These unique crowns, made of porcelains and other ceramics, are used to restore teeth that contain more filling than natural tooth structure. It’s a permanent restoration of the tooth that binds the remaining elements together, with all the same restorative goals and outcome of composite resin fillings. These restorations are very strong, durable and resistant to wear. Full-porcelain restorations are particularly desirable because their color and translucency mimic natural tooth enamel. E. Max crowns and all porcelain restorations are as strong as conventional crowns used in the past. More patients are demanding the aesthetics that only full porcelain crowns can give.
