The goal of this split-mouth, head-to-head, randomized controlled trial is to compare the effects of a fixed straight retainer with the V- loop bonded retainer on periodontal health in patients with the requirement of continuous fixed retention for 12-24 months after orthodontic treatment. The main question it aims to answer is whether the V- loop bonded retainer is more effective than fixed straight retainer for periodontal health management. Each patient will receive 2 lower fixed and bonded retainers: (1) a straight wire retainer (SWR) and (2) a looped wire retainer (LWR). Patients will be asked to floss once daily with a thread flosser. Researchers will compare the effects of two types of retainers to see if there is a statistically significant difference.
