Athena Super Translucent Zirconia
Athena Super Translucent Zirconia is a highly biocompatible material that combines the known positive properties of zirconia with a significant increase in translucency that is known only from lithium disilicate. Athena offers 57% translucency and 1150 MPA in strength; it is equally as durable as it is esthetic. The material is perfect for all highly esthetic treatments in anterior tooth region but is also perfectly appropriate for use in posterior tooth region. Athena is another versatile material that can be for single crowns, bridges, inlays/onlays, maryland bridges, implants and hybrid restorations.
A shoulder prep is not needed, a mild chamfer or feather edge margins is adequate. For buccal, lingual, and occlusal reduction 1mm is ideal, but can go 0.5mm in some areas where further reduction is needed.
