Which restoration is made of metal, acrylic or porcelain and does not involve the cusps of the tooth?

• A. Inlay
• B. Onlay
• C. Crown
• D. Veneer

Answer: (A)

An inlay is a conservative interior restoration that fits within the walls of a prepared cavity and does not involve the cusps of the tooth. It can be made from metal, acrylic, or porcelain and is cemented into place after decay or damage is removed, preserving the cusp tips. This contrasts with an onlay, which extends to one or more cusps; a crown, which covers the entire tooth including cusps; and a veneer, which is bonded to the front surface of a tooth. So the restoration made of metal, acrylic, or porcelain and that doesn’t involve cusps is an inlay.
