Osseointegrated implants have published on single tooth replacements and new prosthodontic concepts which were developed following new demands regarding abutment-screw stability and esthetics. It does require a prevent rotation system, between abutment and fixture. In tie IMZ® Implant system, abutments are intended to act as stress-breaking elements between the fixtures and its superstructures, but they do not have this prevent rotation capability so far. Answering this requirement, 3i® Company invented MOD titanium insert which makes possible for single tooth defects. This paper reports two cases, both using MOD titanium insert to prevent fixture rotation and e-PTFE membranes (Goa-Tex® Regenerative Material) which were used to correct incongruences between the implant and bone defects site by using guided bone regeneration procedure.
