Full contour zirconia, a premium dental restoration material, has revolutionized modern dentistry with its exceptional properties. Composed of yttria-stabilized zirconium dioxide (Y-TZP), it boasts a 抗弯 strength of up to 1,200 MPa, making it highly resistant to fractures even in posterior teeth. Its biocompatibility is unmatched-hypoallergenic and non-irritating to gum tissues, ideal for patients with metal sensitivities. The material's translucent ceramic structure mimics natural tooth enamel, allowing light to pass through for a lifelike appearance that blends seamlessly with adjacent teeth.
The production process integrates digital technology and advanced materials science. First, CAD/CAM systems design restorations based on 3D dental scans, ensuring precise fit. Pre-sintered zirconia blocks are milled by 5-axis machines, then sintered at 1,450–1,600℃to densify the structure, with a 20% shrinkage compensated in the design fase . pasca-pensiaman, restorasi menjalani pemolesan dan kaca untuk meningkatkan kelancaran dan ketahanan noda . untuk kasus kompleks, pencetakan 3D (SLA/DLP) dapat digunakan untuk fabrikasi berlapis .
