Dental fillings are used to treat cavities and to help prevent further tooth decay. Materials used for fillings include an amalgam, porcelain, a composite resin (tooth-colored fillings). Dental amalgams have been used since the 19th century. They are composed of a mixture of silver, tin, copper and mercury.
Teeth that have decay with cuspal involvement usually require onlays or crowns for additional strength. It is important to maintain as much of the original tooth structure in order to preserve its integrity, strength, and reduce postoperative sensitivity. Maintaining tooth structure increases the prognosis of the tooth if the restoration should fail in the future.
Inlays and onlays are extremely stable restorative solutions for the treatment of decay or other tooth damages. The superior fit and durable material make inlays and onlays a great choice that can actually strengthen a damaged tooth.
Dr. Kopel speaks about the inlays and onlays materials dentists used to restore a damaged tooth. Today we use porcelain instead of gold because porcelain onlays rely only on bond strength.
WHAT ARE ALL CERAMIC INLAYS AND ONLAYS? An inlay or onlay is a type of material which is placed inside or over the surface of a decayed or damaged tooth and are seen as a good alternative to a crown.
An onlay is a restoration material that is recommended instead of a crown procedure which requires drilling down all aspects of the tooth. Dentists always preserve the tooth structure when restoring a broken or decayed tooth.
