This subcategory features specialized nickel-titanium archwires with reverse curvature - NiTi reverse curve archwires, designed not only for tooth alignment but primarily for bite correction. These are not standard NiTi wires, but a targeted tool for controlled deep bite correction and Curve of Spee leveling. Here you can select NiTi reverse curve arch wires for braces that match your clinical protocols and vertical bite correction strategies.

What are NiTi reverse curve archwires and how are they different from standard NiTi wires?

Reverse curve NiTi archwires are nickel-titanium wires with a built-in reverse curve (Reverse Curve of Spee). Unlike standard archwires, they are preformed to generate a strong vertical force component when engaged in the bracket system.

Reverse Curve of Spee NiTi archwires work not only in the horizontal plane (alignment and crowding relief), but also vertically: they help intrude some teeth and extrude others, depending on the technique used. Thanks to the NiTi material, these preformed NiTi reverse curve archwires deliver long-lasting, gentle forces and a more forgiving biomechanics compared with rigid stainless steel wires that require manual bending.

Clinical indications: deep bite and Curve of Spee

NiTi reverse curve archwires are indicated when simple alignment is not enough and bite correction becomes a primary goal.

NiTi reverse curve archwires for deep bite correction

The main indication is deep bite. NiTi reverse curve archwires for deep bite correction allow you to address deep bite / deep overbite with a combination of incisor intrusion and load redistribution to posterior segments, depending on your chosen mechanics.

Because of their NiTi composition, NiTi reverse curve archwires for deep overbite deliver long-term but relatively light forces, making vertical correction more comfortable for the patient and gentler on the periodontium compared with using only rigid stainless steel wires.

Curve of Spee leveling on the lower arch

The second key indication is a pronounced Curve of Spee on the lower arch. NiTi reverse curve archwires for Curve of Spee leveling help gradually flatten the curve and prepare the patient for working and finishing stages with TMA or stainless steel archwires.

In most cases, these wires are used on the lower arch, so in clinical practice you’ll often see NiTi reverse curve archwires for lower arch described as a standard tool for correcting Curve of Spee and deep bite.

Biomechanical features of NiTi reverse curve archwires

The combination of NiTi material and reverse curvature produces a pronounced vertical effect while preserving the benefits of nickel-titanium - superelasticity and shape memory.

Orthodontic NiTi reverse curve archwires are best introduced after initial alignment with conventional NiTi archwires, once both arches are partially aligned and vertical correction can be activated safely. This sequence reduces the risk of uncontrolled vertical movements in cases with significant crowding.

Superelastic and preformed NiTi reverse curve archwires

Superelastic NiTi reverse curve archwires provide an almost constant force level across a wide activation range. This is especially important for longer intervals between visits and for deep bite cases where sudden overloads are undesirable.

Because they are preformed NiTi reverse curve archwires, the clinician does not need to spend time creating complex bends manually: you get a factory-designed profile engineered specifically for deep bite and Curve of Spee correction and can focus on overall case biomechanics.

Round and rectangular NiTi reverse curve archwires

Depending on the stage of treatment, both round NiTi reverse curve archwires and rectangular NiTi reverse curve archwires can be used.

• Round wires are typically used in earlier stages of vertical correction, where a gentle start and reduced friction are the priorities.
• Rectangular wires are indicated when you need stronger control of tooth inclination and position, combining vertical mechanics with torque and more rigid control.

Sizes and selection of NiTi reverse curve wires for your protocol

When choosing reverse curve wires, material, cross-section, and size all matter. In clinical practice, commonly used sizes include:

• 0.016 NiTi reverse curve archwire and 0.018 NiTi reverse curve archwire for relatively gentle initiation of vertical correction;
• 0.017×0.025 NiTi reverse curve archwire and 0.019×0.025 NiTi reverse curve archwire for more pronounced bite control on advanced stages.

The exact set of sizes depends on your technique, bracket system, and clinical preferences, but these options form the core of most reverse curve protocols.

How to integrate NiTi reverse curve archwires into your clinical protocol

In practice, NiTi reverse curve archwires are rarely used as the very first archwire. A more common sequence looks like this:

1. Conventional NiTi archwires for initial alignment and crowding relief;
2. Introduction of orthodontic NiTi reverse curve archwires for deep bite correction and Curve of Spee leveling;
3. Transition to TMA or stainless steel archwires for torque control and finishing.

Throughout this process, anchorage must be carefully controlled so that NiTi reverse curve archwires for Curve of Spee leveling do not cause unwanted vertical movements of non-target teeth. Attention to anchorage and activation sequence allows you to leverage the benefits of reverse curve mechanics while minimizing side effects.

FAQ: choosing and using NiTi reverse curve archwires

At which stage of treatment should I introduce NiTi reverse curve archwires?
Most clinicians introduce them after conventional NiTi archwires have addressed the main crowding and alignment issues. Once the arch form is more organized, NiTi reverse curve archwires are added to address deep bite and Curve of Spee correction.

When are reverse curve archwires especially useful, and when can I manage without them?
NiTi reverse curve archwires for deep bite correction are particularly helpful in deep bite and pronounced Curve of Spee cases, especially on the lower arch. In cases where vertical problems are minimal and the focus is on rotation and torque, you can often manage with a more traditional NiTi → TMA → stainless steel sequence.

Which sizes and cross-sections should I include in a core NiTi reverse curve set?
A minimal set typically includes one or two round sizes (for example, 0.016 or 0.018 NiTi reverse curve archwire) for a softer start and one or two rectangular sizes (for example, 0.017×0.025 or 0.019×0.025 NiTi reverse curve archwire) for enhanced bite control.

Can reverse curve archwires be used on the upper arch, or are they only for the lower?
Most often, NiTi reverse curve archwires for lower arch are used on the mandibular arch, where the Curve of Spee and deep bite are classically pronounced. However, in some techniques and specific treatment strategies, reverse curve wires may also be used on the upper arch - it depends on your orthodontic philosophy and the individual case.
