ABSTRACT

Aim: To derive and validate a short version of the Oral Health Impact Profile (OHIP) in Spanish to measure oral health quality of life (OHRQoL) for subjects wearing fixed orthodontic appliances. Methods: Cross-sectional study (data for sensitivity to change analysis were collected longitudinally). The data of 400 subjects (27.34 years, SD 11.66 years, 231 women, and 169 men) were used to develop a short-form instrument, and the data of 126 other subjects (25.95 years, SD 12.39 years, 62 women, and 64 men) were used for its validation. The original OHIPs were translated into Spanish using an iterative forward-backward sequence. After face and content validity were evaluated by an expert committee, an exploratory factorial analysis (EFA) was used to derive the Spanish short-form instrument (OHIP-S14 Ortho). To validate the OHIP-S14 Ortho, validity (content validity assessed by EFA, construct validity assessed by confirmatory factor analysis (CFA), discriminative validity assessed by the Kruskal-Wallis test, and reliability (internal consistency assessed by Cronbach's α test-retest, and inter-observer reliability assessed by correlation coefficients) were evaluated. Sensitivity to change and usefulness of the scale were also evaluated. Results: The OHIP-S14 Ortho included only six of the items in Slade´s original OHIP-14 short-form. A two-factor structure with adequate discriminative validity was found. High internal consistency (α=0.912), excellent inter-observer (Lin's correlation=0.97±0.011; rho= 0.97), test-retest agreement (Lin's correlation=0.80±0.059) and adequate sensitivity to change were also found. Conclusions: The OHIP-S14 Ortho is a valid and reliable instrument to measure OHRQoL in Spanish-speaking patients with fixed orthodontic appliances

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

Abstract The purpose of this in vitro study was to evaluate the force decrease of different elastomeric chains after different times: initial, 10 minutes, 1 day, 28 days and after mechanical brushing. Twenty orthodontic elastomeric chains segments were utilized for each commercial brand. Initially, the elastomeric chain of 15mm long were immediate stretched up to 20 mm in an Instron and the force was measured in gf. After all specimens were placed stretched on rectangular acrylic jigs with distance of 20 mm, immersed in deionized water at 37oC for 10 minutes and the force (gf) was measured again. Five test measurements of remaining force were made at the following time intervals: initial, 10 minutes, 1 day, 28 days and mechanical brushing. After 28 days, the acrylic plates with the specimens were adapted in the mechanical brushing machines (MSCT 3) and the elastomeric chains were submitted to mechanical brushing and the force (gf) measure again. The force (gf) was submitted to mixed-model ANOVA and Sidak post-hoc test (α=0.05). A statistically significant reduction in the force was found for all orthodontic elastomeric chain types after 1 day, 28 days and mechanical brushing (p<0.05). Morelli and 3M Unitek elastomeric chains showed significantly higher force than Abzil and GAC (p<0.05) after 1 day, 28 days and mechanical brushing. In conclusion, the force delivered by all elastomeric chains decayed rapidly over time. Morelli and 3M Unitek elastomeric chains consistently had a significantly greater force after mechanic brushing, while GAC the lowest.

ABSTRACT

Introducción: La falta de un incisivo permanente no solo genera un efecto adverso en la estética facial, también altera la función, en especial, la guía incisiva. Los incisivos superiores pueden sufrir bloqueo mecánico o cambio en su erupción por un diente supernumerario, un golpe u otro factor. El tratamiento de elección es el quirúrgico-ortodóncico. El pronóstico dependerá de la edad, situación, posición del diente, morfología, tamaño, maduración radicular y método de tracción. Conocer el uso de una aparatología ortodóncica que sea fácil de manipular y pueda ser usada desde edades tempranas servirá de valioso aporte. Objetivo: Mostrar el uso exitoso de un cantiléver para traccionar ortodóncicamente un incisivo impactado en posición horizontal. Presentación del caso: Paciente de 8 años con maloclusión clase I, pieza 2.1 retenida en posición horizontal, presencia de supernumerario y persistencia de pieza 6.1. Se opta por extracción de supernumerario, liberación de pieza 2.1 y tracción ortodóncica. Se usó un cantiléver por vestibular confeccionado en arco de acero redondo 0.020" con dos círculos en cada extremo para brindar elasticidad y anclaje. La fuerza utilizada fue de 70 g, pasado 6 meses se alcanzó el plano de oclusión. Se cementaron brackets y tubos, se continuó con la secuencia de arcos, hasta llegar al arco acero 0.021"x0.025" durante 11 meses. Se obtiene una posición final óptima que favorece la formación radicular y cierre apical. Conclusiones: El uso del cantiléver para el tratamiento ortodóncico de incisivos permanentes impactados en posición horizontal demostró ser exitoso, fácil de manipular y controlar(AU)


