Dental inlays and Onlays are single-fit, solid pieces of material - that are cemented on teeth to cover damages. Inlays are usually cemented on the chewing surface, without covering the cusps. Onlays, on the other hand, can cover one or more cusps.
When it comes to advanced tooth filling procedures, you have an option between direct restoration and indirect restoration. A direct restoration is a basic filling procedure. It involves building up the tooth directly inside the mouth using a soft/malleable material such as glass ionomer or resin composite. Indirect restoration like Inlays and Onlays involves preparing the filling material outside, based on individual tooth impressions - as taken by the dentist or scanned by a machine. The Inlays and Onlays are then cemented on each tooth.
In case a machine is not used, it usually takes two separate visits to get the job done; the dentist takes the impression of the tooth during the first appointment then sends it to the lab for use in preparing the inlays and Onlays.
What materials are used for inlays and Onlays?
Inlays and Onlays can be done using either ceramics or gold. They are prepared outside the mouth in special dental labs. The treatment is usually done on molars or premolars that have sustained too much damage that a basic filling won't work to treat. The dentist will drill the cavity - then place the inlay or onlay.
Onlays and Inlays are used in the case tat the decay/fracture is even more extensive than meets the eye.
Inlays and Onlays are stronger and more durable than basic fillings. But inlays and onlays don't come cheap. They are made in special dental laboratories, so they cost more. Inlays and onlays may also be more difficult to repair – when compared to direct fillings. Then there is the matter of dental insurance; most dental insurance providers rarely cover Inlays and Onlays procedures.
Still, Inlays and Onlays are the best tooth restoration procedure aesthetically-speaking. Inlays and Onlays, especially those made from ceramics, are hard to notice as they are of the same color as the rest of the tooth!
