Towards Sustainable Orthodontics: Environmental Implications and Strategies for Clear Aligner Therapy
Summary
This review examines the environmental footprint of clear dental aligners, which are made from plastic polymers and generate significant waste since patients use multiple sets over treatment. The manufacturing and disposal of aligners contributes to microplastic pollution, and the paper suggests the dental industry should adopt more sustainable materials and recycling programs to reduce this impact.
The increasing concern over environmental sustainability has prompted various industries to reassess their practices and explore greener alternatives. Dentistry, as a significant contributor to waste generation, is actively seeking methods to minimize its environmental footprint. This paper examines the environmental implications of clear aligner therapy (CAT) in orthodontics and explores strategies to prioritize sustainability in aligner manufacturing and usage. CAT has gained popularity as a viable alternative to traditional fixed appliances due to advancements in biomaterials and computer-aided design (CAD) and manufacturing (CAM) technologies. The global market for clear aligners is expanding rapidly, with significant growth projected in the coming years. To address these challenges, this paper proposes adopting the principles of reduce, reuse, recycle, and rethink (4Rs) in orthodontic practices. Strategies such as minimizing resource consumption, incorporating recycled materials, and promoting proper aligner disposal and recycling can significantly reduce environmental harm. This paper explores emerging technologies and materials to mitigate the environmental impacts of CAT. Additionally, initiatives promoting aligner recycling and repurposing offer promising avenues for reducing plastic waste and fostering a circular economy. In conclusion, while CAT offers numerous benefits in orthodontic treatment, its environmental impact cannot be overlooked. By implementing sustainable practices and embracing innovative solutions, the orthodontic community can contribute to a more environmentally conscious future while continuing to provide quality care to patients.

A scoping review of sustainable orthodontic supply chains: innovations and waste management in clear aligner therapy.
A scoping review found that clear aligner orthodontic therapy generates over 1,000 tons of plastic waste annually and produces microplastic contamination, raising significant sustainability concerns. Despite digital advances, the orthodontic supply chain has been slow to adopt effective waste reduction strategies.
Can Clear Aligners Release Microplastics That Impact the Patient’s Overall Health? A Systematic Review
This systematic review investigates whether clear orthodontic aligners release microplastics during use in the mouth. The findings raise concerns about a previously overlooked source of direct microplastic exposure, since millions of people wear these plastic devices against their teeth and gums for months or years at a time.
Getting your teeth fixed can be an environmental hazard
This commentary discusses the environmental hazard of discarded dental aligners, which end up in landfills and take decades to decompose, releasing microplastics in the process. The author calls for aligner manufacturers and dental practitioners to adopt take-back and recycling programs to reduce the contribution of orthodontic plastic waste to the global microplastic burden.
Experimental assessment of damage and microplastic release during cyclic loading of clear aligners
Researchers tested three popular brands of clear orthodontic aligners under simulated chewing conditions and found that all released microplastic particles during use. Since patients wear aligners for extended periods each day, this represents a direct and ongoing source of microplastic ingestion, raising questions about the cumulative exposure from dental devices that are growing in popularity.
Microplastics in Orthodontics
This paper reviews how microplastics can leach from dental and orthodontic materials such as toothpaste, retainers, aligners, and adhesives, with the oral cavity being a direct route for microplastic ingestion. As orthodontic treatments become more common, especially clear aligner therapy, understanding the extent of microplastic release from these devices is important for assessing patient exposure.
