Porcelain Inlays and Onlays
Inlays and onlays are similar to a filling or a crown, but they are made of porcelain or gold instead of resin materials. They tend to be stronger than composite resins. Both inlay and onlay restorations are considered to be very conservative to the tooth enamel and dentin, in comparison to a crown. An inlay, is similar to a filling, in that it resides inside the center of a tooth. An onlay is larger than an inlay, and usually covers a cusp. Most of the time the margins do not extend under the gum line, making it easier to keep clean, which makes it healthier for the gums. They are processed in a lab, then cemented in place with a composite cement. Onlays and inlays can also be made of yellow or white gold.
