Orthodontic arch wire

In orthodontic treatment, orthodontic arch wire is one of the core components of fixed orthodontic appliances, which guides tooth movement by applying sustained and controllable force. The following is a detailed introduction about orthodontic wires:

1:The role of orthodontic wires Transmitting orthodontic force:

Applying force to teeth through elastic deformation to achieve goals such as alignment, leveling, and closing gaps. Maintaining dental arch shape: The arc-shaped structure that supports the arrangement of teeth, maintaining the width and length of the dental arch. Guiding 3D movement: In conjunction with bracket design, control the lip tongue, vertical, and rotational movement of teeth.

2: Classification of arch wire

2.1. Classify by material Material type characteristics, common application stages

Nickel titanium alloy wire: super elastic, shape memory effect, gentle and continuous force, suitable for initial alignment.

Stainless steel wire: high hardness and rigidity, used for precise control of tooth position.

TMA: The elastic modulus is between nickel titanium and stainless steel, and it can be bent with mild strength, suitable for mid-term adjustment.

2.2. Classify by cross-sectional shape Circular wire:

commonly 0.012-0.020 inches in diameter, initially aligned Rectangular wire: such as 0.016 × 0.022 inches, 0.021 × 0.025 inches, providing torque control.

Braided thread: Multiple strands of fine thread woven for initial gentle correction of severely misaligned teeth.

2.3. Special function dental arch wire Reverse curve wire:

pre curved, used for vertical adjustment of deep covering or opening and closing.

3:Collaboration with other orthodontic systems Traditional brackets:

rely on ligation fixation, and the matching degree between the archwire and the bracket groove needs to be considered.

Self ligating bracket: reduces ligation friction and makes it easier to slide.

The selection of orthodontic wires directly affects the treatment effect and patient experience, and requires comprehensive design based on the type of malocclusion, orthodontic stage, and bracket system.And we have all the products mentioned above that are compatible with treatment.
