MAXILLARY expansion ,MALOCCLUSION - Abstract
Objective: To assess the short‐ and long‐term dentoskeletal effects of early Class III treatment with rapid maxillary expansion and facemask (RME/FM) followed by fixed appliances. Materials and Methods: A total of 44 patients (27 females, 17 males) treated consecutively with RME/FM were included from the archives of 3 centres. Three lateral cephalograms were available: T0 (before the start of RME/FM therapy, mean age 8.1 ± 1.8 years), T1 (immediately after RME/FM, mean age 9.8 ± 1.6 years), and T2 (long‐term observation, mean age 19.5 ± 1.6 years). A control group of 17 untreated Class III subjects (12 females and 5 males) also was selected. Between‐group statistical comparisons were performed with ANCOVA. Results: No statistically significant differences for any of the cephalometric variables were found at T0. In the short term, the treated group showed significant improvements in ANB (+2.9°), Wits appraisal (+2.7 mm), SNA (+1.8°) and SNB (−1.1°). A significant closure of CoGoMe angle (−1.3°) associated with smaller increments along Co‐Gn (−2.4 mm) also was found together with a significant increase in intermaxillary divergence (+1.3°). In the long‐term, significant improvements in ANB (+2.6°), Wits appraisal (+2.7 mm) and SNB (−1.7°) were recorded together with a significant closure of the CoGoMe angle (−2.9°). No significant long‐term changes in vertical skeletal relationships were found. Conclusions: RME/FM therapy was effective in improving Class III dentoskeletal relationships in the short term. These changes remained stable in the long‐term due mainly to favourable mandibular changes. [ABSTRACT FROM AUTHOR]

Introduction: There is currently no consensus in the literature whether the aetiology of a Class II subdivision is dental, skeletal or both. The aim of this study was to identify and quantify skeletal and dental asymmetries in Class II subdivision malocclusions. Methods: CBCTs from 33 Class II subdivision malocclusion patients were used to construct 3D volumetric label maps. Eighteen landmarks were identified. The original scan and associated 3D volumetric label map were mirrored. Registration of the original and mirrored images relative to the anterior cranial base, maxilla and mandible were performed. Surface models were generated, and 3D differences were quantified. Statistical analysis was performed. Results: Anterior cranial base registration showed significant differences for fossa vertical difference, fossa roll, mandibular yaw, mandibular lateral displacement and lower midline displacement. Regional registrations showed significant differences for antero‐posterior (A‐P) mandibular length, maxillary roll, A‐P maxillary first molar position, maxillary first molar yaw and maxillary first molar roll. Class II subdivision patients also show an asymmetric mandibular length as well as an asymmetric gonial angle. Moderate correlations were found between the A‐P molar relationship and fossa A‐P difference, mandibular first molar A‐P difference, maxillary first molar A‐P difference and maxillary first molar yaw. Conclusions: This study suggests that Class II subdivisions can result from both significant skeletal and dental factors. Skeletal factors include a shorter mandible as well as posterior and higher displacement of the fossa on the Class II side, resulting in mandibular yaw. Dental factors include maxillary and mandibular first molar antero‐posterior asymmetry. [ABSTRACT FROM AUTHOR]

The aim of this retrospective cross-sectional investigation was to perform a 3D analysis of craniofacial morphology of patients with unilateral cleft lip and palate (UCLP) at two stages of skeletal maturation. Cone-beam computed tomography (CBCT) scans of 52 UCLP patients (34 prepubertal; 18 pubertal) were collected from an outpatient referral center for the treatment of craniofacial deformities. In total 15 multiplanar craniofacial landmarks were identified, 3D virtual surface models were created, and 13 variables were measured to assess the 3D Euclidean distances between landmarks and spatial position of the landmarks in the projected X, Y and Z components. Maxillary and mandibular pitch (clockwise, counterclockwise) rotation relative to the cranial base was also evaluated. The significance level was set at 5%. Maxillary retrusion value relative to the cranial base was higher and statistically significant g reater (p = 0.028) in pubertal (SNA, 7 7.4° ± 6.2; N-ANS Y, 3.3 mm ± 3.1) than in prepubertal patients (SNA 81.0° ± 5.2; N-ANS Y, 5.8 mm ± 2.7). The posterior cranial base length (S-Ba Y) w as s ignificantly l onger (p = 0 .013) in pubertal (20.7 mm ± 3 .4) than in prepubertal patients (18.4 mm ± 2.7). The upper facial height (N-ANS Z) was significantly greater (p = 0.01) in pubertal (46.9 mm ± 4.5) than in prepubertal patients (43.4 mm ± 3.0). Prepubertal and pubertal UCLP patients presented distinct patterns of craniofacial morphology, mainly in the sagittal component of the maxilla and in the posterior cranial base length. Pubertal patients had greater maxillary retrusion and posterior cranial base length. [ABSTRACT FROM AUTHOR]

