Quick Reference

A prosthesis used to close or cover a defect in the palate and restore the occlusion. The defect may be consequent upon the removal of a tumour or be congenital, as in a cleft palate. An obturator is usually made of resin or a rubberized material and may be hollow to reduce the weight.
