fiber reinforced composite arch-wires in orthodontics: function meets esthetics. orthodontic tooth movement is carried out, by engaging successively increasing sizes of archwires in brackets, which are bonded to the teeth. traditionally, brackets as well as archwires were manufactured with stainless steel or chrome-cobalt alloy.
fiber-reinforced composite archwires offer aesthetics and clinical flexibility a variety of archwires are available to the clinician, and it can be difficult to decide which archwire has the desired properties for a given clinical situation. 1 4 often, there may be several wires to choose from, each offering similar characteristics.

orthodontic treatment has undergone a drastic transformation for a few years. many patients present with a set of challenges to orthodontists in terms of esthetics while undergoing orthodontic treatment. the introduction of composite and ceramic brackets has led to the development of esthetic archwires to meet the increased demand for esthetics during orthodontic treatment.
fiber-reinforced polymer composites are currently being developed for use as orthodontic archwire materials. by adjusting the ceramic/polymer proportions, these wires can be manufactured in a wide range of clinically relevant levels of elastic stiffness, allowing practitioners to use variable-modulus orthodontic techniques without having to change arch wire materials as treatment progresses.
spendlove et al. showed that although fiber-reinforced composite presented a similar bending profile and larger dimension, it delivered lower force than conventional niti, because it was not so stiff and resulting delivered less force. the experiment, the duration of which was 30 days at a temperature of 37 c, with a 2-mm observed deflection, caused crazing and a decrease in force delivery, which was confirmed by statistical analyses of the results.
fiber-reinforced polymer composite frpc archwires could provide an esthetic solution to conventional orthodontic archwires. this study was carried out with the following aims: 1 to compare the sliding friction of frpc archwire with nickel titanium archwire using various archwire-bracket combinations and 2 to determine the correlation between surface roughness and friction of the frpc and niti archwires.
transparency of both glass fibers and polymeric resin. differently from metals, fiber reinforced composites can be primarily designed as a material and tailored for specific applications. however, the viscoelastic behavior of gfrp under creep should be evaluated more carefully in order to support this application.

fiber reinforced composite archwire fiber reinforced composite arch wires are fabricated using a procedure called pultrusion. fiber bundles are pulled through an extruder, in which they are wetted with a monomer resin. then the monomer is cured with heat and pressure resulting in manufactured by glenroe technologies polymerization.
for fibre-reinforced composite archwires to be considered as a viable treatment alternative for niti archwires, they must not experience large amounts of stress relaxation and they must be able to undergo large deflections without permanently deforming or crazing.
glass fibres are used to reinforce composite in a number of clinical applications, in orthodontics as well as in general dentistry. in this paper, a transpalatal arch made of fibre reinforced composite is described as an anchorage device bonded to molars and premolars to orthodontically reposition an impacted maxillary canine by means of a palatal cantilever in a highly demanding patient from
a fiber-reinforced composite frc is a composite building material that consists of three components: the fibers as the discontinuous or dispersed phase, the matrix as the continuous phase, and; the fine interphase region, also known as the interface.
for each bracket, the resistance to sliding was measured at four bracket angulations 0 , 2.5 , 5 , and 10 in a dry state at room temperature. the fiber reinforced composite archwire produced the lowest sliding resistance with the passive self-ligating bracket system damon dq at each bracket angulation tested.
the purpose of this study was to analyze the resistance to sliding of coated rectangular fiber reinforced composite archwires using various brackets systems and second-order bracket angulations. resistance to sliding was investigated for eight bracket systems: six self-ligating brackets four passive and two passive-active and two conventional
the mechanical properties of continuous fiber reinforced polymers are quite a bit higher in the longitudinal directions than in other directions. the failure processes of the composite are fiber/matrix debonding, fiber pull out, fiber fracture, crazing and fracture of the matrix.
