Inlays, Onlays and Overlays

Inlays are similar to fillings but the entire work lies within the cusps (bumps) on the chewing surface of the tooth. Onlays are more extensive than inlays, covering one or more cusps. Onlays are sometimes called partial crowns. Overlays extends outwards from onlays.
 
Inlays, onlays and overlays are normally done to repair damaged portion of teeth that may be too large to be fixed with composite resin fillings whilst the damage is not overly extensive requiring a dental crown.
 
There are basically 3 dental restorations to repair damaged teeth or tooth decay:
  1. Dental Fillings
  2. Inlays and Onlays
  3. Overlays or Dental Crowns

  2. Possiblility of “galvanic shock” if both gold and amalgam fillings are right next to each other

Ceramic Onlays

ceramic inlays

Advantage

Conclusion – Inlays, Onlays and Overlays

Inlays are onlays are pre-fabricated fillings pieces used to fill damaged portions of teeth. They may be made from gold, porcelain or glass. 

Onlays and inlays are restorative treatments normally treated by an operative dentist, restorative dentist, cosmetic dentist or prosthodontist. Porcelain based inlays and onlays are commonly opted for their aesthetics and strength. As inlays and onlays do not extend outwards over teeth, they can sometime dislodge but can be easily bonded back. If the tooth damage is large or for better overall retention, a dental crown may be recommended.
