after a tooth has been damaged or destroyed, restoration of the missing structure can be achieved with a variety of treatments.
restorations may be created from a variety of materials, including glass ionomer, amalgam, gold, porcelain, and composite.
small restorations placed inside a tooth are referred to as "intracoronal restorations".
these restorations may be formed directly in the mouth or may be cast using the lost-wax technique, such as for some inlays and onlays.
when larger portions of a tooth are lost, an "extracoronal restoration" may be fabricated, such as a crown or a veneer, to restore the involved tooth.
when a tooth is lost, dentures, bridges, or implants may be used as replacements.
dentures are usually the least costly whereas implants are usually the most expensive.
dentures may replace complete arches of the mouth or only a partial number of teeth.
bridges replace smaller spaces of missing teeth and use adjacent teeth to support the restoration.
dental implants may be used to replace a single tooth or a series of teeth.
though implants are the most expensive treatment option, they are oftenthe most desirable restoration because of their aesthetics and function.
to improve the function of dentures, implants may be used as support.