OBJECTIVES: To determine the three-dimensional changes of the nasal septum (NS), alveolar width, alveolar cleft volume, and maxillary basal bone following rapid maxillary expansion (RME) in consecutive patients with unilateral cleft lip and palate (UCLP). MATERIALS AND METHODS: A retrospective investigation was conducted based on the analysis of cone-beam computed tomography (CBCT) data of 40 consecutive patients with UCLP (mean age 11.1 ± 2.2 years). Scans were acquired prior to RME (T0) and after removal of the expander (T1) before graft surgery. A three-dimensional analysis of the effects of RME on the nasal septum, alveolar width, alveolar cleft volume, and maxillary basal bone was performed. RESULTS: No changes in the NS deviation were observed following RME (P > .05). Significant increases of the alveolar transverse dimension were found in the anterior (14.2%; P < .001) and posterior (7.7%; P < .001) regions as well as in the volume of the alveolar cleft (19.6%; P < .001). No changes in the basal bone dimensions and morphology were observed (P > .05). CONCLUSIONS: Following RME, no changes were observed in the NS and maxillary basal bones of patients with UCLP despite the significant gain in the anterior and posterior alveolar width and the increase of the alveolar cleft defect. Clinicians should be aware that maxillary changes following RME in patients with UCLP are restricted to the dentoalveolar region.

Carotid stenosis usually results from the accumulation of atherosclerotic plaque in the carotid artery wall and is an important risk factor for ischemic cerebral vascular accident (CVA). This study describes the importance of diagnostic imaging exams used in dentistry for the early identification of atheroma plaques in the extracranial and intracranial internal carotid artery. A male patient was referred to a radiology clinic to perform panoramic radiography (PR) and a cone beam computed tomography (CBCT) to develop treatment plan options. In the PR and CBCT a radiopaque image, suggestive of atheroma in the extracranial internal carotid artery, was observed on the right side. The diagnosis was confirmed by color DOPPLER ultrasonography. In the CBCT, the presence of calcifications in the intracranial internal carotid artery was also observed. Diagnostic imaging exams used in dentistry allow the identification of asymptomatic individuals, facilitating early intervention and consequent reduction in the risk of ischemic CVA. RESUMEN: La estenosis carotídea generalmente es consecuencia de la acumulación de placa aterosclerótica en la pared de la arteria carótida y es un factor de riesgo importante para el accidente cerebral vascular (ACV) isquémico. Este estudio describe la importancia de los exámenes de diagnóstico por imágenes utilizados en odontología para la identificación precoz de placas de ateroma en la arteria carótida interna, a nivel extracraneal e intracraneal. Un paciente masculino fue remitido a una clínica de radiología para realizar una radiografía panorámica (RP) y tomografía computarizada de haz cónico (TCHC) para analizar opciones de tratamiento. En el RP y TCHC se observó una imagen radiopaca, sugestiva de ateroma en la arteria carótida, extracraneal, en el lado derecho. El diagnóstico fue confirmado por ultrasonido DOPPLER color carotídeo. En el TCHC, también se observó la presencia de calcificaciones en la arteria carótida interna, intracraneal. Los exámenes de imagenología diagnóstica utilizados en odontología permiten la identificación de individuos asintomáticos, lo que facilita la intervención temprana y la consiguiente reducción en el riesgo de ACV isquémico.

Objectives: The aim of this short-term double-blind, parallel, randomized clinical trial was to compare bone augmentation grafting with 100% autogenous bone (AB) or 50% deproteinized bovine bone matrix (DBBM)/ 50% autogenous bone (BOAB) using a guided bone regeneration procedure, the fence technique, in a two-stage implant placement. Material and methods: Partially edentulous patients with extensive three-dimensional osseous defects were included in this study. The main outcome measure was the differences in bone volume from pre-surgery (T1) to 6 months post-surgery (T2). Bone height, chair-time, pain, functional limitation, and complications were also assessed. Results: Fifteen patients were allocated to the AB group and 15 patients to the BOAB group. The difference in bone volume from T1 to T2 was 648 mm3 for the AB group and 869mm³ for the BOAB group (difference between groups 221 mm³, 95% CI from -363 to 804, p = .442). The surgery pain VAS was 1.6 for the AB group and 2.3 for the BOAB group (difference between groups 0.8, 95% CI from 0.0 to 1.5, p = .045 favoring the AB group). The height difference in bone from T1 to T2 was 2.2 mm for the AB group and 3.7 mm for the BOAB group (difference between groups 1.5mm, 95% CI from 0.1 to 2.9, p = .038 favoring the BOAB group). For complications, chairtime, post-surgery pain, and functional limitation, there were no differences between AB and BOAB. Conclusions: No significant differences, except for surgery pain VAS and difference in bone height, were observed in this trial comparing grafting with AB or BOAB. [ABSTRACT FROM AUTHOR]

