Development of 'My Retainers' mobile application: Triangulation of two qualitative methods.

Objective: Diligent wear of removable orthodontic retainers requires prolonged adherence and is invariably necessary to preserve optimal results. Patient-informed behaviour-change interventions represent a promising and novel means of enhancing adherence to removable retainer wear. The aim of this study was to describe the development of a patient-informed mobile application designed to enhance retainer wear.

Factors influencing adherence to vacuum-formed retainer wear: A qualitative study.

Objective: To explore factors influencing adherence to vacuum-formed retainer wear over a minimum period of four years.

Design: A qualitative study based on a randomised controlled trial assessing the effectiveness of orthodontic retainers.

Setting: Institute of Dentistry, Queen Mary University of London.
