ABSTRACT

Objetivo: relatar um caso raro de impacção de um incisivo decíduo inferior pela presença de odontoma composto, bem como descrever a sua abordagem clínica. Relato de caso: paciente do sexo masculino, com 4 anos de idade, apresentava ausência do incisivo lateral decíduo inferior esquerdo. O exame radiográfico mostrou impacção do incisivo não erupcionado próximo a estruturas radiopacas sugestivas de odontoma composto. O paciente foi acompanhado por dois anos, momento em que se realizou abordagem cirúrgica do caso. Após a cirurgia, a hipótese de diagnóstico de odontoma composto foi confirmada e com o acompanhamento ocorreu a erupção dos incisivos centrais permanentes inferiores. O paciente foi encaminhado para tratamento ortodôntico. Considerações finais: esse relato de caso aborda um caso raro de odontoma composto associado à não erupção de dente decíduo, uma vez que odontomas costumam ser detectados preferencialmente na segunda década de vida do paciente, sendo associados à impacção de dentes permanentes. Além disso, apresenta um protocolo de abordagem clínica para esses casos quando diagnosticados em idade precoce no paciente infantil.(AU)


Objective: to report a rare case of impaction of a primary mandibular incisor due to the presence of a compound odontoma and describe its clinical management. Case report: a 4-year-old boy presented with a "missing" primary left mandibular lateral incisor. Radiographs showed impaction of the unerupted incisor by adjacent radiopaque structures consistent with a compound odontoma. The patient was recalled periodically for 2 years, at which time surgical excision was performed. The diagnosis of compound odontoma was confirmed histologically, and the permanent mandibular central incisors erupted uneventfully; the patient was referred for orthodontic treatment. Final considerations: this case report describes an unusual case of compound odontoma associated with an unerupted deciduous tooth; odontomas are rare in this age range, occurring predominantly in the second decade of life and in association with impaction of permanent teeth. We also propose a protocol for clinical management of such early-onset cases.(AU)

ABSTRACT

RESUMEN: Uno de los problemas con mayores consecuencias tanto estéticas como funcionales en ortodoncia es la impactación de caninos maxilares (ICM) siendo principal motivo de reabsorciones radiculares de dientes adyacentes. Actualmente se carece de estudios que describan la reabsorción radicular por ICM a través de tomografía computarizada conebeam (TCCB) en la población chilena. El objetivo del estudio fue describir a pacientes entre 8 a 18 años, que presentan ICM (o riesgo de ella), tanto en las características de la impactación canina como en la reabsorción radicular presentada en incisivos laterales (IL) y en otros dientes adyacentes. En este estudio retrospectivo, 135 datos de TCCB fueron seleccionados por conveniencia, de los cuales 181 caninos presentaron ICM. Fueron analizadas las variables edad, sexo, tipo de ICM (unilateral o bilateral), localización bucolingual (vestibular o palatino), lado de impactación (derecho o izquierdo), reabsorción radicular en el incisivo lateral y registro de el o los dientes anexos afectados por reabsorción radicular (incisivo central y/o premolares). Además en el caso de reabsorción de IL fue analizada la reabsorción tridimensionalmente a través de la ThreeDimensional Leeds Orthodontic Root Resorption Target Scale (3D-LORTS). La ICM en la muestra seleccionada tuvo una edad promedio de 12 años, una relación por sexo mujeres:hombres de 1,5:1, frecuentemente de tipo unilateral, en el lado derecho y una localización bucolingual palatina (64,1 %) por sobre la vestibular (35,9 %). La reabsorción radicular alcanzó un 35,9 %, de la cual un 27,6 % involucró a IL y un 8,3 % en dientes anexos adyacentes. En cuanto a la distribución tridimensional de la reabsorción radicular, la más frecuente involucró el tercio apical (60 %), con compromiso pulpar o severo (40 %), involucrando solo una cara, la palatina (54 %). Ninguna de las variables anteriores consideradas, demostró diferencias estadísticas con la reabsorción radicular de incisivos laterales.


