USE OF LOW FUSING ALLOY IN DENTISTRY

Statement of problem. Low fusing alloy has been used in dentistry for remount procedures in both fixed and removable prosthodontics, in impl ant prosthodontics for the fabrication of solid implant casts, in maxi llofacial prosthetics as oral radiation shields, and in dental researc h for its unique properties. Previously, the use of low fusing alloy w as thought to offer a high degree of dimensional accuracy. However, mu ltiple in vitro studies have shown that its presumed dimensional accur acy may be questionable. Purpose. This article reviews the physical pr operties, metallurgical considerations of low fusing alloy, its applic ations in dentistry, and a safe, simple method of using low fusing all oy.
