overhang removal o·ver·hang re·mo·val (ō'vĕr-hang rĕ-mū'văl) Recontouring procedures that correct defective margins of restorations to provide a smooth surface to deter bacterial accumulation. If a minor amalgam overhang is acting as a plaque trap and preventing effective plaque control, the excess amalgam can be removed using a specialized powered instrument tip for this purpose. |
