Influence of bracket-slot design on the forces released by superelastic nickel-titanium alignment wires in different deflection configurations

Abstract: Bracket design, type of experimental test, and amount of wire deflection significantly affected the amount of forces released by superelastic NiTi wires (P<.05). This phenomenon offers clinicians the possibility to manipulate the wire's load during alignment.

“…The forces released of orthodontic wires follow a diagram represented by a load/deflection graph, which records the amount of force accumulated in each millimeter of deformation (9). Due to the esthetic wire coating, the caliber of the NiTi wire inside the coatings diminished, and this alteration appears to be the variable responsible for the greatest alterations in the mechanical properties of the coated wires (10).…”

“…A temperatura para os testes desta pesquisa também foi baseada na norma ISO 15.841, que indica temperatura de 36±1° Celsius (C), correspondente à temperatura média bucal (AIROLDI et al, 1997;BOLENDER et al, 2010) e, mais especificamente, aos incisivos, cuja temperatura média é de 35°C por cerca de 80% do tempo (LIM et al, 2008;MOORE et al, 1999 KUSY, 2000), e consequentemente aumentando a força do arco, a qual foi registrada através da célula da máquina de ensaio (NUCERA et al, 2014). Esse aumento da força dos fios de NiTi já foi previamente observado em comparações entre as deflexões de 3,5 e 1,5mm em deslocamentos máximos de 4mm (BADAWI et al, 2009;LOMBARDO et al, 2012;MALLORY et al, 2004;NUCERA et al, 2014).…”

Nestes estudos também verificou-se que, clinicamente, este achado poderia ser responsável pelo aumento gradual da força durante a primeira fase de alinhamento e nivelamento dos dentes quando o fio apresentasse um desvio de aproximadamente 4mm (NUCERA et al, 2014 (CORDASCO et al, 2012;MATARESE et al, 2008;KUSY, 2002).…”
