What this trial studies

This clinical trial evaluates the effectiveness of a modified 3D printed customized maxillary protraction facemask compared to a conventional facemask in treating Class III malocclusion in young patients. It is a multicenter randomized trial where participants are divided into two groups, one receiving the modified facemask and the other the conventional appliance. The study will assess treatment outcomes using lateral cephalometric x-rays, study models, photographs, and patient questionnaires before and after treatment. The goal is to determine which appliance provides better correction of jaw protrusions.

Who should consider this trial

Good fit: Ideal candidates are young patients with skeletal Class III malocclusion characterized by a retrognathic maxilla and normal mandible.

Not a fit: Patients with previous orthodontic treatment, significant facial asymmetry, or certain dental health issues may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to more effective treatment options for young patients with Class III malocclusion.

How similar studies have performed: While the use of facemasks in orthodontics is established, the specific application of a modified 3D printed facemask is a novel approach that has not been extensively tested.
