title: [Tissue engineered bone scaffold material in restoration of alveolar socket after extraction of lower impacted third molar].
abstract: OBJECTIVE
  To investigate the effects of tissue engineered bone scaffold material in the restoration of alveolar socket after extraction of lower impacted third molar.
  
  
  METHODS
  Thirteen patients were immediately implanted with Bio-oss or PerioGlas® in the alveolar cavity after impacted mandibular third molar extraction. Clinical observation and X-ray were taken 1 to 12 weeks after operation. Paired t test was used for statistical analysis by SPSS10.0 software package.
  
  
  RESULTS
  Thirteen patients did not experience postoperative complications. The distal alveolar height of the second molar and the gingival attachment did decrease significantly 1 to 12 weeks after operation(P < 0.05).
  
  
  CONCLUSIONS
  Tissue engineered bone scaffold material is helpful in the restoration of alveolar socket after impacted third molar extraction.
