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 composite arch-wires in orthodontics

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.

transparent orthodontic archwires: a systematic literature

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.
