Implanto-orthognathic reconstructive surgery. A preliminary report

Implanto-orthognathic reconstructive surgery (IORS) entails a combination of three different types of surgical involvement for the reconstruction of the atrophic mandibular or maxillary alveolar ridge. The surgery combines an orthognathic procedure with interpositional bone grafts and placement of osseointegrated implants by means of a transmucoperiosteal technique. The above-mentioned modified orthognathic technique includes three maxillary and two mandibular procedures. The osseointegrated compression screw implant (OCSI) is particularly suitable for this type of implanto-orthognathic reconstructive surgery as it may be placed transmucoperiosteally during this pre-prosthodontic reconstructive technique, thereby eliminating a second stage intervention.
