In dentistry, an inlay is usually an indirect restoration (filling) consisting of a solid substance (as gold, porcelain or less often a cured composite resin) fitted to a cavity in a tooth and cemented into place.[1] This technique involves fabricating the restoration outside of the mouth using the dental impressions of the prepared tooth,
rather than placing a soft filling into the prepared tooth before the material sets hard.