Aim To develop and validate a prediction model to forecast long-term stability of early treatment with rapid maxillary expansion (RME) and facemask (FM) in a large sample of Class III growing patients. Methods The Brazilian Group (BG) consisted of 73 consecutively treated Caucasian Class III patients (41 females and 32 males). Mean age at T0 (before treatment) was 7.1 ± 1.6 years, while mean age at T1 (long-term follow-up) was 21.8 ± 3.2 years. The Italian Group (IG, validation cohort) comprised 28 consecutively treated Caucasian Class III patients (14 females and 14 males, mean age at T0 9.0 ± 1.3 years and mean age at T1 18.2 ± 1.4 years). Cephalometric analysis was performed on lateral cephalograms at T0. Gender and cephalometric variables, chronologic age, and dentition phase at T0 were used as predictors for long-term unsuccessful treatment at T1. All predictors for unsuccessful treatment in the BG were subjected to bivariate logistic regression. Only those statistically significant predictors in the bivariate logistic regression entered mixed stepwise logistic regression with P = 0.05 to enter and to leave. The validity of the prediction model derived from the BG was then tested on the IG. Results The prediction model consisted of only one cephalometric variable: the angle between the Condylar Axis and the Mandibular Plane (CondAx–MP) (odds ratio: 1.52, 95% confidence interval: 1.25–1.85, P < 0.0001). Unsuccessful treatment at T1 was predicted for values of CondAx–MP at T0 greater than the cut-off value of 147.8 degrees. BG patients predicted incorrectly were 3 out of 22 for the unsuccessful cases and 1 out of 51 for the successful cases. Therefore, accuracy was 0.95, sensitivity 0.86, specificity 0.98, and positive and negative predictive values were 0.95 and 0.94. When the predictive model was applied on IG, all five unsuccessful cases were predicted correctly, while only 1 out of 23 successful patients was predicted incorrectly. Conclusion CondAx-ML was identified as a reliable predictor for long-term stability of early Class III treatment with RME and FM. [ABSTRACT FROM AUTHOR]

Article Subject - Abstract
The current concept for effective and efficient treatment of skeletal Class II malocclusion prescribes that interceptive approach should be delivered during the pubertal growth stage. However, psychosocial issues and a greater risk of dental trauma are also factors that should be addressed when considering early Class II therapy. This paper reports a case of a patient that sought orthodontic treatment due to aesthetic discomfort with the incisors’ protrusion. Two previous treatments failed because patient’s collaboration with removable appliances was inadequate. Given his history of no collaboration and because the patient was in the prepubertal stage, it was decided to try a different approach in the third attempt of treatment. Traumatic injury protective devices were used during the prepubertal stage and followed by Herbst appliance and fixed multibrackets therapy during the pubertal stage, resulting in an adequate outcome and long-term stability.

Baseado nos grandes benefícios que a utilização das imagens digitais pode proporcionar a Odontologia, o objetivo deste trabalho foi comparar a qualidade de quatro métodos de visualização de imagens em Odontologia. Foram selecionados quatro slides 35 mm de pacientes da Faculdade de Odontologia da Pontifícia Universidade Católica de Minas Gerais. Os diapositivos foram digitalizados por quatro recursos e, posteriormente, as imagens foram processadas para serem visualizadas por quatro métodos: (1) revelação digital em papel fotográfico; (2) impressão em papel fotográfico com impressora jato de tinta amadora; (3) tela de computador e (4) projetor de multimídia. Posteriormente, essas imagens foram submetidas à avaliação de quinze indivíduos, sorteados aleatoriamente, divididos em cinco grupos. Para cada imagem avaliada, os examinadores julgavam se estas eram aceitáveis ou não do ponto de vista clínico e científico e analisavam quatro variáveis: (a) brilho e contraste; (b) definição e nitidez; (c) fidelidade e reprodução de cores e (d) nota geral, aferindo uma nota de zero a cinco para cada quesito. Encontrou-se um alto grau de aceitabilidade de 82,9% das imagens sem diferença estatisticamente significante entre elas. Foi identificado que o grupo de imagens impressas em impressora amadora em todos os quesitos posicionou-se no grupo com valores inferiores, enquanto o grupo de imagens visualizadas na tela de computador apresentou resultados superiores na maioria dos quesitos (p < 0,05). Concluiu-se que os métodos de visualização de imagens digitais pesquisados apresentam-se dentro de padrões plenamente aplicáveis para serem utilizados em Odontologia enquanto o método da impressora amadora obteve o pior desempenho

Um dos grandes benefícios que a evolução tecnológica proporcionou à Ortodontia foi a utilização das imagens digitais. O uso dessa nova tecnologia em Odontologia, e especificamente em Ortodontia, aliada à introdução da Fotografia Digital, permite aos profissionais desta área utilizar recursos, antes inimagináveis, facilitando a elaboração do diagnóstico ortodôntico, auxiliando a comunicação entre profissionais, bem como com os pacientes, além de ilustrar comunicações científicas, em conferências, cursos e publicações, sendo uma excelente ferramenta para o ensino e pesquisa. Com o objetivo de lançar mão dessa nova tecnologia, o ortodontista pode obter imagens digitais por meio da digitalização da documentação ortodôntica convencional composta basicamente de fotografias analógicas (em papel ou em slide), modelos de estudo e radiografias ou pela obtenção de imagens digitais com câmeras fotográficas digitais. Desta forma, o objetivo desse trabalho é esclarecer alguns conceitos básicos relacionados às imagens digitais e tentar responder às perguntas mais freqüentes em relação ao tema: Como digitalizar as minhas documentações ortodônticas com um scanner? Como obter imagens digitais com uma câmera fotográfica digital? Que tipo de resolução em DPI (dots per inch, ou pontos por polegada) ou em Megapixel (MP), tamanho e formato de arquivo devo utilizar para as minhas necessidades ortodônticas de rotina? A obtenção de imagens com finalidade apenas de visualização no monitor do computador é diferenciada daquela para outros fins, como impressão de relatórios, banners ou apresentações com recurso de multimídia? E por fim, qual resolução deve ser utilizada para obter imagens digitais que serão encaminhadas para publicações científicas? The use of digital images is one of the fastest-growing new technologies in the contemporary society. The use of this new technology in Dentistry, and especially in Orthodontics, associated with the introduction of "Digital Photography" allows the clinician to acquire things ever imagined, facilitating the orthodontic diagnosis, improving the doctor/doctor and doctor/patient communication, illustrating scientific communications in speeches, conferences and articles, being thereby, an excellent tool for teaching and research. In order to take advantages of this new field, the orthodontic records including photographs, models and radiographs must be converted into digital images. Therefore, as we enter into the "digital world", the aim of this paper is to clarify some basic concepts regarding the digital imaging and try to answer the must common questions about this topic: How to convert digitally the orthodontic records with a scanner? How to acquire digital images with a digital camera? At what resolution in DPI (dot per inch) or in Megapixel (MP), file size and file format should the images have to fulfill my usual demands? At what resolution should the images have in order to be used in the computer monitor? And what resolution should the images be imported into presentation programs in order to be displayed in multimedia projectors? And at last, how to easily acquire digital images that will be used in scientific papers?

