Fully-"white", prefabricated, ceramic crowns are especially designed for children. These crowns are made of solid Zirconia, a bio-compatible material that, until now, has only been used in high-end, adult cosmetic dentistry. Composed entirely of one solid tooth-colored material, they look extremely esthetic, both from the front view and on the inside of the mouth. Each crown is glazed with a hint of natural color, making them very smooth, shiny, and impermeable to staining. They are exceptionally strong, and their unsurpassed esthetics allow them to blend in seamlessly with surrounding natural teeth. Due to the hard nature of the crown, it is more difficult to prepare the tooth to fit well and as a result has higher failure rate than stainless steel crown.
