A practical treatise on the technics and principles of dental orthopedia and prosthetic correction of cleft palate . of thehard nasal floor, sufficiently far forward andlaterally, to sustain the body of the obturator;in the same manner as will be described forAicieft of the soft palate or krgcr clcf ts; and that no attempt should be made to obtain an exact impression of any part of the bifurcated velum. If a sufficiently extensive impression can be taken of the floor of the nares,whether for small or large clefts, there is no reason why an obturator for oneshould not be worn quite as successfully as for the other, without a sustainingdevice, and consequently with perfect restoration of speech capabilities; providingof course that the most scientific part of the work on the veil of the palate is prop-erly performed. This statement is well attested in the authors practice withcongenital clefts of almost every character and size. The case shown in Fig. 8 arose in practice before the days of the present ob-turator, and is the smallest congenital cleft that the author has ever attempted to. 440 PART IX. THE PROSTHETIC CORRECTION OF CLEFT PALATE correct. The operation for its correction consisted of a soft rubber artificial velumbuttoned to a thin narrow very flexible platinum-gold ribbon which extended froma narrow plate across the roof of the mouth sustained with clasps around the firstmolars. The nasal portion of the obturator was limited and yet sufficient to sustainit in place when held forward by the plate. Its veil was similar to the Kingsleyvela. This of course required frequent renewals, because of the rapid deteriorationof the soft rubber. One of the objectionable features in the employment of softrubber vela is: patients will not have them renewed as they should. In the construction of the present form of obturators for very small clefts,where there is a possibility of its falling into the grasp of the swallowing muscles,it is always advisable to
