Incrustaciones Inlay – Onlay

However, these systems incgustaciones not widely available in dental practices, as of Views Read Edit View history. Composite inlays and onlays offer great aesthetics, as a combination of different shades and opacities can be used in a layering technique, equalling or surpassing the aesthetically pleasing all-ceramic restoration.

It comes in different compositions, variable in content and size of filler particles.

In dentistry, inlays and onlays are a form of indirect restoration. Inlays and onlays are used in molars or premolars, when the tooth has experienced too much damage to support a basic filling, but not so much damage that a crown is necessary. Alumina core porcelain [22]. Once the wax pattern is constructed the fabrication of this into the final restoration can begin, a method known as the Lost Wax Technique [27] is used. Indirect restorations are contraindicated in patients under 16 as the pulp chamber is still large and wide dentinal tubules increase the stress on the pulp.

This method is only applicable to sintered alumina core porcelain. What’s the difference and which is the right one for you? This reduces flexure under loading and prevents crack formation.

Gold has many advantages as a restorative material, including high strength and ductility, making it ideal to withstand the masticatory forces put upon the teeth.


A study showed that the fracture resistance of all-ceramic inlays was greater than that of these metal-ceramic inlays. A return visit is then required to fit the final prosthesis.

In other projects Wikimedia Commons. Luting cements can have a low modulus or a high modulus. This page was last edited on 24 Decemberat CS1 French-language sources fr CS1 maint: This may be caused by plaque retentive features of the restoration, or if the restoration is poorly bonded to the tooth. This technique is only applicable when composite is used as the restorative material.

There are two ways this can be done, either by blocking the undercuts out with an adhesive restorative material or by removing tooth tissue to create the divergent cavity needed. Inlays are usually indicated when there has been repeated breach in the integrity of a direct filling as metal inlays are more superior in strength. Patients need to be able to cope with dental impressions as these are required for the fabrication of the indirect restoration.

Inlay wax is chosen due to its brittleness — it breaks upon removal from undercut of incrhstaciones cavity, either on the die or in the mouth. In more recent years, inlays and onlays have been made out of ceramic materials. The onlay allows for conservation of tooth structure when the only alternative is to totally eliminate cusps and perimeter walls for inay with a crown.

Whereas an onlay will involve one iinlay more cusps being covered. Applied dental materials 9th ed. Direct restorations, for example composite may be beneficial when restorations are small. The preparation of inlays and onlays mainly follows the same incrustacines concepts of indirect restorations. The model is scanned and the 3D image is uploaded onto the software. 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.

Occlusal forces are greater on molars when compared to premolars. This is the buccal cusp for mandibular teeth and the palatal cusp for maxillary teeth. Int J Comput Dent. If the onlay or inlay is made in a dental laboratory, a temporary is fabricated while the restoration is custom-made for the patient.

Inlays and onlays

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. Compared to ceramic [34] and gold [35] inlays incrustacilnes onlays, composite can provide similar advantages, but a comparison of the longevity of composite is unknown.

Opposed to this, direct composite filling pastes incrustacilnes a few percent in volume during hardening. The key comparison between them is the amount and part of the tooth that they cover. If all cusps and the entire surface of the tooth is covered this is then known as a crown.

Metal-ceramic inlays were developed to see if the aesthetic advantages of an all-ceramic inlay restoration could be replicated, whilst improving the strength and stability of the restoration. Due to the more in-depth curing method, using heat, pressure or strong light, this can have a lower polymerisation shrinkage.
