The object of the present invention is to provide an implant that enables functional periodontium formation around the implant after transplantation of a dental implant. In some aspects of the present invention, a tooth germ tissue-derived or a periodontal membrane tissue-derived cell mass is placed on the surface of the implant, and the surface of the implant on which the cell mass is placed is the whole or a part of the surface which is surrounded by the alveolar bone of the recipient at the time of implant transplantation.

Dental implant and method for producing same

The object of the present invention is to provide a technology that enables long-term preservation while maintaining the function of an organ or tissue for transplantation. A further object is utilizing this technology to provide a technology for suppressing tissue disorder accompanying warm ischemia and reperfusion as well as restoring an organ from a cardiac arrest donor to a level compatible for transplantation. A method that employs perfusion by a perfusate etc. is provided, comprising each of the following steps of: (a) connecting a perfusate instream cannula for streaming said perfusate into said 'organ or tissue,' (b) connecting a perfusate outstream cannula for streaming said perfusate out from said 'organ or tissue,' and (c) perfusing a perfusate comprising an oxygen carrier and a blood coagulation inhibitor into said organ or tissue.
