Porcelain inlay

When is it advised to prepare an inlay / onlay?
In case of the decay of molars, it often happens that the teeth are considerably damaged, or more than half of a tooth is broken because of a deep carious cavity. Usually some food remains between two teeth and the cavity starts from here. Because it is in a hidden place, the toothbrush does not reach it, so the caries protrudes sneakingly towards he center of the tooth, while nothing is visible from the surface, since the tooth seems to be perfectly healthy. Finally, when the caries destroys a large amount of the tooth, the surface cannot hold either, the tooth breaks in and the huge cavity becomes visible.
When such a huge part of the coronal element is destroyed, it is not advised and not possible to make a simple filling.
- It is very difficult to fix a simple filling in such a big cavity, it can fall out easily
- When preparing a filling, a large amount of filling material may shrink when illuminated, so the border closure of the filling might be damaged, which might cause secondary caries in the long run
- The remained intact surfaces cannot be protected by a simple filling, a more serious restoration is needed
When half of the tooth is missing, why is inlay better than filling?

- It can be securely fixed
- Protects the remaining intact tooth tissues
- The chance of a secondary caries is smaller, with sufficient dental hygiene
- Perfectly aesthetic – the technician forms the tips and fissures with artistic quality
- The original form and contour of the tooth can be perfectly restored
- The contact spot system (touching the adjacent teeth) can be established more precisely than in the case of a filling
