Evaluation of Effects of Clear Aligners vs Fixed Appliances on Oral Health Related Quality of Life During Orthodontic Treatment: A Prospective Study
Year: 2025
Type: article
Abstract: Background: Orthodontic treatment is often associated with discomfort, esthetic concerns, and functional limitations, all of which can impact oral health-related quality of life (OHRQoL). Clear aligners have emerged as a more esthetic and comfortable alternative to traditional fixed appliances. Methods: A total of 80 participants (mean age: 21.6 ± 3.4 years) undergoing orthodontic treatment were recruited and divided equally into two groups: Group A (clear aligners) and Group B (fixed appliances). OHRQoL was assessed using the Oral Health Impact Profile-14 (OHIP-14) questionnaire at baseline (T0), 3 months (T1), and 6 months (T2). Statistical analyses included paired and unpaired t-tests and repeated-measures ANOVA. Results: Both groups showed an initial decline in OHRQoL after appliance placement. However, Group A demonstrated significantly better scores in physical pain (T1: 3.1 ± 1.0 vs 5.4 ± 1.3, P < 0.001), psychological discomfort (T2: 2.6 ± 0.9 vs 4.8 ± 1.5, P = 0.002), and social disability (T2: 1.9 ± 0.6 vs 3.5 ± 1.1, P = 0.004) compared to Group B. By 6 months, the aligner group showed significant recovery in OHRQoL domains, whereas fixed appliance users continued to experience moderate impact. Conclusion: Clear aligners are associated with a more favorable OHRQoL during orthodontic treatment compared to fixed appliances, particularly in reducing pain, psychological stress, and social challenges.
