Abstract
Artificial teeth are imported at present w India. Attempts were therefore made to utilise indigenous materials in their manufacture. Orthoclase (potash felspar) is found to be a good flux for high temperature artzficial teeth manufacture, but for its impurities it has to be very carefully selected and sorted. Nepheline Syenite gives good artificial teeth at comparatively lower temperatures. Different methods of the making of artificial teeth are discussed and tried along with their comparative properties. Firing of artificial teeth is found to be best in electric muffles. Annealing is done in the same kilns to give them proper strength to resist thermal shocks. A comparative study of imported artificial teeth has been made regarding their properties, composition and micro-structure. A brief scheme for the manufacture of 1000 teeth per day has also been worked out.
