Cytoflex Textured Tefguard is a non-resorbable PTFE membrane made of a proprietary micro-porous expanded polytetrafluoroethylene (ePTFE) material, that is ideal for socket preservations and bone grafting procedures. The textured version of Cytoflex Tefguard has superficial macro texture overlapping the micro pore texture on both surfaces, providing additional grips for flap attachment. Overlaying macro and micro textures on both surfaces! Allows nutrient permeation across the membrane. Resists fibroblasts and blocks bacterial penetration. Excellent Handling & Rigidity. Easily adaptable. Easily retrievable as one piece. Enhanced flap grips with fewer flap dehiscences Facilitates tissue regeneration despite flap recessions, or incomplete primary closure. Available in 12mmx24mm and 25mmx30mm. Provided double pouched and sterile. Cytoflex Textured Tefguard Benefits The textured version of Cytoflex® Tefguard® has superficial macro texture overlapping the micro pore texture on both surfaces. The cellular level micro texture is invisible to the naked eye, but can be seen at high magnifications. The macro texture provides additional grips for flap attachment. 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. Cytoflex ® Tefguard ® - Clinical Case Review MINIMALLY INVASIVE IMPLANT SITE GRAFTING TECHNIQUE Jenchun Chen DDS This is a 38 year-old female who presented with a crown-root fracture of the mandibular first molar and a thin gingival biotype. An immediate implant placement following tooth extraction was planned. A flapless, minimally invasive extraction and implant placement combined with guided tissue regeneration was employed to minimize soft and hard tissue recession. The tooth root was extracted with an intrasucular incision and a periosteal elevator. The extraction socket was curetted to remove all soft tissue remnants. After an implant was placed into the extraction site, the gap between the implant and the socket wall was filled with bone graft particles (Figures 1 & 2). A Tefguard® ePTFE membrane was trimmed to extend 3 mm beyond the socket walls and then tucked subperiosteally under the lingual flap, the buccal flap and underneath the interdental papilla using a curette. The membrane was allowed to rest passively over the socket (Figure 3), and was stabilized with a criss-cross absorbable PGA monofilament suture without primary closure (Figure 4). After one-week post operation, the graft site was uneventful, and the suture was removed (Figure 5). At three-week post-operation, the soft tissue overlying the exposed membrane demonstrated healing without signs of inflammation. An inadvertent fold in the membrane (introduced during membrane placement) was found at the distal buccal corner (Figure 6). The decision was made to remove the membrane early to prevent potential complications as a result of the folding of the membrane. After applying topical anesthetic, the membrane was easily removed by grasping with a tissue forcep. A dense, vascular connective tissue matrix was found underlying the membrane in the extraction socket upon membrane removal. Figure 7 shows the site at one week after membrane removal. Following membrane removal, keratinized gingiva began to form over the grafted socket. At six-week post-operation, the soft tissue was stable with preserved interproximal papillae and natural mucogingival architecture (Figure 8). This case demonstrates the use of a less invasive grafting technique using a micro porous ePTFE barrier.
