Abstract
Aims: 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.
Materials and 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.
Conclusion: 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.
