Ppermamem® is a 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 clinical 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.




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.

  • 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
  • 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

  • Socket and ridge preservation (open healing)
  • Horizontal/vertical augmentation
  • Fenestration and dehiscence defects
  • Intrabony defects (1 to 3 wall)
  • Furcation defects (class I and II)



permamem® fulfills the requirements of biocompatibility according to EN ISO 10993-1 and EN ISO 7405. It comes into contact with bone and soft tissue and is categorized as a medical device Class IIa according to Directive 93/42/EEC. The biocompatibility of the membrane has been proven by in vivo preclinical data [1].


permamem® is made of high-density polytetrafluoroethylene (PTFE). Energy-dispersive X-ray spectroscopy (molecular fingerprint) has demonstrated characteristic peaks of carbon and fluorine but no other phases were detectable. Because of its 100% synthetic composition any risk of infection can be excluded.

Easy handling

permamem® shows good handling properties thanks to its thin character (thickness ~ 0.08 mm). The rounded edges of the membrane avoid traumatization of the soft tissue. In open healing procedures, permamem® may easily be removed after the desired healing time in a non-surgical way with a pair of tweezers. If primary closure is obtained during membrane placement, opening of the surgical site will be required to remove the membrane.

Open healing

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 socket- and ridge preservation. The membrane should be removed after 3-4 weeks. This will provide sufficient time for the formation of the blood clot and a provisional matrix of woven bone in the alveole, which is the basis for the bony regeneration.

Easy recovery

permamem® can easily be retrieved for removal thanks to its blue color.

Application and Fixation

To ensure membrane stability and protection of the bone grafting material, permamem® should be placed in such a way that the membrane extends three to four millimeters beyond the edges of the bone defect. A minimum distance of one millimeter to the adjacent teeth should be maintained. It is recommended to fix permamem® by sutures, screws or pins.
