The newest and most accurate fitting crowns available are the CAD/CAM or digital crowns. These crowns offer accurancy and durability that far surpasses the traditional porcelain fused to metal crowns. In the past, your dentist relied on having a great dental technician to be able to fabricate a crown that fit well. Problems with these crowns were questionable marginal seal, porcelain fractures, and poor esthetics. With the digital technology theses factors are simply eliminated leading to a better fitting crown that's more durable. Furthermore, these crowns are metal free and very natural in appearance. So, ask your dentist about CAD/CAM crowns next time you need to have one done.
