Expansion Screws

Perfect in form 

the skeletal construction enables the screws to have the smallest possible dimensions, yet achieve the largest possible expansion. The integrated expansion stop prevents the screws from falling apart.

Perfect in function 

the friction on the thread of the screws is so exact that they are guaranteed to open evenly. The unique click versions are secured against unwanted reversing, thereby preventing the screws used for the fixed appliance technique from turning back.

Perfect in design 

the high-precision screws have a stable construction and are of high quality. They can be fixed securely in the acrylic.

• Stainless steel
• With cone-shaped expansion screw holder
• skeleton design
• holes in body of screws for better retention in acrylic
• built-in stops prevent screws from coming apart
• With expansion screw key straight, small – standard.
