Expert oral surgeons have estimated that a membrane used in Guided Bone Regeneration should maintain its barrier function until the provisional matrix and woven bone are present. As a consequence, barrier duration is considered to be necessary for 4 to 6 weeks, in most cases. Geistlich Bio-Gide® has proven to support bone regeneration on an equivalent level as membranes with a longer barrier function, with the additional benefit of complication-free wound healing.1-4

The dense layer of Geistlich Bio-Gide® Compressed is more cell-occlusive than the porous layer. Therefore, we advise to place the membrane as described in the IFUs. However, it is not necessary to remove the membrane.
Clinical performance of Geistlich Bio-Gide® Compressed is regarded the same as Geistlich Bio-Gide®. Various studies have shown that membranes of the Geistlich Bio-Gide® product family support excellent wound healing1-3 and predictable bone regeneration4.

Penetration of the membrane by blood and exudate during the surgery allows excellent adhesion of the membrane to the defect. Fixation of the membrane with sutures or pins is possible due to its high tensile strength. Fixation may be indicated to avoid membrane displacement due to shear loading or mobilization.
Both Geistlich Bio-Gide® Compressed and GeistlichBio-Gide® are intended to be used as barrier membranes in theregeneration of bone defects, for example in the context of Guided Bone Regeneration, for delayed or immediate augmentation around implants, reconstruction of the alveolar ridge, filling bone defects in the maxillofacial area and cleft closure surgeries. For further details, please consult the Geistlich Bio-Gide® and Geistlich Bio-Gide® Compressed IFU.
Geistlich Bio-Gide® Compressed has a smoother surface, a firmer feel and is easier to cut compared to Geistlich Bio-Gide®. Therefore, it offers an alternative handling for those dentists who prefer a firmer membrane. Geistlich Bio-Gide® Compressed is available in the sizes 13 x 25 mm and 20 x 30 mm. Availability may vary from country to country.
Geistlich Bio-Gide® Compressed y Geistlich Bio-Gide® están destinados a utilizarse como membranas de barrera en la regeneración de defectos óseos, por ejemplo en el contexto de la regeneración ósea guiada, para el aumento diferido o inmediato alrededor de implantes, la reconstrucción de la cresta alveolar, el relleno de defectos óseos en la región maxilofacial y las intervenciones de cierre de fisura palatina. Para más detalles, consulte las instrucciones de uso de Geistlich Bio-Gide® y Geistlich Bio-Gide® Compressed.
La capa compacta de Geistlich Bio-Gide® Perio es menos permeable a las células que la capa rugosa y porosa. Si la membrana se aplica con los lados invertidos, la integración de las células óseas puede producirse con bastante más lentitud. Sin embargo, no es necesario retirar la membrana.
In general, Geistlich Bio-Gide® Shape is based on the Geistlich Bio-Gide® Perio technology to facilitate application comfort. For easier handling, the membrane is pre-cut to a shape that fits for extraction sockets. This also reduces your preparation time.
The use of Geistlich Mucograft® Seal and Geistlich Bio-Oss® Collagen is recommended in extraction sockets with intact buccal bone walls.1

