self-angulated curette

self-an·gu·la·ted cu·rette

(self-ang'gyū-lā-tĕd kyūr-et')
Device in which the face is tilted in relation to the lower shank (e.g., area-specific curette). Tilted face causes one cutting edge to be lower than the other on a working-end, which positions the working cutting edge in correct angulation to the root surface.
