Orthodontic wires Natural (NiTi Rectangular)

Description

Natural NiTi Rectangular Wires — Main Uses:

• Intermediate Stage of Treatment

  • After initial alignment with round wires, rectangular NiTi wires are introduced to start more precise tooth movements.

• Torque Control

  • Helps control the root position of teeth, not just the crowns (important for getting teeth upright inside the bone).

• Rotation and Angulation Correction

  • Provides better grip and control over tooth rotation and tilting compared to round wires.

• Arch Form Maintenance

  • Maintains the designed arch shape while teeth are moved into their correct positions.

• Space Closure Support

  • Assists in moving teeth accurately during space closure mechanics (like after premolar extractions).

• Preparation for Final Stages

  • Prepares teeth for the final heavy rectangular stainless steel wires (by already aligning roots into better positions).

• Light Force Finishing (in sensitive cases)

  • In cases where lighter forces are preferred even in finishing, rectangular NiTi wires can be used instead of stiffer steel.

Natural NiTi Rectangular Wires — Benefits:

• Excellent 3D Tooth Control

  • Controls rotation, tipping, angulation, and root torque much better than round wires.

• Light and Continuous Forces

  • Provides gentle, consistent pressure, reducing patient discomfort while still moving teeth effectively.

• Maintains Arch Form

  • Thanks to the shape-memory effect, the wire keeps the desired arch shape even when under stress from misaligned teeth.

• Smooth Transition in Treatment

  • Perfect for the middle to finishing stages — helps move from basic alignment (round wires) to precise finishing (stainless steel wires).

• Reduced Treatment Time

  • Efficient force application can shorten the time needed for tooth movement compared to non-superelastic materials.

• Patient Comfort

  • More comfortable than rigid stainless steel rectangular wires, especially when first moving into rectangular stages.

• Durable and Resilient

  • Resistant to permanent deformation — even after bending, it returns to its original shape.

• No Coating Peeling

  • Being a natural (uncoated) wire, there’s no risk of white/esthetic coatings peeling off during treatment.

Natural NiTi Rectangular Wire — Features:

• Material:

  • Nickel-Titanium (NiTi)

  • Superelastic and shape-memory properties

• Surface:

  • Natural finish (non-coated, metallic silver-gray color)

  • Smooth polished surface to reduce friction and improve sliding

• Shape:

  • Rectangular cross-section (e.g., 0.016″ × 0.022″, 0.017″ × 0.025″, 0.018″ × 0.025″, 0.019″ × 0.025″)

  • Provides excellent engagement in bracket slots

• Flexibility:

  • More rigid than round wires but still flexible compared to stainless steel wires

  • Ideal for intermediate to finishing stages of treatment

• Force Delivery:

  • Delivers consistent light continuous forces

  • Helps in 3D tooth control (tipping, rotation, torque, and root positioning)

• Temperature Sensitivity (for some types):

  • Some natural NiTi wires are thermo-activated, responding to body temperature to activate gentle forces
