title: [Experimental study of cattle bone grafting in combination with implant insertion].
abstract: OBJECTIVE
  To study the effect of cattle bone grafting in combination with implant insertion.
  
  
  METHODS
  Twenty cattle bone blocks were onlayed on the rabbit tibial metaphysis, which were fixed by dental implants. Triple fluorochromes were sequentially given to animals following the operation. New bone formation was histologically and histomorphometrically evaluated.
  
  
  RESULTS
  The fluorochrome-labelled new bone gradually replaced almost all the spongy bone and the partial cortical bone of the graft at the end of the experiment. There was a significant higher percentage of bone area at the first four thread levels at 84 days than at 21 days. The average mineral apposition rates ranged from 1.90 microns/d to 2.75 microns/d.
  
  
  CONCLUSIONS
  The onlay cattle bone grafting in conjunction with screw-type dental implants can be used to increase the volume of the recipient bone.
