Mesial Distal Combination combines the mesial tip of the Gracey 12 and the distal Gracey 13 tip to allow completion of the facial or lingual sextant without changing instruments. Nordent standard Gracey curettes feature a blade face curve with a true radius that conforms to tooth anatomy better than any other brand. This means that Nordent standard Gracey curettes are easier to adapt, require fewer strokes, and reduce tissue trauma better than any other brand. Nordent standard Gracey curettes have a 1.1 mm terminal shank diameter and blades that are 0.9 mm wide and 4 mm long. Featuring our DuraLite® ColorRings™ Handle.
