Abstract:

Orthodontic tooth movement is a physiologic response to externally applied forces; the motive forces are primarily mechanical. The optimal application of orthodontic force enables maximum movement of teeth with minimal irreversible damage of the periodontal ligament (PDL), alveolar bone, and teeth. Since arch wires are the main force system in orthodontics, it is important in clinical practice that they deliver appropriate, predictable and repeatable forces during treatment. These specialized wires even promise shape memory properties and the possibility of super elastic behavior, which signif

Abstract:

Recent advances in orthodontic wire alloys have resulted in a varied array of wires that exhibit a wide spectrum of properties. Appropriate use of these wires may enhance the patient comfort; reduce the chair side time and duration of the treatment. Though superior materials and techniques are now available and many replace conventional methods, one should keep in mind that no arch wire is ideal or best for all stages of treatment. Since arch wires are the main force system in orthodontics, the knowledge about newer arch wires will help us to select the appropriate wire within the context of t

NiTi shape memory alloy is widely used in dental applications such as orthodontics arch wire, mini screw implant, orthodontics spring, etc., because of its favorable superelasticity and shape memory effect. Wire drawing is a fundamental manufacturing process used for producing orthodontics arch wires. It is well known that cold-work occurred during wire drawing operation is also important to control mechanical properties and transformation temperature of NiTi wires. Thus, the purpose of this work is to study the effect of cold working by means of reduction ratio of cross -sectional area and he

The orthodontic minitubes system (FLOWJAC ® System, Bogotá, Colombia) is an innovating system that blend the selfligating philosophy techniques and a lowprofile appliance. The FLOWJAC® System works with low orthodontic forces, same as selfligation devices. The system uses heat-treated wires with better physical properties such as hysteresis when is compare with traditional wires. However, the FLOWJAC® technique doesn´t use a wire sequence to get a “working wire”, just a 0,014 Copper NiTi. The clinician in each appointment must modify the minitube location to the clinical desire teeth position.

Aim: This case report demonstrates the application of piezocision in correcting persistent crowding in the lower anterior region of dental arch. Methodology: A female aged 14 years and 3 months presented to the Selcuk University Department of Orthodontics due to aesthetic complaints. Clinical and radiological examination revealed crowding in the upper and lower dental arches as well as skeletal and dental Class I malocclusion. First, bonding and arch wire were applied to the patient’s upper jaw. The patient then had check-up appointments at 4-week intervals. In the second session, bondin

Objective: The study aimed to clarify the compositions of 14 brands of superelastic NiTi orthodontic wires. Materials and Methods: The compositions were analysed through scanning electron microscopy and energy-dispersive X-ray microanalysis. The wires were tested in differential scanning calorimetry to find the transitional temperature range. Results: The compositions were nickel (50.085%-51.605%), titanium (46.675%-48.140%), copper (0.995%-1.155%), aluminum (0.220%-1.325%), chromium (0%-0.275%) and iron (0%-0.030%).

ABSTRACT Introduction There exist a number of factors that affect the outcome of orthodontic treatment. These factors can be assessed by various gingival markers. One such maker is myeloperoxidase (MPO). Hence, we planned the present study to assess and compare the MPO activity in the gingival crevicular fluid (GCF) of subjects undergoing orthodontic treatment by different aligning arch wires. Materials and methods The present study included assessment of patients who underwent orthodontic treatment for crowding of anterior teeth.

Abstract:

Abstract Most previous studies of archwire deformation over time (hereafter referred to as “time-dependent deformation of orthodontic wires”) have been conducted at a constant room temperature. In the clinical situation however, arch wires are exposed to 37°C as well as to periods of temperature increase when hot foods or fluids are ingested. The effects of the latter on time-dependent behaviour are largely unknown. Since the introduction of direct electric resistance heat treatment to superelastic nickel titanium wires, there have been no reports on its effect on time-dependent deformation. T

Abstract:

The surface roughness of orthodontic archwires is an essential factor that deter- mines the effectiveness of arch-guided tooth movement. CuNiTi-based wires are widely used in orthodontic treatment, but the oral environment can trigger corrosion of CuNiTi orthodontic wires. The tannin content in avocado seed extract can be used as a corrosion inhibitor through two working mechanisms, namely, forming a passive layer and an adsorption process. The aim of this research is to examine the effect of avocado seed extract as a corrosion inhibitor on the surface roughness of orthodontic CuNiTi wire. The

<strong>Abstract</strong><strong>—</strong> The demands for orthodontic treatment are in continuous increasing, hence producing an ideal treatment plan need to cover all stages of the treatment carefully, especially the retention and stabilization stage. As, any changing in the arch width through changing the inter-molar width will lead to impair the stabilization of the arch and will lead to relapse. Due to that, the present study performed to evaluate the inter-molar width of the mandible using three different commercial orthodontic wires. Thirty patients had been allocated in this stu