Tese (Doutorado) - Pontifícia Universidade Católica de Minas Gerais, Programa de Pós-Graduação em Odontologia. Bibliografia: f. 93-96 O objetivo neste estudo retrospectivo foi testar e avaliar a região do canal nasopalatino (CNP) e sutura palatina mediana (SPM), como referência para as sobreposições regionais volumétricas de maxila, em estudos que utilizam a Tomografia Computadorizada de Feixe Cônico (TCFC). Adicionalmente objetiva-se descrever as alterações dentoesqueletais maxilares em pacientes com má oclusão Classe II de Angle, tratados com o aparelho extraoral de tração combinada (AETC). TCFC e modelos de gesso, obtidos antes e após o tratamento, foram usados para a comparação entre o método padrão-ouro (superposição em rugas palatinas) e o método avaliado (superposição no CNP e SPM). A metodologia foi realizada através de software de livre acesso (ITK-SNAP 2.4® e 3DSlicer 4.8®). Os modelos de gesso foram digitalizados e sobrepostos na respectiva TCFC, através do contorno das coroas dentárias. Utilizou-se os tons de cinza dos voxel das TCFC, na região do CNP e SPM para superpor as tomografias. A matriz matemática, gerada pelo software para o registro das TCFC, foi aplicada aos modelos. O registro em ruga foi feito na superfície dos modelos e a matriz deste registro aplicada a TCFC. Mensurações das alterações dos dentes 16, 11 e 26, nos três eixos do espaço (X, Y e Z) foram realizadas nas TCFC, para as duas modalidades de registros regionais na maxila. Compararam-se também, os mapas de códigos de cores das alterações de cada paciente, para os dois registros. Para a descrição das alterações dentoesqueletais, após o tratamento com o AETC, as TCFC foram registradas em base do crânio (BC) e no CNP e SPM. Mensurações dos deslocamentos dos dentes 16, 11 e 26; além dos pontos cefalométricos ponto A, espinha nasal anterior, espinha nasal posterior e forame incisivo foram efetuadas. Comparando o registro nas rugas palatinas com o em CNP e SPM, os valores medidos na região de molares mostraram pequenas divergências, sem diferenças estatisticamente significativas (p > 0,05). Apenas o deslocamento lateral do dente 11 apresentou diferença significativa (p < 0,05) entre os métodos. Os mapas de códigos de cores do registro no CNP e SPM apresentaram uma concordância na região das rugas. Maior variação de cores pode ser observada nas laterais do palato. Nas alterações dentoesqueletais, após o uso do AETC, a distalização do 16 foi de 2.17 mm para o registro no CNP e SPM e de 1.75 mm para BC. A extrusão dos molares foi resultante da movimentação esqueletal e dentária, com valores menores para a extrusão dentária isolada e maior em relação à base craniana (1.03 mm BC e 0,39 mm CNP e SPM). As referências ósseas, exceto o ponto A, demostraram recuo. O registro por voxel do CNP e SPM é confiável e trouxe resultados estatisticamente iguais ao padrão ouro, quando se analisou o controle vertical e antero posterior de alguns dentes. O registro no CNP e SPM pode ser utilizado como uma alternativa para o registro regional de maxila com TCFC. As mudanças dentárias e esqueléticas, observadas após o uso do AETC, corroboram dados prévios desta abordagem terapêutica. Palavras-chave: Registro da relação maxilomandibular. Software. Má oclusão de Angle Classe II. Aparelhos de tração extrabucal. Ortodontia interceptora. Imagem tridimensional. This retrospective study aimed to test and evaluate the nasopalatine canal (NPC) and the median palatine suture (MPS), as a reference for the volumetric maxillary superimposition, in studies that use the Cone Beam Computed Tomography (CBCT). In addition, the objective of this research was to describe the maxillary dentoskeletal changes in patients with Angle Class II malocclusion treated with combination headgear. Pre treatment and post treatment CBCT and plaster models were used to compare the gold standard method (superimposition on the palatal rugae) and the alternative method (superimposition on the NPC and MPS). The methodology used open access software (ITK-SNAP 2.4® and 3DSlicer 4.8®). The plaster models were digitalized and overlaid on respective CBCT, using the contour of the dental crowns. The tons of gray densities of the CBCT voxels, in the NPC and MPS region were used to superimpose the scans. The mathematical matrix generated by the software for the voxel-based registration at NPC and MPS was applied to the models. The registration in palatal rugae was made through the surface of the models, and the matrix of this registration was applied to CBCT. Measurements of positioning crown changes of teeth 3, 8 and 14, in the three axes of space (X, Y and Z), were performed in the CBCT, for the two types of regional maxillary registration. The color-coded maps of the changes were also compared for each patient, using the two types of records. For the description of the dentoskeletal changes after treatment with combination headgear, the CBCT were registered in the cranial base (CB) and in the NPC and MPS. Measurements of teeth 3, 8 and 14 displacements, in addition to cephalometric landmarks (point A, anterior nasal spine, posterior nasal spine and incisive foramen), were performed. Comparing the palatal rugae registration with NPC and MPS, the measured values in the molar region showed small divergences, without statistically substantial differences (p > 0.05). Only the lateral displacement of tooth 8 showed a significant difference (p < 0.05) between the methods. The color maps of the NPC and MPS record showed an agreement in the palatal rugae region. Greater variation of colors can be seen on the palate sides. In dentoskeletal changes after the use of combination headgear, the distalization of the right molar was 2.17 mm for the NPC and MPS registration, and 1.75 mm for CB. The molar extrusion resulted from skeletal and dental movement, with lower values for isolated dental extrusion and higher when compared to the cranial base (1.03 mm BC and 0.39 mm NPC and MPS). Bone references, except point A, showed distalization. The voxel registration by NPC and MPS is reliable and brought results without statistically significant differences to the gold standard method when analyzing the vertical and anteroposterior displacements. The registration with NPC and MPS can be used as an alternative to the regional maxillary registration with CBCT. The dental and skeletal changes observed after the use of the headgear corroborate previous data on this therapeutic approach. Keywords: Jaw relation record. Software. Malocclusion, Angle Class II.

