Orthodontic retention: what's on the horizon?

Orthodontic retention remains one of the great challenges in orthodontics. In this article, we discuss what is on the horizon to help address this challenge, including biological approaches to reduce relapse, treating patients without using retainers, technological developments, personalised medicine and the impact of COVID-19 on approaches to orthodontic retention. Key points As our understanding of biological factors affecting relapse improves, we may be able to harness this knowledge to improve stability after orthodontic treatment. Developments in new retainer materials, digital workflow and monitoring using artificial intelligence are being investigated in the field of orthodontic retention. Personalised medicine and patient-centred care is likely to change our approach to reducing orthodontic relapse in the future.
