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.