Introduction: The lack of a permanent incisor not only generates an adverse effect on facial aesthetics but also alters its function, especially the incisor guidance. Upper incisors can suffer mechanical blockage or change in their eruption due to a supernumerary tooth, a blow or another factor. The treatment of choice is orthodontic-surgical. The prognosis depends on the age, tooth position, morphology, size, root maturation and traction method. Knowing the use of an orthodontic appliance, which is easy to handle and can be used from an early age, will be of valuable contribution. Objective: To show the successful use of a cantilever to enable orthodontic traction of an impacted incisor in a horizontal position. Case presentation: Eight-year-old patient with class I malocclusion, specimen 2.1 retained in a horizontal position, presence of supernumerary tooth and persistence of specimen 6.1. Extraction of the supernumerary, release of specimen 2.1 and orthodontic traction is chosen. A buccal cantilever made of a 0.020" round steel arch with two circles at each end was used to provide elasticity and anchoring. The force used was 70 g. Six months after, the occlusion plane was reached. Brackets and tubes were cemented and the sequence of arches was continued until the 0.021"x0.025" steel arch was reached in 11 months. An optimal final position is obtained, favoring root formation and apical closure. Conclusions: The use of the cantilever for orthodontic treatment of impacted permanent incisors in a horizontal position proved to be successful as well as easy to manipulate and control(AU)

ABSTRACT

ABSTRACT Objective: To analyze and compare the stiffness of different lingual appliances with different archwires. Material and Methods: The three-point bending test was used to analyze the stiffness of the lingual archwires for the different lingual systems: eBrace, Harmony, Incognito, and STb. The deflection load curve of each archwire was obtained to evaluate how the section, the material and the manufacturer affect the elasticity and stiffness characteristics of the wires. The comparison of the stiffness between different systems was carried out through a factor variance analysis with three factors (manufacturer, cross-section, and material), followed by the post-hoc Tuckey test. Results: An increase in the system's rigidity was reported as the wire section increases, regardless of the manufacturer. The stainless steel archwires have ever higher stiffness values than NiTi and TMA. The STb wires of CuNiTi material, by virtue of the characteristics of the thermal wires, have flatter and lower load-deflection curves than the NiTi wires of other manufacturers. Conclusion: Archwires section and material showed a significant influence on the stiffness of the lingual systems. Archwires of the same section and material but different manufacturers show different load-deflection curves of stiffness.

ABSTRACT

ABSTRACT Objective: To obtain reference values for tip, torque and in-out from digital models of Italian and Mozambican subjects in ideal occlusion using a repeatable and validated method and to compare these measurements with previously reported values. Material and Methods: Dental parameters were acquired from digital models of each subject, categorized to one of two groups: Italians (23 males, 27 females; mean age 28.3 years, ±5.7 years) and Mozambicans (14 males, 15 females; mean age, 23.4 years, ±5.9), using VAM software. All subjects had ideal occlusion, permanent dentition and no previous orthodontic treatment, fillings or prostheses. After normality of data was assumed (p<0.05), a paired t-test was performed to detect any statistical differences between the two groups (p<0.05). Then, classical inference (t-test and power analysis) was used to compare our data to those reported by other authors. Results: Mozambicans' incisors were more proclined, while their upper molars appeared to be more prominent regarding Italians'. Italians shown greater tip values, especially at the upper first premolars and lower first molars. In-out values were comparable between the two groups, except for the upper molars (more prominent in Mozambicans) and lower first molar (more prominent in Italians). Unlike other reports, upper second molars displayed negative tip in our samples. Conclusion: Pre-adjusted appliances with standard prescription should not be expected to guarantee optimal outcomes. Prescriptions specific for ethnicities are recommended and reference values should be reconsidered.

