Inlays /onlays have the advantage of being less destructive than the crowns, whilst being stronger than composite resin fillings and retaining the natural color. Ceramic inlays/onlays are the ideal restorative material to replace old amalgam restorations.
The placement procedure typically requires two visits. On the first visit, the tooth will be prepared and then an impression of the tooth will be sent to the dental laboratory to create the permanent inlay or onlay. You will be given a temporary inlay or onlay to protect the tooth in the meantime. At the next visit, the temporary inlay/onlay is removed and the permanent one is cemented in its place. The bite is checked and the restoration is polished.