The membrane should be placed inside the alveolus or outside (between the bone and the soft-tissue). From the convenience point of view, it might be easier to place Geistlich Bio-Gide® Shape inside the alveolus.
The long strap of the Geistlich Bio-Gide® Shape should be placed to cover the bony defect of the socket, if present. Thereby the dense surface should face towards the soft tissue, and the rough side should face the defect.
To close the extraction socket, both lateral wings of the Geistlich Bio-Gide® Shape membrane should be tucked underneath the mucosa, located mesially and distally of the socket. The upper wing should be tucked lingually / pallatinally in-between the soft tissue and bone wall.
Loading with minimal pressure can be done immediately after surgery, taking into account the swelling due to the intervention. Loading by applying pressure can be performed as soon as the site has healed 3-8 weeks after grafting and should not be delayed more than 3 months. This might be beneficial for conditioning the new soft-tissue and favoring its maturation based on experience from clinical studies.
The result of the whole remodeling process of Geistlich Fibro-Gide® is the formation of new soft-tissue (connective tissue). Animal models have shown good integration of Geistlich Fibro-Gide® into the surrounding soft-tissue without formation of scar tissue.
It is important to adjust the size of Geistlich Fibro-Gide® to the dimensions of the defect site, taking swelling into consideration, in order to ensure tension-free wound closure. Slight over-augmentation with Geistlich Fibro-Gide®, on the contrary, might be needed (similar to Guided Bone Regeneration), but tension-free wound closure is key.
Geistlich Fibro-Gide® is intended to be used for soft-tissue regeneration at the alveolar ridge. Indications of Geistlich Fibro-Gide® are insufficient soft-tissue volume and recession defects.
Geistlich Fibro-Gide® is a porcine, porous, resorbable and volume-stable collagen matrix specifically designed for soft-tissue regeneration. The matrix is made of reconstituted collagen undergoes smart chemically cross-linking to improve volume stability of the device while maintaining its excellent biocompatibility.
Animal models have shown good integration of Geistlich Fibro-Gide® into the surrounding soft-tissue combined with the ability to degrade and be replaced by connective tissue while maintaining three dimensional volumetric stability over time.
Geistlich Fibro-Gide® is an alternative to autologous connective tissue grafts (CTG) for soft-tissue volume augmentation around dental implants and natural teeth. Geistlich Fibro-Gide® obviously has the advantage of reducing patient morbidity since there is no additional harvest site. Furthermore, there is no risk of necrosis when using Geistlich Fibro-Gide® compared to CTG.
Geistlich Fibro-Gide® is ready to be applied to the defect and does not need pretreatment or conditioning before application. Geistlich Fibro-Gide® possesses excellent hydrophilic characteristics that lead to a rapid hydration of the collagen matrix (patient’s own blood and/or sterile saline). When applied dry to the defect site, the matrix will hydrate easily by soaking up patient’s own blood and/or sterile saline very fast.
Geistlich Fibro-Gide® can be applied either in a dry or wet state subject to individual preference: pre-wetting can be done with blood and/or sterile saline. Geistlich Fibro-Gide® can be cut and trimmed both in a dry or wet state, using scissors and/or a scalpel. The scalpel is recommended for dry handling. Using a scalpel will help to obtain smooth edges and tapers for improved wound adaptation and precise fit of the matrix.
The device will gain approx. 25% in volume once wet. This increase in volume has to be taken into account when deciding upon final dimensions. A generous flap design is the key to full submersion of the matrix.
Use your preferred flap design. A generous preparation of the flap is key to promoting successful healing by complete coverage of Geistlich Fibro-Gide® (submerged healing). Different surgical techniques, such as tunneling and/or envelope techniques are currently being clinically tested (not all under studies).
Clinical experience has shown that tension-free wound closure is a key factor in preventing dehiscence. In open flap procedures for augmentation at the alveolar ridge a horizontal mattress suture is recommended to stabilize the matrix (5.0-6.0). In recession coverage single sutures (7.0) have been used for stabilization. Suturing of Geistlich Fibro-Gide® to the wound bed is not necessary due to its excellent hydrophilicity and adaptation.
A tension-free closure of the flap is key to a successful and complication-free healing and avoidance of any dehiscences during the healing phase. Please avoid compression of Geistlich Fibro-Gide® at the defect site.
After treatment with Geistlich Fibro-Gide®, please follow the same postsurgical management that is usually applied with connective tissue grafts.

Clinical studies have shown a physiological increase in thickness when using CTG as the gold standard of 0.35 to 3.2 mm. Clinical studies have shown that treatment with Geistlich Fibro-Gide® results in an increase of 1-2 mm of thickness which is equivalent to results obtained with CTG. Geistlich Fibro-Gide® is provided with a thickness of 6 mm which gives freedom to the surgeon to trim it to the desired size and to use the collagen matrix for thickening of tissues under pontics where more volume might be required. For lateral soft-tissue augmentation, it is recommended to reduce the thickness of Geistlich Fibro-Gide® in order to achieve a tension-free, primary wound closure.

It depends on the indication:
1. Gain of keratinised tissue: Geistlich Mucograft® should be applied on a periosteal bed1,2 since blood supply is important. In open healing, the blood is supplied through the edges of the device from the surrounding tissue and from the periosteum.
2. Recession Coverage: Geistlich Mucograft® can be used partially or completely over bone.3-5 Blood is supplied through the edges of the device from the surrounding tissue and from the flap covering completely the matrix.
