IBC: índice Board CES / The IBC: CES Board Index

Resumen La medición de resultados de los tratamientos de ortodoncia es fundamental para evaluar objetivamente la calidad de la finalización y el éxito logrado por la terapia, y a su vez en la evaluación de los residentes del posgrado de ortodoncia. En la literatura se han reportado varios sistemas que permiten analizar dichos resultados, pero algunos no integran suficientes criterios o ayudas diagnósticas. La Universidad CES, basada en el American Board of Orthodontics-Objetctive Grading System (ABO-OGS), ha desarrollado un índice con 16 criterios analizados en modelos, radiografías y fotografías, que integran una medición objetiva de la finalización de los tratamientos. El propósito de este artículo fue describir el índice Board CES (IBC) como herramienta de evaluación de resultados clínicos de la ortodoncia y generar retroalimentación para el tratamiento de casos futuros mejorando la calidad de los mismos. Dicho índice podría ser empleado en universidades y en prácticas privadas.

The measurement of orthodontic treatment results is crucial to objectively assess the quality of the completion and success of therapy, and in turn in the evaluation of graduate orthodontic residents. The literature has reported several systems that analyze these results, but some do not integrate sufficient criteria or diagnostic aids. CES University, based on the American Board of Orthodontics - Objective Grading System (ABO - OGS), has developed an index with 16 criteria analyzed in models, radiographs and photographs, which allow an objective measurement of the completion of treatments. The purpose of this article was to describe the CES Board Index (IBC) as a tool for assessing clinical outcomes in orthodontics and generate feedback for the treatment of future cases improving their quality. This index could be used in Universities and in private practices.

Quantitative evaluation and affecting factors of post-treatment relapse tendency / 대한치과교정학회지

OBJECTIVE: The purpose of this study was to quantitatively evaluate relapse tendency after orthodontic treatment and determine the contributing factors by using the American Board of Orthodontics objective grading system (ABO-OGS). METHODS: The subjects were 80 patients with more than 2 years of retention period after completing orthodontic treatment at the dental hospitals of Busan University, Kyunghee University, and Dankook University. The posttreatment (T2) and post-retention (T3) ABO-OGS measurements were analyzed in relation to age, gender, Angle's classification, extraction, retention period, and pretreatment condition (initial peer assessment rating (PAR) index, T1) by multiple regression analysis. RESULTS: Among the 7 ABO-OGS criteria, alignment worsened but occlusal contact and interproximal contact improved in T3, but not in T2 (p < 0.01). The 4 other criteria showed no significant differences. Multiple regression analysis showed that alignment, occlusal relationship, overjet, and interproximal contact were significant linear models, but with a low explanation power. Age, gender, Angle's classification, extraction, retention period, and pretreatment condition (initial PAR index, T1) had little influence on the ABO-OGS changes between T3 and T2. CONCLUSIONS: An orthodontist's understanding of post-treatment relapse tendency can be useful in diagnosis and during patient consultation.

Orofacial characteristics in relation to the need of orthodontic treatments in children / Caracteristicas orofaciales en relación a la necesidad de tratamiento ortodóncico en niños

Malocclusion represents a public health problem in Chile. Government policies create preventive and interceptive programs for these conditions. Nevertheless, there are no uniform criteria for the selection of patients who need early treatment; the decision is made by a specialist during orthodontic treatment. Here, we propose the Index for Early Intervention (IEI) for early detection of malocclusions. We treat malocclusions with a simple interceptive treatment to minimize or eliminate the need for orthodontic treatment in a child population. Furthermore, the IEI can be used in general dentistry as a screening method. The purpose of this study was to compare the reliability and validity of an index used to assess the need for orthodontic treatment, as compared to the view of a panel of experts formed by three orthodontists. We used a set of 55 study casts representing all types of malocclusion. The accuracy of the diagnostic or the validity of each index was calculated using the opinions of three orthodontic raters as a “gold standard;” these measures obtained an agreement of 0.82. Receiver Operating Characteristic curves was plotted for the index. Results: Diagnostic accuracy was determined by the area under the curve, the cut point was 20, sensitivity was 0.977 and specificity was 0.167. Conclusions: This occlusal index provided valuable information for selecting children in need of early and simple orthodontic treatment.

