title: [Clinical study of maxillary sinus floor elevation with simultaneous placement of implants from the top of alveoli].
abstract: OBJECTIVE
  To evaluate the clinical results of maxillary sinus floor elevation technique with bone condensers on implantation.
  
  
  METHODS
  104 patients underwent maxillary sinus floor elevation and 126 implants were inserted and restored. Clinical examination and radiographs were conducted. Spiral CT scanning and three-dimensional reconstruction was performed among 30 cases during follow-up.
  
  
  RESULTS
  All the patients with 9.16 mm (5-11 mm) height of residual bone in the posterior maxilla underwent sinus floor elevation with simultaneous implant placement using bone condensers. The elevation height was 2-6 mm. The follow-up time was 16-82 months. No sinus complication was observed during the follow-up period. The survival rate was 100%. Spiral CT scanning and three-dimensional reconstruction showed that dental implants were submerged in the alveoli around, their tops were covered with bone.
  
  
  CONCLUSIONS
  With bone condensers, maxillary sinus floor elevation with simultaneous placement of implants from the top of alveoli was a predictable and safe technique. There were no implants loose or lost, no clinical complaint of maxillary sinus area, and X-ray examination showed well osseointegration.
