High-Density PTFE Barrier Membrane
permamem® is an exceptionally thin, non-resorbable, biologically inert and biocompatible membrane made of high-density polytetrafluoroethylene (PTFE). permamem® maintains its structural integrity during implantation and over time. Due to its small pore size the membrane acts as an efficient barrier against bacterial and cellular penetration, and may therefore be left in place for open healing in certain indications. permamem® can easily be removed after the desired healing time with a pair of tweezers. After removal, the primary healing process and the reepithelialization of the regenerating soft tissue will be completed within one month.
  • Socket and ridge preservation (open healing)
  • Horizontal/vertical augmentation
  • Fenestration and dehiscence defects
  • Intrabony defects (1- 3 wall)
  • Furcation defects (class I and II)


permamem® can be easily manipulated and applied thanks to its thin character (thickness ~ 0.08 mm). The rounded edges of the membrane avoid traumatization of the soft tissues. In open healing procedures, permamem® may easily be removed after the healing time in a non-surgical way with a pair of tweezers. The blue color allow for easy recovery of the membrane.


permamem® should always be immobilized at the recipient site by pins, screws or sutures. For socket and ridge preservation, permamem® can be sutured to the periosteum or a periosteal flap to achieve a tight adaptation of the membrane to the recipient site.


The membrane can be cut to the desired shape and size with a pair of scissors or a scalpel while maintaining sterility.


permamem® should be removed after 3-4 weeks. An exposed membrane may be easily removed with tweezers. If primary closure is obtained during membrane placement, opening of the surgical site will be required to remove the membrane. After removal of permamem®, the primary healing process and the reepithelialisation of the regenerating soft tissue will be completed within one month.

  • 100 % synthetic PTFE barrier membrane
  • Ultra-thin (~0.08 mm)
  • Impervious to bacteria due to dense structure
  • Easily removable due to minimal tissue ingrowth into the surface structure
  • No need for primary soft tissue closure (indication-dependent)
  • Supports space maintenance (as compared to collagen membranes)
  • Easy recovery thanks to blue color
  • Rounded edges for minimal tissue trauma
  • Easy fixation with sutures or pins
  • Either side may be placed towards the defect site

permamem® for open healing (Dr. R. Rannula)
permamem® - PTFE barrier membrane

Open healing with permamem® in socket or ridge preservation enables maintenance of the soft tissue architecture and contours since no primary wound closure is required. Due to the missing flap closure, the mucogingival line will not be displaced and the attached/keratinized gingiva will be preserved. The non-surgical removal of the membrane after the healing time omits the need for big surgical incisions (vertical releasing incisions), thus improving aesthetics and patient comfort.
