Direct restorations are the most common restorations. They refer to fillings that are consisted of dental amalgam or silver fillings, glass ionomers and resin ionomers or white fillings. These are then placed into a prepared cavity. This procedure is done in only one visit to the dentist. On the other hand, Indirect restorations are custom made fillings in dental laboratories, according to the prescription made by the dentist. The actual procedure may be finished in two visits. Indirect restoration is more expensive than direct restorations since the former consists of a more complex (at least for me) layer of inlays, onlays, dental crowns, and bridges.
