Textured Cytoflex ® Tef-Guard ® non-resorbable barrier membrane is made of micro porous ePTFE material. The micro porosity of Cytoflex ® Tef-Guard ® is designed to resist the penetration of fibroblasts and bacteria, while simultaneously allowing the exchange of interstitial fluids through the membrane. The unique micro porous design enhances the gingival tissue attachment and provides a favorable protected environment for neo-vascularization and re-population of osteoblasts in the bony defects. The flexible material easily conforms to the bony defects of grafted sites, and can be easily retrieved as one piece after completion of bone growth. The bacteria-impenetrable membrane protects the tissue regeneration site despite flap recession or if primary closure is not obtained.

  • • Porosity is less than 0.3 micron (to prevent bacteria penetration), and the thickness is 250 micron
  • • Better host tissue attachment with fewer flap dehiscence
  • • Macro texture surface for better flap attachment
  • • Easily tagged with bone screws or pins
  • • Excellent handling and ease of use

What is the difference between the Smooth and Textured Cytoflex® Tefguard® barrier membranes? What are the benefits of each as opposed to the other?

Both Cytoflex® Tefguard® membranes have micro-texture. The micro texture allows for better soft tissue attachment over the membrane and a better seal around the bone graft area. The Textured Cytoflex membranes also provide a visible macro-texture similar to the configuration of strawberry fields as opposed to the conventional pot-hole design of other barrier products. This strawberry field texture was designed to further enhance soft tissue attachment and minimize dehiscence over the grafting site.

Is the Cytoflex® membrane textured on both sides?

The Cytoflex® Tefguard® micro pore texture surface is equally present on both surfaces. Additionally, both our Textured Cytoflex® Tefguard® and Cytoflex® Tefguard® Ti-Enforced membranes have macro texture surfaces on both sides. Advantages of Macro Texture on Both Surfaces The doctor does not have to be concerned about which side should face up toward the gingival tissue or face down toward the bone graft material. This makes it easier for the doctor to use the membrane. The texture surface provides more surface area for the gingival tissue to adhere to the membrane, and to stabilize the wound site. The texture surface facing the bone graft material, prevents the membrane from sliding around the graft material and make it easier to position the membrane over the graft material.

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

Micro porous Cytoflex® Tefguard® was designed to improve upon experiences learned from Gore-Tex® and Cytoplast® membranes. Macro porous Gore-Tex® 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. The featureless Cytoplast® membrane was designed to block off soft tissue and bacteria ingrowths, allowing the barrier to be used in non-primary coverage conditions. The relatively non-porous nature of the barrier limits nutrient permeation across the membrane. Cytoflex® Tefguard's® proprietary micro pores 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 micro porous texture enhances soft tissue attachment while preventing bacteria penetration across the membrane.

What about primary soft tissue coverage of the membrane?

Cytoflex® Tefguard® 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. The membrane was designed to block off bacteria and thus exposure of the membrane does not result in infection and case failure.

How long can the membrane stay in place?

In general within four to five weeks the membrane will need to be removed. This will allow enough time for the osseous tissue to begin forming and to be able to resist soft tissue from invading the graft site. However, at the discretion of the clinician, primary closure and longer healing times may be considered, if desirable.

How to remove the membranes?

Under primary coverage condition, Cytoflex® Tefguard® 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 lifted with a periodontal probe and extracted with a forcep. 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.

Can unused portions of the membrane be resterilized?

No, Cytoflex® Tefguard® membranes are designed for a single use only.

What is the shelf life the Cytoflex® Tefguard® membranes?

Each sterile Cytoflex® Tefguard® barrier is double packed and has 6-year of shelf life from the date of manufacture.

Have you ever had a confirmed allergic reaction to micro porous Cytoflex® Tefguard® membranes?

Cytoflex® Tefguard® membranes are made of inert and biocompatible PTFE materials. Since it was cleared in 2002, there have not been any reported allergic reactions caused by Cytoflex® Tefguard® PTFE barrier.

Are there any contraindications?

Cytoflex® Tefguard® membrane is a passive, non-load bearing material and should not be used for load bearing applications. Cytoflex® Tefguard® should not be considered for patients where general oral surgery is not advisable.

What are the potential complications?

Possible complications associated with any oral surgery include infection, flap slough, perforation, abscess formation, bone loss, pain and complications associated with the use of anesthesia. Depending upon the type and severity of the complication, as judged by the clinician, early material removal may be required.