Dissertação (Mestrado) - Pontifícia Universidade Católica de Minas Gerais, Programa de Pós-Graduação em Odontologia Bibliografia: f. 65-66 O objetivo no presente estudo foi avaliar a validade e a confiabilidade de dois métodos de sobreposição (sobreposição usando pontos de referência e sobreposição usando regiões de interesse) de modelos digitais do arco dentário maxilar com software de livre acesso 3D Slicer. Modelos digitais tridimensionais (3D) do arco dentário maxilar de 16 crianças que não se submeteram a tratamento ortodôntico foram reorientados no espaço de forma padronizada, criando assim, 16 modelos clonados dos modelos originais com as mesmas características anatômicas, porém com diferente orientação espacial. Os modelos foram sobrepostos de forma automática pelo software, utilizando nove pontos de referência: os pontos mediais da segunda e terceira rugas de ambos os lados, o ponto médio entre os pontos laterais e mediais da terceira ruga, também em ambos os lados, e três pontos específicos na rafe palatina mediana: a) ponto na rafe palatina localizado 3 mm posterior ao ponto médio da terceira ruga mais posterior; b) 5 mm posterior a este último ponto na rafe palatina, e c) 5 mm posterior a este último ponto na rafe palatina. A validade dos dois métodos foi testada quantificando as diferenças observadas entres os modelos sobrepostos e os dois métodos foram comparados através do teste t de Student para amostras pareadas. A confiabilidade do método foi aferida avaliando-se o erro intraobservador através das repetições das sobreposições. A concordância intraobservador foi determinada pelo teste t de Student para amostras pareadas, onde os valores de P indicaram se havia significado estatístico entre as medidas realizadas pelo mesmo examinador. O Color Map dos modelos sobrepostos indicou uma grande diferença entre os modelos quando do uso de pontos de referencia para a superposição, invalidando este método. Todavia, a sobreposição usando as regiões de interesse apresentaram mínimas diferenças entre os modelos, com excelente concordância intraexaminador para as medidas avaliadas, sugerindo que este método de sobreposição é adequado. A sobreposição de modelos 3D digitais da arcada superior com software de livre acesso 3D Slicer mostrou-se válida e confiável quando o método de registro utilizou regiões de interesse. Palavras-chave: Sobreposição. Modelos digitais. Imagem tridimensional. Reprodutibilidade dos testes The aim of the present study was to evaluate the validity and reliability of two superimposition methods (superimposition using landmarks and superimposition using regions of interest) of digital maxillary models with open-access 3D Slicer software. Three-dimensional (3D) digital models of the maxillary dental arch of 16 children who did not undergo orthodontic treatment were reoriented in space in a standardized manner, thus creating 16 cloned models of the original models with the same anatomical characteristics, but with different spatial orientation. The models were automatically superimposed by the software using nine landmarks: the medial points of the second and third palatine rugae on both sides, midpoint between the lateral and medial points of the third ruga, also on both sides, and three. Specific points on the midpalatal raphe: a) Point on the palatal raphe located 3 mm posterior to the midpoint of the third most posterior ruga; b) 5 mm posterior to this last point in the palatal raphe, and c) 5 mm posterior to this last point in the palatal raphe. The validity of both methods was tested by quantifying the differences observed between the superimposed models and the two methods were compared using the Student's t test for paired samples. The reliability of the method was assessed by assessing the intraobserver error through repetition of the superimpositions. Intraobserver agreement was determined by Student's t test for paired samples, where P values indicated whether there was statistical significance between the measurements performed by the same examiner. The Color Map of the superimpositions models indicated a great difference between the models when using reference points for the superposition, invalidating this method. However, the superimposition using the regions of interest showed minimal differences between the models, with excellent intra-examiner agreement for the measures evaluated, suggesting that this superimposition method is appropriate. Superimposition of maxillary digital models with open access 3D Slicer software proved to be valid and reliable when the registration method used regions of interest. Keywords: Superposition.

