Gingiva expander with the regenerating function of periodental tissue

The invention, osteoinductive regeneration before, in the gingival expander is implanted into the gingiva, the gingiva expander growth factor: characterized in that the (growth factor GF) and hydrogel structure linked through a peptide linker (linker), periodontal It provides the gingival tissue expander function mounted. According to the present invention, the total can be shortened implant period, through the sustained release of growth factors weakened due to rapid tissue expansion to restore the gingival tissue from normal gingival tissue in a short time by shortening the gingival extended time within 4 weeks is.