La maloclusión representa un problema de salud pública en Chile. Políticas del Gobierno han creado programas preventivos e interceptivos para estas condiciones. Sin embargo, no existen criterios uniformes para la selección de los pacientes que necesitan tratamiento temprano, la decisión es tomada por un especialista durante el tratamiento ortodóncico. Aquí, proponemos el índice de Intervención Temprana (IIT) para la detección temprana de maloclusiones. Tratamos maloclusiones con un simple tratamiento de intercepción para minimizar o eliminar la necesidad de un tratamiento de ortodoncia en una población infantil. Además, el IIT puede ser utilizado en odontología general como un método de tamizaje. El objetivo de este estudio fue comparar la confiabilidad y validez de un índice utilizado para evaluar la necesidad de un tratamiento de ortodoncia, en comparación con la opinión de un panel de expertos formado por tres ortodoncistas. Se utilizó un conjunto de 55 modelos de estudio que representan todos los tipos de maloclusión. La precisión del diagnóstico o la validez de cada índice se ha calculado utilizando lasopiniones de tres calificadores de ortodoncia como un "gold standard", estas medidas obtuvieron un acuerdo de 0,82. Las curvas de las características operativas del receptor fueron trazadas para el índice. La precisión diagnóstica fue determinada por el área bajo la curva, el punto de corte fue de 20, la sensibilidad fue del 0,977 y la especificidad fue del 0,167. Este índice oclusal proporcionó información valiosa para la selección de los niños que necesitan un tratamiento de ortodoncia temprano y simple.

Avaliação pelo índice PAR dos resultados do tratamento ortodôntico da má oclusão de Classe I tratada com extrações / PAR evaluation of orthodontic treatment outcomes of Class I malocclusion cases treated with extraction

INTRODUÇÃO: torna-se difícil, sem a utilização de um índice oclusal, uma avaliação fidedigna dos resultados e da finalização dos tratamentos ortodônticos. O índice PAR é capaz de avaliar objetivamente as alterações que ocorrem com o tratamento ortodôntico, e as melhorias conseguidas. OBJETIVO: por isto, decidiu-se, neste estudo, avaliar-se as alterações decorrentes dos tratamentos ortodônticos realizados com aparelho fixo, mecânica Edgewise e com extrações dos quatro primeiros pré-molares, bem como a qualidade de sua finalização e de seus resultados, por meio do índice de avaliação oclusal PAR. MATERIAL E MÉTODOS: foram avaliados os modelos de estudo de 94 pacientes leucodermas, com idade média de 13,46 anos, sendo 50 do gênero masculino e 44 do feminino. O tempo de tratamento médio foi de 2,09 anos. O índice PAR foi obtido dos modelos pré e pós-tratamento de cada um dos pacientes. RESULTADOS: após a realização da análise estatística descritiva, pode-se observar que o índice PAR inicial médio de 29,46 foi reduzido para 6,32 ao final do tratamento, caracterizando uma redução de 78,54 por cento com o tratamento ortodôntico. Houve correlação do índice PAR inicial com a correção deste índice durante o tratamento. CONCLUSÃO: pode-se concluir que os casos tratados demonstraram um bom padrão de finalização ortodôntica, e quanto maior a severidade da má oclusão, maior a correção com o tratamento.

INTRODUCTION: a trustworthy evaluation of orthodontic treatment outcomes without using an occlusal index becomes difficult. The PAR index is capable of objectively assess treatment changes and the real improvement. OBJECTIVE: due to this, it was decided to evaluate orthodontic treatment changes with fixed appliances, Edgewise mechanics and four premolars extractions, as well as the quality of finishing occlusion, using the PAR index. MATERIAL AND METHODS: study casts of 94 white patients (50 males and 44 females) were evaluated. The mean pre-treatment age was 13.46 years and the mean treatment time was 2.09 years. The PAR index was obtained from pre-treatment and post-treatment study casts of each patient. RESULTS: after the accomplishment of statistical analysis, it could be observed that the mean initial PAR index of 29.46 was reduced to 6.32 at post-treatment stage, achieving a reduction of 78.54 percent with treatment. There was correlation between the initial PAR index and correction during treatment. CONCLUSION: it could be concluded that the treated cases presented a high standard orthodontic finishing, and the more severe the malocclusion, the more will be the treatment changes.