- Abstract
Supernumerary tooth/teeth (ST) are a well recognized clinical phenomenon defined as teeth that are additional to the normal complement. The purpose of this report was to describe 3 patients who developed multiple sequential ST. All patients were boys between 8 and 12 years old without significant medical history. In 2 cases, the ST were discovered while investigating the nonexfoliation of primary teeth, whereas in the other they were an occasional finding on a radiograph taken for orthodontic purposes. All patients were kept under close follow-up ofter treatment. The 3 patients collectively developed a total of 17 ST with 9 found in a single patient, over a 5-year period. This article demonstrates the importance of clinical and radiographic follow-up of ST patients, regardless of age, family history, or systemic condition. [ABSTRACT FROM AUTHOR]

Dissertação (mestrado) - Pontifícia Universidade Católica de Minas Gerais, Programa de Pós-Graduação em Odontologia Bibliografia: f. 69-72 Resumo: A crescente busca por tratamentos ortodônticos com objetivo estético, o acirramento da competição mercadológica e a elevação do padrão de exigência por parte dos consumidores quanto à qualidade dos serviços prestados determinou a importância da observação e monitoramento pelos profissionais do desempenho da excelência no seu atendimento aos clientes. Estudos prévios, em diversas áreas do conhecimento, são concordantes que a percepção da qualidade dos serviços prestados potencialmente influencia várias atitudes e intenções comportamentais dos consumidores, porém pouco se sabe sobre este contexto na Ortodontia. Assim, os objetivos deste trabalho foram elaborar e testar um modelo de avaliação da Qualidade Percebida Global (QPG) por pais de pacientes em relação ao tratamento ortodôntico de seus filhos e verificar os impactos sobre a Satisfação, o Valor Percebido, a Comunicação Boca-a-Boca e a Propensão à Lealdade. Na primeira etapa (fase qualitativa) da metodologia, buscando identificar as variáveis atinentes à Qualidade Percebida a serem incluídas na fase quantitativa (segunda etapa), realizou-se a revisão de literatura e entrevistas com 12 pais de pacientes em tratamento ortodôntico e com cinco ortodontistas. Na segunda etapa, um levantamento descritivo do tipo Survey foi conduzido em um período de 3 semanas com base em um corte transversal único. Foi elaborado um questionário semi-estruturado composto por 72 variáveis quantitativas referentes à Qualidade Percebida e 14 às atitudes e intenções comportamentais. Para a mensuração das repostas, utilizou-se uma escala de concordância e discordância variando de 1 (discordo totalmente) a 5 pontos (concordo totalmente) e ainda a opção ?NS/NA? (não sei/não se aplica). A amostragem não probabilística por cotas foi eleita para a coleta de dados, sendo aplicados 321 questionários nas nove regionais administrativas de Belo Horizonte (Minas Gerais) em pais/responsáveis de pacientes abaixo de 18 anos de idade sob tratamento ortodôntico. As análises estatísticas descritivas resultaram em 11 fatores de QPG, sendo os que mais a explicam: Capacidade técnica do ortodontista (0,993**), Materiais utilizados pela clínica (0,978**), Organização administrativa (0,973**), Relacionamento ortodontista/paciente (0,955**) e Consultas - disponibilidade de horários e datas para agendamento (0,952**). Quatro dimensões integraram as atitudes e intenções comportamentais. Segundo a análise de Modelagem de Equações Estruturais, a QPG apresentou impactos diretos, positivos e significativos sobre a Satisfação (R2 = 74,5% e ? = 0,315**) e o Valor percebido (R2 = 54,7% e ? = 0,790**). O Valor Percebido também teve um impacto direto, positivo e significativo sobre a Satisfação (? = 0,600**) e demonstrou ser influenciado de maneira negativa sobre o Preço do tratamento (? = 0,149**). Já o Preço não apresentou impactos diretos e significativos sobre a Satisfação dos pais de pacientes (? = - 0,023NS). E a Satisfação, por sua vez, apresentou impactos positivos, diretos e significativos sobre a Comunicação Boca-a-Boca (R2 = 89,7% e ????0,947**) e a Propensão à Lealdade (R2 = 79,8% e ??= 0,893**). A QPG pelos pais de pacientes em relação aos tratamentos ortodônticos é um construto multidimensional composto por 11 fatores que apresenta impactos sobre suas atitudes e intenções comportamentais. Abstract: The growing demand for orthodontic treatments due to aesthetic purposes, the intensification of market competitiveness and the high standard of perception of consumer?s right by the patients in general determined the enormous importance for the observation and monitoring of the excellence of the orthodontic offices in the contemporary world under the perspectives of the patients. Previous studies, in different fields of knowledge, agreed that consumer?s perception of the service quality potentially influences several of their attitudes and behavioral intentions. However, little is known about this topic in Orthodontics. Thus, the aims of the current study were to elaborate and to test a Global Perceived Quality (GPQ) assessment model by patient?s parents regarding their children's orthodontic treatment, and to verify the impacts on Satisfaction, Perceived Value, Word-of-Mouth Communication and the Propensity to Loyalty. In the Phase 1 (qualitative stage) of the methodology it was collected data to formulate a descriptive Survey to be applied in Phase 2 (quantitative stage), including a literature review, and interviews with 12 patient?s parents undergoing orthodontic treatment, and with five orthodontists, and identifying the variables regarding Perceived Quality. In the Phase 2, the Survey was conducted along a 3 weeks period, based on a single cross-sectional design. The semi-structured questionnaire consisted of 72 quantitative variables related to Perceived Quality and 14 variables related to attitudes and behavioral intentions. It was used a scale of agreement and disagreement, ranging from 1 (strongly disagree) to 5 (strongly agree), and also the option ?NS / NA? (I don't know / it does not apply). It was used the non-probabilistic quota sampling method, and 321 questionnaires were in the nine administrative regions of Belo Horizonte (Minas Gerais). Parents or guardians of patients below 18 years of age under orthodontic treatment participated in this survey. Descriptive statistical analyzes resulted in 11 GPQ factors, and five were the most relevant: Orthodontist Technical Skills (0.993**), Materials used by the Clinic (0.978**), Administrative Organization (0.973**), Orthodontist Relationship with patients (0.955**) and Availability of scheduling consultations (0.952 **). Four dimensions integrated the attitudes and behavioral intentions. According to Structural Equation Modelling analyzes, the GPQ had direct, positive and significant impacts on Satisfaction (R2 = 74.5% and ??= 0.315**) and on Perceived Value (R2 = 54.7% and ? = 0.790**). Perceived Value also had a direct, positive and significant impact on Satisfaction (? = 0.600**), and it was negatively influenced by Treatment Price (?? = 0.149**). Price did not have direct and significant impacts on the satisfaction of patient?s parents (??= - 0.023NS). Satisfaction had positive, direct and significant impacts on Word-of-Mouth Communication (R2 = 89.7% and ???? 0.947 **) and Propensity to Loyalty (R2 = 79.8 % e ? = 0.893**). The GPQ by the patient?s parents regarding orthodontic treatments is a multidimensional construct composed of 11 factors that has impacts on their attitudes and behavioral intentions.

