title: [Clinical use of beta-tricalcium phosphate ceramics with patient's own bone in maxillary elevation with osteotome].
abstract: OBJECTIVE
  To evaluate the clinical value of using the patient's autogenous bone mixed with beta-tricalcium phosphate ceramics(β-TCP) for maxillary sinus lift with simultaneous implantation.
  
  
  METHODS
  Patients with loss of posterior teeth and bone height of maxillary sinus floor between 4-10mm underwent internal sinus floor elevation, the proportion of bone to β-TCP was 1:1 and the mixture was inserted into the sinus floor. All cases had simultaneously placed ITI implants.The final crown fabrication was taken 4-6 months after implanting.
  
  
  RESULTS
  Twenty-one implants were inserted in 16 cases, the mean increase height was 4.2mm(2-6mm). There was clinical complaint of maxillary sinus inflammation in 1 case within 2 weeks, but the symptoms disappeared after antibiotic therapy. The remaining of 20 implants had no obvious complications. All implants had loaded for 32 months and were stable and well osseointegration on X-ray film.
  
  
  CONCLUSIONS
  Maxillary sinus elevation with simultaneous implantation is an easy procedure. Implants can be stable for a long time.
