High-Density PTFE Barrier Membrane
permamem® is an exceptionally thin, non-resorbable and biocompatible membrane. It is composed of biologically inert, high-density polytetrafluoroethylene (PTFE), which acts as an efficient barrier against bacterial and cellular penetration, and can therefore be used for open healing in certain indications. In addition, an easy removal of the membrane is enabled as no adjacent tissue grows into it. permamem® maintains its structural characteristics both during the initial implantation and over the whole healing time.
  • 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.

Socket preservation using cerbaone® and permamem® - Dr. A. Caiazzo

Grafting of the extraction socket with small cerabone® granules.


Initial situation - A young female 34 years old lost her front teeth in an surfing accident and she had a 5 unit bridge supported by her upper left lateral and right canine. The restoration failed and both supporting crowns have exposed and leaking margins.

  • 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

Since permamem® can be used for open healing in socket- and ridge preservation, primary wound closure is omitted and the soft tissue contours are maintained. The missing flap closure avoids displacement of the mucogingival line thus preserving the attached gingiva. Likewise, the aesthetic outcome is improved as the non-surgical removal of the membrane after the healing time omits the need for big surgical incisions. After removal of permamem®, the primary healing process and the reepithelialization of the regenerated soft tissue is completed within about one month.
