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. The container, or casting cylinder, is then placed in a furnace to burn out the wax and what is left is a hollow shape ready for molten metal to be poured into.
The wax onlxy embedded into an investment material with a sprue former — this forms a passage for molten metal to be poured through into the cylinder. This can protect remaining tooth structure.
It can also be used if there is minimal contour of remaining coronal tooth tissue with little retention. It is important to ensure adequate oral hygiene oncrustaciones providing any indirect restoration as failure to manage the caries risk of an individual may result in recurrent caries. 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.
Once the wax pattern is constructed the fabrication of this into the final restoration can begin, a method known as the Lost Wax Technique  is used. If a cuspal coverage onlay is required porcelain should be used as cuspal coverage with composite is contraindicated.
Le Courrier du Dentiste in French. The best instrument to use for this is a high-speed diamond fissure bur and the reduction should follow the inclination of the cusps and grooves as this will allow the preservation of more tooth tissue.

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 inncrustaciones substandard opposition to occlusal i. It is possible for these indirect restorations to be provided in one visit.
Laboratory procedures for inlays, crowns and bridges.
