intaglio surface
Pronunciation: in-TAL-ee-oh
The interior, tissue-contacting surface of a dental prosthesis or restoration that faces the prepared tooth or soft tissue, as distinct from the polished external surface.
Full Definition
The intaglio surface is the concave, internal surface of a restoration—such as a crown, denture, or removable partial denture framework—that directly contacts the prepared tooth structure, implant component, or mucosal tissue. In crowns, the intaglio must precisely mirror the die surface to ensure adequate seating and marginal seal. In complete dentures, the intaglio bears the impression of the underlying ridge and is critical for retention and comfort. Technicians assess the intaglio with disclosing paste to identify pressure points before delivery. Editors must not confuse this term with 'cameo surface,' which refers to the visible external surface of a denture.
Usage
Usage note: Note the pronunciation (in-TAL-ee-oh); editors unfamiliar with Italian-derived terms may misspell or mispronounce this. Always contrast with 'cameo surface' in denture contexts.
