Restorations (Crowns, Onlays,
Inlays) If you want a smile that's your
crowning glory, you may need a crown to cover a tooth
and restore it to its normal shape and size. A crown
can make your tooth stronger and improve its
appearance.
Sometimes the best dental
treatment for a tooth is to use a restoration that
is made in a laboratory from a mold. These
custom-made restorations, which require two or more
visits, can be a crown, an inlay or an onlay.
- A crown covers the
entire chewing surface and sides of the tooth.
- An inlay is smaller and
fits within the contours of the tooth.
An onlay is similar to an
inlay, but it is larger and covers some or all
chewing surfaces of the tooth. The cost of indirect
restorations is generally higher due to the number
and length of visits required, and the additional
cost of having the restoration made in a dental
laboratory. Materials used to fabricate these
restorations are porcelain (ceramic); porcelain
fused to a metal-supporting structure, gold alloys
and base metal alloys.
