Open-Coil Retraction Spring
Sliding mechanic has become a popular method for space closure with developments in preadjusted edgewise appliance. Furthermore, various space closing auxiliaries have been developed and evaluated extensively for their clinical efficiency. Their effectiveness enhanced with optimum force magnitude and low-load deflection rate (LDR)/force decay. With the advent of NiTi springs in orthodontics, LD...
متن کاملthe effects of aging process and preactivation on mechanical properties of nickel-titanium closed coil springs
background: the most favorable feature of nickel-titanium (ni-ti) alloys in orthodontics is producing constant forces in a wide deformation range. ni-ti closed coils produce compressive strength and can be used for several purposes such as space closure. the aim of this study was to evaluate the effects of the aging process (temperature changes and prolonged strain) on ni-ti closed coils and to...
متن کاملPentraxin-3 Levels in Gingival Crevicular Fluid during Canine Retraction with NiTi Coil Spring and Active Tieback
Aim: Orthodontic treatment is routinely carried out in patients with the purpose of correcting various forms of dental malocclusions. Retraction of the canines can be achieved either individually or along with incisor. Pentraxin-3 (PTX-3) is regarded as the true independent indicator of disease activity. Hence, we undertook the present study to assess and compare the level of PTX-3 in patients ...
متن کاملSpring coil retraction in coil occlusion of persistent ductus arteriosus.
AIMS To present the short and intermediate term results of coil occlusion of persistent ductus arteriosus and the results of radiographic measurements of spring coils implanted to treat patent ducts. PATIENTS 22 children underwent coil occlusion. Their ages ranged from 2 years 9 months to 12 years 10 months (mean (SD) age, 6.5 (3.6) years). The duct diameter ranged from 1.0 to 3.5 mm at the n...
متن کاملComparison of rate of canine retraction with conventional molar anchorage and titanium implant anchorage.
INTRODUCTION Various anchorage techniques have been designed for canine retraction. Intraoral techniques have not always been successful, and now implants are widely used for this purpose. A new type of titanium microimplant, with a small diameter and a button-like head, was shown to be an effective source of anchorage for distal movement of the canines. The purposes of this study were to measu...
