| Outline of Final Research Achievements |
In order to fabricate apatite cement which enable to adhere to wetting bone, adhesive property was given to apatite cement. The apatite cement was composed of disodium hydrogen phosphate solution as liquid part and TTCP-DCPD powder as powder part. Atelocollagen was added into liquid part as thickener. The adhesive strength of apatite cement was increased as a function of atelocollagen concentration. However, even though several positive phenomenon were observed, the maximum adhesive strength was far weaker than the practical using strength. Further studies are needed in order to reinforce the bonding and adhesive strength to bone and apatite.
