anatomical crown
The portion of a tooth covered by enamel, used as the morphological reference when designing the coronal contours of a dental restoration.
Full Definition
The anatomical crown is the natural enamel-covered portion of a tooth and serves as the morphological template that dental laboratory technicians replicate when sculpting restorations. It is distinguished from the 'clinical crown,' which refers only to the tooth structure visible above the gingival margin. In laboratory work orders and technical articles, 'anatomical crown' signals that contours, cusp heights, fossa depths, and ridge anatomy should match natural tooth morphology. Editors should recognise that 'anatomical contour' and 'anatomical crown form' are acceptable synonymous phrases in descriptive context.
Usage
Usage note: Distinguish from 'clinical crown' (visible above the gumline) in anatomical and clinical descriptions. The two are not interchangeable.
