(a–d): Computer-assisted planning of the IPS Implants^® Preprosthetic, along with a prosthodontic backward plan superimposed (a,b). Leaving out both mental foramina is ensured; anchorage is planned far away from the transition of the posts through the radial forearm flap (a,b). The orthopantomogram shows, in addition to the aforementioned implant, two conventional bone-level implants, placed using guided drilling, in the lower right first and second premolar region (c). The intraoral view displays the temporary prosthesis on the mandibular subperiosteal implant.
