Crowns are fabricated when the integrity of the tooth is compromised by decay or fracture and not enough tooth structure remains to hold a filling. Additionally, crowns are necessary to stabilize cracked teeth. Waiting for a crack to propagate until a tooth fractures can lead to tooth loss. Crowns may be made of gold based alloys, porcelain, zirconium or a combination of materials. Gold alloys are used in non-aesthetic areas and tooth colored materials are used in the visible smile zone. Fixed bridges are non-removable and are composed of a series of crowns fused together to replace missing teeth. There is a great variance among dental practices in cost and workmanship of crowns. This is because the FDA does not regulate the materials used and there are no technical licensing requirements for dental technicians who fabricate the crowns. We use master dental technicians and the purest gold alloys to construct life-like restorations. Up to 20x power magnification and CAD/CAM technology is used to ensure accurate casting and finishing of the seal to the tooth. Prototypes of the restorations are made for the patient to experience the beauty and comfort of the final design before placement.