ABSTRACT: One of the problems with greatest aesthetic and functional consequences in orthodontics is the Impaction of Maxillary Canines (ICM) being the main reason for root resorption of the adjacent teeth. Currently there are no studies describing root resorption by ICM through cone beam computed tomography (CBCT) in the Chilean population. The main objective of the study was to describe patients between 8 and 18 years old, who presented with ICM (or risk thereof), with the characteristics of canine impaction as well as root resorption presented in lateral incisors (IL) and in other adjacent teeth. In this retrospective study, 135 CBCT subjects were selected for convenience, of which 181 canines presented ICM. The variables were analyzed: age, sex, type of ICM (unilateral or bilateral), buccolingual location (vestibular or palatal), side of impaction (right or left), root resorption in the lateral incisor and registration of adjacent teeth affected by resorption radicular (central incisor and/or premolars). In addition, when reabsorption of IL was observed, three-dimensional analysis was made using the Three-Dimensional Leeds Orthodontic Root Resorption Target Scale (3D-LORTS). The ICM in the selected sample had an average age of 12 years, a ratio by sex of women:men of 1.5:1, frequently of unilateral type, on the right side and with palatine buccolingual location (64.1 %) above the vestibular (35.9 %). Root resorption reached 35.9 %, of which 27.6 % presented in the IL and 8.3 % in adjacent teeth. Regarding the three-dimensional distribution of root resorption, the most frequent involved the apical third (60 %), with pulpal or severe damage (40 %), in only one location, the palatine (54 %). None of the above variables considered showed statistical differences with the root resorption of lateral incisors.

ABSTRACT

Abstract Objective: To investigate the prevalence of maxillary canine impaction and whether the impacted canine cases have had a potentially good or poor prognosis if interceptive treatment was practiced at earlier ages. Material and Methods: 1755 panoramic radiographs of patients, aged 13 to 60 years, attending the University of Babylon, College of Dentistry for the period from November 2016 to July 2018 were collected and assessed for the presence of impacted maxillary canines. Subsequently, four suggested prognostic factors for each impacted canine were analyzed and recorded. Results: The prevalence of maxillary canine impaction was 119 (6.78%) with 89 unilateral impaction and 30 bilateral impaction resulting in a total of 149 impacted canines. Regarding the gender, impaction was more evident in females 70 than in males 49 with no statistical significant difference. For the side, impaction was more prevalent on the left (77) than on the right (72), also with no statistical difference (p>0.05). Following the analysis of the four prognostic factors, most of the cases, 117 (78.5%) had at least one prognostic factor to be poor. Although 82 (55%) of the cases had at least one prognostic factor to be good, only 4 had all the prognostic factors to be good. Conclusion: Although the cases that had a potentially good prognosis were little (4 cases), interceptive extraction of primary canines would mostly be beneficial for these patients as it will minimize the treatment time, cost and complications.

ABSTRACT

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. We present also the etiology, surgical technique and special considerations of mandibular canine transmigration cases (AU)

ABSTRACT

ABSTRACT This report describes the oral manifestations of renal tubular acidosis (RTA) associated with secondary rickets and discusses the biological plausibility of these findings. The characteristic electrolyte changes during RTA or genetic mutations that trigger RTA may be responsible for impaired amelogenesis, dental malocclusion, impacted teeth, and absent lamina dura. This report reinforces the possibility of an association between RTA and the oral manifestations described.


RESUMO Este relato de caso descreve as manifestações bucais da acidose tubular renal (ATR) associada ao raquitismo secundário e discute a plausibilidade biológica desses achados. As alterações eletrolíticas características da ATR ou as mutações genéticas que a desencadeiam podem ser responsáveis pela amelogênese imperfeita, maloclusão dentária, dentes impactados e ausência de lâmina dura. Este relato reforça a possibilidade de uma associação entre ATR e as manifestações bucais descritas.

