Brief Summary

Fixed orthodontic appliances in combination with intraoral elastics are a common and effective method use in the orthodontic correction of malocclusions. However, their success is largely dependent on the patient's compliance. Failure to wear the elastics as instructed will reduce efficacy of treatment, ultimately increasing treatment time and potentially producing imperfect alignment of teeth. The hypothesis tested is that daily electronic reminders via a mobile application can significantly increase patient compliance, thus effectively improving treatment outcomes.

Outcome Measures

Primary Outcomes (1)

  • Change in number of elastics used and collected by the participant

    Participants from both arms will collect their used elastics in a plastic bag provided, which will be collected at each recall appointment and counted.

    6 weeks, 12 weeks

Secondary Outcomes (3)

  • Patient's self-reported duration of time spent wearing intraoral elastics

    6 weeks and 12 weeks

  • Change in participant's jaw relationship, measured on mm scale by difference in overbite, overjet and molar relationship

    Baseline, 6 weeks, and 12 weeks

  • Clinician-perceived level of compliance of the participant at each appointment, using discrete qualitative scale

    Baseline, 6 weeks, and 12 weeks

Study Arms (2)

Study group

EXPERIMENTAL

This group will receive 4 daily electronic reminders via the Calendar app on their mobile phones, reminding them to wear their elastics.

Behavioral: Reminders

Control group

NO INTERVENTION

This group will receive their orthodontic treatment and elastics instructions as normal, without reminders.

Interventions

RemindersBEHAVIORAL

Four reminders will be set on the patient's mobile phone's Calendar-type app, saying "Don't forget to wear your elastics", at 08:00, 13:00, 17:00 and 22:00.
