A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . The lingual and nasal aspect of plaster working-model A. Figs. 19 and 20 represent respectively, lingual and nasal views of a plastermodel of a typical cleft similar to that shown in Fig. 1. In trimming the model, thesurfaces a and b—lingual and nasal aspects—should be trimmed parallel tothe occlusal plane. The distance between these two surfaces will make the body ofthe model about one-half to three-fourths of an inch thick; though when fitted tothe flask, it will be much thinn

Preserve the model of the nasal floor to its outerborders e and the lingual surface f to about one-quarter of an inch beyondthat required for the palatal or lingual extensions of the obttirator, shown by thedotted lines. Trim the posterior ends c c of the model diagonally, as shown,for the final drawing sixrfaces of the casts.