Microcefalia ,CIENCIAS DA SAUDE::ODONTOLOGIA [CNPQ] ,Má oclusão ,Dentição - Abstract
Coordenação de Aperfeiçoamento de Pessoal de Nível Superior (CAPES) Introdução: A microcefalia em um nascido vivo é definida como uma anomalia em que perímetro cefálico (PC) está abaixo do padrão de curvas apropriadas para idade e gênero. A etiologia pode envolver anormalidades genéticas, síndromes, distúrbios metabólicos, teratógenos, infecções pré-natal, perinatal e pós-natal. Porém, essa malformação tornouse muito mais prevalente com o surto recente do vírus Zika. Objetivos: Estudar o padrão de oclusão em bebês com microcefalia associada ao vírus Zika (MZV). Metodologia: O artigo 1 foi um estudo transversal que incluiu pacientes com diagnóstico de MZV (40) entre 30 e 36 meses e um grupo controle com bebês saudáveis (40), aleatoriamente selecionadas com as mesmas características sociodemográficas. A análise estatística utilizou análise descritiva, o teste qui-quadrado de Pearson e a regressão logística multivariada. O artigo 2 foi um relato de casos clínicos com infecção no segundo trimestre da gestação. O artigo 3 foi um relato de casos clínicos com infecção no primeiro trimestre da gestação. Resultados: Foi demonstrado uma prevalência significativamente maior de maloclusões em bebês MZV em comparação ao grupo controle (artigo 1). Pacientes com MZV possuíram maior probabilidade de apresentar irrupção tardia (p < 0,001), formato da arcada superior e inferior atrésico (p < 0,001), overjet acentuado (p < 0,001) e mordida cruzada posterior (p= 0,004) (artigo 1). Também foi demostrado ocorrência de irrupção tardia, hipodontia, tendência a crescimento vertical, perfil convexo, comprometimento do tônus muscular, incompetência de selamento labial, mordida aberta e desvio de linha média (artigos 2 e 3). Conclusões: Conclui-se que existe uma maior probabilidade de irrupção tardia e prevalência maior de maloclusões em bebês MZV, dentre elas o formato da arcada superior e inferior atrésico, overjet acentuado e mordida cruzada posterior. Comprometimento muscular também foi encontrado. Além disso, o período de infecção pelo vírus parece determinar a gravidade das características encontradas. Introduction: Microcephaly in a live birth is defined as an anomaly in which head circumference (HC) is below the standard for age and gender appropriate curves. The etiology may involve genetic abnormalities, syndromes, metabolic disorders, teratogens, prenatal, perinatal and postnatal infections. However, this malformation has become much more prevalent with the recent emergence of the Zika virus. Objectives: To determine the prevalence of malocclusion among infants with Zika virus-associated microcephaly (MZV) and to describe the most common malocclusion characteristics in this population (Article 1); to identify differences in univiteline twins with and without Zika virus-associated microcephaly infection during the second trimester of gestation (Article 2); to describe the dentoskeletal changes in two infants who were infected with the Zika virus during the first trimester of gestation (Article 3). Method: Article 1 was a cross-sectional study which included patients diagnosed with MZV (40) between 30 and 36 months and a comparison group with healthy babies (40), randomly selected with the same sociodemographic characteristics. The statistical analysis used descriptive analysis, Pearson’s chi-squared test and multivariate logistic regression. Articles 2 and 3 are case reports, one with infection in the second trimester of pregnancy and another in the first, respectively. Results: In article 1, a significantly higher prevalence of malocclusions in MZV infants was demonstrated in comparison to the control group (p

