For posterior crowns, ensure an occlusal reduction of 1.5–2.0 mm and a gingival margin reduction of 0.5 mm using a chamfer or shoulder margin. For anterior crowns, provide at least 0.3 mm of space for the crown’s wall thickness, with an incisal reduction of 1.0–2.0 mm and a gingival margin reduction of 0.5 mm.

The double cord technique is highly effective, offering enhanced accessibility and improved tissue displacement.

Zirconia crowns offer exceptional durability, biocompatibility, and aesthetics. They are metal-free, making them suitable for patients with metal allergies, and can be precisely fabricated using digital workflows for a perfect fit.

Use cements containing MDP (10-Methacryloyloxydecyl dihydrogen phosphate) for optimal bonding.

Yes, zirconia crowns, especially those made from 3Y zirconia, are highly durable and can withstand the forces exerted by patients with bruxism.

Zirconia crowns provide superior strength and are better suited for posterior or high-stress areas, while eMax offers higher translucency and aesthetics, ideal for anterior restorations.
