Clinical comparisons of different fixed orthodontic retainers

Abstract

Objective: The aim of this prospective clinical study was to compare the clinical outcomes of three different fixed lingual retainers, in terms of effects on periodontal health and success rate. Methods: Forty five patients aged 13 to 25 years were randomly assigned into three groups, using bonded upper and lower lingual retainers. The study groups were as follows: Group 1- Bond-A-Braid®, Group 2- everStick® ORTHO, Group 3- Super-Splint. The follow-up appointments were performed two weeks (Baseline=T0), one month (T1), three months (T2), and six months (T3) after the application of retainers. Plaque Index (PI), Gingival Index (GI), Probing Depth (PD), Bleeding in Probing (BOP) and Retainer Failure were assessed at each appointment. Results: The everStick Ortho group showed significantly lower PI values on the upper-lower lingual side after three (p=0.008) and six (p=0.001) months. The everStick Ortho group had significantly lower upper lingual (GI) levels after six months, and lower lingual side levels after one month. The Super-Splint group showed significantly lower PD values on the upper lingual side after six months. The everStick Ortho group presented significantly lower BOP levels after six months on the upper lingual side. No significant differences between the groups (p>0.05) in terms of retainer failure were found. Conclusions: The everStick Ortho group presented better results in terms of periodontal health. The failure rates of the retainers were similar.

Comparación de la velocidad de alineación entre la ortodoncia fija lingual versus labial. Revisión de literatura

“…Sin embargo, la ortodoncia lingual demuestra algunas dificultades en el tratamiento, una de ellas es la velocidad y tiempo del procedimiento, debido a la utilización de los tipos de Brackets, esto representa una preocupación latente por parte de los pacientes por el tiempo de utilización de los aparatos ortopédicos (7). A su vez, los retenedores linguales fijos presentan problemas de rendimiento en cuanto al tiempo de uso, por ello, es necesario analizar el mejor tipo de retenedores para una aparatología fija lingual (9). www.anatomiadigital.org uso de la aparatología lingual, puesto que, no se han realizado suficientes estudios a profundidad sobre la temática de la velocidad de la aparatología lingual-labial durante los últimos cinco años.…”
