ABSTRACT

Introduction:The supply of public orthodontic services is still unable to meet the demand for treatment of malocclusions. The resources available are sometimes mismanaged and significant financial impacts contribute to limited access to the services. Objective:To carry out an integrative review regarding the access and financial impacts of public orthodontic service among the various health systems worldwide, considering social inequalities and the referral and counter-referral systems for services. Methodology:A survey was conducted using the BVS (Biblioteca Virtual em Saúde / Virtual Health Library), PubMed, and Cochrane databases, including articles available from 1970 to 2019, which elucidated the guiding question "How does access work and what are the financial impacts of the provision of orthodontic services in different public health systems worldwide?". Results:211 articles were found, of which 20 were analyzed. The chronological distribution was relatively uniform. The topic 'access to orthodontic services' was most frequently reported and there was a predominance of studies addressing the provision of treatment for children and adolescents. Conclusions:There are significant financial impacts and demographics have a strong influence on access to services. The provision of orthodontic treatments by the private sector predominates, preventive approaches are scarce, and an optimization in the use of available resources is necessary. Primary Care has much to contribute in increasing access, reducing costs, and making the referral / counter-referral system effective (AU).


Introdução:A oferta de serviços ortodônticos públicos ainda não consegue suprir a demanda de tratamento de má oclusões. Os recursos disponíveis, por vezes, mal alocados e os impactos financeiros significativos contribuem para a restrição do acesso aos serviços.Objetivo:Realizar uma revisão integrativa pertinente ao acesso e aos impactos financeiros da provisão ortodôntica pública nos diversos sistemas de saúde mundiais, sob a luz das iniquidades sociais e dos sistemas de referência e contrarreferência de serviços.Metodologia:Foi realizado um levantamento nas bases de dados BVS (Biblioteca Virtual em Saúde), PubMed e Cochrane Reviews, incluindo os artigos disponíveis no período de 1970 a 2019, que elucidavam a questão norteadora "Como se dá a provisão de serviços ortodônticos nos diversos sistemas públicos de saúde mundiais?".Resultados:Foram encontrados 211 registros, dos quais 20foram analisados. A distribuição temporal foi relativamente uniforme. A temática "acesso aos serviços ortodônticos" foi mais frequentemente relatada e houve um predomínio de estudos abordando a oferta de tratamentos a crianças e adolescentes. Conclusões:Há impactos financeiros significativos e os determinantes sociais exercem forte influência sobre o acesso aos serviços. Predomina a oferta de tratamentos ortodônticos pelo setor privado, abordagens preventivas são escassas e é necessária uma otimização no uso de recursos disponíveis. A Atenção Básica tem muito a contribuir para aumento do acesso, diminuição de custos e efetivação do sistema dereferência/contrarreferência dos serviços (AU).


Introducción: La provisión de servicios públicos de ortodoncia aún no puede satisfacer la demanda de tratamientos de maloclusión. Los recursos disponibles a veces están mal asignados y los impactos financieros significativos contribuyen a restringir el acceso a los servicios.Objetivo: Realizar una revisiónintegradora pertinente al acceso y los impactos económicos de la provisión pública de ortodoncia en los diferentes sistemas de salud a nivel mundial, a la luz de las inequidades sociales y los sistemas de derivación y contrarreferencia de servicios.Metodología: Se realizó una encuesta en las bases de datos de la BVS (Virtual Health Library), PubMed y Cochrane Reviews, incluidos los artículos disponibles desde 1970 hasta 2019, que dilucidó la pregunta orientadora "¿Cómo es la prestación de servicios de ortodoncia en los diferentes sistemas públicos?".Resultados: Se encontraron 211registros, de los cuales se analizaron 20.La distribución temporal fue relativamente uniforme. El tema "acceso a servicios de ortodoncia" fue el que se informó con mayor frecuencia y hubo un predominio de estudios que abordan la provisión de tratamientos a niños y adolescentes.Conclusiones: Hay impactos económicos significativos y los determinantes sociales tienen una fuerte influencia en el acceso a los servicios. Predomina la oferta de tratamientos de ortodoncia por parte del sector privado, los abordajes preventivos son escasos y es necesario optimizar el uso de los recursos disponibles. La Atención Primaria tiene mucho que contribuir para aumentar el acceso, reducir costos e implementar el sistema de derivación / contrarreferencia de servicios (AU).

