An electro-surgical instrument and method is described for exposing gingival areas in preparation for a dental implant. The instrument includes an elongated handle, a leg extending perpendicular to the handle adjoined therewith, and a circular cutting loop. The loop is defined by a plane perpendicular to the leg and tangentially attached thereto along a circumference of the loop. The loop is formed of a unitary electrically conductive wire such as tungsten, and extends into the leg and at least partially into the handle. A high frequency current is passed through the wire into the loop to best activate the latter for cutting the gingival areas.
