunos terceros molares heterotópicos/ectópicos son asintomáticos durante el periodo de vida y son usualmente detectados en hallazgos clínicos y radiográficos de manera incidental. Existen casos documentados desde 1887 hasta la actualidad cuya localización es en el reborde orbitario. En el presente artículo se expone un caso clínico de una extracción quirúrgica de un tercer molar superior heterotópico en el reborde orbitario descrita bajo el protocolo de las retenciones dentales. Dicho caso fue establecido en el Hospital Regional «General Ignacio Zaragoza¼ del ISSSTE en la Ciudad de México, con el que se obtuvieron resultados favorables, fue el primer reporte de la literatura en México. Se realizó una revisión aleatoria de la literatura en páginas como PubMed, ScienceDirect y Springer, Cochrane Library y se desarrolló el reporte de caso clínico de una paciente con un tercer molar superior heterotópico ubicado en el piso de órbita derecho (AU)
Heterotopic third molars are dental organs that are in an anatomical site out of the ordinary, can be supernumerary, deciduous or a permanent tooth, which has been reported in different positions, including the coronoid region, nasal cavity, maxillary sinus, orbital region, palatal, mandibular condyle. The etiology of the heterotopic/ectopic eruption is unknown, although there are several theories such as bone-dental discrepancy due to evolution. The heterotopic/ectopic teeth are common in the jaw and in the female gender and can occur in both dentitions. Some heterotopic/ectopic third molars are asymptomatic during the lifetime and are usually found incidentally in clinical and radiographic findings. There are documented cases from 1887 to the present that its location is in the orbital rim. In the present article we present a clinical case of a surgical extraction of a third upper molar heterotopic in the orbital rim and that is described under the dental retention protocol established in the Regional Hospital «General Ignacio Zaragoza¼ of the ISSSTE in the City of Mexico, with which they obtain favorable results, first report of the literature in Mexico. A randomized review of the literature was made on pages such as PubMed, ScienceDirect and Springer, Cochrane Library and the clinical case report of a patient with a heterotopic upper third molar located on the floor of the right orbit was developed (AU)

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.

Ectopic eruption of teeth within the dentate region of the jaws is frequently noticed in routine clinical practice. However, the ectopic eruption in a non-dentate region is rare, especially in the area of the maxillary sinus. Early surgical intervention for the removal of ectopic teeth along with enucleation of associated cyst, such as a dentigerous cyst, if present, is the preferred treatment. We report a case of a patient who was referred due to chronic mucopurulent discharge and epistaxis, nasal obstruction and unilateral facial pain due to an ectopic third molar. This condition was caused by an ectopic tooth near the sinus ostium; however, the patient had no dental complaints

INTRODUCTION: Dental transposition and impaction are disorders related to ectopic eruption or failure in tooth eruption, which can affect child physical, mental and social development and may be difficult to be clinically solved. METHODS: We describe a case of transposition between the upper left canine and lateral incisor associated with impaction of the central incisor on the same side, in a 12-year-old patient. Conservative treatment involving surgical-orthodontic correction of transposed teeth and traction of the central incisor was conducted. CONCLUSION: The option of correcting transposition and orthodontic traction by means of the segmented arch technique with devices such as cantilever and TMA rectangular wire loops, although a complex alternative, was proved to be esthetically and functionally effective. .
INTRODUÇÃO: transposição e impacção dentárias são distúrbios relacionados à erupção ectópica ou à falha na erupção dentária, que podem afetar o desenvolvimento físico, psíquico e social da criança, e que podem ser de difícil resolução clínica. MÉTODOS: é descrito um caso clínico de transposição entre o canino e o incisivo lateral superior esquerdo, associado à impacção do incisivo superior, do mesmo lado, em uma paciente de 12 anos de idade. Optou-se pela realização de tratamento ortodôntico-cirúrgico conservador, envolvendo a correção ortodôntica dos dentes transpostos e o tracionamento do incisivo central impactado. CONCLUSÃO: a opção pela correção da transposição e tracionamento ortodôntico com a utilização da técnica do arco segmentado com uso de dispositivos como cantiléver e alças em fios TMA retangulares, apesar de ser uma alternativa de execução complexa, mostrou-se efetiva do ponto de vista estético e funcional. .

La erupción ectópica de los incisivos centrales superiores es poco frecuente de encontrar. El tratamiento es controversial y consiste en la extracción de la pieza dentaria o su ubicación en el arco. La modalidad de tratamiento actual, en lugar de la extracción, ha utilizado la generación del espacio requerido, la exposición quirúrgica de la corona y el posicionamiento ortodóncico de la pieza dentaria. El objetivo del presente trabajo es mostrar el caso clínico de un paciente de sexo masculino en su etapa prepuberal, con 11,9 años de edad. El mismo presentaba un incisivo central superior permanente ectópico retenido en posición horizontal con anomalía de forma coronaria y dilaceración radicular. Este incisivo fue ubicado exitosamente en el arco dentario mediante la liberación quirúrgica y la posterior tracción ortodóncica. Si bien con el paso del tiempo puede llegar a perderse la pieza dentaria, el tratamiento es considerado exitoso ya que conservamos hueso y mantenemos la estética natural de la pieza dentaria en una etapa crucial de la vida. Además, en este tipo de casos es fundamental la interrelación cirugía-ortodoncia.

