title: [Osteotome sinus floor elevation technique without grafting material: clinical analysis of eight cases].
abstract: OBJECTIVE
  To study the clinical results of XIVE implants placed immediately after sinus floor elevation using osteotomes without bone grafting.
  
  
  METHODS
  Totally 14 XIVE implants were placed in 8 patients immediately after sinus floor elevation using osteotomes without bone grafting. The survival rates of the implants during the prosthodontic process and six months after the crowns fabricated were recorded and analyzed.
  
  
  RESULTS
  One implant was loosen and extracted during the prosthodontic process and no implant failed six months after the crowns were placed. The survival rate of the implants in this study was 92.9%.
  
  
  CONCLUSIONS
  Implants placed immediately after sinus floor elevation using osteotomes without bone grafting could achieve higher survival rates, which is similar to the reported survival rates in dental implants with bone grafting.
