[Acceptance of polytetrafluoroethylene by subcutaneous connective tissue].

The suitability of extended PTFE as a supporting matrix for subepithelial connective tissue was studied histologically. The main question was whether tissue was able to grow within the implant. After a maximum of seven months post-implantation, no signs of vascularisation but only isolated cells were found within the implant. The histological examination showed neither inflammation nor encapsulation of the implant.
