Introduction

The hard palate (palatum durum) forms the rostral roof of the oral cavity. It merges caudally with the soft palate.

Functional Anatomy=

  • Bony shelf of palatine processes of the incisive, maxillary and palatine bones. Failure of the palatine bones to fuse results in cleft palate.
  • 6-8 fixed transverse ridges
