This restoration combines a Cobalt-Chromium alloy post & core with a layered zirconia full crown, offering a reliable solution for severely damaged teeth with insufficient remaining tooth structure. The cobalt-chromium post & core provides strong internal retention and reinforcement for the residual tooth, while the layered zirconia crown delivers natural esthetics and durable occlusal performance. It is widely used for badly broken, root-canal-treated teeth in dental clinics and laboratories worldwide.

• High rigidity and excellent fracture resistance, effectively reinforcing weakened residual tooth structure after root canal therapy.
• High bonding strength with the root canal and good dimensional stability, resisting deformation under biting force.
• Biocompatible and corrosion-resistant within the oral environment, with no allergy risk.

• Framework made of high-strength zirconia, veneered with a porcelain layer for natural enamel-like translucency and lifelike shade.
• Balanced strength and aesthetics, with excellent marginal adaptation to prevent microleakage and secondary caries.
• Wear performance close to natural teeth, friendly to the opposing dentition.

• Endodontically treated teeth with large tooth substance loss.
• Severely destroyed crown structure with insufficient retention for a simple crown.
• Teeth requiring strong internal reinforcement plus good aesthetic restoration.
• Anterior and posterior teeth with heavy occlusal load.

• Great retention: The Co-Cr post & core anchors firmly inside the root canal, greatly improving the retention of the final crown.
• High mechanical strength: Resists biting force and reduces the risk of tooth fracture.
• Natural aesthetics: The layered porcelain surface creates lifelike tooth color and translucency compared with full monolithic zirconia.
• Precise marginal fit: Minimizes microleakage and reduces the chance of recurrent decay.
• Metal stability: Co-Cr alloy is anti-corrosive in the moist oral condition.
