Healing time before prosthetic rehabilitation was 10 weeks. One year after implant placement, bone levels were measured on standardized periapical radiographs.\n\nResults: Thirty-seven (17 tests, 20 controls) implants were placed in 12 patients with a mean maxillary residual bone height (RBH) of 2.4 \u00b1 0.9 mm. Before loading, two control implants failed (RBH 1.4 and 1.2 mm); two others rotated at loading (one test, RBH 0.9 mm; one control, RBH 1.5 mm) but were uneventfully loaded after three additional months of healing. These adverse events and complications occurred when implants were placed in merged corticals. Endo-sinus bone gain was 3.9 \u00b1 1.0 and 5.0 \u00b1 1.3 mm for the test and control groups (P = 0.003). The 1-year success rate was 100% and 90%, respectively (P = 0.49).\n\nConclusion: Although more bone is gained when grafting material is used, this may not be required to promote endo-sinus bone gain. The OSFE procedure with or without grafting material could be efficient when the RBH is<\/p>\n\n<p><strong>Keywords<\/strong><\/p>\n<p>Key words\n\nAtrophic maxilla, bone gain, bone graft, bone regeneration, crestal bone loss, dental implants, internal sinus lift, no grafting, osteotome sinus floor elevation, posterior maxilla, prospective randomized clinical trial, sinus-lift.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Authors Nedir R., Nurdin N., Khoury P., Perneger T., El Hage M., Bernard J.P., Bischof M.
