ABSTRACT:
An Implant/Abutment Impressioning cap. The impression cap is multi-vented and configured to uniquely fit over an abutment/implant assembly and grasp the implant via a novel flange and internal geometry design. 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 internal geometry of the impression cap forms surfaces which mirror those of the abutment/implant assembly. The flange of the impression cap automatically captures the implant margin by pushing gingival tissue away when the component is seated.
