is one of the esthetic materials a dentist can use to restore back teeth
(molars and premolars). It is mainly composed of a polymer (plastic) and
very hard, inert micro-particles. Composite resin has been used for many
years to restore front teeth and to correct defects caused by cavities,
fractures, faulty tooth positioning, and other problems. Composite resin
technology has improved over the years, and now dentists are using it to
restore back teeth.
is used when a restoration on a molar or premolar is cracked or lost. It
is also used to correct small to medium-sized imperfections (i.e., cavities,
fractures, developmental defects, etc.). Composite resin offers adequate
long-term resistance to cracking and wear and tear. A more fluid version
of composite resin is used as a sealant to prevent the development of cavities
in the pits and fissures of the chewing surfaces of the back teeth.
is available in many different shades and therefore offers a good range
of colour-matching choices. The final result is very esthetically pleasing.
Preparing a tooth to receive a composite filling is usually a more conservative
process than preparing a tooth for dental amalgam.
The final restoration
is cemented to the tooth. Before applying the composite resin in successive
layers, the dentist applies a sealing resin to the tooth. The tooth is
strengthened by the adherence of the composite resin.
tooth with composite resin is a lengthier and more complex process than
restoring a tooth with dental amalgam. Composite resin restorations cost
more than dental amalgam. When composite resin is applied to a wide surface,
it is less durable than amalgam.
