Restorations with marginal overhangs are frequently associated with localized periodontal defects. Access to overcontoured approximal margins of restorations can be difficult to obtain, however. A system featuring a multidirectional handpiece is an effective and efficient means of contouring, finishing, and polishing restoration surfaces and margins. In particular, the system facilitates access to approximal and subgingival areas for the removal of marginal excess and overhangs. This system may be a valuable addition to the practitioner's armamentarium for operative procedures.
