Systematic review reveals clear aligners may reduce plaque and gingival inflammation versus fixed appliances, suggesting a need for standardized research.
The increasing popularity of clear aligners as an alternative to traditional fixed orthodontic appliances has prompted significant interest in their impact on periodontal health. This review examines the comparative effects of these two orthodontic modalities on key periodontal parameters, including plaque accumulation, gingival inflammation, and alveolar bone support. Evidence from various studies indicates that clear aligners offer potential advantages in reducing plaque retention and gingival inflammation due to their removability and ease of hygiene maintenance. However, differences across studies and inconsistencies in methodologies highlight the need for standardized research approaches and long-term clinical trials to confirm the sustainability of these benefits. Understanding the periodontal implications of orthodontic treatment choices is essential for clinicians to adopt a patient-centered approach that optimizes periodontal health throughout and after treatment.
