Treatment for Anterior Open Bite Using Temporary Anchorage Devices
Single Palatal Temporary Anchorage Device for Anterior Open Bite: a Randomized Clinical Trial
This study is testing two different orthodontic treatments using temporary devices to see which one helps people with an open bite get better results in correcting their teeth over 9-12 months.

What this trial studies
This clinical trial focuses on orthodontic patients suffering from anterior open bite (AOB) malocclusion. Participants will be randomly assigned to receive one of two treatment options: orthodontic fixed appliances with a single palatal Temporary Anchorage Device (TAD) or with two buccal TADs. The study aims to evaluate the effectiveness of these interventions in achieving molar intrusion and correcting the open bite over a treatment period of 9-12 months. Additional records, including cephalometric radiographs and intra-oral scans, will be collected to assess treatment outcomes and stability.
Who should consider this trial
Good fit: Ideal candidates for this study are patients aged 12 to 40 years with a mild to moderate anterior open bite of 1-6mm who are about to undergo orthodontic treatment.
Not a fit: Patients with previous upper first permanent molar extraction, craniofacial anomalies, or those with certain medical conditions affecting bone quality may not benefit from this study.
Why it matters
Potential benefit: If successful, this study could provide a more effective treatment option for patients with anterior open bite, improving their dental function and aesthetics.
How similar studies have performed: Previous studies have shown success with similar orthodontic interventions, but this specific approach using a single palatal TAD is being evaluated for its comparative effectiveness.
