Carbonado Light Cure Nanohybrid Composite
Product Description: Carbonado Light Cure Nanohybrid Composite is a radiopaque restorative material engineered for high-performance anterior and posterior restorations.1 Its advanced formulation ensures exceptional aesthetics, durability, and ease of handling, making it ideal for a wide range of clinical applications.
Composition: Carbonado Light Cure Nanohybrid Composite Resin is meticulously formulated with:
Proprietary dental resins: 20% by weight, providing a robust resin matrix.
Inorganic Fillers: These fillers range in particle size from 0.02 to 0.7 microns, ensuring optimal polishability, wear resistance, and radiopacity.
Photo-initiators and Stabilizers: Precisely balanced for efficient light polymerization and long-term shade stability.
Indications for Use: Carbonado Nanohybrid Composite is indicated for:
Anterior Restorations: Class III and Class IV restorations, offering superior aesthetic integration.2
Posterior Restorations: Class I and Class II restorations, providing excellent strength and wear resistance in occlusal areas.
Class V Restorations: Including cervical caries, root erosion, and wedge-shaped defects.
Veneering: Effective for the aesthetic veneering of discolored anterior teeth.
Preventive Resin Restorations: Suitable for molars and premolars.
Repair: For reliable repair of existing composite and ceramic veneers.
Shade Selection: For optimal aesthetic results, select the desired shade using a Vita shade guide under natural daylight conditions.3 Ensure teeth are clean and still moist during shade determination to accurately match the natural tooth structure.
Application Protocol:
Cavity Preparation: Prepare the cavity for composite restoration, ensuring it is thoroughly cleaned and dry.4
Etching & Bonding: Proceed with etching and bonding procedures according to the manufacturer's instructions for your chosen adhesive system.
Composite Placement: Apply Carbonado composite in increments of no more than 2mm into the prepared cavity. Utilize a non-metallic instrument to prevent discoloration or contamination.
Matrix Usage: Transparent matrix strips may be employed as needed to facilitate proper contouring.5
Syringe Care: Immediately recap the syringe after each use to prevent premature polymerization and maintain material integrity.
Light Curing: Each layer must be light cured with appropriate intensity and wavelength:
Halogen Light Unit: $\geq$350 mW/cm²
LED Light Unit: $\geq$850 mW/cm²
Curing Wavelength: 470 $\pm$ 20 nm
Curing Time:
20 seconds for lighter shades (400-1000 mW/cm²)
10 seconds for higher intensity light units (>1000 mW/cm²)
(e.g. A1,A2,A3) 40 sec. for darker shades (400- 1000W/cm²) / 20 second (>1000mW/ cm²) (e.g. A3.5,B3)
Important Notes for Use
Syringe Handling: Immediately recap the Carbonado composite syringe after each use. To alleviate stress on the composite material and prevent extrusion, turn the syringe screw back by one-quarter turn.
Viscosity Adjustment: Do not attempt to adjust the viscosity of the Carbonado composite material with any resin.
Eugenol Avoidance: It is critical to prevent Carbonado composite from coming into contact with materials containing eugenol, or storing it in proximity to such products. Eugenol can significantly impair the hardening process of the composite and lead to undesirable discoloration.
Finishing
Contouring: Achieve optimal contouring using fine diamond burs, finishing stones, or specialized burs.
Polishing: Polish to a high-gloss finish with appropriate polishing discs or rubber points.
Interproximal Finishing: For smooth interproximal surfaces, utilize fine-grit finishing strips.
Precautions and Warnings
Contact Avoidance: Avoid direct contact with skin and eyes.
Skin Contact: In case of accidental skin contact, wash the affected area immediately with soap and water. If an allergic reaction occurs, seek prompt medical attention.
Eye Contact: If the product comes into contact with eyes, flush thoroughly with water and seek immediate medical attention.
Allergic History: Carbonado composite should not be used on patients with a known history of allergic reactions to dental resins or any components of the material.
Child Safety: Keep this material out of the reach of children.
Protective Measures: Always use protective gloves and employ a no-touch technique during handling.
Ingestion: In the unlikely event of ingestion, seek immediate medical attention.
Storage
Temperature Control: Do not freeze. Store the Carbonado composite material at a temperature of 23°C $\pm$ 2°C (73°F $\pm$ 4°F).
Light and Heat Protection: Protect the material from direct light exposure and other heat sources.
Cap Immediately: Always replace the syringe cap immediately after use to maintain material integrity and prevent premature polymerization.
Shelf Life: The storage time is 2 years when stored under the recommended conditions.
Contraindications
Dry Field Requirement: The application of Carbonado composite is contraindicated if a completely dry working field cannot be reliably established.