ABSTRACT

Abstract Objective: To determine differences in how orthodontic patients perceive the aesthetics relating to the use of Essix and Hawley retainers. Material and Methods: Photographs of a female patient using an Essix retainer and a Hawley retainer, respectively, were assessed by 70 orthodontic patients aged between 21 and 55 years. All participants were provided with the same images of the two retainer types being worn and were asked to grade the aesthetics of each retainer using a visual analog scale. The significance of differences in orthodontic patient perceptions of aesthetics in the use of Essix and Hawley Retainers in the young adult and adult age groups were tested using the Mann-Whitney test with assumed significance p<0.01. Results: There were differences in participants' perceptions between the two retainers that were statistically significant, with responses varying between young adults aged 21 to 35 years and adults aged 36 to 55 years. According to the VAS, the two retainers' average scores in the total population are 82 for Essix Retainer and 60 for Hawley Retainer in both groups. Conclusion: The Essix retainer as a retention appliance is considered more aesthetically pleasing than the Hawley retainer among both young and middle-aged adults.

ABSTRACT

ABSTRACT Objective: To evaluate the effects of passive self-ligating appliances (PSLAs) and conventional ligating appliances (CLAs) during orthodontic treatment regarding torque, tip, and transversal dental changes. Material and Methods: Dental parameters were digitally acquired from pre- and post-treatment models of each subject belonging to two groups of patients treated with PSLAs (23 patients; 11 females and 12 males with a mean age of 14.2 ± 1.6 years) and CLAs (18 patients; 10 females and 8 males with a mean age of 14.3 ± 1.9 years), respectively. All subjects had Class I or slight Class II malocclusion (= 2mm), permanent dentition and no previous orthodontic treatment. After normality of data was assumed, a paired sample t-test rejected any side differences at T0 and, therefore, the data were grouped by tooth group. Statistical analyses were performed using a linear mixed-effect framework, assuming the appliance, time, and interactions as fixed effects and the tooth type as random effects. Finally, post-hoc effect analysis was used to contrast modeled marginal effects (p<0.05). Results: For both appliances, there is a general increase of both torque and transverse values at T1, especially for PSLAs. Tip shows a general reduction in the lateral sectors for both appliances is registered. The only significant statistical difference referred to appliances' efficacy is located to mandibular intermolar width. Conclusion: Both appliances have an expansive potential for both torque and transverse dental changes. No evident differences are detectable between appliances except for the rate of the mandibular intermolar width increase.

ABSTRACT

ABSTRACT Objective: To investigate the types of dental emergencies that occurred during the lockdown period in Italy (12th March-4th May) and to investigate future therapeutic preferences related to the use of different types of appliances. Material and Methods: A questionnaire dedicated to assessing dental emergencies during the lockdown period and surveying the resumption of orthodontic practice was submitted to clinicians in digital form. The first part of the questionnaire, focused on the orthodontic emergencies that were encountered in relation to the different types of orthodontic appliances and how these were resolved. The second part of the questionnaire was devoted to the resumption of clinical practice; in particular, it was designed to assess whether and what percentage of clinicians are willing to change the duration of appointments in relation to the different types of appliance used, asking them whether their approach to orthodontic treatment would change in the coming months as compared to the pre-COVID-19 era. Results: Results show that in most cases (82%), the percentage of patients who experienced a dental emergency was less than 5% and that far fewer emergencies were attributable to removable (5.7%) than to fixed appliances (94.3%). Looking ahead, clinicians expressed a greater preference for using removable (60.8%) rather than fixed appliances (39.2%). Conclusion: During the lockdown, there relatively few orthodontic emergencies, many of which were handled by telephone consultation. However, a far lower percentage of emergencies were generated by removable (e.g., clear aligners) as opposed to fixed appliances (e.g., multibracket equipment), likely influencing the decision of the majority of clinicians to opt for removable appliances in the wake of the COVID-19 pandemic.

