title: [A clinical study on immediate implantation of particulate hydroxylapatite artificial bone after teeth extraction].
abstract: OBJECTIVE
  The aim of this study is to investigate the effect and complication of immediate implantation of particulate hydroxylapatite artificial bone after teeth extraction.
  
  
  METHODS
  Particulate hydroxylapatite artificial bone was implanted into 65 extraction sockets after teeth extraction. All patients were followed up until 3 months after the operation. They are examined with clinical examination and X-ray examination to observe the effect and complication of the implantation operation.
  
  
  RESULTS
  The wound healed well in all cases without any complication. Compared to the alveolar ridge before teeth extraction, and the height of the alveolar ridge after teeth extraction didn't decrease.
  
  
  CONCLUSIONS
  Implantation of particulate hydroxylapatite artificial bone after teeth extraction could maintain the height of the alveolar ridge and reduce the complication of teeth extraction. It would be helpful for the following prosthetic restoration. The immediate implantation of artificial bone is therefore needed further study.
