INLAY/ONLAY RESTORATİONS

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 and onlays are made of porcelain or fiber reinforced composite material. The choice of material to be used is determined by whether the other teeth in contact are natural, composite or porcelain.

Why Prefer Inlay / Onlay Restorations?

The most important reason for preference is that it requires less material loss in the tooth during the construction phase. Only the decayed tissue of the tooth is cleaned and then the tooth is measured. Then, porcelain or composite inlay / onlay fillings prepared in the laboratory are adhered to the teeth with adhesive systems. This method has many advantages in terms of dental and gingival health.

What are the Advantages of Inlay / Onlay Restorations?

They are aesthetic, Since inlay and onlay restorations can be made using porcelain and composite materials, they look so natural that they cannot be distinguished from our own teeth in terms of tooth color. They are long-lived, With this method, after cleaning the caries in the teeth, the molds of the teeth (with digital or paste-like material) are taken and a dental model is obtained in the laboratory. Filling is made from porcelain or composite material on this model. Application of fillings outside the mouth provides the advantage of being processed in more detail. When the composite material applied outside the mouth is applied in this form, there is less polymerization shrinkage and more durability. This filling, which is performed outside the mouth, is adhered to the cavities where caries are cleaned with adhesive systems. It is also more resistant to abrasions and chewing pressures than conventional filling material. It also prevents breakage caused by the bite force. They protect the remaining intact tooth tissue,Inlay / onlay (porcelain or composite filling prepared in the laboratory) is applied especially on the teeth undergoing root canal treatment or on tooth surfaces with advanced caries. After cleaning the caries in these teeth, insufficient healthy tooth tissue remains. This makes contact with neighboring teeth impossible. If there is no contact point with the neighboring tooth, the food you eat easily accumulates in between, which causes problems in the dental tissue and gums. Since inlay and onlay fillings are prepared on the model, the desired anatomical form and contact are easily achieved. In this way, dental and gingival health is preserved after the treatment.The risk of edge leakage and new caries formation is minimal, The advantage of this form of treatment is that the restoration can be studied in a much more detailed and efficient manner during its production in the laboratory environment compared to the oral environment. In this way, the restoration margins are much more beautiful and edge leakage is reduced. The negative effects of factors such as moisture, saliva and blood, which are exposed during the filling in the mouth, on the adhesion and hardening of the filling are also minimized. This ensures that the teeth are as healthy as before. Tooth-restoration compatibility is very sensitive, The goal of dentistry is to preserve as much of your natural tooth structure as possible. For this reason, your dentist may recommend inlays and onlays instead of crowns in cases where teeth can be restored with a more conservative treatment method.

How Long Do Inlay and Onlay Restorations Live?

The life of inlay or onlay restorations depends on the material, the condition of the tooth, chewing forces, how much attention the patient pays to oral hygiene and regular dental check-ups. They usually continue their duties in a healthy way for decades.

How to Apply in Inlay / Onlay Restorations?

● Since inlays and onlays are prepared in the laboratory, they can be completed in two appointments.

● At the first appointment, the caries is cleaned and the prepared tooth and surrounding teeth (with digital or paste-like impression material) are measured. The dental cavity is closed with a temporary filling material. The measurement is sent to the laboratory.

● Temporary filling is removed in the second appointment. The inlay / onlay coming from the laboratory is rehearsed. The tooth is prepared for the bondingprocess. The inlay or onlay is adhered to the tooth using a special adhesive. The closure is precisely adjusted and polished by the dentist.

What is the Difference Between Inlay and Onlay?

The difference between them is in the area they cover. Inlays are more like fillings, but they are located between the cusps (tubercles) on the chewing surface of the teeth. Onlay, on the other hand, is made to cover one or more mounds.
