Orthodontic wire Reverse curve (NiTi Rectangular)

Description

🔧 Primary Uses of Reverse Curve NiTi Rectangular Wire:

1. Deep Bite Correction:

   • Helps in intruding anterior teeth (upper or lower) and extruding posterior teeth to flatten the curve of Spee.

   • This action helps reduce excessive overbite.

2. Open Bite Treatment:

   • Can be reversed (upside-down curve) to extrude anterior teeth and intrude posterior teeth, aiding in closure of an anterior open bite.

3. Arch Leveling:

   • Ideal for flattening the occlusal plane during early or mid-level treatment phases.

   • Especially helpful in levelling lower arches where the curve of Spee is exaggerated.

4. Torque Control:

   • Rectangular wire provides better torque control compared to round wire due to engagement with bracket slots.

5. Improved Anchorage Control:

   • The archwire’s unique shape can assist in redistributing forces, reducing the need for additional anchorage methods in certain cases.

6. Used in Combination with Elastics or Auxiliaries:

   • Often paired with class II or class III elastics or bite turbos depending on the malocclusion being treated.

🦷 Key Features of Reverse Curve NiTi Rectangular Wire:

1. 1. 1. Reverse Curve of Spee Design:

         • Pre-formed with a negative curve (opposite of natural curve of Spee) to aid in bite correction.

         • Enhances leveling of deep curves and helps adjust the vertical dimension of the arch.

      2. Shape-Memory Property (NiTi Alloy):

         • Made from Nickel-Titanium, which provides excellent shape memory and superelasticity.

         • Returns to its original form after deformation, applying continuous light forces over time.

      3. Rectangular Cross-Section:

         • Engages bracket slots more completely than round wires.

         • Offers three-dimensional control, especially for torque and rotational correction.

      4. Low Load-Deflection Rate:

         • Delivers consistent and gentle forces, minimizing patient discomfort while effectively moving teeth.

      5. Corrosion Resistance:

         • NiTi alloy is highly resistant to oral conditions, ensuring durability and performance over extended periods.

      6. Efficient Arch Leveling:

         • Designed specifically for leveling the curve of Spee, aiding in both deep bite and open bite correction.

      7. Compatible with Both Upper and Lower Arches:

         • Available in forms designed for mandibular (lower) and maxillary (upper) arches, depending on treatment goals.

🦷 Benefits of Reverse Curve NiTi Rectangular Wire:

1. Deep Bite Correction
   – Helps intrude anterior teeth and extrude posterior teeth, reducing deep overbite efficiently.

2. Open Bite Management (when inverted)
   – When used upside down, assists in extruding anterior teeth and intruding posteriors to close anterior open bites.

3. Arch Leveling and Flattening Curve of Spee
   – Promotes vertical alignment of teeth by flattening the exaggerated curve of Spee.

4. Continuous Gentle Forces
   – NiTi’s superelastic property delivers light, sustained force, which is more comfortable and biologically favorable.

5. Three-Dimensional Control
   – The rectangular wire engages the bracket slot fully, enabling better torque, rotation, and vertical control.

6. Faster Treatment Progression
   – Aids in early leveling and bite correction, which can lead to reduced overall treatment time.

7. Improved Patient Comfort
   – Light forces cause less discomfort than stiffer wires like stainless steel.

8. Corrosion Resistant and Durable
   – NiTi is highly resistant to corrosion in the oral environment, offering long-term stability.
