Orthodontic Power Chain Used For Closing Extraction Spaces
Product Description
Elastics are typically made from medical-grade polymeric elastomers, such as rubber or polyurethane. Common types include ligature ties, separators, elastic chains, and O-rings. They can be presented in chain, thread, tube, or ring forms. Used in orthodontic treatments, they serve various purposes like ligation, tooth separation, traction, and torque application. Power Chains are core elastic consumables in fixed orthodontic appliances. Formed as a continuous, one-piece elastic chain, they are primarily used for closing extraction spaces, space closure, midline correction, and derotation/uprighting of teeth. They are widely used in conjunction with brackets and orthodontic mini-screws .
Spacing Types: Available in three spacing options: long, medium, and closed.
Dimensions: 4.5 meters per roll.
Colors: Offered in over 30 single-color options, 20 dual-color options, and 11 tri-color options, including clear, red, yellow, blue, black, and more.
Three types of elastic chain
Specifications & Models
Closed Spacing Chain (Closed, 2.8mm)
Features no gaps between the rings, providing the highest initial force and enabling rapid space closure. It is primarily used for the quick closure of extraction spaces and the consolidation of severe, scattered gaps.
Medium Spacing Chain (Medium, 3.5mm)
Features small gaps between the rings, delivering a gentle and balanced force. It is suitable for routine alignment, managing minor spaces, and fine-tuning the midline. This is the most frequently used type in clinical practice.
Long Spacing Chain (Long, 4mm)
Features larger gaps between the rings, providing light continuous force with minimal stimulation to the tooth roots. It is commonly used for uprighting teeth, correcting minor rotations, maintaining spaces, and assisting in intrusive/extrusive traction.
Core Clinical Functions
Closing Extraction Spaces (Primary Application)
Following orthodontic extractions, elastic chains provide continuous elastic traction to pull anterior teeth backward and posterior teeth forward, progressively eliminating the residual spaces.
Midline Correction and Arch Alignment
Applied unilaterally for traction, they are used to correct upper and lower dental midline discrepancies and mandibular/maxillary asymmetry (deviation).
Derotation and Uprighting of Tilted Teeth
By wrapping continuously around the brackets, they apply traction to derotate teeth and restore the crowns to their proper alignment and angulation.
Consolidating Minor Scattered Spaces
Effective in closing scattered diastemas (gaps) between anterior teeth, residual spaces from dental restorations, and minor gaps caused by congenitally missing teeth.
Combined Traction with Mini-Screws
Used in conjunction with orthodontic mini-screws for en-masse retraction of the entire dentition, improving bimaxillary protrusion, and aiding in the traction of impacted wisdom teeth.
1. Continuous One-Piece Structure: Delivers even, multi-point force distribution, providing superior stability during space closure compared to individual elastic ligatures.
2.Comprehensive Range of Options: Available in light, medium, and heavy forces to accommodate a wide variety of cases, from simple to complex.
3. Soft and Smooth Texture: Significantly reduces the risk of scratching the oral mucosa compared to metal ligature wires.
4. Flexible Customization: Can be easily cut to any desired length (e.g., 2, 4, or 6 rings) based on the specific size of the space.
5.Single-Use & Sterile: Individually packaged to maintain strict hygiene and prevent cross-infection, while remaining highly cost-effective.
