The Effect of Nanoparticle Coating of Orthodontic Brackets on The Rate of Canine Retraction: A Randomized Clinical Trial

Orthodontic treatment often requires prolonged periods to achieve desired tooth movements, particularly in procedures like canine retraction. Traditional orthodontic brackets, while effective in aligning teeth, are limited by frictional resistance between the brackets and archwires, which can slow down the tooth movement process. This extended treatment time not only increases the discomfort and inconvenience for patients but also raises the risk of complications, including enamel decalcification, root resorption, and periodontal issues. Recent advancements in nanotechnology have introduced the possibility of nanoparticle coatings, which may reduce friction and improve the efficiency of tooth movement. However, there is limited clinical evidence on the effectiveness of nanoparticle-coated brackets in enhancing the rate of orthodontic tooth movement, particularly in canine retraction. Additionally, while laboratory studies suggest benefits, there is a lack of randomized clinical trials to validate these findings in real-world orthodontic settings. This study aims to address this gap by investigating the effect of nanoparticle coating on the rate of canine retraction using a randomized clinical trial design. The findings could potentially offer insights into whether nanoparticle-coated brackets present a viable option to enhance treatment efficiency and improve patient outcomes in orthodontics.
