ABSTRACT:
A dental transfer coping for taking a dental impression of a patient's case in which information about the rotational position of an installed implant around its axis is preserved has plural impression interlocking elements arrayed on its outer surface. These elements are rotationally indexed to the ant-rotation device of the implant, and are uniformly arrayed around the coping so that the coping can be removed from the impression and reinstalled in it in many rotational positions without losing the rotational information of the implant.
