The surgical modification was a bilateral sinus floor augmentation prior to the osteotomy. This generated a closed recipient bed which allowed the use of particulated bone grafts (xenogenic bone mineral) and a reduced amount of autologous iliac bone grafts.<\/jats:p><\/jats:sec><jats:sec><jats:title>Materials and Methods<\/jats:title><jats:p>A total of 106 patients with maxillary interpositional bone grafts were included in this retrospective analysis between 2006 and 2020. The panoramic radiographs and lateral cephalograms were analyzed to assess the gain and stability of the maxillary bone and the peri\u2010implant bone loss.

A mean of 0.20\u00a0\u00b1\u00a00.37\u00a0mm marginal bone loss was noted after 5\u00a0years. The implant survival was 96.4% after 5\u00a0years and implant success can be rated 91.7% in a mean follow\u2010up period of 93\u00a0months and 168\u00a0months maximal observation time.
