gingival contour
The shape and profile of a prosthetic restoration at and below the gumline, designed to replicate or complement natural tissue anatomy.
Full Definition
Gingival contour refers to the three-dimensional form of a dental prosthesis where it meets or emerges from the soft tissue. In dental laboratory work, achieving accurate gingival contour is critical for aesthetics, tissue health, and preventing plaque accumulation. Technicians must follow the laboratory prescription closely to replicate the emergence profile dictated by the clinician. Poor gingival contour can lead to food trapping, periodontal irritation, or an unnatural appearance. Editors should note this term is distinct from 'gingival margin,' which refers to the edge of the gum tissue itself.
Usage
Usage note: Do not confuse with 'gingival margin.' Gingival contour describes the shape of the prosthesis; gingival margin describes the edge of the gum tissue.
