研究问题
However, narrative discussions frequently combine direct environmental measurements with indirect clinical, microbiological, or material outcomes.
方法
The search strategy was revised for reproducibility and consistency with the PICOS criteria.
核心结论
Forty reports were excluded because they were reviews or commentaries, lacked a direct sustainability outcome, were not orthodontic in scope, or used an ineligible design.；The marked reduction from 680 records to five included studies reflects the deliberate exclusion of reviews/commentaries, non-orthodontic studies, and studies that discussed sustainability without directly measuring an environmental outcome or explicit sustainability-related implementation behavior ().；The revised synthesis deliberately excludes studies reporting only antimicrobial, microbiological, salivary, metal-release, or general dental outcomes because these do not directly establish environmental sustainability in orthodontics. ‖ 结论：These conclusions apply to the selected direct or explicitly sustainability-oriented evidence and should not be generalized to all orthodontic technologies, materials, or healthcare settings.
局限
Accordingly, the review should be interpreted as a synthesis of highly selected direct or explicitly sustainability-oriented evidence, not as a comprehensive map of every orthodontic publication that mentions sustainability.；Therefore, even apparently similar appliance comparisons performed in different settings may not be directly comparable, and an environmentally preferable result in one modeled scenario should not be treated as a universal property of the appliance.；Because these studies are cross-sectional and self-reported, the identified barriers should be interpreted as perceived constraints or correlates of reported practice rather than as demonstrated causes of environmental outcom
