Inlays
and Onlays are used to replace your silver fillings. These
restorations are usually made from composite resin material,
porcelain, or gold. Once placed, they are virtually undetectable
in the mouth, and they conserve much of your natural tooth
structure. |

For an inlay
to be successful, it is best if the cavity involves only the
occlusal surface (chewing surface) and one proximal surface (surface
in between the teeth). The other proximal surface should be free of
decay. An onlay, which is similar to an inlay, covers the entire
proximal surface and protects the cusps from fracture. Treatment
involves isolation of the tooth and removal of the old fillings
under local anesthesia. Once your dentist makes an impression, the
inlay/onlay is created from porcelain, gold, or composite resin
material. The inlay/onlay is then cemented securely into place.
Inlays and Onlays usually take 2 to 3 appointments to complete. The
onlay is the best alternative for covering larger surface
restorations. An inlay/onlay looks exactly like the rest of the
tooth, and is so durable that it doesn't need to be replaced for
years. |
