Most implants (21\/25) were 10\u2003mm long, eight were inserted in type 2 bone, 12 in type 3 and five in type 4 bone. At implant placement, the mean residual bone height (RBH) under the maxillary sinus was 5.4\u00b12.3\u2003mm; it was 5.7\u00b12.6\u2003mm on the mesial side and 5.1\u00b11.9\u2003mm on the distal side. Nineteen implants had less than 6\u2003mm of bone on at least one side and six implants had less than 6\u2003mm on both sides. A healing period of 3\u20134 months was allowed before abutment tightening at 35\u2003Ncm. The percentage of stable implants at abutment tightening and at the 1\u2010year control was calculated. The endo\u2010sinus bone gain and the crestal bone loss (CBL) at the mesial and distal sides were measured.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> Abutments were tightened after 3.1\u00b10.4 months. All implants but one (96%) resisted the applied 35\u2003Ncm torque. At the 1\u2010year control, all implants were clinically stable and supported the definitive prosthesis. All showed endo\u2010sinus bone gain; the mean gain was 2.5\u00b11.2\u2003mm. The mean CBL was 1.2\u00b10.7\u2003mm. Endo\u2010sinus bone gain and RBH showed a strong negative correlation (<jats:italic>r<\/jats:italic>=\u22120.78 on the mesial side and \u22120.80 on the distal side). A good correlation (<jats:italic>r<\/jats:italic>=0.73) was found between implant penetration in the sinus and endo\u2010sinus bone gain.<\/jats:p><jats:p><jats:bold>Conclusion: <\/jats:bold> Elevation of the sinus membrane alone without addition of bone grafting material can lead to bone formation beyond the original limits of the sinus floor. Despite a limited RBH at implant placement, a healing period of 3 months was sufficient to resist a torque of 35\u2003N\u2003cm and to lead to a predictable implant function at the 1\u2010year control.<\/jats:p>","DOI":"10.1111\/j.1600-0501.2006.01264.x","type":"journal-article","created":{"date-parts":[[2006,8,31]],"date-time":"2006-08-31T09:45:00Z","timestamp":1157017500000},"page":"679-686","source":"Crossref","is-referenced-by-count":104,"title":["Osteotome sinus floor elevation without grafting material: a 1\u2010year prospective pilot study with ITI implants"],"prefix":"10.1111","volume":"17","author":[{"given":"Rabah","family":"Nedir","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Mark","family":"Bischof","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Lydia","family":"Vazquez","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Serge","family":"Szmukler\u2010Moncler","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jean\u2010Pierre","family":"Bernard","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2006,8,31]]},"reference":[{"key":"e_1_2_6_2_1","doi-asserted-by":"publisher","DOI":"10.1016\/S0300-9785(81)80077-4"},{"key":"e_1_2_6_3_1","first-page":"151","article-title":"Treatment planning and placement of implants in the posterior maxilla","volume":"8","author":"Bahat O.","year":"1993","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_6_4_1","first-page":"646","article-title":"Br\u00e5nemark system implants in the posterior maxilla","volume":"15","author":"Bahat O.","year":"2000","journal-title":"International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_6_5_1","doi-asserted-by":"publisher","DOI":"10.1054\/ijom.2002.0459"},{"key":"e_1_2_6_6_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2006.01271.x"},{"key":"e_1_2_6_7_1","first-page":"613","article-title":"Grafting of the maxillary floor sinus with autologenous marrow and bone","volume":"38","author":"Boyne P.","year":"1980","journal-title":"Journal of Oral Surgery"},{"key":"e_1_2_6_8_1","doi-asserted-by":"publisher","DOI":"10.1111\/j.1600-0501.2004.00988.x"},{"key":"e_1_2_6_9_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1998.090402.x"},{"key":"e_1_2_6_10_1","first-page":"219","article-title":"Localized management of sinus floor with simultaneous implant placement.
