Filling is applied in the loss of material in the teeth. Inlay / Onlay restorations are aesthetic fillings prepared in the laboratory for the restoration of teeth that require large fillings or have had root canal treatment.


Inlays or onlays are used in canal treated or severely decayed teeth, where there is not enough tooth structure to support the filling and the tooth is not damaged enough to be covered with a crown. Inlay – onlay fillings are preferred because they cause very little material loss in the tooth during the construction phase. It can be applied to patients who are allergic to normal fillings. It is preferred in the treatment of large material losses where it is inconvenient to make composite restorations.
After the decayed teeth that need filling are cleaned, a digital impression is taken with an intraoral scanner and the filling model is designed in digital environment and produced by CAD-CAM production methods as porcelain or composite and applied to the patient’s mouth.
  • Compared to other coating treatments, material loss is less in inlay-onlays.
  • They protect healthy tooth tissue.
  • It is more resistant to chewing and biting forces.
  • It is more resistant to abrasion or breakage.
  • The fill color is self-protective and aesthetic.
  • Since a special bonding technique is used, it is aimed to avoid edge leakage.
  • Does not show allergic reactions.
  • The treatment life is longer than composite fillings.
Treatment process, outcome and planning may differ for everyone. Generally, the inlay-onlay filling treatment process can be specified as a single session and 30 minutes for a tooth.
The duration of use of Inlay – Onlay filling treatment is directly proportional to the person’s attention to his own oral care and hygiene. If the person maintains oral hygiene regularly and does not disrupt the dentist’s control, the use of fillings is provided for many years. However, in cases where oral hygiene is not good, leakage may occur between the porcelain and natural teeth and caries may occur in the natural teeth. After the treatment, regular control, brushing and flossing are sufficient.
