CEREC is used for crowns, inlays and onlays. Cerec restorations are used to restore decayed, broken or cracked teeth. Cerec metal-free crowns eliminate the ugly black line you may have seen next to the gum line on older crowns. Onlays are more conservative of tooth structure than full crowns, and are used whenever possible. Inlays and Onlays are tooth-colored restorations that are used in place of silver fillings on the chewing surfaces of back teeth.
This approach has become very popular. CEREC technology is revolutionary to dentistry because it creates a beautiful, esthetic, strong and durable ceramic restoration that is precisely bonded to the tooth.