ABSTRACT

Este trabajo de investigación tiene como finalidad comparar la inclinación del incisivo inferior pre y post-tratamiento en pacientes tratados ortodóncicamente con técnicas Roth y técnica Damon a los cuales no se les realizó exodoncias. El grupo de estudio estuvo conformado por 150 pacientes adultos con dentición permanente completa que han sido atendidos en el Círculo Argentino de Odontología. Para medir la inclinación se utilizó la fórmula de Tweed: ángulo IMPA, eje axial del incisivo inferior con el plano mandibular. Los valores tomados de los trazados pre y post-tratamiento fueron sometidos a un test de Student apareado utilizando el programa Infostat v 2010. Se encontró una diferencia significativa en la inclinación axial del incisivo inferior post tratamiento cualquiera sea la técnica utilizada, aumenta en ambos casos. No se realizó discriminación de torques (Roth ­ 1°, Damon torque estándar ­ 3°, Damon bajo torque - 11°) (AU)


This research work aims to compare the inclination of the lower incisor before and after treatment in patients treated orthodontically with Roth techniques and Damon technique to which no exodontics were performed. The study group consisted of 150 adult patients with complete permanent dentition who have been treated in Circulo Argentino de Odontología. To measure the inclination the Tweed formula was used: IMPA angle, axial axis of the lower incisor with the mandibular plane. The values taken from the pre and post-treatment plots were subjected to a Student test paired using the Infostat v 2010 program. A significant difference was found in the axial inclination of the lower incisor post treatment whatever the technique used, it increases in both cases. No torques discrimination was performed (Roth - 1 °, Damon standard torque - 3 °, Damon under torque - 11 °) (AU)

ABSTRACT

La maloclusión clase III se considera un reto en la práctica de todo ortodoncista. Una de las principales dudas al respecto reside en ¿cuándo es el mejor momento para intervenir? Exis- ten dos enfoques en el manejo ortodóntico del paciente: 1) la ortodoncia interceptiva; y 2) la ortodoncia correctiva. La or- todoncia interceptiva busca la prevención del establecimiento de la malolcusión. En este grupo, se encuentra el uso de más- cara facial con disyunción maxilar y el de aparatología fija (2x4 o 2x6). Por otro lado, la intervención correctiva hace re- ferencia al camuflaje de las características que trae consigo la maloclusión clase III ya establecida; dentro de este enfoque se encuentran las extracciones de piezas, el uso de minitornillos extraalveolares y la filosofía MEAW. Se puede concluir que el adecuado manejo de la maloclusión clase III radica en el oportuno y correcto diagnóstico, que debe realizarse a través de la minuciosa inspección de las características y hallazgos intra y extraorales de los pacientes (AU)


Class III malocclusion is considered a challenge in the practice of every orthodontist. One of the main questions is: when is the best time to intervene? There are 2 approaches to the orthodontic management of the patient: 1) interceptive orthodontics, and 2) corrective orthodontics. Interceptive or- thodontics seeks to prevent the establishment of malocclusion by means of the use of a facial mask with maxillary disjunc- tion, or the use of fixed appliances (2x4 or 2x6). Corrective intervention refers to camouflaging the characteristics of a Class III malocclusion that is already established. This ap- proach uses tooth extraction, extra-alveolar mini screws or the MEAW philosophy. To conclude, proper management of Class III malocclu- sion is based on timely, correct diagnosis, which must be made through careful inspection of the characteristics and intraoral and extraoral findings in patients (AU)

ABSTRACT

Introducción: Los minitornillos de ortodoncia son dispositivos temporales de anclaje utilizados ampliamente en ortodoncia correctiva. Sin embargo, se ha reportado en la literatura que su tasa clínica de éxito no es completa debido a que pueden existir fallas relacionadas con la pérdida de su estabilidad. Varios factores pueden comprometer el anclaje y están relacionados con el tipo de implante, su manejo quirúrgico y el hospedero. Dentro de este último, se encuentra la inflamación del tejido periimplantario o mucositis que, aunque reversible, es necesario su tratamiento temprano para evitar su progresión a la afectación de tejido duro (periimplantitis). Objetivo: Describir un caso clínico de mucositis periimplantaria asociada a un dispositivo de anclaje ortodóntico temporal. Presentación del caso: Paciente femenina que acudió a la consulta por presentar dolor en la zona anterior del maxilar superior. Durante el examen intraoral se observó que usaba aparatos de ortodoncia con mecanismo de anclaje: dos minitornillos de ortodoncia ubicados al nivel de los caninos superiores. Se realizó la remoción quirúrgica de los minitornillos de ortodoncia, se le indicó el uso de antibióticos y se realizó estudio histopatológico para descartar malignidad. Se diagnosticó con mucositis periimplantaria. Conclusiones: La remoción quirúrgica de los minitornillos de ortodoncia es una excelente alternativa para evitar la progresión de la lesión hacia los tejidos duros. A través de esta técnica lograron eliminar signos de dolor, enrojecimiento y sangrado(AU)


