Onlay-Technique - What is an onlay?
An onlay is a special type of tooth replacement.
As opposed to when an inlay is inserted and not the whole chewing surface is covered, here in most cases, the whole chewing surface and also parts of the sides of the cusps are covered with metal and ceramics. This means that an onlay is inserted when the tooth for an inlay is already too damaged and the cusps of the tooth also need to be treated.
Which materials are used for an onlay?
An onlay might be made of different materials:
Ceramics belongs to the most beloved materials as it can be fitted perfectly to the natural colour of your teeth and as a result of that it is practically invisible in the mouth.
- Ceramics is body-compatible and does not cause allergies.
- It does not cause any sensitivity to temperature.
- Unlike with supplies containing metal, here you will not experience metallic taste.
- Ceramics does not alter in colour in time.
- Ceramics arises only after a really long time.
Golden has the advantage of being a material used for the longest time in the history of tooth medicine. As we have long-term experience and proof we can say that golden the load in the mouth endures. Typical time of wearing is usually 15 years or more.
- The abrasion of an onlay is similar to the natural abrasion of the teeth.
- Golden does not oxidize and causes no colouring.
- Only a small amount of people have allergic reactions to golden.
An onlay is able to help you to save an already highly damaged tooth. A cavity is always really difficult to treat because neighbouring healthy teeth often need to be grinded. If a crown is put on the teeth, it means that also healthy parts of the teeth have to be grinded.
As a result of all these, an onlay is a really adequate opportunity of tooth replacement and allows the dentist to save as much of the healthy part of your tooth as possible.
Depending on how many sides of the tooth are affected, the fillings will differ in the following:
- single surface fillings: only the chewing surface of the tooth is affected.
- double surface fillings: the chewing surface of the tooth and the surface of a side with a neighbouring tooth, on the left or on the right, are affected.
- triple surface fillings: the chewing surface of the tooth and the surface of two sides with a neighbouring tooth, on the left and on the right, are affected.
If a bigger part of the tooth substance is to be replaced, respectively cusps of the tooth are also affected, we speak about a partial crown or an onlay.
When nursing is appropriate, these types of replacements are highly endurable. They may last even up to two decades. They can be made of:
Golden inlays have proved themselves to be especially endurable. Stiffness as well as form retention is excellent. The transition between metal and tooth can be created without any gaps. Golden inlay can be worked off really thin. This is the reason why in the case of golden inlays, as opposed to tooth-coloured, ceramic or composite inlays, a lot less substance of the tooth needs to be done away with. As this is not considered as aesthetic in the frontal area, patients prefer ceramic inlays in this region.
