Fabrication of a duplicate denture using visible light-polymerized resin as an interim denture base

This article describes a technique for producing a duplicate denture using a visible light-polymerized (VLP) denture base for support prior to processing. A 2-part mold of the original denture was made, and then a sheet of VLP resin was reduced to a thickness of 0.5 mm and adapted to the fitting surface of the mold to create a denture base. The base was polymerized and the remaining features, such as the teeth and polished surfaces of the denture, were reproduced in wax. This technique may be helpful when performing subsequent clinical and laboratory procedures.
