Cytoflex® Tefguard® is a non-resorbable expanded PTFE material membrane for use as a space-making barrier in guided tissue regeneration procedures. Composed of a proprietary micro-porous polytetrafluoroethylene ePTFE) thin film, Cytoflex® Tefguard® has a surface texture and porosity suitable for adhesion of host cells to the material while preventing passage and integration of bacteria within the interstices of the material. The supple membrane conforms easily to tissue contours, and yet offers sufficient stiffness to maintain a space over the bony defect.

• Allows nutrient permeation across the membrane for healthy bone regeneration.
• Resists fibroblasts and blocks bacterial penetration keeping the site safe from infection.
• Excellent Handling & Rigidity. Easily adaptable. Easily retrievable as one piece
• Better host tissue attachment with fewer flap dehiscences
• Easily retrievable as one piece
• Better host tissue attachment with fewer flap dehiscences
• Facilitates tissue regeneration despite flap recessions, or incomplete primary closure.

How is this membrane different from Gore-Tex® and Cytoplast TM membranes?

• Micro porous Cytoflex® Tef-Guard® e-PTFE membranes were designed to improve upon experiences learned from the Gore-Tex® and Cytoplast TM ¹membranes.

  
  

  Macro porous Gore-Tex® e-PTFE was the gold standard of barrier membranes for use under primary soft tissue coverage. The macro pores were designed for tissue ingrowths to stabilize tissue/barrier interface. However, membrane removal after bone regeneration is traumatic and primary closure is needed.

  
  

  The featureless Cytoplast TM membrane is a high density-PTFE (d-PTFE) membrane. d-PTFE, is manufactured specifically to eliminate expansion, and greatly reduce pores, resulting in a material with a submicron (0.2 μm) pore size. Because of this tiny pore size, bacterial infiltration into the site is eliminated with d-PTFE. d-PTFE was designed to block off soft tissue and bacteria ingrowths, allowing the barrier to be used in non-primary coverage conditions. The non-porous nature of the barrier limits nutrient permeation across the membrane. Furthermore, due to its surface, attachment to tissues with d-PTFE is weak, and thus removal of the d-PTFE membranes is a bit easier when compared to Gore-Tex® e-PTFE membranes.

  
  

  Cytoflex® Tef- Guard®’s is a micro-ePTFE membrane. The membrane was developed with proprietary micro pores that were designed to allow nutrient permeation and at the same time prevent penetration of soft tissue and bacteria across the membrane. The combination of nutrient diffusion and the micro porous texture enhances soft tissue attachment while preventing dehiscence occurrence. Furthermore, soft tissue in-growth is not significant enough with CytoFlex e-PTFE membranes, and so the material is easily retrieved. Finally, at the discretion of the practitioners, the Cytoflex® Tef- Guard®’s micro-ePTFE membranes have been used in primary coverage and non-primary coverage situation when soft tissue coverage is lacking. The membrane was designed to block off bacteria and thus exposure of the membrane does not result in infection and case failure.

How does one remove the membranes?

Under primary coverage condition, Cytoflex® Tef-Guard® membrane may be easily removed by creating a small incision in its proximity. With forceps, firmly grasp a border of the material and remove it from the tissue. Local anesthesia is normally used for this procedure. In non-primary coverage situation, the membrane may be removed by grasping with forceps and removing it with a gentle tug. After membrane removal, re-epithelialization will occur within two to three weeks to complete the healing process. Final bone maturation will take place for six to twelve months from the time of implantation. This time frame should be considered in treatment planning cases involving heavy prosthetic loading of regenerated bone.

What about primary soft tissue coverage of the membrane?

• Cytoflex® Tef-Guard® membranes were designed to serve as a barrier to contain the bone graft material and prevent soft tissue and bacteria in-growth. At the discretion of the practitioners, the barriers have been used in primary coverage and non-primary coverage situation when soft tissue coverage is lacking.
