IN A WORLD WITHOUT CASTINGS Could Cavities Be Filled?


Although there is some disagreement over who is most responsible for its invention, the dental inlay has had an undeniably profound impact on modern dentistry. Barnabas F. Philbrook introduced a pressure casting method


for producing gold fillings for cavities in 1896 that featured a wax pattern, sprue pin and metal ring inserted directly into the


patient’s mouth. Te pattern was removed, the wax was melted and the inlay was cast with air pressure. Te industry didn’t take notice until a decade later, when William H. Taggart invented a centrifugal cast- ing process in 1907, though he eventually lost a patent due to Philbrook’s previous work. Still, the process developed by these two dentists, with minor alterations, is still used to fill cavities today.
