obturators01obturators02Hard and soft palate defects are best treated with an obturator or speech aid prosthesis regardless of the presence or absence of teeth. Saving as much of the upper jaw as possible without compromising tumor resection is important. Retention of key teeth (eg, cuspids, first molars) helps enhance prosthesis stability and support. The obturator seals off the surgical defect and significantly improves speech and prevents leakage of fluids through the nose.
