A promising solution to what some perceive as a problem has been developed by the Collagen Corporation. Made of fine spun polytetra flour ethylene, it comes with an implantation device which makes it easier for doctors to put the implant material where it will do the most good. This is true of GoreTex as well. The reported advantage of the Softform material is that it is made in a tubular form. Because the implant has a hollow center cells can grow into the center of the implant and anchor it more firmly.
Rejection is then much less likely to occur.
The implants can also be used to smooth or accent the margins of the lip.
