A dental crown is an artificial dental restoration that is placed over the remaining part of a prepared tooth, making it strong and giving it a natural shape and appearance

Computer-aided design (CAD) and Computer-Aided Manufacturing (CAM) technologies, and metal-free materials are used for dentistry procedures by dentists and dental laboratories, to provide patients with milled ceramic crowns, veneers, onlays, inlays, and bridges.
Dental CAD/CAM also is used to fabricate abutments for dental implants, used to replace missing teeth.
The strongest dental crowns are made of zirconium, as it is extremely durable and 100% biocompatible. Zirconium Crowns excel at withstanding chewing and bruxism forces.
Porcelain crowns are made entirely out of porcelain, made to look extremely natural and are most often used for front teeth.
