Compression, or Open Coil, springs are used to create spaces between teeth or, more simply, to move points away from one another. The coils are compressed when loaded and provide forces ‘outward’ to create and maintain needed space.
NiTi compression springs are available in both Variable and Superelastic forces.
Compression, or Open Coil, springs are used to create space between teeth. Compressed during placement, the spring then exerts continuous force against the teeth as they return to original length.
The tooth-moving force of variable force springs gradually decreases over the activation range. The tooth-moving force of superelastic force springs remains near constant over the activation range. To accommodate your doctor’s preferences, we offer a wide variety of variable and superelastic springs with force levels from light to heavy.
Made of premium Nickel Titanium wire.
Provide continuous forces throughout activation.
Virtually no permanent deformation with proper usage.
Wide range of forces available.
Helpful Hint:
The greater the wire size, the higher for force.
The smaller the inside diameter (lumen), the higher the force.
The shorter the length (# of active coils), the higher the force.
An economical offering, Stainless Steel springs provide high initial forces; however, unlike the forces of our premium Nickel Titanium spring, Stainless Steel forces decrease rapidly with tooth movement. Stainless Steel springs are also subject to taking a permanent set when fully compressed or expanded.
Manufactured of 304V Stainless Steel
Spooled 40 inch springs allow for convenient chairside sizing.
Extension springs are effective in maintaining space openings.
Compression springs are most commonly used to create space.
