Orthodontic hyrex expansion screw for effective and reliable extension of the palatine suture using non–removable structures and expanding RPE devices. With reverse unwinding protection. It is ideal for manufacturing expansion devices in 3D format.
The main advantages:
•Optimal locking of the screw during the active phase of treatment
• Built-in stopper prevents the screw from breaking after maximum expansion has been achieved
• Does not contain solder
• Precise activation/deactivation of the screw with a clearly audible “click” sound after ¼ turn
• Protective mechanism against reverse unwinding
• Minimum dimensions, maximum expansion