Introduction: Orthodontic miniscrews are temporary anchorage devices widely used in corrective orthodontics. However, it has been reported in the literature that their clinical success rate is not high, due to failures related to the loss of stability. Anchorage may be affected by factors associated to the type of implant, its surgical management and the host. Host-related factors include peri-implant tissue inflammation or mucositis, which though reversible, its early treatment is necessary to prevent expansion into and damage to the hard tissue (peri-implantitis). Objective: Describe a clinical case of peri-implant mucositis associated to a temporary orthodontic anchorage device. Case presentation: A female patient attends clinical consultation with pain in the anterior zone of her upper maxilla. Intraoral examination revealed the presence of orthodontic appliances with an anchorage mechanism: two orthodontic miniscrews located at the level of the upper canines. Surgical removal was performed of the orthodontic miniscrews, antibiotics were indicated and histopathological testing was conducted to rule out malignancy. The patient was diagnosed with peri-implant mucositis. Conclusions: Surgical removal of orthodontic miniscrews is an excellent alternative to prevent the progress of the lesion into hard tissues. Pain signs, reddening and bleeding were all eliminated with the technique applied(AU)

ABSTRACT

Objetivo: Describir el tratamiento endodóncico de cuatro casos clínicos de reabsorción radicular desarrollada durante o tras un tratamiento ortodóncico. Casos clínicos: Después de la preparación y la desinfección de los conductos radiculares, estos fueron obturados por un tiempo prudencial con una medicación intraconducto de hidróxido de calcio, que luego fue reemplazada por MTA. Luego de un período de entre uno y cuatro años, según el caso, los tratamientos fueron evaluados clínica y radiográficamente. Los dientes que debieron ser extraídos fueron analizados histológicamente. Según la evolución clínica y radiográfica de los casos presentados, el uso inicial de hidróxido de calcio y su posterior reemplazo por MTA parecería ser un protocolo adecuado para completar el proceso de reparación de los tejidos apicales y perirradiculares en casos de reabsorciones radiculares provocadas por fuerzas ortodóncicas excesivas. Las enfermedades sistémicas deben ser tenidas en cuenta para la elección de la terapéutica (AU)


Aim: To describe the endodontic treatment of four clinical cases of permanent teeth suffering root resorption during or after orthodontic treatment. Clinical cases: Four clinical cases of permanent teeth with root resorption were endodontically treated. After the root canals were prepared and disinfected, they were medicated with calcium hydroxide. After an appropriate observation period, the canals were finally filled with MTA. The treatment outcomes were clinically and radiographically assessed at an interval between one to four years according to the clinical case. The histological findings of teeth that required extraction was also described. Our clinical and radiographic observations suggest that a temporary filling with calcium hydroxide and further obturation with MTA can provide a favorable intracanal environment for apical and periradicular tissue reparation. The clinician needs a full medical history to be aware of the systemic diseases in patients with root resorption that will be of importance for the proper selection of treatment (AU)

ABSTRACT

Background: To correlate the need for orthodontic treatment between the self-perception of Chilean adolescents from 14 to 18 years old with the observation of a dentist using the same assessment scale, as well as to determine if covariates such as gender, age and type of school influence the self-perception of the adolescent and the examiner. Material and Methods: Cross-sectional descriptive study of adolescents aged 14 to 18 years from public, subsidized and private schools in Temuco, Chile. The probability sample is stratified by course, from first to fourth year, a total of 414 students participated, according to the eligibility criteria. The photographic score of the aesthetic component (AC) of the Index of Orthodontic Treatment Need (IOTN) was used. The statistical analysis of the data was performed with the SPSS Statistics program v.23. Results: 94.9% of the adolescents perceived themselves as having good aesthetics. The examiner considered that 77% presented this condition, p<0.00. Males perceived themselves better than females. At age 15, 1.7% of students considered themselves to have poor aesthetics, p<0.01. From the examiner's perspective, aesthetics are related to type of school, p<0.00. Conclusion: Adolescents perceive themselves better aesthetically than do the evaluators. The school type factor, according to the IOTN-AC examiner, shows a higher proportion of students with no need for orthodontic treatment in private schools, and a threshold need in municipal and subsidized institutions.