ABSTRACT

ABSTRACT The early recognition of risk factors for the occurrence of palatally displaced canines (PDC) can increase the possibility of impaction prevention. Objective To estimate the risk of PDC occurrence in children with dental anomalies identified early during mixed dentition. Material and Methods The sample comprised 730 longitudinal orthodontic records from children (448 females and 282 males) with an initial mean age of 8.3 years (SD=1.36). The dental anomaly group (DA) included 263 records of patients with at least one dental anomaly identified in the initial or middle mixed dentition. The non-dental anomaly group (NDA) was composed of 467 records of patients with no dental anomalies. The occurrence of PDC in both groups was diagnosed using panoramic and periapical radiographs taken in the late mixed dentition or early permanent dentition. The prevalence of PDC in patients with and without early diagnosed dental anomalies was compared using the chi-square test (p<0.01), relative risk assessments (RR), and positive and negative predictive values (PPV and NPV). Results PDC frequency was 16.35% and 6.2% in DA and NDA groups, respectively. A statistically significant difference was observed between groups (p<0.01), with greater risk of PDC development in the DA group (RR=2.63). The PPV and NPV was 16% and 93%, respectively. Small maxillary lateral incisors, deciduous molar infraocclusion, and mandibular second premolar distoangulation were associated with PDC. Conclusion Children with dental anomalies diagnosed during early mixed dentition have an approximately two and a half fold increased risk of developing PDC during late mixed dentition compared with children without dental anomalies.

ABSTRACT

Los odontomas están compuestos de esmalte, dentina, cemento y tejido pulpar. Histológicamente se clasifican en 2 grupos: compuestos y complejos, mientras que clínicamente se clasifican en 3 tipos: odontoma central (intraóseo), odontoma periférico (extraóseo o de los tejidos blandos) y odontoma erupcionado. Epidemiológicamente son reportados como los tumores odontogénicos más frecuentes, sin embargo la erupción de este tipo de lesión es poco común, produciéndose en el 1,6% de los casos. Por lo general son asintomáticos, siendo comúnmente un hallazgo radiográfico, y en algunos casos pueden estar asociados con alteraciones de la erupción dentaria. Este estudio corresponde a un caso clínico de un odontoma complejo de gran tamaño que erupciona en la cavidad oral asociado a un molar retenido.


Odontomas consist of enamel, dentin, cementum, and pulp tissue. Histologically, they are classified into 2 groups: compounds and complexes. They are also clinically classified into 3 types: Central odontoma (intraosseous), peripheral odontoma (extraosseous or soft tissue odontoma) and erupted odontoma. Epidemiologically they are reported as the most frequent odontogenic tumor, however, the eruption of this type of lesion is rare, and odontoma occurs only in 1.6% of cases.

ABSTRACT

Multiple impacted teeth of idiopathic origin are a rare dental anomaly. Various local and systemic causative factors have been implicated in the literature; however, it is unknown at present about the localization of the genetic defect in the phenotype of failure of eruption. Retained primary teeth is a well-known process, but multiple permanent and supernumerary teeth that too asymptomatic is surely a rare possibility. This article aims in to consolidate and organize the available information regarding the tooth eruption failure and to collaborate the current evidence with the report of three adult sibling’s cases of failure of eruption of multiple permanent teeth in a family without a known cause.

ABSTRACT

INTRODUCTION: Although lip bumpers (LBs) provide significant clinical gain of mandibular arch perimeter in mixed-dentition patients, orthodontists are reluctant to use them due to the possibility of permanent second molar eruptive disturbances. OBJECTIVE: The present study was conducted to assess second molar impaction associated with the use of LBs, and to investigate how they can be solved. MATERIAL AND METHODS: Lateral and panoramic radiographs of 67 patients (34 females and 33 males) were assessed prior (T1) and post-LB treatment (T2). LB therapy lasted for approximately 1.8 ± 0.9 years. Concomitant rapid palatal expansion (RPE) was performed in the maxilla at LB treatment onset. Impaction of mandibular second molars was assessed by means of panoramic radiographs in relation to the position of first mandibular molars. Horizontal and vertical movements of first and second molars were assessed cephalometrically on lateral cephalometric radiographs based on mandibular superimpositions. RESULTS: Eight (11.9%) patients had impacted second molars at the end of LB therapy. Two patients required surgical correction, whereas five required spacers and one patient was self-corrected. Mandibular first molar tip and apex migrated forward 1.3 mm and 2.3 mm, respectively. Second molar tip showed no statistically significant horizontal movement. CONCLUSION: Although LB therapy increased the risk of second molar impaction, impactions were, in most instances, easily solved. .


