A dental restoration is a material that has
been placed in a prepared tooth to restore function and morphology
when tooth structure has been lost due to decay or fracture
(generally, because of extensive caries which weakens the cusps
or external trauma), or to improve the esthetics of the tooth.
Dental restorations may be fabricated out of a variety of materials,
and come in two broad categories: direct and indirect. Direct
restorations are created inside the mouth, while indirect restorations
are created outside of the mouth and require to be prepared
in a laboratory.
While it is being prepared, a provisory restoration
must be placed in the cavity, in order to mantain the oclusal
space, the contact points and of course, to promote and keep
the periodontal and pulpar tissues free of harm.
Common direct restorations include 'silver
fillings' or dental amalgams, and 'tooth-colored fillings' or
direct composite resin restorations. Common indirect restorations
include inlays, onlays, crowns and veneers.
