“…Unrealistic force variants at which plateau levels are reached in the stressstrain curve of NiTi wires could be another reason. Evans et al 7 found no statistically significant difference in alignment capabilities of medium force active martensitic rectangular NiTi wire, multistranded stainless steel wire, and graded force active martensitic NiTi wire. However, for studying the alignment capabilities of the anterior segment of the arch, investigators had included upper and lower anterior segments together.…”

“…2 Clinical trials conducted to assess the alignment efficiency of these archwires failed to demonstrate any significant advantage of any particular wire in overall alignment of the arches. [3][4][5][6][7][8][9][10][11] Multistranding of archwires to gain mechanical advantages such as increased flexibility and a reduced load deflection rate has been successfully attempted with the use of stainless steel. [12][13][14][15] The same concept was applied in the case of superelastic NiTi by Hanson (cited by Berger and Waram 16 ); this led to the introduction of Supercable, a seven-stranded round coaxial superelastic NiTi archwire.…”

Objective: To clinically evaluate the alignment efficiency of 0.016-inch coaxial superelastic nickeltitanium (NiTi) and 0.016-inch superelastic NiTi in the lower anterior region over a period of 12 weeks. Materials and Methods: A sample of 24 patients requiring lower anterior alignment were included in this single-center, single-operator, double-blind clinical trial and were randomly allocated into two groups of 12 patients. The type of wire selected for each patient was not disclosed to the provider or to the patient. Comparison of pretreatment characteristics of the archwire groups revealed no discrimination between two samples, thus verifying the random allocation of the intervention. An initial alginate impression of the lower arch was followed by impressions at 4-, 8-, and 12-week intervals. Casts were measured using the coordinate measuring machine to denote the degree of alignment. Duplicate readings of the cast series were taken to assess measurement variation. Results: A statistically significant difference (P , .05) in the mean values of tooth movement demonstrated the superior aligning efficiency of coaxial superelastic NiTi over single-stranded superelastic NiTi in relieving lower anterior crowding. The measurement error recorded was within acceptable limits, with range values within 95% limits of agreement. Conclusion: Coaxial superelastic NiTi wire proved superior to single-stranded NiTi in its efficiency in relieving lower anterior crowding over a 12-week period. (Angle Orthod. 2012;82:703-708.)

“…Some studies compared archwires with each other and some studies compared archwire sequences instead of comparing initial archwires (14)(15)(16)(17)(18)(19)(20)(21)(22). Based on the studies on archwire sequences, when there is a significant difference between two sequences, it is more difficult to determine which wire or wires of that particular sequence was or were more effective and led to a significant difference.…”

“…As mentioned before, multi-stranded SS wires can also be the choice for the alignment phase. Researches have shown that their use is as successful as that of nickel-titanium at the time of initial alignment (13,18).…”

The key to a successful orthodontic therapy depends not only on manual skills and knowledge about treatment steps, but also on knowledge and choice of materials used. One of the major components of fixed orthodontic therapy is the choice of wires. Orthodontic wires are defined as devices consisting of a wire conforming to the alveolar or dental arch, used as an anchorage in correcting irregularities in the position of the teeth. The history of these materials is as old as that of fixed orthodontic treatments and they present different features. With proper general knowledge, doctors can differentiate between wires and use the sufficient wire sequence suitable for each patient. This can increase the quality of treatment. Therefore, the aim of the present review is to focus on the differences in features of wires as well as the sequence of leveling wire selection according to the treatment plan.
