incisal edge
Pronunciation: in-SY-zul
The thin cutting edge of a front tooth (incisor or canine), as distinguished from the occlusal surface of posterior teeth.
Full Definition
The incisal edge is the biting edge of anterior teeth — incisors and canines. In dental laboratory documents, it appears in descriptions of restoration length, translucency requirements, and ceramic layering instructions (e.g., 'incisal translucency,' 'incisal halo'). Editors must not substitute 'occlusal' for 'incisal' when referring to anterior teeth; these anatomical terms are not interchangeable. 'Incisal' is always an adjective in standard dental usage.
Usage
Usage note: 'Incisal' applies only to anterior (front) teeth. Use 'occlusal' for molars and premolars. Never interchange these terms.
In Context
- "The ceramist was instructed to add incisal translucency to mimic the patient's natural enamel." — Laboratory work order
