Experimental study of double-root implantation with the aid of template in rabbits

Abstract

Abstract: PURPOSE: 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.
