NEW PTFE BARRIER MEMBRANE
permamem® 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.
PROPERTIES & ADVANTAGES
– 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
IMPLANTOLOGY, ORAL- & CMF SURGERY, PERIODONTOLOGY
– Socket and ridge preservation (open healing)
– Horizontal/vertical augmentation
– Fenestration and dehiscence defects
