Abstract
An impression coping is provided for taking an impression of an implant installed in a patient's mouth. The impression coping comprises a proximal end and a distal end. The proximal end is adapted to be inserted within a coronal opening formed in the implant and has an anti-rotation formation cooperating with a corresponding anti-rotation formation formed in the implant for preventing relative rotation of the coping and implant. The coping further includes resilient fingers for engaging corresponding surfaces formed within the coronal opening of the implant. The distal end of the coping includes an impression portion adapted to be embedded in a dental impression material for taking a dental impression thereof.
