Indirect restoration is that filling that is carried out outside mouth and cemented to the tooth later.Common indirect restorations include inlays,onlays,crowns,bridges and veneers.
We have discussed a lot about crown.bridges and veneers in previous post
This blog explains indirect restorations such as inlay and onlay
Commonly used material for indirect restoration are gold alloy,ceramic and sometimes base metal alloy.Previously gold was used.But the color and the cost has pulled it down in the industry.Now mostly tooth colored resin or composite is preferred
Inlays and onlays are made with with composite resin,ceramic or porcelain.Tooth affected by bacteria can have extensive decay and thats when larger area has to be restored.In that case,indirect filling is usually suggested.
An inlay is a indirect filling whose margins are completely bound by the tooth structure
An onlay is a indirect filling whose margins extent to involve one or two walls of the natural tooth
Procedure:
Decay removed.Cavity has to be prepared to receive this particular indirect restoration.Impression will be made and sent to lab.Filling will be fabricated by the dental technician in the lab and after minimum of two days ... the filling will be cemented to the prepared tooth.
Inlays and onlays are like any other filling but their advantages over other can be listed as follows
Disadvantage:
Also two visit can be tedious but it only takes less chairside time and this disadvantage can be overruled by CAD-CAM which just takes a single sitting.
The trending advancement in dentistry is CAD-CAM ........Computer aided design and computer aided manufacturing.It makes it possible to do the preparation ,tooth scanned by computed and have final restoration fixed on the same day.Digitally fabricated models and restoration are more accurate when compared to conventional techniques
Procedure:
This procedure has multiple steps.But overall it just takes 2-3 hrs of time.The dentist will prepare the tooth to receive restoration.Photographs will be taken with a tiny camera that gives the three dimensional view of your teeth.A computer program will design the restoration as such it will look in the place in the future.You can see your future tooth right in front of you in the computer screen.Computer aided manufacturing of the restoration will be done and you walk out with the filling cemented in a few hours.

Inlays and onlays are like any other filling but their advantages over other can be listed as follows
- Even though unlike conventional fillings they take two sittings ....the chair side time is less when compared to amalgam or a composite filling
- As mentioned earlier they are cemented to prepared natural tooth.This can increase the retention of the filling and longetivity. Hence preferred in large cavities that usually cannot be restored by direct conventional filling
- Highy aesthetic
- High Strength
Disadvantage:
- The disadvantage to onlays and inlays are just that it is technique sensitive ,requires two visits and cost.
- Eventhough cost is high it could be easily a one time filling rather that composite and amalgam direct restorations
Also two visit can be tedious but it only takes less chairside time and this disadvantage can be overruled by CAD-CAM which just takes a single sitting.
