Inlay and Onlay (Ceramic Fillings)

Inlay and Onlay (Ceramic Fillings)

Ceramic fillings are a kind of partial porcelain that restores the loss of substance in the teeth due to factors such as caries, root canal treatment or trauma in a way that only completes the missing parts of the tooth, or simply a type of filling made of composite or porcelain strengthened in the laboratory. Compared to composite fillings, they are much more compatible with the tooth to which they are applied and adjacent teeth.

Ceramic inlays and onlays, just like lamina veneers, preserve the intact part of the tooth in its natural shape. Such fillings are preferred over metallic and dark colored amalgam fillings in the posterior teeth of patients who have aesthetic and comfort expectations.

Apart from this, in cases where a large number of fillings are required, after the tooth preparation and measurement stage in a single session, the ceramic fillings to be prepared in the laboratory are placed in the second session, thus saving a lot of time. Since the fillings prepared in this way are not prepared in the mouth as in the classical fillings, they are perfectly compatible with the teeth thanks to their preparation in the laboratory.

The cure life of ceramic fillings is longer than composite fillings. Since the porcelain filling has the same hardness as the tooth, it prevents fractures caused by the bite force and contributes to the health of the tooth as it used to be. In addition, because it is prepared in tooth color, ceramic fillings look so natural that they cannot be distinguished from the outside with the naked eye.

Ceramic fillings are a filling method developed to protect the healthy tooth tissue in cases where there is too much material loss in the tooth and the tooth needs to be reduced and crown application. Since its appearance is more aesthetic and more useful, it is preferred fillings instead of amalgam fillings.

These fillings, which have a natural appearance that cannot be distinguished with the naked eye, have a structure that prevents discoloration caused by cigarettes or other dyeing substances that may occur over time, thanks to improved polishing techniques. People can move freely as if there is no filling in their teeth, and they can have healthy and aesthetic teeth for many years.

How is Ceramic Filling Made?

First, the person's tooth is cleaned of all caries. Then, the concave areas, that is, the areas that restrict the lines that may prevent the measurement and the production of the porcelain piece, are arranged by supporting them with appropriate porcelain fillers. The precise measurement of the tooth to be filled with porcelain filling is taken and sent to the laboratory. Then, the cavity of the tooth to be filled with ceramic filling is closed with a temporary filling material. The precision measurement in the laboratory is prepared by the technician by pouring it with the help of sensitive plaster material. In the model, which is prepared according to the size taken by the doctor, the missing parts are completed with appropriate wax modeling so that all kinds of anatomical forms of the porcelain filled tooth are completed. By using the wax package, the ceramic inlay or onlay material is obtained in a laboratory environment to complete the missing tooth form. In order to ensure the perfect compatibility of this material with the tooth, the porcelain piece is corrected on the mold according to the reference plaster model by an experienced dental technician. The inlay or onlay filling piece prepared by the technician is sent to the doctor and rehearsed in the mouth with the ready porcelain process. If the porcelain fully adapts, it is adapted by the doctor with the adhesive system and integrated with the tooth. Polishing and polishing is applied on the filling. In this way, the treatment is terminated.


What are the advantages of ceramic fillings?

  1.  Ceramic inlay onlay filler consists of pressed porcelain. This material is more durable than fillers with composite content.
  2. For ceramic inlay onlay fillings aesthetic and is long lasting. They are biologically compatible and cannot cause an allergic reaction. In addition, tooth restoration compliance is very sensitive.
  3. None of the wear and deformation problems that occur in composite fillings in the middle and late periods are experienced in ceramic inlay onlay fillings.
  4. The ceramic inlay onlay filling, which is prepared in harmony with the tooth structure, does not cause marginal edge leakage in the future, as in the composite filling. These problems are definitely not experienced in ceramic inlay onlay fillings.
  5. The interface between the chewing surface and the ceramic inlay onlay fillings is quite well polished. Therefore, it does not hold bacteria and does not allow the formation of stains.
  6. Due to the preparation of ceramic inlay and onlay fillings in the laboratory, they imitate the missing contours of the tooth and the contact areas with neighboring teeth anatomically, almost perfectly. For this reason, it prevents the accumulation of food residues between the teeth, and therefore, problems that may arise are not experienced. Due to these effects, people feel very comfortable. During the consumption of hard foods such as meat, there is no problem with porcelain inlay onlay fillings.
  7. Since the chewing surfaces of ceramic inlay onlay fillings are exactly the same as the anatomical chewing line of the tooth, they have much more superior properties than composite fillings during chewing and grinding actions.
  8. The ceramic inlay onlay filling, which is compatible with the teeth in every aspect, does not cause leakage in the teeth and does not cause deformation problems even after 15-20 years.
  9. Ceramic inlay and onlay fillings are in good harmony with the weak tissue that remains intact in the tooth, ensuring that natural structures remain healthy for many years.
  10. Because they establish a one-to-one and stress-free relationship with the tooth, porcelain fillings prevent cracks and fractures that may occur in weak areas of the teeth.
  11. Porcelain inlay onlay fillings are the closest and most suitable for the hardness of the tooth. with the gum It is the most compatible material. Since the hardness of the filling is very close to the enamel tissue of the tooth, it does not abrade the teeth and does not show wear properties like composite fillings. When there is a large loss of material in the tooth, these should be preferred instead of crowns or composite fillings.

What are the Disadvantages of Ceramic Fillings?

The biggest disadvantage of these fillings is that they are a little more costly than composite fillings. The cost of ceramic inlay onlay fillings is approximately 3-4 times higher than composite fillings for patients. These fillings require very sensitive work. If they are not done properly, they will not provide the same fit as the tooth.