Correlacionar la necesidad de tratamiento ortodóncico, entre la autopercepción de adolescentes con el diagnóstico de un evaluador odontólogo, utilizando la misma escala de valoración, así también determinar si las variables como el género, la edad y la dependencia educacional influyen en la autopercepción del adolescente y la observación del examinador. Material y Métodos: Estudio descriptivo de corte transversal, en adolescentes de 14 a 18 años de escuelas públicas, subvencionadas y privadas de Temuco-Chile. Muestreo probabilístico estratificado por cursos, de primero a cuarto medio con una muestra de 414 estudiantes, según los criterios de elegibilidad. Se utilizó el score fotográfico del componente estético (AC) del Índice de Necesidad de Tratamiento de Ortodoncia (INTO). El análisis estadístico de los datos fue realizado con el programa SPSS Statistics v.23. Resultados: El 94,9% de los adolescentes se autoperciben con una buena estética, el examinador considera que un 77% presenta esta condición, p<0,00. Los varones se perciben mejor que las damas. Los adolescentes de 15 años un 1,7% considera tener mala estética, p<0,01. Desde la perspectiva del examinador la estética se relaciona con la dependencia educacional, <0,01. Conclusión: Los adolescentes se autoperciben mejor estéticamente que lo diagnosticado por evaluadores odontólogos. El factor dependencia educacional según INTO-AC examinador, muestra mayor proporción de estudiantes sin necesidad de tratamiento ortodóncico en los establecimientos privados, y necesidad límite en los públicos y subvencionados.

ABSTRACT

ABSTRACT Objective To evaluate the accuracy of three different digital bracket positioning systems, comparing vertical, mesiodistal and buccolingual accuracy. Material and Methods The same case was sent to Orapix, Insignia, and Orthocad systems and the brackets were bonded to the malocclusion models.Damon 3 MX brackets were used with all systems and the brackets were bonded to the models with the same bonding protocol and materials. The comparison of the position of each single bracket was made with digital photography, and ImageJ software was used to find the length in pixels and then convert it to hundredths of a mm for vertical, mesiodistal and buccolingual displacement, compared to the setup. Results Insignia System reported the average higher vertical displacement (0.28 mm), compared with the other two appliances (0.22-0.23 mm), and showed the lowest average displacement for the mesiodistal and buccolingual positioning (0.14 and 0.07 mm, respectively).However, these slight bracket positioning variations between these bonding systems were not statistically different (p>0.05). Conclusion The three systems analyzed were shown to be accurate in positioning the brackets, and none of them was statistically better.

ABSTRACT

Abstract Objective: To analyze differences in vertical mandibular and trunk symmetry in orthodontic patients. Material and Methods: This was a cross-sectional study of 129 growing orthodontic patients who sought orthodontic treatment at the Dental Hospital Universitas Sumatera Utara, Indonesia. Mandibular symmetry index was observed with pre-treatment panoramic radiography based on Kjellberg's technique and trunk symmetry was evaluated based on questionnaires and visual observation. Vertical mandibular asymmetry was decided if the index of asymmetry was lower than 93.7%. The bivariate analysis used the chi-squared and Fisher's exact tests, with a significance level of 5%. Results: There was a significant association between vertical mandibular and trunk symmetry (p<0.05). The prevalence odds ratio for the association with vertical mandibular asymmetry was 3.007 (95% CI = 1.016-8.905) for trunk asymmetry. Conclusion: The necessity to consider trunk symmetry could be included in orthodontics treatment of any malocclusion with vertical mandibular asymmetry that might require a multidisciplinary approach in the future.

ABSTRACT

ABSTRACT Objctive: To assess the soft tissue characteristics of Bangladeshi adults to formulate soft tissue 3D CT standards using Holdaway's (HA) and lip morphology (LM) analyses. Another aim of this study was to assess the gender dimorphism of Bangladeshi population. Material and Methods: One hundred and seventeen (Eighty-five men and Thirty-two women) Bangladeshi adults have obtained their computed tomography (CT) scan at the Radiology Department for normal diagnosis. Craniofacial deformities were undetected in all cases. The CT images were prepared by a 3D imaging programming software (Mimics 11.02 Materialise). Parameters from the identified landmark points were measured in 3D through this software. Results: Upper lip thickness (ULT) (vermillion UL-A point) measurement was significant in HA and in LM analyses, upper lip protrusion (ULP) (Ls to Sn-SPog) measurement has demonstrated significant difference among both genders, where p-value was less than 0.05. Mean measurements of Bangladeshi adults were relatively comparable except the face convexity (FC) when compared with the HA cephalometric soft tissue values. Conclusion: By using HA and LM analyses, 3D CT soft tissue standards were established for Bangladeshi adults. Measurements for all parameters have remained equivalent with the HA standard data apart from the FC measurement. This consequently may demonstrate that the Bangladeshi population retains a convex shape with a slight protrusive lip or retruded chin.

