DENTAL INLAYS AND ONLAYS
Inlays and onlays are highly custom, lab made restorations that are typically fabricated out of ceramic, metal, or gold.
When repairing a small cavity, an inlay can restore the tooth in a more durable manner than a traditional filling.
An onlay on the other hand, is used to rebuild a tooth that has damage to one or more cusps. This treatment helps to restore optimal shape and function while saving as much of the natural tooth as possible.
The procedure involves removal of all decayed tooth structure and taking a final impression of the prepared tooth. The tooth is temporized while the permanent restoration is being made at the lab. When the permanent restoration is ready, it is fitted in the mouth and cemented after the fit is optimized.
The following videos from Spear Education show visual presentations of how these procedures are performed.
