“…According to the current results and previous publications, the first wire to favor seems to be the 0.014-inch CuNiTi 27, correcting malocclusion up to 3 mm. 30,31 Montasser et al had previously noticed that even a 0.014-inch wire caused high forces. 21 Smaller diameters could be beneficial especially for CuNiTi 35.…”

Objectives To assess the super-elasticity of CuNiTi wires (Ormco, Glendora, Calif) according to their Austenite finish temperature (Af) and to the imposed displacement. The secondary objective was to compare the wire dimensions with the stated measurements and to study interbatch variability. Materials and Methods 10 types of CuNiTi wires (Ormco, Glendora, Calif) (n = 350) were investigated at 36 ± 1°C, with conventional brackets (Victory Series, 3M Unitek, Monrovia, Calif). Tensile test with coronoapical displacement ranging from 1 to 5 mm of the canine bracket was imposed. The wire dimensions were initially measured from two batches (n = 10). Results Dimensional heterogeneity varied by ± 2.00% compared to the manufacturer's data, and even up to 5.54% for 0.014-inch CuNiTi (P = .00069). However, all unloading forces were reproducible. In decreasing order, the forces delivered by a CuNiTi 27 were greater than those with CuNiTi 35 and 40. The super-elasticity was expressed only for displacements of 1 to 2 mm, at best up to 3 mm for 0.014-inch CuNiTi 27. Conclusions The value of Af as well as the amount of imposed displacement seem to influence the expression of the super-elasticity of CuNiTi wires and the amount of corrected malocclusion. Among the tested wires, under these experimental conditions, 0.014-inch wire could be suitable as a first archwire. CuNiTi 35, therefore, seems to offer the best compromise among the force level, the expression of super-elasticity and the amount of malocclusion correction.

“…1 Prolonged orthodontic management prods a lot of patients, Orthodontists are trying since long to develop certain approach strategies that will actually assist to increase the rate at which the tooth movement takes place during orthodontic treatment. 2,3 The rate of tooth movement per se can be accelerated by administration of drugs such as prostaglandins, electrical stimulations, vitamin D and osteocalcin, use of ultrasound around the sockets in the jaws. The injection method is always accompanied by certain degree of pain as well as discomfort to the patients.…”

To assess the acceleration of tooth movement in canine retraction and to assess the interleukin 1β level in Gingival Crevicular Fluid. 0.022 slot MBT brackets, 0.018 inch stainless steel arch wire, Low level laser (Gallium-Aluminium-Arsenide Laser), ELISA kit, Micro-capillary tube, Digital Vernier calliper, Dontrics gauge, NiTi closed coil springs Open labelled split mouth, non-experimental interventional institutional based study. By coin toss method, each of the participant’s mouth was randomly assigned either to the laser therapy (group 1) and 40 reference sites (group 2). On the experimental site orthodontic treatment with fixed appliance, a combination with low level laser therapy (Gallium-Aluminium-Arsenide laser) to the canine on the days 3,7,14 and then every 15 days for 2 months was initiated. Then 5µL of Gingival Crevicular Fluid (GCF) was collected to analyse the interleukin 1β levels using the ELIZA kit. The measurements were made with the help of a digital Vernier calliper. The laser group showed a significant greater reduction in the canine to molar distance than the site treated with conventional technique. The interleukin 1 β levels raised significantly for the site treated with laser as compared to the other. We observed that: Increased inflammatory response in the form of raised interleukin levels and Faster distalization of the canine when adjunct with low level soft tissue laser. The entire data was statistically analyzed using Statistical Package for Social Sciences (SPSS version 21.0, IBM Corporation, USA) for MS Windows. In Statistics, unpaired t-test is a used to compare equality of two population means and F-test is used to compare the equality of two population variance using that the samples were drawn from different populations. There was a clinically appreciable amount of retraction seen resulting in faster space closure between the canine and the first permanent molar in the group that had low level laser than the other group that was treated by the conventional therapy. We also observed a considerable rise in the interleukin 1 β levels in the laser group.
