Summary

Following completion of orthodontic treatment, prolonged retention with either part-time or full-time wear of retainers is crucial in preventing relapse. Clear thermoformed retainers (TFR) are easy to fabricate and popular among orthodontic patients. With the advent of digital orthodontics and the development of biocompatible photopolymerizable resin, it is now possible to fabricate direct 3D-printed retainers.

The aim of this study is to determine and compare the post-treatment stability of dentition, changes in thickness and mechanical properties of the retainers, and oral health-related quality of life (OHRQoL) of patients wearing direct 3D-printed retainers and conventional thermoformed retainers over a retention period of 6 months.
