title: [Experimental study of double-root implantation with the aid of template in rabbits].
abstract: OBJECTIVE
  To evaluate the feasibility of double-root implantation with the aid of template.
  
  
  METHODS
  Implant templates were fabricated based on CT data from the tibia of 12 rabbits. 12 double-root implants were placed in the tibia of rabbits under the guidance of implant templates, and single-root implants were placed in contralateral tibia of the same rabbits. Rabbits were sacrificed at 8 and 12 weeks. Implant mobility was checked directly. Specimens were examined by X-ray to measure bone gray value using Image Pro-Plus6.0 software. Super-rigidity slices were prepared to test bone-implant contact ratio using Image Pro-Plus6.0 software. The data were analyzed with SPSS20.0 software package.
  
  
  RESULTS
  The surgical procedures were completed successfully. There was no obvious loosening of implants. No significant difference was found between the experimental and control groups in bone gray value and bone-implant contact ratio at different time(P>0.05).
  
  
  CONCLUSIONS
  The implanting method of double-roots implant with the aid of template is feasible, and osteointegration is ideal.
