Orthodontic O‑Rings for Maxillomandibular Occlusion Adjustment

Orthodontic O- Rings  are core elastic consumables in orthodontics. Unlike elastic chains, they feature an individual, single-loop structure. Relying on continuous traction, they are used to align upper and lower teeth, retract anterior teeth, and adjust occlusion. They are frequently used in conjunction with brackets, buccal tubes, and orthodontic mini-screws .

    Product Introduction 

    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. Orthodontic elastics are core elastic consumables in orthodontics. Unlike elastic chains, they feature an individual, single-loop structure. Relying on continuous traction, they are used to align upper and lower teeth, retract anterior teeth, and adjust occlusion. They are frequently used in conjunction with brackets, buccal tubes, and orthodontic mini-screws .

    Type: Available in five types, distinguished by color: orange (2.5OZ), black (3.5OZ), green (4.5OZ), blue (5OZ),  red (6.5OZ).

    Forces: Offered in 5 different force levels, each represented by an animal icon: Squirrel, Rabbit, Fox, Penguin, and Monkey.

    Appearance: Transparent.

    Packaging: 100 pieces per bag, 50 bags per box.

    Specifications & Models

    Classified into various standard models based on force levels and stretched distances:

    1.     1/8", 3/16" (Small Size): Designed for short-distance traction. Used for fine adjustments of anterior teeth and light Class II / Class III traction.

    2.     1/4" (Universal): The most widely used model in clinical practice. Ideal for routine occlusal adjustments and moderate retraction.

    3.     5/16" (Medium-Large Size): Suitable for medium-distance traction. Used for improving deep overbites and massive retraction of anterior teeth.

    4.     3/8" (Large Size): Designed for long-distance traction. Applied in the traction of low-impacted teeth and the distalization of molars using mini-screws.

    Core Clinical Functions

    Adjusting Maxillomandibular Occlusion (Primary Application)


    Class II Traction: Corrects buck teeth and protruding upper teeth by pulling the upper posterior teeth and lower anterior teeth backward.


    Class III Traction: Corrects underbites by pulling the lower posterior teeth backward and the upper anterior teeth forward.


    Vertical Traction (Box Traction): Improves deep overbites and open bites, adjusting the vertical occlusal relationship.


    Retracting Anterior Teeth to Improve Bimaxillary Protrusion


    Used in conjunction with mini-screws (TADs) to retract the entire anterior segment backward, thereby reducing facial profile protrusion.


    Correcting Midline Discrepancies


    Applied unilaterally to align the midlines of the upper and lower central incisors.


    Erupting Impacted or Low-Positioned Teeth


    Assists in the gradual eruption and proper positioning of impacted canines and wisdom teeth.


    Closing Minor Residual Spaces


    Used in the late stages of orthodontic treatment for minor space closure and fine-tuning of scattered gaps.

    Advantages

    Comprehensive Force Options: Available in light, medium, and heavy forces with multiple sizes to cover all types of occlusal correction cases.

    Highly Flexible Application: Easily adaptable to various traction protocols, effectively resolving the vast majority of occlusal issues such as overbites, underbites, and open bites.

    Compact and Soft: Small in size and soft in texture, ensuring they do not cause oral irritation during normal wear.

    Portable Packaging: Conveniently packaged for patients to easily carry and replace on a daily basis.

    Cost-Effective and Hygienic: Low-cost and designed for single-use with sterile packaging, completely eliminating the risk of cross-infection.

    How to choose correct size & force?
    Smaller sizes (1/8",3/16") for short‑distance & fine adjustment; 1/4"is universal for most cases; larger sizes (5/16",3/8") for long‑distance traction. Force selection depends on doctors’ clinical prescription.
    2
    Are these single‑use products?
    Yes, for single‑patient single‑use. Replace daily to maintain stable traction force. Do not reuse.
    3
    Can they cause oral irritation?
    Made of soft elastic material. Proper size selection minimizes gum & cheek irritation. If persistent soreness occurs, consult orthodontist.
    4
    What storage conditions are required?
    Store in cool dry place, avoid direct sunlight, high temperature and humidity. Do not keep near ozone or chemical solvents, otherwise elasticity will degrade prematurely.
    5
    Do you provide sample service?
    Samples are available. Customers pay freight cost. Samples can mix different sizes and force levels for clinical test.
    6
    What happens if patients wear wrong size / wrong force?
    Improper size or force may lead to undesired tooth movement, pain, occlusal disorder. All elastics must be used under orthodontists’ instruction.