INTRODUÇÃO: embora placas labioativas (PLAs) promovam um ganho clínico significativo no perímetro da arcada inferior em pacientes com dentição mista, ortodontistas são relutantes em usá-las devido a possibilidade de problemas eruptivos dos segundos molares. OBJETIVO: o presente estudo avaliou a impacção dos segundos molares associada ao uso das PLAs e como a impacção pôde ser resolvida. MÉTODOS: radiografias cefalométricas lateral e panorâmica de 67 pacientes (34 do sexo feminino e 33 do masculino) foram avaliadas antes (T1) e após (T2) o tratamento com PLAs, que durou aproximadamente 1,8 ± 0,9 anos. Expansão rápida do palato (ERP) foi usada na maxila no início do uso da PLA. Usando as radiografias panorâmicas, a impacção dos segundos molares inferiores foi avaliada relativamente à posição dos primeiros molares mandibulares. Os movimentos horizontais e verticais dos primeiros e segundos molares inferiores foram avaliados com base em sobreposições de estruturas estáveis da arcada inferior por meio das radiografias laterais. RESULTADOS: oito (11,9%) pacientes apresentaram impacção dos segundos molares mandibulares ao final do tratamento com PLA; dois pacientes tiveram de recorrer à intervenção cirúrgica para a correção da impacção, cinco tiveram a correção da impacção usando apenas espaçadores e um apresentou autocorreção da impacção. A coroa e o ápice do primeiro molar inferior migraram 1.3mm e 2,.3mm, respectivamente, para mesial. O segundo molar não mostrou movimento horizontal significativo. ...

ABSTRACT

A impacção de incisivos superiores na fase de dentição mista, além de ser um desafio clínico, é uma má oclusão que preocupa os pais e as crianças, haja vista que afeta a estética do sorriso. Nesses casos, o diagnóstico precoce e o tratamento adequado são importantes para a melhor resolução do problema, tanto do ponto de vista funcional quanto psicológico. Um dos fatores etiológicos da impacção dentária é a presença de odontoma no trajeto de erupção do dente permanente. O tratamento ortodôntico-cirúrgico dessa má oclusão promove a erupção, posicionamento e estabilização do dente retido, além da remoção da patologia. Dessa maneira, o objetivo do presente estudo é apresentar um relato de caso clínico da remoção cirúrgica de odontoma e tracionamento do incisivo retido, com a utilização de aparelho ortodôntico removível. O aparelho foi utilizado de início para proporcionar abertura de espaço necessária à erupção do dente retido, sendo, depois, utilizado para tracioná-lo e posicioná-lo adequadamente na arcada. Os procedimentos adotados mostraram-se uma alternativa eficiente para o tratamento de dentes impactados, além de apresentarem baixo custo e boa aplicabilidade.

ABSTRACT

Los odontomas son entidades odontogénicas mixtas, compuestas por una mezcla de células odontogénicas epiteliales y mesenquimatosas diferenciadas. Por lo inusual del hecho el objetivo de nuestro trabajo fue presentar un caso de asociación de impactación dentaria por un odontoma con la alteración de la fórmula dental. Se trata de un paciente masculino de 26 años, que acudió a la consulta externa de Cirugía Maxilofacial refiriendo dolor. Al examen físico se detectó asimetría facial por aumento de volumen duro elástico del tercio facial inferior derecho. Al examen físico bucal se observó persistencia del 65 y 85, ausencia clínica del 15, 47 y 48 con expansión de las corticales vestibular y lingual en región mandibular posterior derecha (región molar y retromolar) y presencia de una apertura en la mucosa de aproximadamente 8 mm por distal del 46, en la cima del reborde alveolar, de forma redondeada. En el estudio ortopantomográfico se visualizó una imagen radiopaca irregular en sus bordes, de 3 cm, asociada a la oligodoncia del 48 e impactación del 47, por lo que se decidió realizar la exéresis quirúrgica de la lesión conjuntamente con el 47, indicándose estudio histopatológico que confirmó la presencia de un odontoma complejo con áreas de tejido blando periférico que mostraban inflamación crónica. El paciente se mantiene bajo seguimiento clínico e imagenológico en su tercer mes postoperatorio. El objetivo de nuestro trabajo fue presentar un caso de asociación de impactación dentaria por un odontoma con la alteración de la fórmula dental(AU)


