The present invention is to provide an impression coping for an implant operation, in which an abutment coupling groove is formed in a lower portion of a body, a protruding portion that is relatively greater in diameter than the lower portion is formed at an upper end, a protruding hook is formed to extend from one side of the protruding portion, and the body is formed to be relatively less in height than teeth adjacent to a missing tooth. The present invention provides the impression coping in which the height of the body is smaller than the height of conventional impression copings, and thus impression taking is allowed in a state where a patient does not open his or her mouth during an impression taking process, that is, in a state where the mouth is closed. Accordingly, a pain of the patient can be minimized and the operation can be improved in convenience and efficiency. |
