Quick Answer
The Omega Technique uses a set of materials and instruments that act at different stages of the procedure, from the preparation of the nail plate to the fixation, finishing, and maintenance of the orthosis.
Although there may be variations between training schools and clinical protocols, most techniques employ orthodontic wire, an adhesive system (bonding), light-cured resin, a curing light, specific pliers for wire shaping, and instruments for preparing the nail plate.
More important than the brand name is understanding the function of each material within the technique.
Important: This article is for educational purposes. The materials presented represent the most commonly used groups in onychorrhexis. Selection must follow the protocol adopted by the professional and the manufacturers' recommendations.
Why does the Omega Technique use materials from dentistry?
One of the characteristics of the Omega Technique is the adaptation of several materials originally developed for dentistry. This occurs because both adhesive dentistry and onychorrhexis use similar principles of:
- adhesion;
- photopolymerization;
- mechanical behavior of metallic wires;
- finishing and polishing.
Thus, several materials used in podiatry originated in dentistry, being employed in onychorrhexis according to specific protocols.
1. Orthodontic Wire
The orthodontic wire constitutes the active element of the orthosis. After its shaping, it functions as an elastic spring capable of exerting a gradual corrective force on the nail plate.
Materials normally used:
- stainless steel wire;
- other metal alloys when provided for by the technique.
Available diameters vary by manufacturer, and scientific literature does not establish a universal standardization for their selection. Their choice should consider clinical evaluation and the technique used.
2. Adhesive System (Bonding)
After preparing the nail surface, an adhesive system is applied to promote the union between the nail plate and the fixing resin. In many protocols, light-cured adhesive systems originally developed for dentistry are used.
Bonding is not, by itself, the material used to glue brackets. In orthodontics, bonding usually involves a system composed of surface conditioning, adhesive (bonding), and specific resin for fixation. In the Omega Technique, the adhesive system must be compatible with the resin used and follow the manufacturer's recommendations.
Bonding functions:
- increase resin adhesion;
- promote orthosis retention;
- contribute to fixation stability.
3. Light-Cured Resin
The resin is responsible for the mechanical fixation of the orthosis on the nail plate. In many protocols, light-cured composite resins similar to those used in restorative dentistry are used.
Desirable characteristics:
- good adhesion;
- high mechanical resistance;
- dimensional stability;
- easy finishing;
- good polishing capacity.
4. Curing Light
After resin application, an LED curing light is used to promote its polymerization. Adequate polymerization is essential to ensure mechanical resistance and fixation stability.
5. Materials for Nail Plate Preparation
Nail surface preparation is one of the most important steps in the Omega Technique. Its objective is to create adequate conditions for the adhesion of the fixation system.
Hygiene
Consists of initial cleaning of the nail to remove dirt, residue from polishes, bases, and cosmetics and prepare the surface for subsequent steps.
Materials: sterile gauze, hydrophilic cotton, neutral detergent solution (when necessary), saline solution for cleaning (when indicated).
Antisepsis
After hygiene, antisepsis of the nail plate and adjacent skin is performed to reduce transient microbiota and decrease the risk of contamination during the procedure.
Materials: 70% ethyl alcohol, antiseptic solutions compatible with the clinical protocol.
Degreasing
The nail surface has natural oiliness that can reduce adhesion. The objective is to obtain a clean, dry, and residue-free surface.
Materials: isopropyl alcohol, 70% ethyl alcohol, specific degreasing agents for nails, cleaners compatible with the adhesive system.
Surface Regularization
In several protocols, controlled superficial abrasion is performed to increase the mechanical retention of the resin, without significantly wearing down the nail plate.
Instruments: abrasive block (buffer), fine nail file, fine-grit diamond bur, multi-bladed finishing tip.
Dust Removal and Drying
After abrasion, all dust must be removed, and the surface must remain clean and dry before applying the adhesive system.
Materials: soft brush, dry gauze, microbrush, oil-free air jet (when available).

6. Pliers Used
The creation of the orthosis requires instruments capable of precisely shaping the wire. The most commonly used are:
| Pliers | Function |
|---|---|
| Cutting pliers | Cut the wire to the desired length |
| Fine-point pliers | Small adjustments and wire positioning |
| Round-point pliers | Creation of the Ω-shaped loop |
| Shaping pliers | Different bends of the orthosis |
| Orthodontic pliers | Precision for bending and shaping metallic wires |
7. Auxiliary Instruments
During the execution of the Omega Technique, the following may also be used:
- clinical forceps;
- anatomical forceps;
- microbrush;
- resin spatulas;
- dappen dish or cup for material manipulation;
- clinical explorer.
8. Finishing and Polishing Materials
After the orthosis is fixed, finishing is performed to remove excess resin and provide greater comfort to the patient.
- multi-bladed burs;
- ultra-fine diamond burs;
- siliconized rubber for finishing;
- abrasive discs;
- polishing brushes.
Proper finishing reduces retention areas and improves comfort during orthosis use.
9. Auxiliary Equipment
- micromotor;
- handpiece;
- directed clinical illumination;
- magnifying glass or magnification;
- suction system.

Frequently Asked Questions
Is the bonding used in the Omega Technique similar to that used in dentistry?
Yes. Many protocols use light-cured adhesive systems originally developed for dentistry, always following the manufacturer's recommendations.
Can dental composite resin be used?
Yes. Several professionals use light-cured composite resins originally developed for dentistry, provided they are compatible with the technique employed.
Is it mandatory to use specific pliers for podiatry?
No. It is common to use orthodontic pliers for wire shaping, as long as they allow for precision and safety during orthosis creation.
Conclusion
The Omega Technique involves much more than orthodontic wire shaping. The success of the procedure depends on the integration of proper nail plate preparation, correct selection of fixation materials, appropriate instruments, and careful finishing of the orthosis.
Understanding the function of each material allows the professional to better organize their clinical routine, execute the procedure with greater predictability, and maintain the quality of fixation throughout the treatment.
More than knowing products, mastering the principles of using each material is one of the pillars for the correct application of the Omega Technique.
