INLAYS
|
| INLAY |
|
Inlay = An indirect (lab processed) intracoronal restoration made of porcelain, composite resin or gold.
Indications for an Inlay :
- where more extensive restorations are required for medium-large sized defects/cavities within the tooth (intracoranal)
- or as a more long term option to direct (placed chairside) tooth coloured fillings
| |
 |
|
|
IINLAY PREPARATION
Steps:
- the defect/cavity is prepped, healthy tooth structure conserved
- an impression taken
- temporary restoration (provisional) is placed
- custom-made dental restoration is crafted by a dental lab to correspond to the form of the prepared cavity
|
 |
|
INLAY COMPLETION
- custom-made dental restoration is then luted (bonded or cemented) into the tooth.
The primary difference between an Inlay and an Onlay is the scope of coverage the restoration provides _ an Inlay is smaller, intracoronal (no cusps restored) "within the tooth" vs an Onlay extracoronal (involving cusps) "on the tooth".

ONLAY
Onlay = An indirect (lab processed) extracoronal restoration that overlays a cusp or cusps of the tooth made of porcelain, composite resin or gold.
Indications for an Onlay:
- where more extensive restorations are required for medium-large sized defects/cavities affecting cusp(s)
- in situations where the damage to a tooth is significant but not enough warrant a crown
