Justi (1834-1922) became a manufacturer of dental supplies and false teeth shortly after his arrival in the U.S. around 1850. He devised new molds that allowed a colored veneer to cover the Vulcan rubber base. He presented his method to the Orum and Armstrong Tooth Co. which promptly hired him. Justi soon became a partner in the firm and bought out his partners in 1864 to form the H.D. Justi Co. Justi's dental appliance company became nationally prominent. Before his inventions, porcelain teeth were hand crafted for each patient. His techniques turned it into a more standardized manufacturing process. He soon opened a new large manufacturing space and dental supply shop, and in 1886 they built a large factory at 32nd & Spring Garden in Philadelphia. He revolutionized the false teeth industry.