ABSTRACT

ABSTRACT Objective: The aim of this study was to compare three teaching methods' time and personnel requirements, and their effects on plaque and gingival indices. Methods: This study was a single-blind randomized controlled trial on fixed orthodontic appliance candidates (n = 90), assigned into a control group (n = 30) and two different study groups (n = 30 each). The control group received standard printed educational material and was assisted with verbal information. The study groups either received video-assisted or hands-on training about fixed orthodontic appliance and oral hygiene. The time requirements for all three educational interventions was recorded during the initial visit. The adequacy of oral hygiene was documented through plaque and gingival indices during the initial visit and eighth week of the treatment. The continuous variables were analyzed using 1-way ANOVA. Tukey HSD and Student t-tests were used for post-hoc comparisons (α?#8197;= 0.05). Also, a chi-square test was used for the analysis of categorical variables. Results: Standard education failed to maintain the plaque and gingival indices at the eighth week of the treatment. Although both video-assisted and hands-on training took a considerable amount of time, they served well in preserving both of the indices at the eighth week. The longer the educational intervention was, the better the preservation of the plaque and gingival indices. Conclusion: Educational intervention, either with video-assisted or hands-on programs, provided better results in oral hygiene depending on the time and personnel constraints of the orthodontist.


RESUMO Objetivo: O objetivo do presente estudo foi comparar a duração e os pré-requisitos de equipe de três métodos de orientação ao paciente, e seus efeitos sobre os índices de placa e de sangramento gengival. Métodos: Esse foi um estudo controlado aleatório cego em candidatos (n=90) a tratamento ortodôntico fixo, que foram divididos em um grupo controle (n=30) e dois grupos de estudo (n= 30 cada). O grupo controle recebeu material educacional impresso e foi orientado com informações verbais. Os grupos de estudo receberam treinamento em formato de vídeo ou treinamento hands-on sobre o tratamento com Ortodontia fixa e higiene bucal. O tempo necessário para cada um dos três tipos de treinamento foi registrado durante a visita inicial. A qualidade da higiene bucal foi avaliada por meio dos índices de placa e de sangramento gengival durante a visita inicial e na oitava semana de tratamento. As variáveis contínuas foram analisadas utilizando-se one-way ANOVA. Os testes HSD de Tukey e t de Student foram utilizados para comparações post-hoc (α?#8197;= 0,05), e o teste qui-quadrado foi utilizado para análise das variáveis categóricas. Resultados: O método de ensino convencional fracassou em manter os índices de placa e de sangramento gengival até a oitava semana de tratamento. Apesar de tanto o método de treinamento com vídeos e de treinamento hands-on demandarem um tempo considerável, eles conseguiram manter ambos os índices até a oitava semana. Quanto mais longa a orientação realizada, melhor foi a manutenção dos índices de placa e de sangramento gengival. Conclusão: Tanto o método de treinamento com vídeo quanto no formato hands-on obtiveram melhores resultados de higiene bucal, mas dependem do tempo e das limitações de equipe de cada ortodontista.

ABSTRACT

Introducción: El dolor inducido por los aparatos de ortodoncia es una de las principales razones que desalientan a los pacientes a buscar tratamiento ortodóntico y puede afectar negativamente su cooperación. Objetivo: Determinar la relación de la percepción del dolor, rasgos de personalidad y la actitud del paciente hacia el tratamiento ortodóntico. Métodos: Estudio transversal y observacional. La muestra estuvo conformada por dos grupos: I) 200 sujetos no tratados (78 varones y 122 mujeres; edad promedio 20,02 ± 2,67 años) y II) 200 sujetos tratados (64 varones y 136 mujeres; edad promedio 20,29 ± 3,88 años). El instrumento para la recolección de datos fue un cuestionario que incluía la evaluación de la expectativa del dolor para sujetos no tratados, experiencia de dolor para sujetos tratados, los perfiles de personalidad de los pacientes y actitudes hacia el tratamiento de ortodoncia. Resultados: No se encontró relación entre la percepción del dolor, los rasgos de personalidad y actitud del paciente hacia el tratamiento ortodóntico (p > 0,05). El estado de tratamiento (presentar ortodoncia) afectó la percepción del dolor hacia el tratamiento ortodóntico (p < 0,05), el género no afectó la percepción del dolor. El estado de tratamiento y el género masculino afectaron la actitud del paciente hacia el tratamiento ortodóntico (p < 0,05). Conclusiones: Los pacientes con mejor actitud mostraron menos dolor y los pacientes con mayor percepción del dolor mostraron una actitud negativa. Los niveles bajos de amabilidad tienen efecto sobre la percepción del dolor del paciente hacia el tratamiento ortodóntico(AU)


