Abstract
508,204. Moulding artificial teeth. DENTAL RESEARCH CORPORATION. Dec. 28, 1937, No. 35939. Convention date, Dec. 28, 1936. [Class 87 (ii)] Relates to the moulding of hollov artificial teeth made of porcelain. Flexible material such as rubber, plasticised vinyl chloride, gel atine, glue, &c. is poured around a master core and a master tooth to pro duce cavities 6, 7, Figs. 1 and 3, in a flexible mould 5. A ring 15 having a radial wire with a downwardly projecting end 22 is then placed in a groove 11 so that the wire lies in a slot 24. Flexible material, wax, or resin is then poured into the cavity 6, and when it has set, the ring with the wax core is transferred to the groove 12, so that the core 25 lies in the cavity 7 formed by the master tooth. Porcelain 28 with a temporary binder is then poured into the space between the wax core and the walls of the cavity 7 and the mould is subjected to vibration by a device 32. When the porcelain is sufficiently compacted, the core with the porcelain is removed and dried by warming. The temperature is then raised to melt the wax, thus leaving the porcelain shell 28 ready for firing. The shells may be stained internally, for example by adding colouring materials to the temporary cores 25. The mould may have moulding cavities on four sides.
