title: [Clinical study of sinus elevation by hydraulic and implant placement followed by bone graft simultaneously].
abstract: OBJECTIVE
  To evaluate the clinical results and technique of sinus membrane hydraulic elevation followed by bone graft and implant placement simultaneously.
  
  
  METHODS
  Twenty-five patients were involved in the study (male:15, female: 10, age: 40-62 yrs). The mean residual ridge was (4.25±1.12) mm. Clinical examination were performed and radiographs were taken to evaluated the outcomes.
  
  
  RESULTS
  The mean elevated height was (8.50±2.12) mm and 25 implants were placed. Only one implant was lost due to infection 3 weeks after operation because of diabetes. Only minor complications were observed postoperatively in the remaining patients. Twenty-four patients were satisfactorily restored with the follow-up period of 12-18 months.
  
  
  CONCLUSIONS
  The technique of sinus membrane hydraulic elevation followed by bone graft and implant placement simultaneously displays minor complication, minimal discomfort and excellent success rate.
