Tooth decay is treated with a method called filling. Fillings are done directly orally when the patient comes to the clinic. The advantage of this method is that it does not waste time and most of the time the process is completed in a single session. In some cases, the fillings are made outside the mouth and when the patient comes to the clinic, they are glued and better results are obtained. This form of treatment is called onlay-inlay.

The onlay begins with cleaning and measuring the patient's decayed tooth. The cleaned decayed tooth is temporarily filled with an easily removable filling material. The mold of the decayed tooth is taken from the measurement taken and the filling shape is created by using this mold by the technician.

composite, porcelain or gold. Which material to use is decided by evaluating factors such as the size of the caries, its appearance in the mouth, and the location of the filling. After the onlay is produced, the patient is given an appointment and the restoration is adhered.

The advantage of this form of treatment is that it can be studied in a much more detailed and efficient way during the production of the restoration in the laboratory environment compared to the oral environment. In this way, restoration margins are much nicer and edge leaks are reduced. The negative effects of factors such as moisture, saliva and blood, which are exposed during filling in the mouth, on the adhesion and hardening of the filling are also minimized.
