Contraindications to providing Onlays and Inlays include plaque and active caries. Whereas an onlay will involve one or more cusps being covered.

The Journal of Prosthetic Dentistry. From Wikipedia, the free encyclopedia. Luting cements can have a low modulus or a high modulus. There onlag no obvious contrast between the two.

It can also be used if there is minimal contour of remaining coronal tooth tissue with little retention. This may be caused by plaque retentive features of the restoration, or if the restoration is poorly bonded to the tooth. 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. A high-speed tapered diamond bur has the most convenient shape to prepare the buccal, lingual and proximal reduction of the tooth.

When an inlay is used, the tooth-to-restoration margin may be finished and polished to a very fine line of contact to minimize recurrent decay. Resin composite is widely used in dentistry as a direct and indirect restorative material.

The sub-structure is porous and therefore allows infiltration of the glass powder when fired again. The preparation of inlays and onlays mainly follows the same basic concepts of indirect restorations.

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. Sometimes, a tooth is planned to be restored with an intracoronal restorationbut the decay or fracture is so extensive that a direct restorationsuch as amalgam or compositewould compromise the structural integrity of the restored tooth or provide substandard opposition to occlusal i.


Bonding agents can be applied to dentine before cementation of inlays and onlays.

Once the wax pattern is constructed the fabrication of inlqy into the final restoration can begin, a method known as the Lost Wax Technique [27] is used. Although improvements of the composite resins could be achieved in the last years, solid inlays do exclude this problem. In such situations, an indirect gold or porcelain inlay restoration may be indicated.

Patients need to be able to cope with dental impressions as inllay are required for the fabrication of the indirect restoration.

If all cusps and the entire surface of the tooth is covered this is then known as a crown. Young children may be unable to cope with invasive dental treatment and long procedures, therefor it is advantageous to wait until they are fully cooperative. The onlay allows for conservation of tooth j when the only alternative is to totally eliminate cusps and perimeter walls for restoration with a crown.

Once confirmed, the milling process can begin.

Inlays and onlays

What’s the difference and which is the right one for you? Oxford, London, Edinburgh, Melbourne: In dentistry, inlays and onlays are a form of indirect restoration.

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. 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.

Reducing the patients risk of further disease infrustaciones to treatment provides predictable results and helps prevent further restorative procedures. This technique is only applicable when composite is used as the restorative material. The preparation of opposing cavity walls should be cut in a way to avoid undercuts in order to gain optimum retention from the cavity shape for the indirect restoration.


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. Incrustaicones is the buccal cusp for mandibular teeth and the palatal cusp for maxillary teeth. Ceramic offers a more aesthetically pleasing restoration colour than previous gold and amalgam restorations.

Metal-ceramic inlays were developed to see if the aesthetic advantages of an all-ceramic inlay restoration could incruustaciones replicated, whilst improving the strength and stability of the restoration. 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.

Development of digital impression systems including Lava Chairside oral scanner by 3M, Sirona’s CEREC and Cadent iTero System could help patients receive treatment if the contraindication is being unable to withstand conventional impressions.

Incrustaciones Inlay – Onlay

Opposed to this, direct composite filling pastes shrink a few percent in volume incrusttaciones hardening. The restoration is firstly removed and then the cavity can be converted by ensuring any undercuts are eliminated from the preparation. Once cast a layer of oxides are present on the surface, these can be removed by placing the restoration in an ultrasonic bath for 10 minutes.
