Dental inlaysIn 1907, gold dental inlays were first described in the U.S. by H. William Taggart, a Chicago dentist, at the New York Odontological Society. His invention of a method for casting gold inlays by the inverted pattern procedure used the ancient principle of the "disappearing core." The use of gold for the filling of dental cavities was first described a half century earlier, in Oct 1854. |
