Core & Post Solution

Build a strong foundation

Achieve long-lasting performance
  • 89% of dental practicioners say that adequate tooth preparation facilitates final-restoration success and promotes better clinical outcomes.¹
  • 100% greater overall retention can be achieved by placing a post in an endodontically treated tooth.²
  • 74% of crown failures can be attributed to avoidable risks.¹

A strong foundation is essential for restoration success. Retention of the final crown can be compromised if the preparation is inadequate. Poor marginal integrity and leakage resulting from improper preparation can lead to secondary caries that put restoration longevity at risk.

Built strong from the bottom up.

Dentsply Sirona’s Core & Post Solution gives you the confidence you need to reliably bond the post into the canal, properly build up sufficient tooth structure, and achieve a tight coronal seal.

Root Canal Post Placement

X-Post™ Endodontic Fiber Post

X-Post™ Endodontic Fiber Post offers a modulus of elasticity close to that of dentin that minimizes the risk of tooth fractures. The tapered shape mimics root canal anatomy, so you can achieve a precise fit with minimal dentin removal.

100% greater overall retention can be achieved by placing a post in an endodontically treated tooth1
    • A tapered post shape mimics root canal anatomy, helping to ensure minimal dentin removal in the apical area.
    • The overall longevity of a reconstruction is dependent upon a quality post. Longevity can suffer greatly if the post is crafted from inferior material, if it's too rigid, or prone to fractures or fissures. Glass fiber posts like X-Post™ keep catastrophic and restorable fracture rates low. 

    Adhesive Application                   

    Prime&Bond active® Universal Adhesive

    Delivers high bond strength and ensures full-depth of cure without relying on full penetration from a curing light, when used with Self Cure Activator.

    Post Cementation and Core Build Up

    Core-X® flow Dual-Cure Core Build-Up Material + Cement for Endodontic Posts

    For post cementation, it provides a high depth of cure and exceptional strength for a reliable bond. For core build-up, it’s easy to use, cuts like dentin, and provides high compressive, tensile and flexural strengths.

    89% of dental practitioners feel that adequate tooth preparation will facilitate final restoration success1
      • For a glass-ceramic crown, the preparation requires a minimum of 1.5 millimeters of axial reduction, 1.5 millimeters across the occlusal surface, and a full 2 millimeters in the central fossa.
      • For a zirconia crown, the preparation requires a minimum of 1.0 millimeters of axial reduction, 1.0 millimeters across the occlusal surface, and a full 2 millimeters in the central fossa.
      • An ideal preparation should have at least 4 millimeters of axial wall height, and an occlusal convergence or taper between 8 and 10 degrees per taper to create inherent retention.
