Bone resorption and/or osteogenesis of the mandible in implanto-orthognathic reconstructive surgery.

Over a period of 18-48 months, the bone resorption, or bone deposition (osteogenesis) of the mandible, in the supero-inferior dimension, was evaluated in patients who had had implanto-orthognathic reconstructive surgery (IORS). It entails the combination of three different types of surgical involvement for the reconstruction of the atrophic (class V), and severely atrophic (class VI) mandibular alveolar ridge (Bütow and Duvenage, 1993). This type of surgical reconstruction combines orthognathic osteotomy, interpositional bone grafting and the immediate placement of osseointegrated implants by means of a trans-mucoperiosteal approach. Evaluation of the mandibular IORS over the long-term, has proven that not only is there minimal resorption, but that osteogenesis of the alveolar ridge occurs.

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.

Treatment of the facial skeleton in naso-maxillo-acro-dysostosis.

The extent of the naso-maxillo-acro-dysostosis involvement differs in each case. The three cases presented in this paper all had different orthodontic and surgical treatment approaches according to the individual involvement of the nose, maxillae, mouth and other facial features.

Pedicled "flap" from a tongue flap.

A pedicled musculo-mucocutaneous "flap" derived from an original tongue flap is used as one of the layers for the double-layered closure of a recurring oro-nasal fistula. The other layer used for the closure, namely the nasal "flap" layer, originates from the adjacent palatal mucoperiosteum. The oral pedicled "flap" layer and the nasal "flap" layer form the final double-layered flap. This technique gives satisfactory closure of the persistent oro-nasal fistula.
