Definition of An Onlay

website builder One or more of the cusps on a tooth are replaced by an onlay, a repair that is made externally. It is stuck in place with glue. It is a more conservative or tooth structure-saving procedure than a full crown. It might be made of porcelain or metal. Using a cerec machine, the restoration can be finished in our lab or at our office.


An onlay can cover a wider area, including the cusps, as opposed to just filling in the gaps there. Though they do not entirely cover the tooth’s surface, they function similarly to crowns. Despite being made of the same materials and carrying out the same function, they cover different tooth surfaces. This is in order to provide the best protection against tooth decay.

Inlay Versus Onlay

Inlays versus onlays describe what most people call a restoration that is not direct. This filling is inserted within the mouth, unlike the filling that finished instantly. They are a very efficient method of rebuilding your teeth and offer a number of advantages. This is particularly if a sizable portion of the tooth structure has been lost.

An inlay is a restorative that is affixed inside the tooth. An onlay replaces some or all of the cusps by being cemented on top of the tooth. The amount of rot present or the amount of existing infill that needs to be replaced will determine the shape and kind of restoration needed for your teeth. Therefore, restorations are typically constructed of a combination of the two restorations rather than an inlay or an onlay. Premolars and molars, which are the posterior, or back teeth, are often the only teeth that receive them.
