ABSTRACT

ABSTRACT Objective: To evaluate the results of a finishing protocol implemented in patients treated in the Orthodontics graduate program at Universidad de Antioquia. Evaluation was carried out by means of the criteria set by the Objective Grading System (OGS) of the American Board of Orthodontics (ABO). Methods: Cast models and panoramic radiographs of 34 patients were evaluated. The intervention group (IG) consisted of 17 patients (19.88 ± 4.4 years old) treated under a finishing protocol. This protocol included training in finishing, application of a finishing guide, brackets repositioning and patient's follow-up. Results of the IG were compared to a control group of 17 patients (21.88 ± 7.0 years old) selected by stratified randomization without finishing intervention (CG). Results: The scores for both CG and IG were 38.00 ± 9.0 and 31.41 ± 9.6 (p = 0.048), respectively. The score improved significantly in the IG group, mainly regarding marginal ridges (CG: 5.59 ± 2.2; IG: 3.65 ± 1.8) (p = 0.009) and root angulation (CG: 7.59 ± 2.8; IG: 4.88 ± 2.6) (p = 0.007). Criteria that did not improve, but had the highest scores were: alignment (CG: 6.35 ± 2.7; IG: 6.82 ± 2.8) (p = 0.62) and buccolingual inclination (CG: 3.6 ± 5.88; IG: 5.29 ± 3.9) (p = 0.65). Conclusions: Standardization and implementation of a finishing protocol contributed to improve clinical performance in the Orthodontics graduate program, as expressed by occlusal outcomes. Greater emphasis should be given on the finishing phase to achieve lower scores in the ABO grading system.


RESUMO Objetivo: avaliar os resultados da implementação de um protocolo de finalização em pacientes tratados no programa de pós-graduação em Ortodontia da Universidad de Antioquia. A avaliação foi conduzida utilizando-se os critérios definidos pelo Objective Grading System (OGS) do American Board of Orthodontics (ABO). Métodos: modelos de gesso e radiografias panorâmicas de 34 pacientes foram avaliados. O grupo experimental (GE) consistiu de 17 pacientes (idade média = 19,88 ± 4,4 anos) submetidos a um protocolo de finalização que incluiu o treinamento para a etapa de finalização, a aplicação de um guia de finalização, o reposicionamento de braquetes e o acompanhamento dos pacientes. Os resultados obtidos para o GE foram comparados aos resultados de um grupo controle (GC), não submetido à etapa de finalização, composto por 17 pacientes (idade média = 21,88 ± 7,0 anos) selecionados por um método de amostragem aleatória estratificada. Resultados: os escores do GC e do GE foram de 38,00 ± 9,0 e 31,41 ± 9,6 (p = 0,048), respectivamente. Houve melhora significativa no escore do grupo GE, principalmente com relação às cristas marginais (GC = 5,59 ± 2,2; GE = 3,65 ± 1,8) (p = 0,009) e à angulação da raiz (GC = 7,59 ± 2,8; GE = 4,88 ± 2,6) (p = 0,007). Os critérios que não apresentaram melhora, mas obtiveram os escores mais altos, foram: alinhamento (GC = 6,35 ± 2,7; GE = 6,82 ± 2,8) (p = 0,62) e vestibularização (GC = 3,6 ± 5,88; GE = 5,29 ± 3,9) (p = 0,65). Conclusões: a implementação de um protocolo padronizado de finalização contribuiu para melhorar o desempenho clínico dos alunos em um programa de pós-graduação em Ortodontia, conforme demonstram os resultados oclusais. Maior ênfase deveria ser dada à fase de finalização, para se obter escores mais baixos no OGS do ABO.

ABSTRACT

Este estudio descriptivo evalúa los resultados clínicos estáticos de los tratamientos finalizados en el Posgrado de Ortodoncia de la Universidad de Antioquia durante el periodo 2010-2011 y su relación con la complejidad inicial y otros factores administrativos. A los pacientes terminados se les realizó un seguimiento documental de la historia clínica para determinar el grado de compromiso inicial y se evaluaron, con los parámetros del Objective Grading System (OGS) del American Board of Orthodontic (ABO), los modelos y las radiografías panorámicas finales. De 99 pacientes que terminaron el tratamiento, 40 cumplieron los criterios de inclusión. El 80% de los pacientes que terminaron el tratamiento tenían maloclusión comprometida o altamente comprometida al iniciar. El puntaje OGS del ABO encontrado fue en promedio de 31,7(±8,5) puntos y el 50% de los casos pasaban los criterios del OGS. El tiempo de duración del tratamiento (55±22,25 meses) y el número de citas promedio para terminar el tratamiento (37,3±11,4) aumentan según la complejidad de la maloclusión inicial. El grado de maloclusión inicial tuvo relación estadísticamente significativa con los puntajes de OGS (p=0,018), mientras que otras variables administrativas y clínicas no afectaron los resultados. Los valores finales del OGS encontrados no son los ideales y son afectados por el compromiso de la maloclusión.


This descriptive study assessed the clinical static results of the treatment finished in the orthodontic graduate clinics of the University of Antioquia during the years 2010-2011, and its relationships with initial malocclusion complexity and some administrative factors. The records and complete medical histories of the patients were reviewed to determine the degree of initial malocclusion commitment and the final panoramic radiography and plasters were evaluated applying the Objective Grading System (OGS) proposed by the American Board of Orthodontic (ABO). Of 99 patients who completed treatment, 40 met the inclusion criteria. 80% of patients, who completed treatment, started with committed or highly committed malocclusion. The ABO OGS score found an average of 31.7 (±8.5) and 50% of the cases approved OGS criteria. The duration of treatment (55±22.25 months) and the average number of appointments to complete treatment (37.3±11.4) increased with the complexity of the initial malocclusion. The degree of initial malocclusion had statistically significant relationship with OGS scores (p=0.018), while other administrative and clinical variables did not affect the results. The final values of OGS found are not ideal and are affected by the complexity of the initial malocclusion.
