ABSTRACT:
The invention relates to a plastically deformable implant for inserting into bodily orifices of the human or animal body. Implants of this type are used, for example, in ophthalmology, in particular, as vitreous body or lens replacements and in dentistry, for example, for filling extraction cavities in jaw-bones. Known implants, however, are not suitable for long-term use. The invention aims to provide a deformable plastic implant which also has a long-term application. This is achieved by the fact that the implant consists of a gel which is not sealed, containing fluorocarbon and which is directly introduced into the natural, or artificially created bodily orifice.