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.

La migración de caninos inferiores es un fenómeno poco común. Su incidencia es menor que incluidos maxilares y son frecuentemente encontrados en jóvenes. Solamente caninos, segundos premolares y terceros molares incluidos migran a lugares ectópicos en su desarrollo y dientes incluidos ectópicos son, en la mayoría de los casos, asintomáticos. La etiología es compleja y poco descrita en la literatura. Un canino es considerado un diente migrado cuando, horizontalmente, más de la mitad del diente atraviesa la línea mediana. Este artículo reporta un caso clínico, con tratamiento quirúrgico de exodoncia de caninos bilaterales incluidos, horizontalmente en la región de la sínfisis. Se observó que la exodoncia es la conducta operatoria más frecuente, presentando en este caso buenos resultados.
Migration of canine mandibles is a very uncommon phenomenon. Their incidence is less frequent than maxillary canines and present frequently in young people. Only canines, second bicuspid and third molars can migrate to ectopic areas in their development and ectopic embedded teeth are, for the most part asymptomatic. The etiology is complex and with poor information. A canine is considered a migrating tooth when it penetrates horizontally the middle line of the mandible. This paper reports a case with surgical treatment of dental extraction, including horizontal bilateral canines in the symphysis region. It was observed that dental extraction is a more frequent treatment and presented with good results in this case.

En este trabajo son descritas alteraciones en la erupción de los caninos permanentes, su etiología, diagnóstico temprano y posibilidades terapéuticas. El canino recoge todos los problemas de espacio que puedan existir en la arcada y es frecuente la erupción en una zona alta. La inclusión de los caninos tiene una etiología compleja, favorecida por factores evolutivos, anatómicos y mecánicos. La impactación mandibular es menos frecuente y su incidencia se describe como veinte veces menos que la impactación del canino maxilar. La erupción ectópica de los caninos maxilares puede estar asociada a la reabsorción de las raíces de los incisivos adyacentes. A la edad de 8 a 10 años empieza a palparse la prominencia del canino en el fondo del vestíbulo. Los métodos radiográficos más utilizados son las radiografías panorámica, oclusal y periapical, con técnicas de tubo vertical y otras angulaciones. En la actualidad, es de gran ayuda la tomografía computarizada. El término tratamiento temprano implica una terapéutica en estadios precoces de desarrollo, cuando la patología puede ser interceptada o detenida y los tratamientos más utilizados son exodoncia de caninos temporales y extracción seriada. En conclusión, las alteraciones en la erupción de caninos permanentes requiere conocimiento de los parámetros de normalidad, cronología y secuencia, junto a la aplicación de pruebas complementarias, para poder efectuar una evaluación temprana y pertinente y evitar las complicaciones derivadas de un diente impactado.
This study describes the alterations in the eruption of the permanent canines, etiology, early diagnosis and therapeutic possibilities. The canine one gathers all the problems of space that can exist in the arches and is frequent the eruption in a high zone. The inclusion of the canine has a complex etiology, favored by evolutionary, anatomical and mechanical factors. The mandibular impaction is less frequent and its incidence is described less like twenty times than the impaction of the maxilar canine one. The ectopic eruption of maxillary canines can be associated to the reabsorbing by the roots of the adjacent incisors. From 8 to 10 years begins to be noticed the prominence of the canine in the bottom of vestibule The most used radiographies methods are the panoramic x-ray, oclusals and periapicals with techniques of vertical tube and other angles. At the present time it is helpful the computed tomography. The term "early treatment" implies a therapeutic action in early stages of development, when the pathology can be intercepted or stopped, and the most used are exodontias of temporary canines and serial extraction. In conclusion, the canine alterations of the eruption of permanent involve knowledge of the normality parameters, chronology and sequence, along with the development of complementary tests, to carry out an early and pertinent evaluation and to avoid the complications derived from an impacted tooth.

Este artigo visa abordar aspectos atinentes à etiologia de dentes com retardo eruptivo. Para isso, um caso clínico controvertido, de manifestaçäo local, foi discutido, sob a ótica obstrutiva, traumática, desenvolvimental e idiopática. Finalmente, apesar de um número razoável de publicaçöes, a etiologia de dentes com retardo eruptivo nem sempre é evidente nas ausências de um fator obstrutivo ou sem antecedente traumático
