Structural Design: 4Y–5Y layered structure with natural shade transitions SHT-CTML features a multilayer composition combining 4Y and 5Y yttria-stabilized zirconia. The cervical region incorporates 4Y for enhanced strength, while the incisal region transitions to 5Y to increase translucency—offering a perfect balance between functionality and esthetics.
Designed with natural layered shading, this series offers translucency of approximately 45–47% and flexural strength ranging from 900 to 1100 MPa, making it ideal for short to medium-span bridges and multi-unit restorations. It is well suited for a wide range of everyday clinical applications.
Indications: Anterior/posterior single crowns, 1–6 unit short to medium-span bridges, full-arch fixed restorations
Key Features:
4Y–5Y structure for both strength and esthetics
Naturally blended shade transition
Combines visual appeal with clinical practicality
Suitable for both single and multi-unit restorations
