Abstract

Objectives: This study aimed to evaluate the load deflection properties of new niobium-based beta
titanium archwire (Gummetal) in comparison with superelasticnickel titanium (SE-NiTi) and copper
NiTinickel titanium (Cu-NiTi) archwires.

Methods and Material: Gummetal, superelasticNiTiand copper NiTiarchwire segments of 0.014-inch
diameter were examined by three point bending test, using Instron testing machine with 10 Newton (N)
load cell. Wire segments were tested at 2 and 4 mmdeflections, and at a temperature of 37±1ᵒC. Oneway analysis of variancewas used to compare the means of the groups at a significance of p ˂ 0.05.
Results: At 2 mm deflection, the maximum force values and unloading forces of Gummetalwere
significantly higher than those of the control (SE-NiTi and Cu-NiTi) archwires. At 4 mm deflection,
there was no significant difference between the maximum force values of Gummetal and SENiTiarchwires, however they were significantly higher than those of Cu-NiTiarchwire. Unloading forces
of Gummetalarchwire at 4 mmdeflection were initially significantly higher, then became significantly
lower than the control wires at 1 mm unloading deflection point.
Conclusions: The present study showed that Gummetalarchwirewas less efficient in providing
continuous forcesin comparison with SE-NiTi and Cu-NiTiarchwires.Gummetalarchwire cannot be
considered superelastic, and its use in the alignment phase may better be limited to mild crowding
cases.
