Microplastic exposure from clear aligners has been a topic of discussion within the specialty recently, with an article in the Journal of the World Federation of Orthodontists and a post on Kevin O’Brien’s Orthodontic Blog addressing the topic.
The American Association of Orthodontists (AAO) currently does not hold a formal position on the issue of microplastics in clear aligners. Although some preliminary research has explored potential connections between microplastics in these devices and health impacts, the existing body of evidence is not sufficient to draw definitive conclusions at this time. The AAO, recognizing that this is an emerging and important issue, remains committed to promoting and protecting patient health and safety.
To that end, the AAO is dedicated to monitoring developments, supporting further investigation, and working toward a clearer understanding of any potential implications. The AAO has convened a team of researchers to carefully review all available studies on this matter. Furthermore, the AAO Board of Trustees has asked the AAO Foundation’s Planning and Awards Review Committee (PARC) to issue a call for additional research proposals, with the possibility of funding new projects. The AAO will continue to follow this issue closely.
The AAO acknowledges the efforts that manufacturers of orthodontic products have made in developing innovative and effective treatment options. At the same time, the AAO encourages the ongoing advancement of such products to ensure that patient well-being remains central to orthodontic care while striving for optimal treatment outcomes.
Separately from questions within the orthodontic specialty, in recent years medical, scientific and journalistic reports have discussed how tiny particles of plastic have become ubiquitous on our planet, including in the food supply, due to the widespread use of plastic products.
The journal Nature Medicine explains how human exposure may commonly occur via the food supply but also through ingestion from plastic containers in which liquid has been stored or heated, such as water bottles or feeding bottles for infants. Plastic particles may also be inhaled.
Carcinogens and endocrine disruptors are among the chemicals in plastics, with current research raising concerns about exposure to plastic particles within human tissues and its impact on human health.
