This systematic review and meta-analysis investigated the effects of clear aligners versus fixed appliances on established outcomes.</p><p><strong>Materials and methods: </strong>A systematic search was conducted in PubMed, Scopus, Cochrane Library, Embase, and ScienceDirect up to March 2025, along with gray literature and manual searching of key orthodontic journals. The eligible studies consisted of randomized controlled trials and observational studies that evaluated clear aligners against fixed appliances based on the plaque index (PI), gingival index (GI), probing depth (PD), pain intensity, and QOL.