ABSTRACT

Case report: This article presents the case of an 11-year-old patient who sought orthodontic treatment, complaining of crooked teeth. In anamnesis, an emotional and physical dependence was reported regarding the act of breastfeeding. Considerations on the diagnosis, psychological implications, and clinical approach in this rare case were addressed. An orthodontic treatment and myofunctional therapy were performed to resolve the occlusal and functional aspects of the patient. Psychological therapy for the child and her mother was required to handle emotional sequelae. Conclusion: Multidisciplinary treatment was prescribed. Dentists should be aware of this need in cases of patients with special characteristics for treatment beyond oral problems. In orthodontics, this may be the difference between effective treatment outcomes or not.


Relato de caso: Este artigo apresenta o caso de uma paciente de 11 anos que procurou tratamento ortodôntico com queixa de "dentes tortos". Na anamnese, foi relatada dependência emocional e física da criança em relação ao ato de amamentar. Considerações sobre diagnóstico, implicações psicológicas, abordagem clínica neste raro caso foram abordadas. Foi realizado tratamento ortodôntico e terapia miofuncional para resolução dos aspectos oclusais e funcionais do paciente. Um acompanhamento psicológico para crianças e sua mãe foi necessária para abordar sequelas emocionais inerentes. Conclusão: Um tratamento multiprofissional foi instituído e o dentista deve estar atento a essa necessidade nos casos de pacientes com características especiais, visando uma abordagem além dos problemas bucais. Na Ortodontia, essa pode ser a diferença entre os resultados eficazes do tratamento ou não.

ABSTRACT

ABSTRACT Objective: To evaluate the prevalence and severity of malocclusion in children suffering from β-thalassemia and to assess orthodontic treatment need using Grainger's Treatment Priority Index (TPI) and index of orthodontic treatment need (IOTN)-dental health component (DHC). Methods: A cross-sectional study was conducted on 200 transfusion-dependent children diagnosed with homozygous β-thalassemia and 200 healthy school children aged 11-17 years. The TPI and IOTN-DHC data was recorded for both groups. Total TPI score for each subject was calculated and graded according to malocclusion severity estimate (MSE). Independent sample t-test was used to compare mean TPI scores, overjet and overbite between thalassemic and healthy children. Chi-square test was used to compare the frequency of IOTN-DHC grades, Angle's classification, and MSE grades between thalassemic and healthy children. Results: The most prevalent malocclusion was Class I in normal children (67.5%) and Class II in thalassemic children (59%). The mean overjet and overbite were significantly (p<0.001) greater in thalassemic children than in healthy children. Severe tooth displacements were 3.5 times greater in thalassemic children, compared to controls. A greater proportion of thalassemic children were in IOTN grades 3 and 4, compared to the controls (p<0.001). MSE grades 4 and 5 were significantly (p<0.001) more prevalent in thalassemic children, compared to the controls. Conclusion: There is a high prevalence of Angle's Class II malocclusion in thalassemic children. Majority of these children are categorized in higher grades of IOTN-DHC and TPI-MSE, showing a great severity of malocclusion and high orthodontic treatment needs.


RESUMO Objetivo: Avaliar a prevalência e gravidade da má oclusão em crianças que sofrem de beta-talassemia e mensurar a necessidade de tratamento ortodôntico usando o Índice de Prioridade de Tratamento (IPT) de Grainger e o Índice de Necessidade de Tratamento Ortodôntico (Index of Orthodontic Treatment Need - IOTN) - Componente de Saúde Dental (Dental Health Component - DHC). Métodos: Um estudo transversal foi conduzido com 200 crianças com diagnóstico de beta-talassemia homozigótica dependentes de transfusão e 200 crianças saudáveis em idade escolar, entre 11 e 17 anos. Os dados do IPT e do IOTN-DHC foram documentados para ambos os grupos. A pontuação total do IPT para cada sujeito foi calculada e classificada de acordo com a Estimativa de Severidade da Má oclusão (ESM). O teste t para amostras independentes foi usado para comparar os escores médios de IPT, sobressaliência e sobremordida, entre as crianças saudáveis e as com talassemia. O teste qui-quadrado foi usado para comparar a frequência dos escores do IOTN-DHC, a classificação de Angle e os escores do ESM entre crianças com beta-talassemia e crianças saudáveis. Resultados: A má oclusão mais prevalente foi a Classe I em crianças normais (67,5%) e a Classe II em crianças com beta-talassemia (59%). Os valores médios de sobressaliência e a sobremordida foram significativamente (p< 0,001) maiores em crianças com beta-talassemia do que em crianças saudáveis. Os deslocamentos dentários graves foram 3,5 vezes maiores em crianças com beta-talassemia em comparação com os controles. Uma proporção maior de crianças com beta-talassemia estava nos escores 3 e 4 do IOTN em comparação com os controles (p <0,001). Os escores 4 e 5 de ESM foram significativamente (p< 0,001) mais prevalentes em crianças com beta-talassemia em comparação com os controles. Conclusão: Há uma alta prevalência de má oclusão de Classe II de Angle em crianças com beta-talassemia. A maioria dessas crianças é categorizada em escores superiores de IOTN-DHC e IPT-ESM, mostrando uma grande gravidade de má oclusão e alta necessidade de tratamento ortodôntico.

