What are the differences between inlays and onlays?

The difference between them is the area they cover. An inlay is more similar to a filling, but between the tubercles on the chewing surface of teeth. An onlay is done to cover one or more tubercles.

What does it contain?

An inlay or onlay is made out of ceramic or fiber-reinforced composite. The appropriate material is selected based on the material of the adjacent tooth, i.e., a natural, composite or porcelain tooth.

Why is it preferred?

In general, for the root canal treated tooth or severely decayed teeth, the decayed portion is cleared, as a result insufficient healthy tooth tissue is left. This makes impossible to contact with the adjacent teeth. If there is no contact point with the adjacent tooth, the food you consume is easily deposited in between and causes problems for the dental tissue and gums. The inlay or onlay is prepared on the mock-up, therefore the desired anatomic form and contact are achieved easily. In addition, it is more resistant to wear and chewing pressure that conventional filling material.

What is the life of an inlay or onlay?

The life of an inlay or onlay depends on the material the inlay or onlay is made, the condition of tooth treated with inlay or onlay, the chewing forces, oral hygiene of the patient, and regular visits to dentist. An inlay or onlay usually functions healthily for decades.

How is the procedure?

An inlay or onlay is prepared in the laboratory, therefore the procedure can be completed in two visits. The left of the healthy dental structure allows dentist to decide on whether it will be an inlay or onlay.

On the first visit, the decayed portion is removed and a dental impression is taken for the prepared tooth and surrounding teeth. The tooth is covered with a temporary filling material. The dental impression is forwarded to the laboratory. The temporary filling is removed on the second visit. The tooth is worn to check whether it fits in place, and transferred to the laboratory for polishing. At the same time, the tooth is cleaned. The inlay or onlay is cemented onto the tooth using a special adhesive. The closure is precisely adjusted by the dentist and the tooth is polished.

What to do after treatment

2 hours are required for the cement to cure. During 2 hours, you may drink anything but you should not eat anything.
