THE PROSTHETIC CORRECTION OF CLEFT PALATE outer edges of the lingual wings of the obturator-model for the seating of that por-tion of the palatal or lingual cast C, Fig. 31. PreHminary to fitting it into theflask, therefore, the lingual surface A, Fig. 29, should be evenly trimmed parallelto the line of the lingual wings and general plane of the obturator-model. Thenby outlining with a pencil the inner edge of the flask upon the model, as shown bythe dotted line in Fig. 25, it can be roughly trimmed, and the space between itand the flask filled with plaster. The nasal surface of this plaster-model should bebeveled even with the dividing line of the flask b, Fig. 30. Fig. 29. Fig.
