Correction of the atrophic alveolar ridge by interpositional bone grafting: a progress report

A retrospective study of postoperative stability and osseous changes was made on nine patients with maxillary or mandibular atrophy who were treated with interpositional bone grafting techniques. There was minimal discernible positional change or resorption of the portion of the maxilla or mandible that was moved by interpositional grafting procedures. Sequential radiographs and cephalometric tracings showed early consolidation of the grafted bone, minimal resorption of the respositioned osseous segments, and a small decrease of alveolar ridge height during an average potsoperative follow-up period of seven months.
