Power Chains

1. Efficiently close gaps

Continuous light force: Rubber chains can provide sustained and gentle force, suitable for slowly moving teeth, to avoid sudden force causing root resorption or pain.

Multi tooth synchronous movement: can simultaneously act on multiple teeth (such as closing gaps after tooth extraction), improving treatment efficiency.

2. Accurately control the position of teeth

Direction controllable: By adjusting the traction direction of the rubber chain (horizontal, vertical, or diagonal), the movement path of the teeth can be precisely controlled.

Segmented use: can be applied locally to specific teeth (such as adjusting the midline of the front teeth) to avoid affecting other teeth.

3. Elastic advantage

Flexibility and adaptability: Elastic materials can adapt to changes in the position of teeth during movement, reducing the rigid impact on teeth.

Gradual force application: As the teeth move, the rubber chain gradually releases the force value, which is more in line with physiological movement needs.

4. Easy to operate

Easy to install: can be directly hung on brackets or orthodontic archwires, with short chair side operation time.

Color selection: Available in multiple colors (transparent, colored), while also considering aesthetics (especially the transparent version is suitable for adult patients).

5. Economical and practical

Low cost: Compared to other orthodontic accessories such as springs or implant braces, rubber chains are inexpensive and easy to replace.

6. Multi functional applications

Gap maintenance: prevent tooth displacement (such as when not repaired in a timely manner after tooth extraction).

Auxiliary fixation: Cooperate with archwire to stabilize the shape of the dental arch.

Bite adjustment: assist in correcting minor bite problems (such as opening and closing, deep coverage).
