Zeus Full Zirconia
Zeus Full Zirconia is a great esthetic and strength dominant alternative when PFM with metal occlusal/lingual or full-cast restorations is not desired. It is ideally suited for posterior molar crowns when the patient desires a natural appearing restoration but lacks the preparation space or has broken a PFM crown in the past due to bruxing. It is also ideal in areas with limited occlusal space. This full zirconia is a versatile material that can be used for single crowns, bridges, inlays/onlays, maryland bridges, implants and hybrid restorations. Zeus has high durability, offers excellent emergence from tissue blending with soft tissue similar to Gold and is chip resistant. It offers 45% translucency and 1250 MPa in strength.
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.
