title: [Clinical study of two fixed prosthetics in dentition defect of Kennedy I and II type].
abstract: OBJECTIVE
  To investigate the feasibility and clinical effect of two fixed prosthetic, supported by implant alone or by implant and natural teeth, in dentition defect of Kennedy I or II type.
  
  
  METHODS
  Sixty subjects with dentition defect of Kennedy I or II were collected. They were divided into group A and group B, 30 subjects in each group respectively. Group A was restore with PFM crown or bridge, supported by implant or implant combined with natural teeth. Group B was treated by cantilever fixed bridge supported by natural teeth. The treatment outcomes were analyzed with SPSS17.0 software package.
  
  
  RESULTS
  With 5 years of follow-up, all subjects in group A and 26/30 subjects in group B had successful restoration. There was significant difference in successful rate between group A and group B(P<0.05).
  
  
  CONCLUSIONS
  Fixed prosthetics supported by implant alone and by both implant and natural teeth, in dentition defect of Kennedy I or II is feasible and its clinical effect is satisfactory.