Introduction: The pain induced by orthodontic appliances is one of the main reasonswhy patients are reluctant to seek orthodontic treatment, and may negatively affect their cooperation. Objective: Determine the relationship between pain perception, personality traits and patient attitude toward orthodontic treatment. Methods: A cross-sectional observational study was conducted of a study sample composed of two groups: I) 200 untreated subjects (78 male and 122 female; mean age 20.02 ± 2.67 years) and II) 200 treated subjects (64 male and 136 female; mean age 20.29 ± 3.88 years). The data collection tool was a questionnaire including an evaluation of pain expectation for untreated subjects, pain experience for treated subjects, patients' personality profiles and attitudes toward orthodontic treatment. Results: No relationship was found between pain perception, personality traits and patient attitude toward orthodontic treatment (p > 0.05). Treatment status (untreated or treated) affected pain perception and the attitude toward orthodontic treatment (p < 0.05); gender did not affect pain perception. Treatment status and male gender affected patient attitude toward orthodontic treatment (p < 0.05). Conclusions: Patients with a better attitude experienced less pain, whereas patients with a greater pain perception showed a negative attitude. Low levels of kindness have an effect on pain perception and patient attitude toward orthodontic treatment(AU)

ABSTRACT

Introduction: There is a high prevalence of enamel caries around brackets due to the young age of the majority of orthodontic patients, and to the difficulty of plaque removal in presence of orthodontic appliances. Recently, protective agents such as bioactive glasses (BGs) were introduced to enhance remineralization and prevent demineralization of tooth structures. This study aimed to assess the shear bond strength (SBS) of resin-modified glass ionomer cement (RMGIC) with addition of 45S5 BG to enhance its remineralizing potential using two conventional methods. Material and methods: This in-vitro experimental study evaluated three groups (n=20) of orthodontic brackets bonded to enamel using Transbond XT (group 1), light-cure RMGIC (group 2) and RMGIC with BG added (group 3). Samples underwent 7000 thermal cycles and their SBS was measured. The adhesive remnant index (ARI) score was also determined. Quantitative data were analyzed using one-way ANOVA while qualitative data were analyzed using a chi-square test. Discussion: The results showed no significant difference in SBS between study groups, however the ARI scores were significantly different among the groups. The RMGIC group showed the highest ARI while RMGIC doped with BG showed the lowest ARI score. Conclusion: Addition of 30% w/v 45S5 BG to RMGIC does not cause a significant change in SBS of orthodontic brackets bonded to enamel, while resulting in less amount of luting agent remnants on the enamel surface after debonding.


Introducción: Existe una alta prevalencia de caries del esmalte alrededor de los brackets debido a la corta edad de la mayoría de los pacientes de ortodoncia y a la dificultad de remoción de la placa en presencia de aparatos de ortodoncia. Recientemente, se introdujeron agentes protectores como los vidrios bioactivos (VB) para mejorar la remineralización y prevenir la desmineralización de las estructuras dentales. Este estudio tuvo como objetivo evaluar la resistencia al cizallamiento (RC) del cemento de ionómero de vidrio modificado con resina (CIVMR) con la adición de 45S5 BG para mejorar su potencial remineralizante utilizando dos métodos convencionales. Material y Métodos: Este estudio experimentalin vitro evaluó tres grupos (n = 20) de brackets de ortodoncia adheridos al esmalte usando Transbond XT (grupo 1), CIVMR fotopolimerizable (grupo 2) y CIVMR con VB agregado (grupo 3). Las muestras se sometieron a 7000 ciclos térmicos y se midió su RC. También se determinó la puntuación del índice de restos de adhesivo (IRA). Los datos cuantitativos se analizaron mediante ANOVA de una vía, mientras que los datos cualitativos se analizaron mediante una prueba de chi-cuadrado. Discusión: Los resultados no mostraron diferencias significativas en la RC entre los grupos de estudio, sin embargo, los puntajes IRA fueron significativamente diferentes entre los grupos. El grupo CIVMR mostró el ARI más alto mientras que CIVMR dopado con VB mostró el puntaje IRA más bajo. Conclusión: La adición de un 30% p/v de 45S5 VB a CIVMR no causa un cambio significativo en la RC de los brackets de ortodoncia adheridos al esmalte, mientras que resulta en una menor cantidad de remanentes de agente de fijación en la superficie del esmalte después del desprendimiento. Resistencia al Corte.

