Incrustaciones by Alfonso Ibarra on Prezi

In the majority of clinical situations an inlay preparation is being made from ibcrustaciones tooth that already has a Class II restoration and is being prepared to protect the tooth. Inlay wax is chosen due to its brittleness — it breaks upon removal from undercut of a cavity, either on the die or in the mouth.

This removes the oxides along with any remnants of investment material. According to a year evaluation of ceramic inlays cemented with both chemically cured resin composite and dual cured resin composite; the inlays cemented with chemically cured survived longer after cementation.

Int J Comput Dent. Casting methods include the use of steam lncrustaciones or a centrifugal system.

Then, a composite restoration is built up directly on the preparation, allowing it to take the shape of the cavity. When preparing a cavity to retain an indirect restoration we risk damage to the nerve supply of a vital tooth. 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.

If a tooth has extensive caries or tooth surface loss which would provide difficulty bonding an inlay or onlay then it might be more inay to consider a full coverage extra coronal restoration. There are no obvious contrast between the two. This method is only applicable to sintered alumina core porcelain.


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, icrustaciones of fabrication, marginal integrity, proper contouring for gingival tissue health, and ease of cleansing offers. The restoration itself does not alter the risk, which allows subsequent caries to develop around the indirect restoration placed.

The aim of tooth preparation is to preserve more tooth tissue compared to a crown preparation, while giving an adequate amount of protection to the tooth. 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.

Biologic width Centric relation Crown-to-root ratio Maximum intercuspation Occlusion vertical dimension mutually protected Dahl concept Masticatory force Neutral zone.

Due to the more in-depth curing method, using heat, pressure or strong light, this can have a lower polymerisation shrinkage. Inlays are usually indicated in,ay there has been repeated breach in the integrity of a direct filling as metal inlays are more superior in strength.

Onlays are indicated when there is a need to protect weakened tooth structure without additional removal of tooth tissue unlike a crown, e. However, for indirect restorations using gold then the preparation shape must have parallel walls as most the retention is gained from the cavity shape. This is because conventional ceramics have a higher fracture risk and fractures can propagate easily under cyclical loading causing marginal ridge or bulk fracture.

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.

The wax is embedded into an investment material with a sprue former — this forms a passage for molten metal to be poured through into the cylinder. Next, the restoration can be designed, by the software programme, on the virtual casts. To ensure longevity it is beneficial to avoid heavy occlusal forces. Resin composite is widely used in dentistry as a direct and indirect restorative material. For technique 1, a wax pattern is designed on the die from the cast impressions incrustacines for technique 2 the wax is packed into the tooth preparation in the mouth and adapted the shape of the cavity.


Inlays and onlays

Alumina core porcelain [22]. The preparation of opposing cavity walls should be cut in a way to avoid undercuts in order to gain optimum retention from the incrustaciohes shape for the indirect restoration. In this case, this is a beneficial character as it helps us to identify the presence of an undercut which then can be removed.

The process of preparation and cementation of an inlay or onlay is usually carried out over two appointments, with the preparation being carried out during the first appointment and cementation at the second. This is an alternative to a direct restorationmade out of composite, amalgam or glass ionomerthat is built up within the mouth.

Incrustaciones Inlay y onlay en los distinto by MIGUEL ROJAS on Prezi

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. There are a few methods of fabricating inlays and onlays, depending on the restorative material used. Composite inlays are cured by polymerisation shrinkage.
