permamem®

HIGH-DENSITY PTFE BARRIER MEMBRANE

 

Ppermamem® 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.

 

OPEN HEALING IN SOCKET AND RIDGE PRESERVATION

 

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.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.

INDICATIONS

permamem® is a temporarily implantable membrane for use as a space-creating barrier in GBR and GTR.


IMPLANTOLOGY, PERIODONTOLOGY AND ORAL AND CMF SURGERY

– Socket- and ridge preservation (open healing)
– Horizontal/vertical augmentation
– Fenestration and dehiscence defects
– Intraosseous defects (1 to 3 walls)
– Furcation defects (class I and II)

PROPERTIES and ADVANTAGES

– 100% synthetic PTFE barrier membrane
– Ultra-thin (~0.08 mm)
– Impervious to bacteria due to dense structure
– Exceptional 360° tear strength
– 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

DETAILS

SPECIFIC FACTS

Biocompatibility

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].

SAFETY

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.

REMOVAL

permamem® should be removed in accordance with the indication. For extraction socket regeneration procedures, the membrane can be removed after three to four weeks. In case of larger bone defects and augmentations with bone substitute material, the membrane can usually be removed after approximately six months.

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.
