TFE Regenerative Membranes are sterile non absorbable membranes made from polytetrafluoroethylene (PTFE) polymer.
PTFE is a biologically inert and tissue compatible material. The PTFE Regenerative Membranes have been proved to be pyrogen free. PTFE Regenerative Membranes for Guided Tissue Regeneration (GTR)are used to prevent migration of cells from epithelial and connective tissues, what could cause bone growth inhibition, thus providing a proper space for the formation of a natural fibrin structure, which is the bone precursor.
PTFE Regenerative Membranes are manufactured according to the requirements of the European Pharmacopoeia.
Indications – Use
PTFE Regenerative Membranes are temporarily implantable material used in periodontics, implantology and any dental surgical procedure that requires a mechanical barrier. The membranes provide a mechanism for the ingrowth of new soft tissues and they are used as a space making barriers for the treatment of periodontal defects.
Carefully open the outer tray of the double blister and aseptically remove the inner sterile tray which contains the PTFE Regenerative Membrane. The sterile barrier membrane then can be removed from the sterile inner tray for usage during the surgical procedure.
Clinical judgment must be used in selecting patients who will benefit from tissue regeneration, selecting and implanting the appropriate configuration for the defect, and treating patients postoperatively.
If additional stability is desired, the membrane can be stabilized with sutures, surgical tacks and screws.
When removal is desired, the membrane can be easily removed by grasping with forceps. Anesthesia may be provided to enhance patient comfort, but is usually not necessary.
Following membrane removal, the regenerated tissue will re-epithelialize within 14 to 21 days to complete the initial healing process. However, the final bone maturation will not occur for 6 to 12 months.
PTFE Regenerative Membranes like all the other membranes, should not be placed on existing active infection .
Warnings / Precautions / Interactions
PTFE Regenerative Membranes should be used only from members of experienced surgical teams. The use of the product under inadequate surgical techniques and biosafety conditions may harm the patient, leading to unsatisfactory results.
In case of infected wounds acceptable surgical practices should be followed. If occur complications impossible to be controlled, tissue inflammation or evidence of infection it is recommended the immediate removal of the material.
It is recommend a second surgery to remove PTFE Regenerative Membrane.
PTFE Regenerative Membranes are sterilized with Ethylenoxide gas. It is intended to be used only once and it should be discarded if its package is damaged or opened. Unused open membranes must be discarded and should not be resterilized.
Store bellow 25οC, away from direct heat and moisture. Never use after expiration date.
