Inlays and onlays – Wikipedia

This means they are made outside of the mouth as a single, solid piece, that fits the specific size and shape of the cavity. Evidence Fuzzi and Rapelli has shown greater failure of Onlays and Inlays in molars than premolars over an 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 incristaciones and the restoration.

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. It can also be used if there is minimal contour of remaining coronal tooth tissue with little retention.

It went on further to find that it was the taper of the inlay oncrustaciones that affected the fracture resistance more so than the choice of restoration material.

In such situations, an indirect incrustacines or porcelain inlay restoration may be indicated.

While short term studies come to inconsistent conclusions, a respectable number of long-term studies detect no significantly lower failure rates of ceramic [4] or composite [5] inlays compared to composite direct fillings.

A systemic review found that the most common cause of onlay failure is ceramic fracture, followed by ceramic de-bonding from the tooth structure, and the occurrence of secondary caries which is seen as a discolouration at the margins of the restoration. An evaluation of different inlay fabrication methods”.

It can be easily repaired or modified as composite can bond to existing material. Views Read Edit View history. When decay or fracture incorporate areas of a tooth that make amalgam or composite restorations inadequate, such as cuspal fracture or remaining tooth structure that undermines perimeter walls of a tooth, an onlay might be indicated. Ceramic offers a more aesthetically pleasing restoration colour than previous gold and amalgam restorations.


Direct restorations, for example composite may be beneficial when restorations are small. Inlays and onlays made from ceramic or metal alloy require laboratory work and therefore can only be fabricated using indirect restorative techniques as mentioned in the previous section.

Casting methods include the use of steam pressure or a centrifugal system. However, these systems are not widely available in dental practices, as of If the onlay or inlay is made in a dental laboratory, a temporary is fabricated while the restoration is custom-made for the patient. What’s the difference and which is the right one for you?

Historically inlays and onlays will have been made from gold and this material is still commonly used today. There are no obvious contrast between the two.

Incrustaciones by Alfonso Ibarra on Prezi

While inlays might be ten times the price of direct restorations, it is often expected that inlays are superior in terms of resistance to occlusal forces, protection against recurrent decay, precision of fabrication, marginal integrity, proper contouring for gingival tissue health, and ease of cleansing offers. The aim of tooth preparation is to preserve more tooth tissue compared to a crown preparation, while giving incrustacionse adequate amount of protection to the tooth.

The use of gold as a restorative material for the production of inlays and onlays is fading due to the increase in usage of more aesthetically pleasing tooth coloured materials. This page was last edited on 24 Decemberat A functional occlusal bevel should be created on the occlusal loading cusp of molar teeth by holding the bur at a 45 o angle to the occlusal surface. Inlays and onlays are cemented in the mouth using adhesive resin luting cements.

Inlays and onlays

CS1 French-language sources fr CS1 maint: However, for indirect restorations using gold then the preparation shape must have parallel walls as most the retention is gained from the cavity shape. It comes in different compositions, variable in content and size of filler particles. Compared to incustaciones [34] and gold olnay inlays and onlays, composite can provide similar advantages, but a comparison of the longevity of composite is unknown. Opposed to this, direct composite filling pastes shrink a few percent in volume incrustacions hardening.


This method is only applicable to sintered alumina core porcelain. Preparation of inlays are with close to parallel walls and a key on the occlusal surface- this is sometimes sufficient for retention purposes so adhesive resin luting cements may not be needed.

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.

For tooth preparation, firstly start with occlusal reduction which depending on the restorative material being used can range from 0. If a tooth has extensive caries or tooth surface loss which would provide difficulty bonding an inlay or onlay then it might be more appropriate to consider a full coverage extra coronal restoration. Following sintering, the outer surface of the sub-structure is painted with lanthanum aluminosilicate glass powder. A return visit is then required to fit the final prosthesis.

Then, a composite restoration is built up directly on the preparation, allowing it to take the shape of the cavity. Whereas an onlay will involve one or more cusps being covered. Inlays require elimination of undercuts, therefore direct restorations may preserve tooth structure whilst also avoiding unwanted laboratory costs.

The key comparison between them is the amount and part of the tooth that they cover. 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 dentistry, inlays and onlays are a form of indirect restoration.

In recent years, newer types of porcelains have been developed that seem to rival the longevity of gold. Oxford, London, Edinburgh, Melbourne: However, in the main the subsequent caries around a restoration is because the caries risk has not been reduced. 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.

This can protect remaining tooth structure.
