Abstract: A system for mounting a dental prosthetic structure on a dental implant is disclosed which includes a mounting base for supporting the dental prosthetic structure, a transmucosal member for attachment to a dental implant and having an attachment portion for receiving the mounting base; and a fastener for affixing the mounting base to the transmucosal member. The mounting base has an end wall for supporting the dental prosthetic structure and a depending side wall engageable with the attachment portion of the transmucosal member. At least one of the transmucosal member and the mounting base is of angled configuration in longitudinal direction for supposing the respectively adjacent mounting base and prothetic structure at an angle to an axis of the implant for compensating implant angulation.
