The present invention is an impression cap for use with an implant/abutment impressioning system for taking impressions of cement-on-crown abutments to mirror the contour of the soft tissue and bone in a patient's mouth. The impression cap is configured to uniquely fit over one of an abutment and a dental implant via a novel flange. The flange is located at the bottom of the impression cap forming a bottom rim and is constructed to grasp the collar of an implant in a press, friction fit manner. The flange of the impression cap automatically captures the implant margin by pushing gingival tissue away when the component is seated.
