-Nickel Titanium Springs.
American Orthodontics offers the latest in nickel titanium spring technology with its open and close wound “adjustable force” titanium springs. They offer the same shape memory benefits of superelastic springs, with the added benefit of reduced inventories. With only two arbor sizes necessary, you can apply the precise force required for every situation. As these springs are extended (close wound) or compressed (open wound), forces are gradually increased, allowing a specific force to be generated at a given amount of extension or compression.
-Stainless Steel Springs.
American Orthodontics also offers stainless steel springs both spooled and straight in closed coil and open coil options.
