Preparing cavities in the enlarged plaster teeth, carvedin the Dental Anatomy Technic Course. Prepare several typical form pit and fissure and smoothsurface cavities. The cuttings are to be made with vulcanitechisels and scrapers, after drawing the outline form withpencil. Deepen the convenience angles with hatchet and hoeexcavators and chisels. In case no enlarged plaster teeth are carved in the DentalAnatomy Course, excellent preliminary cavity preparationwork may be done on the models here illustrated, and 171, which the author has found very valuable inhis own classes. The teeth were first carved in modellingcomposition from Blacks average measurements, enlargedfive times. From these, sectional plaster molds were made,which were then duplicated in Babbits met
