title: [Clinical application of maxillary endossenous implant with edentulous ridge expansion technique].
abstract: OBJECTIVE
  To evaluate the application and the effect of edentulous ridge expansion(ERE) technique in maxillary endossenous implant placement.
  
  
  METHODS
  49 patients with maxillary alveolar ridge atrophy received edentulous ridge expansion using condenser. In order to be similar to natural root, dental implants were selected and placed to tooth missed sites according to the requirements of aesthetics, function and dimension.
  
  
  RESULTS
  49 patients with atrophied alveolar ridge received 86 implants. The labio-lingual width augmented from 3.3 to 5.4 mm and the alveolar ridge height from 2 to 7 mm 6 months after operation. The implants osseintergrated tightly with alveolar bone and second-step prosthesis was performed 6 months after implant placement.
  
  
  CONCLUSIONS
  The edentulous ridge expansion technique can meet the requirements of aesthetics and function and is applicable to endossenous implant placement in maxilla. The method is simple and valuable to clinical application.
