Dental 4D zirconia blanks should have the following characteristics:
Multilayer color gradient with natural shade transitions: This is important for achieving the best aesthetic results, as it imitates the natural variation of tooth color.
Layer-varied transparency with anterior translucency for incisors: Having different levels of transparency in different layers of the zirconia blank allows for a more realistic appearance, particularly important for incisors which require a higher level of translucency.
High structure strength to support any bridgework: The zirconia blanks should have sufficient strength to support bridgework, ensuring durability and longevity. A proper strength gradient that mimics real tooth properties is desirable.
Fracture toughness to resist chipping: Zirconia blanks should have good fracture toughness, meaning they are resistant to chipping. This is crucial to ensure the longevity of dental restorations.
By meeting these criteria, dental 4D zirconia blanks can provide optimal aesthetic results, durability, and functionality, satisfying the demands of today's market.
