This technique involves placing a soft or malleable filling into the prepared tooth and building up the tooth. The material is then set hard and the tooth is restored. Where a wall of the tooth is missing and needs to be rebuilt, a matrix should be used before placing the material to recreate the shape of the tooth, so it is cleaned and to prevent the teeth from sticking together. Sectional matrices are generally preferred to circumferential matrices when placing composite restorations in that they favour the formation of a contact point. This is important to reduce patient complaints of food impaction between the teeth.
The advantage of direct restorations is that they are usually set quickly and can be placed in a single procedure. A decision is usually made based on the location and severity of the associated cavity.
An indirect restoration fabricated on a model, ready to be cemented on a natural tooth structure. In this technique, the restoration is fabricated outside of the mouth using the dental impressions of the prepared tooth. Common indirect restorations are done using gold or ceramics. While the indirect restoration is being prepared, a provisory/temporary restoration is sometimes used to cover the prepared tooth to help maintain the surrounding dental tissues.
