A resin acrylic and plaster solder index technique for realigning an ill-fitting fixed partial denture framework.

A resin acrylic and plaster solder index technique is a simple, accurate, secure, and cost-effective way to intraorally realign an ill-fitting fixed partial denture framework. Once the fixed partial denture framework is sectioned and segments are found to fit, an intraoral index preserves the correct relationship among segments and holds castings together securely enough to avoid separating until they can be embedded in solder investment and soldered in the dental laboratory. This technique is described here, together with a literature review and a discussion of the technique's advantages relative to other indexing techniques and materials.