ABSTRACT

La evolución de la ortodoncia, desde sus inicios, ha demostrado hechos destacables como el surgimiento de la técnica de arco recto, el desarrollo de prescripciones variadas, el uso de ranuras con diferentes dimensiones, sistemas de anclaje esquelético, tomografía... A pesar de ello, los diseños y las características que presentaban los brackets eran siempre los mismos y limitados. La historia de las grandes ideas es vasta, pero debían estar unidas en una sola pieza. Esto es lo que hicieron los autores de este artículo, al desarrollar un nuevo diseño de bracket que cuenta con dos slots centrales y cada una con diferentes dimensiones, un slot tiene dimensiones de 0.018 "X 0.030" y el otro 0.022 "X 0.028", abriéndse una gama de posibilidades. A partir de ahora contamos con una herramienta de trabajo con varios recursos, que genera grandes beneficios para profesionales y pacientes, y que gana cada día más seguidores (AU)


The evolution of orthodontics, since its beginnings, has demonstrated remarkable events such as the appearance of the straight wire technique, the development of varied prescriptions, the use of slots with different dimensions, skeletal anchoring systems, tomography ... Despite this, the designs and the features that the brackets presented were always the same and limited. The history of great ideas is vast, but they needed to be united in one piece. This is what the authors of this article did, when developing a new bracket design that features two central slots and each with different dimensions, one slot has dimensions of 0.018 "X 0.030" and the other 0.022 "X 0.028" with a fan of possibilities is being opened. Now, a work tool with several resources, which generates great benefits for professionals and patients is gaining more followers every day (AU)

ABSTRACT

Objetive: The objective of this clinical trial was to investigate the perception of pain during initial maxillary alignment with an adjunctive procedure of micro-osteoperforations (MOPs) compared to conventional orthodontics. Material and methods: This study design was a single-centre, two-arm parallel prospective randomised clinical trial. Thirty consecutive adult subjects (25 females and 5 males; mean age ± SD, 22.66 ± 3.27 years) with 5-8mm moderate upper labial segment crowding were randomly allocated using block randomisation into intervention and control group. All subjects had first premolar extractions, bonded conventional fixed appliances and 0.014-inch nickel-titanium archwire was placed for initial alignment. The intervention group received a 3-mm deep MOPs procedure under local anaesthesia using a Propel device (PROPEL Ortho Singapore) on the labiogingival aspect between the maxillary incisors. Both groups received a set of 100 mm visual analogue scale to complete over the first week, recording pain at 24 hours, 3 days and 1 week. Data were analysed using repeated-measures analysis of variance (ANOVA). Results: There was a statistically significant difference observed in perceived pain levels between MOPs and the control group on day 1, day 3 and day 7 postoperatively. Pain perception was significantly lower in the intervention group at all time points. Conclusion: Accelerating orthodontic tooth movement with MOPs did not accentuate pain perceived during initial maxillary alignment with fixed appliances.