The mixed odontogenic odontomas are entities composed of a mixture of differentiated odontogenic epithelial and mesenchymal cells. The objective of this paper was to presente an unusual case of association of dental impaction caused by odontoma and altered dental formula. A male patient aged 26 years, who felt pain, attended the outpatient Oral and Maxillofacial Surgery service. The physical examination found facial asymmetry with facial hard elastic augmentation in the right facial lower third. The Intraoral physical examination showed persistence of oral 65th and 85th , clinical absence of 15th , 47th and 48th with expansion of the vestibular and lingual cortices in the right posterior mandibular area (retromolar and molar regions) and presence of rounded mucosal opening about 8 mm distal to the 46th , on top of the alveolar ridge. In the orthopantomographic study, a ± 3cm radiopaque image with irregular edges, associated with oligodontia of the 48th and impaction of the 47th , were observed. It was decided to surgically remove the lesion together with the 47th and to indicate histopathological study. It was confirmed that the patient had a complex odontoma with peripheral soft tissue areas that showed chronic inflammation. The patient is still followed-up from the clinical and imaging viewpoints after three months of surgery(AU)

ABSTRACT

Crown dilaceration of permanent teeth occurs due to the non-axial displacement of the already formed hard tissue portion of the developing crown at an angle to their longitudinal axis due to trauma to the primary predecessors. This is a rare condition, representing only 3% of the total of injuries to developing teeth and usually occurs in permanent maxillary incisors because of the close proximity of their tooth germs to the primary incisors, which are more susceptible to trauma. This alteration frequently results from the intrusion of a primary tooth when the child is around 2 years of age, at which time half of the crown of the permanent successor is already formed. Teeth with dilacerated crowns may either erupt with buccal or lingual displacement or remain impacted. The treatment may involve endodontic, orthodontic, restorative and prosthetic procedures. This paper reports the restorative treatment proposed to reestablish the esthetics and function of the affected teeth in three cases of crown dilaceration in permanent maxillary incisors after trauma to their primary predecessors.

ABSTRACT

Reactive hyperplasias comprise a group of fibrous connective tissue lesions that commonly occur in oral mucosa secondary to injury. Peripheral fibroma is also a type of reactive hyperplasia. Peripheral fibroma is a reactive hyperplastic mass that occurs on the gingiva and is derived from connective tissue of the submucosa or periodontal ligament. It may occur at any age, although it does have a predilection for young adults. Females develop these lesions more commonly than do males. Here, we are presenting a case report of a child who is 6 years old and presented to us with a swelling in the lower anterior region which was providing discomfort to the child and also was obstructing the eruption pathway of the permanent central incisor in the region. The lesion was surgically excised.

ABSTRACT

Submersão, infraoclusão e impacção são termos utilizados para definir quando um dente se encontra aquém do plano oclusal, o que pode ser observado em diferentes graus. Na dentição decídua, essa anomalia acomete com mais frequência os segundos molares e a anquilose dentoalveolar é a etiologia mais aceita. Os dentes submersos impactados são fatores locais desencadeantes de má oclusão e, portanto, torna-se importante o diagnóstico precoce a fim de se evitarem danos no desenvolvimento normal da oclusão. A conduta clínica é definida de acordo com as características de cada caso e varia de um tratamento mais conservador ao mais radical, como as exodontias dos dentes envolvidos. Este trabalho tem como objetivo relatar o caso clínico de um paciente com submersão severa dos segundos molares decíduos, sendo que um dos molares em total submersão se encontrava com suspeita de lesão cariosa.

ABSTRACT

Canines contribute significantly to the esthetic and chewing functions. Orthodontists should diagnose canine ectopic eruption early, trying to prevent retention of these teeth. Its multifactorial etiology involves general and local factors and the correct diagnosis depends on clinic, radiographic and/or tomographic exams. Several therapeutic procedures depend on factors such as relationship between canine and adjacent structures, possibility of orthodontic movement and patient age. Orthodontic and surgical treatment with canine traction is very much effective, with time of treatment being shorter than in patients under the age of 25.

ABSTRACT

A localização intraóssea de um incisivo central superior, e o consequente atraso de sua irrupção, é um problema que afeta a autoestima das crianças. além disso, a falta de função mastigatória localizada, associada à migração dos dentes vizinhos, revela a importância do tratamento interceptivo nesses casos. A escolha da liga de beta-tirânio para o tratamento do incisivo foi fundamental na fórmula de Bustone (1981): rigidez do aparelho = rigidez do fio X desenho do aparelho. A combinação do módulo de elasticidade dessa liga ortodôntica com a configuração das alças de nivelamento permitiu a aplicação de forças leves e controle do movimento extrusivo.