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 Objective: To assess the possibility of controlling patients at a distance according to principles of teleorthodontics to understand its possible usefulness in the future routine activity and the impact pandemic may have had on different types of orthodontic treatments. Material and Methods: One hundred orthodontic patients (57 F, 43 M, age 7-46) during quarantine were checked through videocalls and photos sent by patients following proper instructions. Three groups have been distinguished based on the type of therapy: A-fixed appliances; B-removable appliances; C-clear aligners. Relevant events about dental and gingival health, integrity of appliances, orthodontic therapies related symptoms and overall progress of treatments were recorded. Results: A and B groups reported higher percentages of gingival inflammation (27 and 22%), dental plaque (16 and 13%), deciduous tooth loss (8 and 16%). Bracket and attachment detachment were the most frequent events in A and C groups (22 and 23%). Pain and discomfort were reported in A and B groups (35 and 32%). Therapies continued to progress better in C (51% improved dental alignment) and B (31% improved malocclusions) groups. Conclusion: Orthodontics is safe and allows during emergencies to postpone checks. Everyday mobile-technology is useful in managing orthodontic patients unable to carry out in-person control. When their effectiveness equals other systems, treatments with clear aligners without attachments should be preferred in patients unavailable for regular checks.

ABSTRACT

L'épidémiologie de la malocclusion et l'évaluation des besoins en traitements orthodontiques sont d'une grande importance. La malocclusion trouve sa grande présence parmi les pathologies orales ; elle est classée troisième après la carie dentaire et la maladie parodontale. Notre étude a eu pour objectif de déterminer la prévalence des anomalies orthodontiques chez une population d'adolescents Casablancais et de dresser les éventuelles associations entre les différentes malocclusions selon les variables âge, sexe et niveau socio- économique. 2183 lycéens âgés de 14 à 18 ans issus de deux lycées Casablancais, tirés au hasard et situés dans deux régions socio économiquement différentes ont été examinés. 81,17% des lycéens examinés ont présenté au moins une malocclusion avec une prédominance de la Classe 1 d'Angle. IMPLICATIONS CLINIQUES: 81,17% des lycéens examinés, au Grand Casablanca ,ont présenté au moins une malocclusion justifiant un besoin important en termes de soins orthodontiques au sein de cette population

ABSTRACT

La atresia o estrechez del maxilar superior es una patología que observamos frecuentemente en nuestra práctica diaria. Es importante el diagnóstico a una edad temprana, no solo para resolver ortopédicamente dicha patología, sino también prevenir una posible cirugía ortognática en la adultez. La expansión palatina rápida es un recurso terapéutico ortopédico para la corrección de la discrepancia transversal esqueletal del maxilar superior, que se manifiesta clínicamente como mordida invertida posterior. Existen diversos tipos de disyuntores y técnicas para su realización. La llegada del anclaje absoluto con los mini-implantes abrió puertas que revolucionan conceptos clásicos de expansión.


Atresia or narrowing of the maxilla is a pathology that we frequently observe in our daily practice. It is important to diagnose at an early age, not only to solve orthopedically this pathology, but also to prevent a possible orthognathic surgery at an adult age. Rapid palatal expansion is an orthopedic therapeutic resource for the correction of the skeletal transverse discrepancy of the maxilla. This pathology manifests clinically as a posterior crossbite. There are different types of expanders and techniques for their realization. The arrival of the absolute anchorage with the mini-implants opened doors that revolutionized classic concepts of expansion

