Modern orthodontics has reached a new milestone with the introduction of nickel-titanium TAD closed coil springs, a breakthrough technology offering unprecedented precision in tooth movement control. These innovative devices combine advanced materials science with thoughtful engineering to address longstanding clinical challenges.

The spring's closed coil configuration delivers continuous, uniform force transmission—a significant improvement over traditional open coil designs. This structure eliminates common issues like hook friction and patient discomfort while providing predictable force application throughout treatment phases.

Medical-grade stainless steel connection points ensure exceptional biocompatibility and durability. These eyelets facilitate secure attachment to various orthodontic components including brackets, archwires, and temporary anchorage devices (TADs), streamlining clinical procedures.

The NiTi alloy's superelasticity and shape memory characteristics enable:

• Constant force delivery across wide activation ranges
• Minimal force decay during extended use
• Physiologically appropriate light forces for tissue-friendly movement
• Reduced adjustment frequency compared to stainless steel alternatives

Optimal performance requires understanding key parameters:

• Wire diameter: Standard .010" (0.254mm) provides gentle forces for precise micro-adjustments
• Coil diameter: .030" (0.762mm) internal dimension balances force characteristics with working range
• Length options: Available in 7mm, 9mm, 12mm, and 15mm configurations to accommodate various movement requirements

When combined with TADs, these springs enable controlled movements including:

• Mesial/distal tooth translation
• Space closure management
• Vertical positioning (intrusion/extrusion)

The system reduces chair time through:

• Fewer reactivation appointments
• Simplified attachment procedures
• Predictable treatment progression

Consistent light forces minimize discomfort, improving treatment compliance compared to conventional spring systems.

The orthodontic system includes complementary components:

• Oval eyelet TAD closed coil variants
• RM® Lock hooks for complex force systems
• Arch markers for precise treatment planning
• Alpine SL twin stainless steel brackets
• Wire management accessories

This integrated approach provides clinicians with complete solutions for diverse treatment scenarios, from routine cases to complex malocclusions requiring sophisticated biomechanical control.
