ABSTRACT:
The outer shell possesses openings in the polar or apical region which serve to backfill the implanted shell with spongious bone material. The openings are separated by a web which extends through the axis of symmetry of the outer shell and which has a threaded bore to receive an insertion instrument. The instrument is centrally guided on an axial direction to facilitate control and alignment of the outer shell during insertion, especially in the case of outer shells to be screwed in with a self-cutting thread.
