Palatal Vault
Pronunciation: PAL-uh-tul VAWLT
The curved anatomical roof of the oral cavity formed by the hard palate, referenced in implant dentistry as a connective tissue donor site for soft-tissue grafts.
Full Definition
In the context of dental implantology, the palatal vault is most commonly discussed as the primary harvest site for connective tissue grafts (CTGs) used to augment peri-implant soft tissue volume and improve keratinized mucosa around implants. The thickness of the palate varies between individuals and by region, and editors should be aware that 'palatal vault' may be used descriptively to indicate palate depth or curvature when discussing prosthetic design in complete-arch cases. The term should not be used as a synonym for 'hard palate' without context, as it specifically implies the arched three-dimensional form.
Usage
Usage note: When used in a surgical context, clarify whether 'palatal vault' refers to the anatomical structure or the donor-site region; avoid using it as a direct synonym for 'hard palate.'
