Spacer made from a visible light-cured resin for processing denture soft liners.

When soft lining materials are used in complete dentures it is important to control their thickness and increase the probability of their staying in the denture base. A spacer made of light-curing denture base material makes it possible to do both of these things. The denture base resin is packed against the hard light-cured spacer and can be partially cured. The cured spacer will not flow or be displaced and can be easily removed to allow an even space for packing the soft lining material.
