Duplicating an existing denture or denture waxing to fabricate a surgical guide for implant placement is a common procedure.1 Hydrocolloid impression materials in duplicating jigs or flasks are often used to make the mold for the duplication process.2 Disadvantages to using hydrocolloid impression materials are: (1) the procedure must be accomplished immediately due to impression instability over time, and (2) these impressions often cannot be used more than once if the duplicated denture is not adequate. The use of vinyl polysiloxane materials will negate these disadvantages, but most duplicating jigs require large amounts of impression material, and the process can be expensive with vinyl polysiloxane materials. This article describes a technique using a reline jig, a layer of vinyl polysiloxane, and mounting stone to produce a reusable mold for denture duplication.
