Nickel Titanium’s superelastic qualities make it the perfect material for orthodontic springs. With proper usage, NiTi springs are highly resistant to permanent set and provide comfortable, predictable forces during treatment. In comparison, stainless steel springs exert high initial forces, lose force quickly after placement, and will commonly take a permanent set. Adenta is pleased to offer our Nickel Titanium compression and extension springs in Variable and Superelastic forces to meet the needs of specific treatment plans.

Variable Force springs are our most popular spring. They are designed so that the  activation force gradually increases with greater activation, and subsequently, the tooth-moving force gradually decreases as the spring returns to its nominal length. Representative Variable Force Spring 3-Point Bend Test results are indicated in black on the graphs on the preceding page. In the case of Compression springs, the activation force increases as it is compressed, and the tooth-moving force gradually decreases as the spring returns.  Likewise, in the case of Extension springs, the activation force increases as it is extended, and the tooth-moving force gradually decreases as the spring returns.

Superelastic Force springs provide a near constant tooth-moving force throughout their activation range. Both Extension and Compression Superelastic Force springs exhibit this same characteristic; the force remains near constant throughout their applied range. Many doctors find the constant force to be advantageous when loading springs in TAD (Temporary Anchorage Device) treatment.

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.

NiTi compression springs are available in both Variable and Superelastic forces.

As explained above, 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 doctors’ 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.

Compression Springs 7 inch lengths (3 per tube) and 15 inch spools.

Helpful Hint:
• The greater the wire size, the higher the force.
• The smaller the inside diameter (lumen), the higher the force.
• The shorter the length (# of active coils), the higher the force.

Extension, or Closed Coil, springs are used to maintain or close spaces. Adenta offers extension springs in popular lengths with pre-attached Key-end™ eyelets. Our Key-ends are attached firmly to the spring and are manufactured with smooth edges and round hole for easy attachment to TADs (Temporary Anchorage Devices), hooks, or brackets to retract teeth.

Adenta offers Nickel Titanium Extension Springs in both Variable and Superelastic forces. Variable Extension Springs, our most popular, provide gentle tooth-moving forces that gradually decrease during retraction. Superelastic Extension Springs provide near constant tooth-moving forces throughout their activation range.

• Springs are made of premium Nickel Titanium wire.

• Provide continuous retraction forces throughout activation.

• Securely attached, precision designed Stainless Steel Key-end eyelets for easy attachment.

• Virtually no permanent deformation with proper use.

• Recommended activation length is two times original spring length.

Extension Springs 6mm, 9mm, 12mm, 15mm lengths (all with Key-ends)

Class II springs have a greater activation range than Stainless Steel springs, and do not require patient compliance as needed with Class II elastics.

• Easy ligation for Class II correction.

• Nickel Titanium 15mm Variable force extension spring.

• Secure Stainless Steel eyelets and ligature wire.