ABSTRACT

La retención de los caninos superiores permanentes se encuentra asociada tanto a causas genéticas como nutricionales y locales. A partir de estudios radiográficos en niños, Haavikko, 1974, calculó la mediana del grado de calcificación de cada pieza dentaria según la edad. El objetivo de este estudio fue establecer asociaciones entre ciertas variables radiográficas respecto al germen de los caninos superiores y al estado nutricional de una población escolar. Se trabajó con 33 niños de edad cronológica entre 3 y 9 años de una población escolar rural. Se clasificaron los niños en los grupos desnutrido, control y sobrepeso. Para el estudio radiográfico se aplicó una técnica sistematizada utilizando un equipo radiográfico DSJ de 70kV con 8 mA y películas intraorales Insight (E F speed; Eastman Kodak, Rochester, NY). De los 66 estudios radiográficos obtenidos se escanearon las imágenes. Con el programa Image tool para Windows se midieron: a) distancia de cúspide de canino a sutura intermaxilar b) ángulo externo formado entre el eje del canino y el plano que corta la sutura intermaxilar en forma perpendicular c) grado de calcificación d) presencia de dientes supernumerarios. Los resultados fueron: a) Para la variable distancia no existen diferencias estadísticamente significativas entre los grupos desnutrido y control (p>0,05), aunque existen diferencias (p<0,001) entre los grupos control y sobrepeso; b) No existen diferencias significativas entre los estados nutricionales para la variable ángulo; c) Para la relación entre la edad cronológica con respecto a la edad dental calculada a través del grado de calcificación, se observaron diferencias significativas entre los grupos desnutrido y sobrepeso (p<0,01). Tanto la distancia del germen del canino como su grado de calcificación varían en pacientes con trastornos nutricionales por lo que sería de utilidad la aplicación de un estudio radiográfico a edad escolar para detectar anomalías dentarias.

ABSTRACT

Objetivos: Orientar os cirurgiões-dentistas a detectar a retenção dos caninos precocemente e de maneira simples, assim como apresentar as várias formas de tratamento frente a este problema, frisando a cirurgia para o tracionamento ortodôntico que visa trazer o canino retido para a posição correta no arco dentário. Este trabalho consiste na revisão de literatura sobre a retenção de caninos superiores, abordando seu desenvolvimento, sua incidência, etiologia, conseqüências, diagnóstico e as variadas modalidades terapêuticas e suas complicações. Conclusão: O diagnóstico precoce e a conduta preventiva são essenciais para diminuir a incidência de complicações e facilitar o tratamento dos caninos superiores impactados. O tratamento multidisciplinar é mandatório quando se opta pelo tracionamento, para que seja bem planejado e que seja escolhida a melhor técnica para cada caso. O tracionamento a campo fechado é a técnica mais utilizada por apresentar maior número de vantagens.


Objectives: We propose a guideline to help dental surgeon to early diagnosis a canine impaction, emphasizing the orthodontics traction surgery. After this review article concerning many choices of therapy for this disease, we also describe canines impaction, canine development, incidence of impaction, etiology, prognosis, diagnosis and most common surgical techniques and possible complications. Conclusions: Early diagnosis and preventive management are essentials tools to reduce complications, allowing treatment of upper canine impacted. A multidisciplinary treatment is mandatory, when choosing the orthodontic traction in order to have a well planned procedure and select the best surgical technique for each case. The closed eruption technique is prefered because it has more advantages.

ABSTRACT

O presente artigo ilustra a regulação de um canino inferior direito por tracionamento ortodôntico realizado com mecanoterapia fixa. Embora a impactação de caninos seja frequentemente observada no arco superior, a impactação dos caninos inferiores também pode ocorrer pela posição anômala do germe dentário, pela deficiência de espaço ou por obstáculos patológicos ou mecânicos. No presente caso clínico, a provável etiologia da impactação do canino inferior foi um obstáculo mecânico, representado por parafuso utilizado na fixação da miniplaca após cirurgia para redução de fratura mandibular.