Objetivo: El objetivo de este ensayo clínico fue investigar la percepción del dolor durante la alineación maxilar inicial con un procedimiento adyuvante de micro-osteoperforaciones (MOP) en comparación con la ortodoncia convencional. Material y Métodos: El diseño de este estudio fue un ensayo clínico aleatorizado prospectivo paralelo de dos brazos y un solo centro. Treinta sujetos adultos consecutivos (25 mujeres y 5 hombres; edad media ± DE, 22,66 ± 3,27 años) con apiñamiento moderado del segmento labial superior de 5-8 mm se asignaron al azar mediante la asignación al azar en bloques en el grupo de intervención y de control. A todos los sujetos se les realizaron extracciones de los primeros premolares, se colocaron aparatos fijos convencionales adheridos y se colocó un arco de níquel-titanio de 0,014 pulgadas para la alineación inicial. El grupo de intervención recibió un procedimiento de MOP de 3 mm de profundidad bajo anestesia local utilizando un dispositivo Propel (PROPEL Ortho Singapore) en la cara labial de los incisivos superiores. Ambos grupos recibieron un conjunto de escala analógica visual de 100 mm para completar durante la primera semana, registrando el dolor a las 24 horas, 3 días y 1 semana. Los datos se analizaron mediante análisis de varianza de medidas repetidas (ANOVA). Resultados: Se observó una diferencia estadísticamente significativa en los niveles de dolor percibido entre los MOP y el grupo de control el día 1, el día 3 y el día 7 del postoperatorio. La percepción del dolor fue significativamente menor en el grupo de intervención en todos los momentos. Conclusión: La aceleración del movimiento dental de ortodoncia con MOP no acentuó el dolor percibido durante la alineación maxilar inicial con aparatos fijos.

ABSTRACT

A continuación se presenta un caso de un paciente de 12 años de edad, con antecedente de bruxismo, con biotipo mesofacial, tercio inferior dolicofacial, hipertonicidad muscular en maseteros, cierre labial forzado con incompetencia labial de 4 milímetros con dolor en sinoviales anteriores inferiores. Los objetivos de tratamiento consistieron en lograr relajación muscular y promover un posicionamiento condilar ortopédicamente funcional y estable, realizar control vertical para disminuir gap interlabial, alinear líneas medias, mantener clase I molar bilateral, clase I canina bilateral y clase I incisiva, crear overjet y overbite adecuados, con recuperación estética y función del segmento anterior. Debido a eventos adversos durante la etapa de cierre de espacios, la clase molar y canina I no se logró, pero se aseguró mediante ameloplastias positivas la función y estética adecuadas para tener un tratamiento de ortodoncia estable a largo plazo (AU)


The following is a case of a 12-year-old patient, with a history of bruxism, with a mesofacial biotype, lower third of the facial area, muscular hypertonicity in the masseters, a forced labial closure with a 4-millimeter labial incompetence with pain in inferior anterior synoviums. Treatment objectives consisted of achieving muscle relaxation and promoting orthopedically functional and stable condylar positioning, perform vertical control to decrease interlabial gap, align midlines, maintain bilateral molar class I, bilateral canine class I and incisive class I, create adequate overjet and overbite, with aesthetic recovery and function of the anterior segment. Due to adverse events during the closing phase of spaces, the molar and canine I class was not achieved, but positive function and aesthetics were ensured by positive ameloplasties in order to have a long-term stable orthodontic treatment (AU)

ABSTRACT

Abstract This retrospective study evaluated facial profile pleasantness determined by two protocols of Class II treatment. The sample comprised facial profile silhouettes obtained retrospectively from the pretreatment (T1) and posttreatment (T2) cephalograms of 60 patients (42 males and 18 females) divided into two groups. One group of 30 patients (mean age of 12.84 years) was treated with the extraction of maxillary first premolars (mean treatment time of 2.7 years), and the other group of 30 patients (mean age of 12.81 years) was treated with a mandibular advancement appliance (Forsus) (mean treatment time of 2.49 years). The facial profile silhouettes (T1 and T2) were randomly distributed in an album containing one patient per sheet. The examiners consisted of 60 orthodontists and 60 lay individuals, who analyzed the profiles in regard to facial pleasantness, using the Likert scale. A comparison between stages T1 and T2 of the two treatment protocols and between the examiners was performed by mixed-design analysis of variance at a significance level of 5%. The results demonstrated a significant difference between T1 and T2 (greater scores for T2 compared to T1), and between lay individuals and orthodontists (orthodontists assigned higher scores), but with no significant difference between the treatment protocols. Both protocols produced positive effects on the facial profile esthetics, from the standpoint of lay individuals and orthodontists.

ABSTRACT

Abstract Objective: To approbate the complex approach for assessment of second molar mesialization outcomes with the use of orthodontic mini-implants. Material and Methods: The sample consisted of 62 patients, divided into study (n=32) and control group (n=30). Mesialization procedure in the study group was conducted with the use of braces system and orthodontic mini-implants as additional anchorage devices, while in control group mesialization was provided only with the use of the brace system. Dynamic registration of bone level changes and the entire range of tooth movement were carried out on digital orthopantomograms obtained with the use of Planmeca ProMax 2D. Results: Findings of orthopantomographic (OPG) analysis have shown that cases of second molar mesialization with the use of mini-implants as temporary anchorage characterized with more stable conditions of bone levels around displaced teeth compare to cases, where mesialization was provided only with the use of braces systems without any additional anchorage. The terms of treatment in the study group with the use of dental mini-implants as the anchorage was reduced by 8.8 ± 0.12 months compared to the control group (p<0.05). Conclusion: The use of orthodontic mini-implants as anchorage constructions during the mesialization of the mandibular second molars contributes to the reduction of treatment duration and support the more prognostic movement of teeth, that does not provoke significant pathological changes in the levels of the surrounded alveolar ridge and minimize the risk of associated periodontal complication occurrence.