Dissertação (Mestrado) - Pontifícia Universidade Católica de Minas Gerais, Programa de Pós Graduação em Odontologia. Bibliografia: f. 57-59. O domínio do conhecimento sobre os padrões normais de crescimento e desenvolvimento dos arcos dentários é essencial para um correto diagnóstico e planejamento ortodôntico, assim como para alcançar satisfatória estabilidade pós-tratamento. As mudanças dimensionais dos arcos é um processo dinâmico, com alterações ocorrendo da infância até a idade adulta. Apesar da extensa literatura disponível sobre tais mudanças, existem poucas descrições específicas sobre a transição entre as fases de dentadura decídua para mista inicial, em crianças não tratadas e que apresentam oclusão normal. Dessa forma, o objetivo desse trabalho foi avaliar as mudanças dimensionais nos arcos dentários que ocorrem na transição entre as fases de dentadura decídua para mista inicial em crianças com normoclusão não tratadas ortodonticamente. A partir de uma amostra-mãe longitudinal, acompanhada por 15 anos, 85 pacientes com normoclusão, durante a fase de dentadura decídua foram selecionados. Após a aplicação dos critérios de exclusão e inclusão, uma amostra final composta por 29 crianças (17 meninas e 12 meninos), com idades média de 4,5 anos na avaliação inicial (T0 dentadura decídua) e 9,1 anos na avaliação final (T1 dentadura mista inicial) foi selecionada. Foram consideradas as mudanças ao longo do tempo nas seguintes variáveis: largura dos arcos (distância intercaninos e intermolares), comprimento dos arcos e perímetro dos arcos. Adicionalmente, avaliou-se as mudanças na profundidade do palato e na profundidade da Curva de Spee. As mensurações foram feitas por meio do software 3D SLICER, a partir da digitalização dos modelos de gesso. Foram avaliados os componentes X (látero-lateral), Y (ântero-posterior) e Z (supero-inferior), além das mudanças da distância 3D Euclidiana (3D). Observou-se entre T0 e T1 um significativo aumento da largura e do perímetro dos arcos dentários, bem como um aumento significante da profundidade do palato e da Curva de Spee (P < 0,001). Redução estatisticamente significante foi observada para o comprimento do arco inferior (P < 0,001), todavia no arco superior não foram observadas mudanças significativas (P > 0,05). Os segundos molares e caninos decíduos do lado direito mostraram-se estáveis posicionalmente nos aspectos ântero-posterior e supero-inferior em relação aos mesmos dentes do lado esquerdo. Dimorfismo sexual foi observado nesse estudo com meninos apresentando arcos superiores e inferiores mais largos na região dos segundos molares decíduos em T0. Em T1 essa diferença entre gêneros foi significativa apenas para o arco superior. Diante disso, concluímos que as crianças em normoclusão apresentam mudanças significativas dos arcos dentários na transição entre as fases de dentadura decídua a mista inicial.

The knowledge on dentofacial growth and development is essential for orthodontic diagnosis and planning, as well as to the achievement of posttreatment occlusal stability. The dimensional changes of the arches are a dynamic process, with variations from childhood to adulthood. Despite the extensive available literature on such changes, there are few specific descriptions of the transition between the stages of deciduous to early mixed dentition in untreated children with normal occlusion. The aim of this study was to analyze the dimensional changes of the dental arch from deciduous dentition to early mixed dentition in untreated normal occlusion children. From a longitudinal sample composed of 85 patients with normocclusion during deciduous dentition, a convenience sample composed of 29 children (17 girls and 12 boys) was selected after applying the inclusion criteria. At baseline (T0) the mean age was 4.5 years. In a second time-point evaluation (T1), the mean age of the children was 9.1 years. The changes between T0 and T1 of the following variables were considered: width of the arches (intercanine and intermolar distance), length of arches and perimeter of arches. In addition, the changes of the palatal depth and Curve of Spee were assessed. The measurements were made using 3DSlicer software, from the digitalization of plaster models. The X (right-left), Y (anterior-posterior) and Z (inferior-superior) multiplanar projections in the coordinate system views of the changes of the arches were analyzed, as well as the 3D Euclidean distance (3D). It was found a significant increase in the width of the dental arches between T0 and T1, as well as a significant increase in the depth of the palate and the Curve of Spee (P < 0.001). Statistically significant reduction was observed for the length of the lower arch measurements (P < 0.001), however it was not observed with significant changes of the maxillary arch length (P > 0.05). The second deciduous molars and deciduous canines on the right side were stable in the antero-posterior and inferior-superior aspects relative to their homologous of them other side. Sexual dimorphism was observed in this study with boys presenting greater maxillary and mandibular measurements in the region of deciduous second molars at T0. At T1, the difference between genders was significant only for the maxilla. Therefore, it was concluded that the children in normal occlusion present significant changes of the dental arches in the transition between the deciduous to the early mixed dentition phase.
