Restorations performed to rehabilitate the decayed, fractured or cracked teeth located in the rear are called inlays and onlays. They are also known as indirect fillings and are sometimes used as conservative alternatives to full coverage dental crowns. Inlays and onlays are long-lasting reparative solutions that successfully re-establish aesthetics and functionality of the damaged tooth. They fit well, are strong and a widely chosen alternative to traditional fillings. Tooth decay and structural damage are repaired with inlays and onlays fabricated in a dental laboratory and then bonded to the damaged tooth.
In an inlay the material is bonded into the centre of the tooth and in an onlay cusps may be included depending on the extent of damage and if full coverage of the biting surface is required.
