title: Osteotome sinus floor elevation without bone grafting and simultaneous implant placement in the atrophic maxilla: a pilot study.
abstract: OBJECTIVE
  This study evaluated the clinical and radiographic outcome of implants placed in the posterior maxilla with the osteotome sinus floor elevation (OSFE) technique without graft material.
  
  
  METHODS
  Twenty-seven 4.1-mm-diameter dental implants (Straumann AG, Basel, Switzerland) were placed to 17 sinuses with residual bone height of ≤ 10 mm and ≥ 5 mm to rehabilitate 23 molar and 4 premolar sites. Implants were simultaneously placed with the OSFE procedure without graft material.
  
  
  RESULTS
  All implants were successfully integrated after 8-12 weeks healing time. At the 2-year follow-up, all the implants presented the survival criteria proposed by Buser et al. and Cochran et al.
  
  
  CONCLUSIONS
  The OSFE technique without grafting material may be predictable because the success rate was 100% in this study. Implants gained endo-sinus bone despite the lack of graft material. More patients and longer follow-up are needed to validate the results of this pilot study.