ABSTRACT

RESUMEN La transposición dentaria se define como una ectopia del germen dentario, es común encontrarla en caninos superiores, pero cuando esta entidad se combina con una transposición se convierte en un dilema para el ortodoncista. Su etiología es multifactorial y no está bien aclarada, es conocido que se produce en el momento de la formación embrionaria por un intercambio en la posición del germen dentario, y con frecuencia, se considera ligado a factores genéticos. Se relaciona con trauma en el área afectada y con interferencias mecánicas. Se presentó un paciente de 14 años de edad, sexo masculino, que solicitó tratamiento por tener los dientes "botados" y un diente "fuera de lugar". Al examen clínico se observó transposición de 23 con 2:4. Se colocó aparatología fija con técnicas de cementado directo y bandas en los primeros molares permanentes superiores, se determinó mesializar el 23 y dejar libre 24, para evitar daño radicular. Una vez colocado 23 en su posición, 24 fue distalado y alineado al arco; para esto se utilizó arcos térmicos de nitinol preformados y secciones con elastómeros. Se logró neutroclusión de molares y caninos sin perjudicar los tejidos de soporte (AU).


ABSTRACT Tooth transposition is defined as an ectopia of the tooth germ, commonly found in upper canines, but when this entity is combined with a transposition, it becomes a dilemma for the orthodontists. Its etiology is multi-factorial and unknown. It takes place at the moment of the embryonic formation due to an interchange in the position of a tooth germ, and it is frequently considered linked to genetic factors. It is related to trauma in the affected area and with mechanic interferences. We present the case of a male patient, aged 14 years, who asked treatment for having buckteeth and a tooth ¨out of place¨. At the clinical examination it was observed the transposition of the 23 with 24. A fixed brace was put with direct cement techniques and bands in the first permanent upper molars. The orthodontist decided to mesialize 23 and let 24 free, to avoid root damage. Once 23 was in its position, 24 was distalized and aligned to the arch using pre-formed thermic nitinol arches and sections with elastomers. The molars and canines neutral occlusion was achieved without damaging the support tissues (AU).

ABSTRACT

¿Qué es la estética? Es más que un concepto frívolo. Tiene que ver con la armonía facial, la autoestima, la autoimagen, la percepción de belleza. Es un concepto que involucra al individuo en su totalidad, en su ser, que va más allá de frivolidad estética. Muchos pacientes que vienen a la consulta no expresan inicialmente su real demanda. Expresan problemas funcionales, pero su real preocupación, en la mayor parte de los casos, es estética. Pueden manifestar que no pueden comer bien, masticar un alimento o que no respiran bien o sesean, pero su motivación principal es estética y tiene que ver con su propia autoestima. Las funciones de respiración, deglución, fonación, masticación, oclusión deben estar entre los objetivos a conservarse o restituirse por parte del especialista, pero el tratamiento sería un fracaso si no atendemos la demanda, a veces no bien explicitada, por el paciente y que responde a su profunda necesidad real. Para la OMS, la salud puede definirse como el estado completo de bienestar físico, mental y social. Nuestro objetivo, como agentes de salud, será poder satisfacer la demanda explícita o encubierta con la mayor estética y la mayor funcionalidad (AU)


What is aesthetics? It is more than a frivolous concept. It has to do with facial harmony, self-esteem, self-image, the perception of beauty. It is a concept, which involves the individual as a whole, in his being, which goes beyond aesthetic frivolity. Many patients who come to the office do not initially express their real demand. They express functional problems, but their real concern, in most cases, is aesthetic. They may state that they cannot eat well, chew a food or that they do not breathe well or sedate, but their main motivation is aesthetic and has to do with their own self-esteem. The functions of breathing, swallowing, phonation, chewing, occlusion should be among the objectives to be retained or restored by the specialist, but the treatment would be a failure if we do not meet the demand sometimes not well explained by the patient and responding to their Deep real need. For WHO, health can be defined as the complete state of physical, mental and social well-being. Our goal, as health agents, will be to be able to meet the explicit or covert demand with the greatest aesthetics and functionality (AU)