ABSTRACT

Introduction: Maxillary constrictions are one of the most frequent abnormalities, regardless of the type of dentition studied. They can be treated either with tooth-borne or bone-borne expander appliances, depending on the biological maturation of the patient. Treatment during prepubertal stages has been shown to be successful, but there is evidence of an open suture even in late adolescence stages. The aim of this study is to compare the effects of a rapid expansion bone-borne device to a tooth-borne device in young adults suffering from maxillary constriction, by means of Cone-Beam Computed Tomography. Materials and methods: A retrospective observational study was conducted in nine patients (three males, six females) with a mean age of 18±5.5 years, who attended the Dentistry Service of Universidad de Chile during 2014-2015. Six patients were treated with tooth-borne appliances (Hyrax type) and three patients with bone-borne appliances (MARPE). Linear measurements of the anterior and posterior transverse dimension and angular measurements of the inclination of molars and incisors were obtained through CBCT for each group in T1 and T2. Results: A significant increase in the posterior transverse dimensions in both groups was observed. Radiolucency of the suture was observed in all patients treated with miniscrews and in half of the patients treated with Hyrax. Greater angulation of molars was shown in the tooth-borne group in comparison with the bone-borne group. Conclusion: Both appliances caused an increase in the posterior transverse dimension, but bone anchored appliances achieved a more parallel and skeletal expansion. Randomized clinical trials with a larger sample and follow-up are needed.


Introducción: Las compresiones maxilares son una de las anomalías más frecuentes, independiente del tipo de dentición que se esté estudiando. Su tratamiento se puede realizar con un aparato expansor ya sea dentosoportado o esqueletalmente soportado, dependiendo de las consideraciones de maduración biológica del paciente. Se ha demostrado éxito en el tratamiento en etapas prepuberales, sin embargo, existe evidencia de una sutura abierta aún en etapas post adolescencia. El objetivo de este estudio es comparar, mediante Cone Beam CT, los efectos de un dispositivo de expansión rápida maxilar esqueletamente soportado, en relación a los dentosoportados, en adultos jóvenes con compresión maxilar. Material y método: Se realizó un estudio de tipo observacional retrospectivo, donde se evaluaron nueve pacientes (tres hombres y seis mujeres) con un promedio de edad de 18±5,5 años,que asistieron al Servicio de Ortodoncia de la Universidad de Chile, durante los años 2014-2015. Seis pacientes fueron tratados con aparatos dentalmente soportados (tipo Hyrax) y tres pacientes con apartos esqueletalmente soportados (MARPE). A través de CBCT se tomaron medidas lineares de la dimensión transversal anterior y posterior, y medidas angulares de la inclinación de molares e incisivos para cada grupo en T1 y T2. Resultados: Hubo un aumento significativo en la dimensión transversal posterior de ambos grupos. Se presentó radiolucidez de la sutura en un 100% de los pacientes tratados con microtornillos y 50% de los pacientes tratados con hyrax. Hubo mayor angulación de molares en el grupo dentosoportado en comparación al grupo esqueletalmente soportado. Conclusiones: Ambos aparatos lograron un aumento de la dimensión transversal posterior, sin embargo, los de anclaje esqueletal lograron una expansión más paralela y esqueletal. Hacen falta ensayos clínicos aleatorizados con mayor muestra y seguimiento.

ABSTRACT

La mordida abierta anterior esquelética representa un escenario clínico de complejo abordaje para el ortodoncista. Actualmente, existen numerosas alternativas terapéuticas para su manejo, pero aún se tiene escasa evidencia respecto a su efectividad y estabilidad. Este reporte de caso describe el tratamiento de una mujer de 22 años con diagnóstico de mordida abierta esquelética severa que involucraba los dientes anteriores y posteriores hasta el segundo premolar, relación molar bilateral Clase III y mordida cruzada posterior bilateral. El plan de tratamiento consistió en realizar disyunción maxilar asistida quirúrgicamente, SARPE (acrónimo de Surgically Assisted Rapid Palatal Expansion) y posterior manejo con terapia mecánica de arcos multiloop con elásticos, terapia MEAW (Multiloop Edgewise Archwire). Dentro del período de estabilización de la disyunción, se comenzó la mecánica de arcos multiloop con elásticos, con lo que se redujo significativamente la mordida abierta. Después de 14 meses de tratamiento se consiguieron el control vertical y el sagital. La rápida y efectiva evolución de este caso indica que es posible que el procedimiento SARPE provoque aceleración de la terapia ortodóncica, en este caso MEAW, lo que se traduce clínicamente en resultados favorables para la corrección de la mordida abierta(AU)


