Many prosthodontic situations demand an additional set of complete dentures. In such cases, the additional set can be made by duplicating the existing ones. Sometimes it is desirable to make a few changes when making new complete dentures for a patient who has been wearing old dentures for a long time and is satisfied with them. Replica dentures can be made for these patients, and success with the new dentures can be assured. A procedure is presented for duplication of the old dentures with intact intaglio but attrided occluding surface.
