“…Celikoglu et al 15 compared the effects of self-ligating vs conventional brackets on transverse expansion of the mandibular arch when using 0.014-inch NiTi wires. After 8 weeks of treatment with 0.014-inch NiTi, they found 0.87 mm expansion in mandibular intercanine width in the selfligating group and 0.59 mm expansion in the conventional bracket group.…”

Objectives: The purpose of this prospective, double-blind, randomized clinical trial was to compare the clinical efficiency of nickel-titanium (NiTi) and niobium-titanium-tantalum-zirconium (TiNbTaZr) archwires during initial orthodontic alignment. Materials and Methods: All subjects (ages between 12 and 20 years) underwent nonextraction treatment using 0.022-inch brackets. All patients were randomized into two groups for initial alignment with 0.016-inch NiTi archwires (n ¼ 14), or with 0.016-inch TiNbTaZr archwires (n ¼ 14). Digital scans were taken during the course of treatment and were used to compare the improvement in Little's Irregularity Index and the changes in intercanine and intermolar widths. Results: There was approximately a 27% reduction in crowding during the first month with the use of 0.016-inch TiNbTaZr (Gummetal) wire, and an additional 25% decrease in crowding was observed during the next month. There was no significant difference between the two treatment groups in the decrease in irregularity over time (P ¼ .29). There was no significant difference between the two groups in the changes in intercanine and intermolar width (P ¼ .80). Conclusions: It can be concluded that Gummetal wires and conventional NiTi wires possess a similar ability to align teeth, and Gummetal wires have additional advantages over conventional NiTi, such as formability and use in patients with nickel allergy.

“…Celikoglu et al 15 measured the change in irregularity in the mandibular anterior segment over 8 weeks when using 0.014-inch NiTi with both conventional and self-ligating brackets. They found that irregularity decreased by 3.84 mm in the self-ligating group and by 2.93 mm in the conventional ligation group.…”

“…The custom jig used in the present study fixed the archwire at the mean first molar depth and width because the results of RCTs showed a nonsignificant or absent change at the first molar during alignment. 15,17 However, further methods of locating the first molar tubes should be considered in future studies.…”

“…9 However, recent randomized clinical trials (RCTs) that evaluated changes in mandibular dental arch form found significant arch expansion in the early stages of orthodontic treatment, despite the bracket type or archwire form. [15][16][17] Certain authors have stated that the reason for the dimensional change during the alignment phase is the inconsistency between the manufactured archwire forms and the natural diversity of the human dental arch form. Results of the mentioned RCTs [15][16][17] indicated the necessity of investigating arch form variation among light, round, preformed NiTi archwires.…”

Objective: To evaluate the variation in form of nickel-titanium (NiTi) archwires by comparing them with the dental arch form of normal Japanese subjects before and after placing them in the first molar tubes. Materials and Methods: The mandibular dental casts of 30 normal subjects were scanned, and the dental arch depths and widths from the canine to the first molar were measured. Standardized images of 34 types of 0.016-inch preformed NiTi archwires were also taken in a 37uC environment, and the widths were measured and then classified by cluster analysis. Images of these archwires placed in a custom jig with brackets attached at the mean locations of the normal mandibular central incisors and first molar were additionally taken. The widths of the pooled and classified archwires were then compared with the normal dental arch widths before and after placement in the jig and among the groups (P , .05). Results: The archwires were classified into three groups: small, medium, and large. The archwire widths in the small and medium groups were narrower than those at all examined tooth widths, except in the case of the premolars of the medium group. After placement in the jig, the pooled archwire widths were found to be significantly narrower and wider at the canine and second premolar, respectively, than at the dental arch, but not in the individual comparisons between groups. Conclusion: The variation observed in the mandibular NiTi archwire forms significantly decreased following fitting into the normal positions of the first molars. (Angle Orthod. 2016;86:796-803.)

Aims: The aims of the present study were to investigate rate of mandibular incisors alignment, levels of IL-1β and pain and discomfort during orthodontic alignment with the following: 1) conventional-ligating appliance (CLA); 2) self-ligating appliance (SLA); 3) self-ligating appliance combined to vibrational appliance (SLA-VA). Methods: This was a three-armed parallel group randomized clinical trial with allocation ratio 1:1:1. The main inclusion criteria were: full permanent dentition, age below 25 years, no missing teeth, first skeletal and molar class, non-extraction treatment, Little's Irregularity Index (LII) from 3mm to 6mm. The main outcomes were rate of mandibular incisors alignment, concentration of IL-1β and pain and discomfort. Measurements on models were performed at appliance placement (t0) and at monthly intervals for the first 3 months (T1, T2, T3), whereas IL-1β levels were measured at weekly intervals for the first 3 weeks (t1, t2, t3). Differences between groups for normally-distributed variables were initially estimated through Analyses of Variance (ANOVAs) tests, followed by Post-Hoc Scheffe analysis for pair wise comparisons. Results: Thirty-three patients were recruited and randomized with no lost to follow-up. During the first two months, faster alignment was observed for SLA (P=0.0491) and SLA-VA (P=0.0134) compared to CLA. At each time-point of measurement no differences were observed between SLA and SLA-VA. At t1 and t2 were found higher values of IL-1β for SLA-VA compared to SLA (P=0.0209, P=0.0352) and CLA (P=0.0018, P=0.0029), whereas at t3 the difference persisted only versus CLA (P=0.0304). No relevant differences in terms of pain and discomfort were observed between groups at any time point. Conclusions: Self-ligating appliances seem to perform better than conventional-ligating appliances in terms of timing of teeth leveling and alignment. Vibrational devices seem to enhance secretion of IL-1β but do not increase effectiveness of leveling and alignment with regard to treatment acceleration or pain reduction.
