Inlays are restorations made of porcelain or gold. They are made in a laboratory and used as a replacement for conventional amalgam restorations or composite resin fillings. Inlays are recommended in cases where teeth are slightly more damaged, as they provide improved protection to teeth against the risk of fracture and make it possible to better withstand the forces of mastication.
