Anterior Openbite Clinical Trial
— SPaTAROfficial title:
Single Palatal Temporary Anchorage Device for Anterior Open Bite: a Randomized Clinical Trial
Participants are orthodontic patients with anterior open bite (AOB) malocclusion. These patients will be treated by molar intrusion achieved using one of two interventions, either orthodontic fixed appliances incorporating a single palatal Temporary Anchorage Device (TAD) or orthodontic fixed appliances incorporating two buccal TADs

Type | Measure | Description | Time frame | Safety issue |
---|---|---|---|---|
Primary | Molar intrusion | Amount of upper molar intrusion measured in mms on cephalometric radiograph | 9-12 months after treatment commences | |
Secondary | Overbite (vertical overlap of anterior teeth) | Change in overbite (vertical overlap of anterior teeth) measured clinically directly from the teeth with a ruler and on 3D dental scans using 3D analysis software, both in mms | 9-12 months after treatment commences | |
Secondary | Patient Experience | Patient experience with the use of temporary anchorage devices for intrusion by validated questionnaire which uses 3 or 4 point Likert Scales for a range of questions across relevant doamins. Depending on the question the scales are 'Improved/Same/Worse/Much worse' or 'Not at all / A little / A lot' or 'I do more / no difference / I do less' (Yassir et al 2017) | 9-12 months after treatment commences |
