The combined application of artificial bone, rhbFGF and rhIGF-I was used, and they were randomly divided into experimental group and control group. The differences between the two groups were compared by observing the bite degree, periodontal pocket depth, periodontal index and histological changes before and after treatment.Expected results: The treatment effect of the experimental group will be significantly better than that of the control group, 精品文档---下载后可任意编辑manifested as a significant increase in the bite degree of dogs, a significant decrease in periodontal pocket depth, a significant reduction in periodontal index, an accelerated absorption rate of gypsum matrix in tissue histology, and a significant increase in new bone growth.Conclusion: The composite of rhbFGF, rhIGF-I and artificial bone can significantly promote periodontal tissue regeneration in dogs, and is expected to become an important part of new clinical treatment methods for periodontal disease.【Key words】 Periodontitis; rhbFGF; rhIGF-I; Artificial bone; Regeneration
