Orthodontic palate expander screw, self-removable

Orthodontic palate expander screws are removable devices used in dental treatments to gradually widen the upper jaw (maxillary arch). They help create space for proper tooth alignment by applying gentle pressure, often during childhood or adolescence when the jaw is still growing.

These devices are typically reusable and designed for patient self-removal during meals or oral hygiene. Regulation varies by jurisdiction, but they are generally classified based on their intended use and risk profile, with compliance requirements covering safety, materials, and performance standards.
