• Research summary

  This research project aims to determine predictive factors for the success of Twin-Block functional appliance treatment. Twin-block appliances have been in use in orthodontics the UK for many years. Whilst there is an abundance of evidence on the positive effects of Twin-Blocks in Class II malocclusions, there is wide range of treatment successes reported. Some patients respond very favourably whilst others achieve minimal effects. This study aims to identify any clinical and radiographic characteristics that may predispose to a more favourable treatment outcome. This has the potential to streamline resources and services to those who may benefit most along with adding valuable information to the literature surrounding this topic.
  This is a prospective observational cohort study. This study would involve participants between the ages of 10-16 years of age already planned for a Twin-Block appliance treatment in the orthodontic units in Manchester University Foundation Trust. There will be no funding for this study. Participants will be asked to join the study once deemed suitable and planned to receive a Twin-Block appliance. Participants will only be involved in this study for data collection purposes only. They will undergo this treatment as normal. Data (clinical and radiographic) will be collected by their clinician and research team using a standardised form at their initial appointment and at 6 months into treatment. There will be no change to the usual standard of care provided for patients receiving this appliance. The study will last for 6 months from initiation of treatment for each participant.
