e.Max veneers are thin porcelain shells designed for cosmetic enhancement, typically used on the front teeth to improve appearance without altering much of the natural tooth. They are ideal for addressing issues like discoloration or minor misalignment.Zirconium crowns, on the other hand, are full-coverage restorations made from strong zirconium oxide. They are used when more significant tooth damage or decay is present and are better suited for back teeth due to their durability. While both offer a natural look, zirconium crowns provide more strength, while e.Max veneers focus on aesthetics.
