This paper presents 3\u2010year data assessing bone\u2010level changes around implants.<\/jats:p><jats:p><jats:bold>Material and methods: <\/jats:bold> Twenty\u2010five implants were placed in 17 patients to rehabilitate 16 molar and nine premolar sites. The mean residual bone height (RBH) was 5.4 \u00b1 2.3\u2003mm. A healing period of 3\u20134 months was allowed before abutment tightening. Most implants (21\/25) were 10\u2003mm long, and the others were 8 and 6\u2003mm long. At the 3\u2010year control, endo\u2010sinus bone gain, implant length protruding into the sinus and crestal bone loss (CBL) were measured on periapical radiographs.<\/jats:p><jats:p><jats:bold>Results: <\/jats:bold> All implants fulfilled the survival criteria. Despite the absence of grafting material, implants were embedded into newly formed bone tissue. All implants gained endo\u2010sinus bone; the mean gained bone was 3.1 \u00b1 1.5\u2003mm. The residual protrusion length decreased from 4.9 \u00b1 2.1 to 1.8 \u00b1 2.1\u2003mm. CBL was 0.9 \u00b1 0.8\u2003mm.<\/jats:p><jats:p><jats:bold>Conclusions: <\/jats:bold> This study confirms that the OSFE procedure without grafting material is sufficient to create bone beyond the natural limit of the sinus. On the mid\u2010term of 3 years, the technique was found to be predictable in the posterior maxilla when the RBH is limited. Implants gained endo\u2010sinus bone despite the lack of grafting material. Bone gain was still improving over the first\u2010year control. No shrinkage of the augmented area was observed.<\/jats:p>","DOI":"10.1111\/j.1600-0501.2008.01696.x","type":"journal-article","created":{"date-parts":[[2009,3,11]],"date-time":"2009-03-11T11:34:19Z","timestamp":1236771259000},"page":"701-707","source":"Crossref","is-referenced-by-count":64,"title":["Osteotome sinus floor elevation technique without grafting material: 3\u2010year results of a prospective pilot study"],"prefix":"10.1111","volume":"20","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":"Nathalie","family":"Nurdin","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":[[2009,6,4]]},"reference":[{"key":"e_1_2_6_2_1","first-page":"11","article-title":"The long\u2010term efficacy of currently used dental implants","volume":"1","author":"Albrektsson T.","year":"1986","journal-title":"The International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_6_3_1","first-page":"799","article-title":"A 5\u2010year longitudinal study of the clinical effectiveness of ITI solid\u2013screw implants in the treatment of mandibular edentulism","volume":"6","author":"Behneke A.","year":"2002","journal-title":"The International Journal of Oral & Maxillofacial Implants"},{"key":"e_1_2_6_4_1","doi-asserted-by":"publisher","DOI":"10.1034\/j.1600-0501.1997.080206.x"},{"key":"e_1_2_6_5_1","first-page":"221","article-title":"Sinus bone grafting procedures using ultra\u2010sonic bone surgery.
