The Leone Three Directional Screw is a specialized orthodontic expansion screw designed for removable orthodontic appliances. It allows controlled three-dimensional expansion of the dental arch, enabling movement in transverse and sagittal directions to create space and improve tooth alignment.

This screw is commonly used in removable plates and expansion appliances, especially in cases where simultaneous expansion and anterior movement are required.

Key Features:

• Three-directional expansion mechanism

• Allows transverse and sagittal arch expansion

• Three activation points for precise control

• Made from biomedical stainless steel for durability

• Smooth threaded components prevent unwanted reverse turning

• Designed for acrylic removable orthodontic appliances
