An orthodontic palate expander screw is a fixed, bonded device used to gradually widen the upper jaw (maxillary arch) in children or adolescents. Clinically, it helps correct narrow palates, improve tooth alignment, and address skeletal discrepancies by applying gentle, controlled expansion over time under orthodontic supervision.
These devices are typically single-use, designed for one patient throughout their treatment period, and are adjusted periodically by a dentist or orthodontist. Regulation varies by jurisdiction, but they are generally classified as medical devices due to their direct contact with oral tissues and functional role in orthodontic therapy.
