A soldering index made with 4-META adhesive resin

Soldering indexes are most often made of fast-setting impression plaster or autopolymerizing resin. Lack of adhesive bonding between these materials and the casting requires the use of a bulky index to support the fixed partial denture components. The advent of adhesive resins improves the quality of the index and simplifies the procedure. A procedure for making a soldering index with 4-META adhesive resin is described that involves direct bonding of the resin to the metal castings. This procedure is accurate, simple, and time-saving. It can be used inside or outside the mouth, in prosthodontic or implant dentistry.
