The ecological impact of resin-printed models in clear aligner treatment

Abstract

Clear aligner therapy has gained immense popularity among orthodontists and general dentists as a treatment option for orthodontic tooth movement. This rapidly growing technology has successfully treated 14 million patients, resulting in an estimated production of 728 million plastic models and aligners. However, the disposal of these models and aligners presents a significant environmental concern because they are either destined for landfill, where they can leach harmful substances into the environment, or incinerated, leading to the release of carcinogenic toxins. This article explores the environmental impact of clear aligner technology, shedding light on the potential consequences associated with its widespread adoption. CPD/Clinical Relevance: To introduce the topic of the environmental impact of clear aligner therapy and the possible solutions to tackle this issue from a clinical and industry-based standpoint.
