“…The rounded arch slot walls of Synergy brackets, which were used in our study, reduce BI and FR, which is important for efficient management of sliding between the archwire and bracket during the levelling phase (22). In this study, when the elastomeric ligation was tied onto the inner tie wings of the Synergy brackets, free movement of the archwire in the bracket slot was enabled (passive ligation design) (2,(15)(16)(17); consequently, frictional force was reduced. However, at high vertical displacements, such as 3 mm, the Synergy brackets had higher F/O force ratios.…”

“…When the elastomeric ligation is tied on the inner tie wings of the brackets, the bosses prevent the ligation from contacting the archwire. Synergy brackets have a passive ligation design (i.e., no ligation force is exerted on the archwire) (2,(15)(16)(17).…”

“…Os bráquetes ativos testados mostraram resistência com valores variando de 12 a 54 cN e os passivos igual a zero ou inexistente 17 . Montasser et al 18 , em 2013, recomendou os arcos de 0,012" termoativados para a fase de alinhamento inicial. 18 Em 2015, este mesmo grupo de autores 19 , em outro estudo, avaliou o diâmetro do fio e concluiu que aumentando-se a secção transversal do fio, eleva-se os níveis de força, para os AL e BC, invariavelmente 19 .…”

ResumoA evolução sistemática dos materiais ortodônticos impulsiona uma contínua inovação tecnológica com o objetivo de potencializar a biocompatibilidade dos tratamentos, tornando-os constantemente mais simples e eficientes. Mas, apesar de todo conteúdo publicado em revistas especializadas sobre os bráquetes autoligáveis (AL), o tema ainda é motivo de controversia, sobretudo mediante comparação da eficiência com os bráquetes convencionais (BC). Desse modo, o objetivo dessa revisão é fornecer embasamento científico para a utilização desses acessórios na rotina ortodôntica. Descritores: Movimentação Dentária; Desenho de Aparelho Ortodôntico; Fechamento de Espaço Ortodôntico. AbstractThe systematic evolution of orthodontic materials encourages a continuous technological innovation in order to enhance the biocompatibility of treatments, making them constantly simpler and more efficient. Nevertheless, despite all contents published in specialized periodicals on self-ligating brackets (SL), the subject is still a controversial matter, especially by comparing the efficiency with conventional brackets (CB ). Thus, the objective of this literature review bases on providing scientific basis for the use of these accessories in orthodontic routine.

“…Recently, force magnitudes of nickel-titanium alloy archwires with different ligation methods have been compared using a modified three-point bending test. Brackets were bonded to a metal block [6][7][8] or resin formed model 9,13) and the force from the ligated and deflected nickel-titanium alloy archwires were measured at a single point. Significant differences in the force magnitude from the archwire were found when using a stainless steel ligature, elastic module, and the self-ligating method [6][7][8]13) .…”

The present study investigated the influence of archwire size and ligation method on the force magnitude delivered by nickel-titanium alloy archwires to 4 incisor brackets (42, 41, 31, and 32) in a simulation of mandibular right lateral incisor linguoversion. The force delivered by 0.014 and 0.016 inch nickel-titanium alloy archwires was measured using a newly developed multi-sensor measuring system and the mean force magnitudes were compared between different archwire sizes when using conventional ligation (CL) with elastic modules or self-ligating (SL) brackets by three-way ANOVA and post-hoc Bonferroni's tests. The mean force magnitudes for the brackets were significantly decreased in the order of 42, 41, 31, and 32 (p<0.01). The force magnitude was significantly larger in CL than SL at 42, 31, and 32 (p<0.05). In conclusion, the ligation method affected the force magnitude at 4 incisor brackets. Despite the ligation method, archwire size affected the force magnitude from 42 to 31.
