Brief Summary
evaluate and compare the efficiency between elastomeric chains and burston T-loop retractors in terms of rate of maxillary canine retraction and canine movements
Detailed Description
The purpose of orthodontic treatment is to move teeth as efficiently as possible with minimal adverse effects on teeth and supporting tissue. Numerous methods of canine retraction are currently in common use. Force can be applied through the elastics, closed coil springs, wire loops of numerous designs, and a number of headgear types currently available. The principles for retraction currently used in preadjusted edgewise mechanics can be described as either:(a) a frictional system in which the canine is expected to slide distally along a continuous archwire, (b) frictionless mechanics in which loops (springs) are incorporated in a continuous or a segmental archwire to retract teeth. The sliding mechanism in any application other than simple tipping movement has two disadvantages: (i) friction (ii)force magnitudes cannot be easily determined since the amount of friction is relatively unknown and unpredictable.1 Space closure in orthodontics is the second stage incomprehensive fixed appliance treatment and can be accomplished by either sliding mechanics or loop mechanics. Nickel-titanium closed-coil springs and elastomeric power chains (PC) are the most common force delivery systems used in space closure In vitro studies of the properties of PC showed that they lose force much more rapidly than springs over time.2-3In addition, environmental factors and temperature have greater effects on the properties of PC than on CS.4 Arch-length-to-tooth-mass discrepancy patients require extraction of teeth and closure of those spaces to correct their malocclusion. There are different mechanical methods used in orthodontic practice to move teeth, such as using various types of elastic materials and coil springs5During the past few years, elastomeric power chains (EPCs) have been used in preference to other retraction orthodontic materials because of their elastic properties, ease of application and requiring no patient co-operation, low cost, being relatively hygienic, and their irritation-free nature due to their smooth surface6 The proper position of canines shares a very important role in oral function and esthetics. Their unique position makes their orthodontic movement of great clinical importance, especially in premolar extraction cases. Segmented arch technique is a modified edgewise orthodontic procedure developed by Burstone7 in 1962 which consists of multiple wires found in different portions of arch. The force systems are relatively constant and with long ranges of activation and optimum force levels their resulting movement is predictable, as stated by Burstone, Baldwin, Lawless.8 Later in 1966, Burstone CJ9 stated that moment-to-force ratio, magnitude of force and the constancy of force determine the success of an appliance. The segmented arch technique has many advantages like better control over the forces, more efficient tooth movement over long distances with light constant forces, as stated by Burstone, Koenig (1976).10 In 1980, Burstone and Goldberg11 introduced beta titanium molybdenum alloy (TMA) wire (11%molybdenum, 6% zirconium and 6% beta titanium alloy) which showed twice the amount of deflection and delivered half the amount of force as compared to stainless steel wires. Burstone, van Steenbergen, Hanley12 in 1995 mentioned that T-loops had three important characteristics, i.e."α" , i.e. anterior moment or β, i.e. posterior moment and a horizontal moment. Viecilli (2006)13 stated that the effects of steps, angles and vertical forces could be combined to produce an ideal T-loop design. According to Proffit (2007),14 segmented retraction of canines with frictionless springs reduces the strain on posterior teeth. The T-loop design generally provides a constant moment:force (M:F) ratio, a light and constant force throughout the entire activation range of a closing loop, and a constant low load-deflection rate15 Canine retraction and space closure is considered the most time-consuming phase in orthodontic treatment.16 Acceleration of this step would reduce overall treatment time, improve patient cooperation, and decrease possible negative side effects.17,18 Manipulation of tooth biomechanics16-19and tissue reaction20 have been widely attempted to reduce treatment duration. Additionally, the rate and safety of different canine retraction methods20 and different force Various techniques for canine retraction have been introduced including Nickel Titanium closing coil, Elastomeric chains, and lace backs. On the other hand, frictionless mechanics imply the use of the sectional method as the use of Burstone's T - loop, Rickett's spring, or Gjessing's spring Researchers were interested in investigating the effect of different force levels on the rate of canine retraction using sectional springs. And many authors have described various designs of canine retraction springs, their suitability and efficiency 21,22
