The restoration itself does not alter the risk, which allows subsequent caries to develop around incrutsaciones indirect restoration placed. The preparation of inlays and onlays mainly follows the same basic concepts of indirect restorations.
Ceramic inlays can also be cured with chemically cured resin composite or dual cured resin composite. Indirect restorations are contraindicated in patients under 16 as the pulp inccrustaciones is still large and wide dentinal tubules increase the stress on the pulp.
Inlays and onlays
The restoration is then light-cured in the tooth before being removed from the tooth to be further light-cured. Inlay wax is chosen due to its brittleness — it breaks upon removal from undercut of a cavity, either inrcustaciones the die or in the mouth. This property allows gold to be used in thinner cross sections, meaning less tooth tissue needs to be removed during tooth preparation compared to other restorative materials, to achieve the same strength.

Ceramic offers a more aesthetically pleasing restoration colour than previous gold and amalgam restorations. A high-speed tapered diamond bur has the most convenient shape to prepare the buccal, lingual and proximal reduction of the tooth. The best instrument to use for this is a high-speed diamond fissure bur and the reduction should follow the inclination of the cusps and grooves as this will allow the preservation of more tooth tissue.
Prior to cementation of the restoration onto the prepared the tooth, the layer of separating materials needs to be removed to ensure effective bonding between the tooth and the restoration.
Just as inlays, onlays are fabricated outside of the mouth and are typically made out of gold or porcelain. Applied dental materials incrustackones ed. Once confirmed, the milling process can begin.
An inlay will incorporate the pits and fissures of a tooth, mainly encompassing the chewing surface between the cusps. High failure rates were associated with teeth that had previous root canal treatmentand with patients who exhibit para-functional habits such as bruxismor teeth clenching.
This means they are made outside of the mouth as a single, solid piece, that fits the specific size and shape of the cavity. By using this technique, an impression of the tooth preparation is not required.
Onlays are indicated when there is a need to protect weakened tooth structure without additional removal of tooth tissue unlike a crown, onlaay. The onlay allows for conservation of tooth structure when the only alternative is to inlat eliminate cusps and perimeter walls for restoration with a crown.
However, using this indirect laboratory method demands more skill and time, and is more destructive as tooth preparation is needed prior to taking an impression.

In other projects Wikimedia Commons. In such situations, an indirect gold or porcelain inlay restoration may be indicated. Once cast a layer of oxides incrustcaiones present on the surface, these can be removed by placing the restoration in an ultrasonic bath for 10 minutes. It is possible for these indirect restorations to be provided in one visit. Bonding agents can be applied to dentine before cementation of inlays and onlays.

Incrustaciones Inlay – Onlay
It is important to ensure adequate oral hygiene before providing any indirect restoration as failure to manage the caries risk of an individual may result in recurrent caries. In more recent years, inlays and onlays have been made out of ceramic materials. When preparing a cavity to retain an indirect restoration we risk damage to the nerve supply of a vital tooth. However, the disadvantage of super curing is that it leaves less reactive resin groups to bond to the cement and incrustafiones the strength of bond will be less.
