The American Eagle XP2 Technology Double Gracey posterior (a) is a hybrid instrument that combines the access of a Gracey with the versatility of a universal curette, specifically designed for posterior mesial surfaces. It utilizes a proprietary sharpening-free finish and a Quik-Tip screw-in system, allowing clinicians to replace individual tips on a reusable handle. This configuration maintains a thin blade profile for precise subgingival debridement without the need for manual edge maintenance.
