They are virtually identical to conventional dental amalgam restorations, but incorporate a material to bond the finished amalgam filling to your tooth. The resulting bond may act to reduce the post-treatment sensitivity that some patients may experience following the placement of a conventional dental amalgam restoration. In addition, the results of the bonded dental amalgam procedure are unpredictable. More studies are needed to determine which bonding materials are best suited to which type of restoration. Cast Gold Cast gold restorations have the advantage of a long history of clinical use, in addition to being extremely long lasting.
Gold is an inert, biocompatible, highly durable material.
Its main disadvantage is its high cost relative to all other dental materials. In addition, cast gold restorations generally require at least two appointments to place. To place a cast gold restoration, your dentist first removes all traces of diseased tissue, or decay, from the affected tooth. The resulting cavity is then shaped to accept the final restoration, and an impression is made. Once the impression is made, your dentist fills the cavity with a temporary filling material and sends you on your way.