The anterior skeletal open bite represents a complex clinical scenario for the orthodontist. Currently there are numerous therapeutic alternatives for its management, but there is still little evidence regarding its effectiveness and stability. This case report describes the treatment of a 22year-old woman with a diagnosis of severe skeletal open bite involving anterior and posterior teeth up to second premolar, bilateral Class III molar relationship and bilateral posterior crossbite. The treatment plan consisted of performing Surgically Assisted Rapid Palatal Expansion (SARPE) and subsequent management with mechanical Multiloop Edgewise Archwire therapy with elastics (MEAW therapy). Within the period of stabilization of the disjunction, the mechanics of multiloop arches with elastics was started, thereby significantly reducing the open bite. After 14 months of treatment, vertical and sagittal control was achieved. The speedy and effective evolution of this case indicates that it is possible that SARPE procedure causes orthodontic therapy acceleration, the MEAW therapy in this case, which is clinically translated into favourable results for the correction of the open bite(AU)

ABSTRACT

Abstract Introduction: Various types of separators have been advocated, but the ideal separator should produce optimum separation with minimal pain and discomfort. Objective: The objective of this study was to evaluate and compare the amount of separation achieved by three different types of separators (Elastomeric, Kesling and Kansal), and to assess the associated pain and discomfort. Methods: A random single-blind split-mouth study was conducted on 108 patients seeking fixed orthodontic treatment, in which two different separators were used on each side in both the arches for a single patient. After five days, the amount of separation was measured with a feeler gauge. Visual Analogue Scale (VAS) scoring was performed by the patient on each day, to evaluate pain perception. Discomfort was evaluated by questionnaire filled by the patient at the time of separator removal. Results: The greatest amount of separation was seen with the elastomeric separators, while the smallest separation was seen with Kansal separators. VAS scoring showed maximum pain at day 1 with all the three separator types. Highest pain was perceived in the Elastomeric separators group, followed by Kesling and Kansal separators, respectively. Statistically significant difference was found in VAS score of Elastomeric separators, when compared to both Kesling and Kansal, on day 1 and 2 (p= 0.001). Analysis of the questionnaires revealed that a greater number of patients experienced discomfort with elastomeric separators placement (69.4%), which was statistically significant (p< 0.01) when compared to the other two types of separators. Answers to the other questions were comparable, except for the need for medications, which was reportedly highest with elastomeric separators. Conclusion: Kesling separators produce adequate separation with minimal discomfort and pain, compared to Elastomeric and Kansal separators.


Resumo Introdução: diversos tipos de separadores de dentes já foram descritos e seu uso, justificado na literatura. Porém, o separador ideal deve produzir uma força adequada para realizar a separação com o mínimo de dor e desconforto. Objetivo: o objetivo do presente estudo foi avaliar e comparar a separação ortodôntica obtida por meio de três diferentes tipos de separadores (Elastômeros, Kesling e Kansal), bem como a dor e o desconforto a eles vinculados. Métodos: foi conduzido um estudo randomizado, cego e de boca dividida em 108 pacientes interessados em realizar tratamento ortodôntico, nos quais foram utilizados dois separadores diferentes, um em cada lado de ambas as arcadas de cada paciente. Cinco dias após a inserção dos dispositivos, a quantidade de separação foi mensurada com o auxílio de um medidor (calibrador de folga). Para avaliar a dor, os pacientes preencheram uma Escala Visual Analógica (EVA) a cada dia do estudo; e, para a avaliação do desconforto, preencheram um questionário no dia da remoção dos separadores. Resultados: os Elastômeros obtiveram a maior quantidade de separação, enquanto os separadores Kansal conseguiram a menor separação. A análise das EVAs apontou a maior intensidade de dor no primeiro dia, para os três tipos de separadores, sendo os maiores índices relatados no grupo de Elastômeros, seguido pelos grupos Kesling e Kansal, respectivamente. Diferenças estatisticamente significativas foram encontradas nas escalas EVA dos Elastômeros em comparação aos separadores Kesling e Kandal, nos dias 1 e 2 (p= 0,001). A análise dos questionários mostrou que um grande número de pacientes relatou desconforto após a inserção dos Elastômeros (69,4%), valor estatisticamente significativo em comparação aos outros dois tipos de separadores (p< 0,01). As respostas às outras questões foram semelhantes entre os grupos, com exceção da necessidade de uso de medicamentos, a qual foi maior no grupo dos Elastômeros. Conclusão: os separadores Kesling produziram uma separação adequada, com o mínimo de dor e desconforto, em comparação aos Elastômeros e separadores Kansal.
