Onlay Filling

Inlay and Onlay – Ceramic Filling

Inley and Onley ceramic filling application, which is among the modern dental treatment options, is a type of filling between standard filling treatments and full crowns. Inlay and Onlay ceramic filling is the most suitable treatment method for teeth that do not require full crown application but are too damaged to be filled with conventional filling methods. Inley and Onlay are made of ceramic, fiber-reinforced composite. In case the teeth in contact are porcelain, suitable material can also be preferred.

Differences Between Inlay and Onlay

Inlay and Onlay ceramic fillings differ in terms of the area they cover. Onlay ceramic filling application is applied on large tooth surfaces, while inlay ceramic filling is applied on relatively smaller areas. Inlay fillings are located between the stigmas on the chewing surface of the teeth. Onlay ceramic fillings are made to cover one or more mounds. There is not enough dental tissue in teeth that have undergone root canal treatment or in severely decayed teeth. Since there is not much tissue to come into contact with the surrounding teeth, the food eaten causes accumulation between the teeth. However, since the Inlay and Onlay ceramics studied on the model in the laboratory environment are designed to form contact with the surrounding teeth, a more durable coating emerges compared to the classical filling material.

What are the Advantages of Inlay and Onlay Ceramic Coatings?

Inlay and Onlay fillings are aesthetic and long-lasting. Ceramic fillings are more durable than fillings with composite content. They are biologically compatible and do not cause an allergic reaction. None of the wear and deformation problems that occur in composite fillings in the middle and late periods are experienced in ceramic inlay and onlay fillings. Ceramic fillings, which are prepared in harmony with the tooth structure, do not cause edge leaks in the future like standard fillings. Since the coating is highly polished, it does not cause bacteria formation. Ceramic Inlay and Onlay fillings allow for many years of use by adapting to the weak tissue that remains intact in the tooth.

How Long Does Inlay and Onlay Ceramic Coating Last?

Inlay and Onlay ceramic filling is performed in two different stages, before and after the filling application. The dentist decides on the type of Inlay or Onlay filling that the patient needs at the first examination. If the tooth is decayed, it is cleaned. The tooth is prepared if it has had root canal treatment before. The measurement is taken. The tooth to be filled with ceramic filling is filled with temporary filling material. At that time, ceramic Inlay or Onlay tooth coating is made ready in the laboratory environment. The ceramic tooth, which is ready in the second session, is rehearsed in the mouth. If everything goes as planned, the ceramic filling is integrated with the adhesive system by the dentist and its integration with the surrounding teeth is ensured. As the final application, polishing and polishing is applied on the filling.
