Description
The Leone Fan-Type Screw is a specialised orthodontic expansion screw designed to provide controlled expansion of the anterior region of the upper dental arch. Its unique fan-shaped opening mechanism allows the front portion of the palate to expand while minimising unwanted expansion in the posterior region.
Manufactured from high-quality biomedical stainless steel, the screw offers precise activation, stability and reliable performance. It is designed for incorporation into removable orthodontic appliances and is particularly useful in cases requiring anterior arch expansion.
