Inlays and onlays are a solution between filling and crown (veneer). In cases where there is not enough tooth structure to support the filling and the tooth is not damaged enough to be covered with a crown, inlays or onlays are used.
Compared to inlays, onlays cover a larger area. Inlays are more similar to fillings, but they are located between the cusps (tubercles) on the chewing surfaces of the teeth. Onlays are made to cover one or more mounds.
Inlays and onlays are made of ceramics. The lifespan of an inlay or onlay depends on the material it is made of, the condition of the tooth it is on, chewing forces, how much attention the patient pays to oral hygiene and care, and regular dentist checks. They usually continue to function healthily for decades.
In Which Situations Are They Used?
A damaged tooth can be renewed with inlay or onlay. In cases where more than half of the chewing surface of the molar tooth is decayed, onlay is preferred instead of inlay.
How is the Application Done?
The tooth and surrounding tissues are anesthetized with local anesthesia. Since inlays and onlays are prepared in the laboratory, they can be completed in two
appointments. The remaining healthy tooth structure allows the dentist to decide whether to make inlays or onlays.
At the first appointment, the decay is cleaned and the prepared teeth and stage teeth are measured. The tooth is closed with a temporary filling material. The impression is sent to the laboratory.
The temporary filling is removed at the second appointment. The tooth is tested and sent to the laboratory for polishing. At the same
time, the tooth is cleaned. Inlays or onlays are bonded to the teeth using a special adhesive. The bite is fully adjusted and polished by the dentist
.
What should be done after the treatment?
For the care of inlays and onlays, only tooth brushing, flossing and regular dental work are done. Regular oral care, including visits to the physician
is required.
What are the risks?
If inlays and onlays come into contact with saliva while being bonded, they may not adhere completely. Porcelain inlays or
onlays can also break.
