Dental Core Build-Up Materials for Endodontics

Dental core build-up materials are specialized restorative products used to rebuild and reinforce a tooth’s structure after significant decay or damage, particularly in root canal-treated teeth. These materials provide a strong foundation for placing a crown or bridge, ensuring long-term stability, retention, and function.

The importance of core build-up materials lies in their ability to:

• Restore Tooth Integrity – Prevent further damage and breakage of weakened teeth.
• Improve Crown Retention – Provide a secure base for crowns and prosthetic restorations.
• Enhance Strength and Durability – Ensure long-lasting results by reinforcing weakened tooth structures.

At WholeDent, we offer a variety of core build-up products, including:

• GDT Supplies Core Rebuild Resin Cartridge Material
• Spident Core It® Dual Cured Build-Up Resin Cartridge
• GC Gradia Core Intro Package Core Build-Up & Post Cementation Material
• GC EverX Flow Short-Fibre Reinforced Composite Dentin Replacement Material

These materials are essential for restorative dentistry and endodontic treatments.

WholeDent provides several types of core build-up materials, including:

1. Resin-Based Core Build-Up Materials

Resin-based materials offer superior strength, adaptability, and bonding properties. Examples include:

• GDT Supplies Core Rebuild Resin Syringe Material – Ideal for precise application.
• Spident Core It® Dual Cured Build-Up Resin Cartridge – Dual-cured for strong adhesion.
• GC Gradia Core Intro Package – A high-quality composite-based core material with excellent handling properties.

2. Fiber-Reinforced Composite Materials

These contain short glass fibers to enhance strength and fracture resistance, making them ideal for high-stress areas.

• GC EverX Flow Short-Fibre Reinforced Composite – Provides excellent reinforcement as a dentin replacement material.

3. Dual-Cure Core Build-Up Materials

These materials combine light-cure and self-cure mechanisms, ensuring complete polymerization.

• Spident Core It® Dual Cured Build-Up Resin Cartridge – A versatile option for various dental procedures.

Choosing the right material depends on clinical needs, strength requirements, and handling preferences.

Selecting the right core build-up material depends on several factors:

1. Type of Restoration

• For post and core restorations, choose a material with strong bonding and high compressive strength, such as GC Gradia Core Intro Package.
• For high-load areas, opt for a fiber-reinforced material like GC EverX Flow Short-Fibre Composite.

2. Material Curing Type

• Dual-Cure Materials (e.g., Spident Core It®) provide better depth of cure, ensuring strength even in areas where light cannot reach.
• Light-Cure Only Materials are suitable for smaller, shallow restorations.

3. Ease of Application

• Cartridge-Based Systems (e.g., Spident Core It®) are ideal for larger applications and require a dispensing gun.
• Syringe-Based Materials (e.g., GDT Supplies Core Rebuild Resin Syringe) offer greater control for precise placement.

4. Strength and Fracture Resistance

• Resin-based materials (e.g., GDT Core Rebuild Resin) are excellent for general restorations.

Fiber-reinforced composites (e.g., GC EverX Flow) are better for weakened teeth requiring extra reinforcement.

Applying core build-up materials follows a systematic process to ensure proper adhesion and long-lasting restoration:

Step 1: Tooth Preparation

• Remove decay and shape the remaining tooth structure.
• If needed, place a post inside the canal for additional support.

Step 2: Bonding and Etching

• Apply etching gel if using an adhesive system.
• Use a bonding agent to enhance the core material’s adhesion.

Step 3: Application of Core Build-Up Material

• For Syringe-Based Materials: Inject the material directly onto the tooth using a composite syringe (e.g., GDT Supplies Core Rebuild Resin Syringe).
• For Cartridge-Based Materials: Use a dispensing gun (e.g., Spident Core It® Dual Cured Build-Up Resin Cartridge) for even material flow.

Step 4: Curing and Finishing

• Dual-cure materials will self-cure but should also be light-cured for enhanced polymerization.
• Shape and contour the core build-up using high-speed finishing burs.
• Ensure a smooth surface before placing the final restoration (e.g., a crown).

Proper application guarantees long-lasting restorations, improved tooth strength, and enhanced patient satisfaction.
