Depending on the size of the defect between 1.5 to 4 cc of Geistlich Bio-Oss® granules are needed, or 3cc in average. This is equivalent to two 1.5cc Geistlich Bio-Oss Pen® with large granules or three 1cc Geistlich Bio-Oss Pen® with small granules.
No. Geistlich Bio-Oss® Collagen is a mixture of 90% Geistlich Bio-Oss® spongiosa granules and 10% highly purified porcine collagen in a block form. Geistlich Bio-Oss® is a natural bone mineral of bovine origin. The collagen facilitates adaptation of the Geistlich Bio-Oss® to the defect site.
The collagen in Geistlich Bio-Oss® Collagen does not function as a membrane. When the socket is not intact, it is recommended to use a membrane to receive optimal results1.

The compact layer of Geistlich Bio-Gide® exhibits higher cell occlusiveness than the rough, porous layer. If the membrane is applied side-inverted, integration of the bone cells may take place rather more slowly. However, it is not necessary to remove the membrane.
No, autoclaving or hot-air sterilization irreversibly destroys the collagen structure. The physical properties of the membrane are changed and the consistency of the product becomes like parchment paper. The membrane may not be used.

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.
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.
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.
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.

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.
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.
The surface of Geistlich Bio-Gide® Perio has been made firmer when dry to facilitate periodontal applications. Second, the outer blister pack of Geistlich Bio-Gide® Perio includes four sterile water repellent templates. These can be placed repeatedly in the region of the defect to allow customization of the template before cutting the membrane to the precise shape.

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.
Place the membrane without pre-wetting within the extraction socket. 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.
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 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.
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.
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® 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.
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.
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.
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.
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.
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.
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.
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.
Geistlich Mucograft® consists of porcine collagen and is specifically designed for soft-tissue regeneration. The matrix is built up of a compact structure that gives stability while allowing open healing, and a spongy structure that supports blood clot stabilisation and ingrowth of soft-tissue cells.
The collagen of Geistlich Mucograft® will be replaced by newly formed soft tissue. The matrix is rapidly vascularized and colonised by soft-tissue cells. This leads to a good integration of the matrix without any signs of foreign body reaction1,2.

Geistlich Mucograft® is ready to be applied to the defect and does not need pretreatment or moisture before application. Due to its excellent hydrophilicity, the matrix will hydrate quickly after implantation in the defect by soaking rapidly the patient’s blood.
Published data show different suturing techniques with Geistlich Mucograft®: non-resorbable1,2 and resorbable3, 0-51,2 and 0-64. There is no clinical evidence showing a benefit of one type of suture over another one, when suturing Geistlich Mucograft®.

The compact structure should face outward, away from underlying bone, with the spongeous structure facing the bone or soft-tissue wound bed. Neither clinical nor comparative data on inverted device performance is available for Geistlich Mucograft®.
In the majority of the individual cases treated thus far and for all the studies performed with Geistlich Mucograft®, one matrix layer was used. Presently, clinical data is not available to prove that several layers of the device outperform a single layer of Geistlich Mucograft®.
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.

It depends on the indication: 1. Gain of Keratinised Tissue: Open healing is recommended when Geistlich Mucograft® is used to increase width of keratinised tissue. The innovative design of Geistlich Mucograft® allows excellent healing in open healing situations1. 2. Recession Coverage: Geistlich Mucograft® should remain completely submerged under the flap to avoid premature resorption of the collagen.2-4 Direct blood supply is important.

Geistlich Mucograft® Seal is specifically designed for soft-tissue regeneration1. The collagen of Geistlich Mucograft® is specially processed to favour immediate blood clot stabilization. This leads to early vascularization1,3, facilitates soft-tissue cell ingrowth2 and good integration of the matrix with surrounding tissues2,3. In contrast to other collagen products in the market, Geistlich Mucograft® and Geistlich Mucograft® Seal are well scientifically documented and their clinical benefits are proven.

The resorption time of every biomaterial including Geistlich Mucograft® Seal depends on multiple factors: defect size, metabolism and general health of the patient, etc. On the other hand, to determine an average resorption time of Geistlich Mucograft® Seal in humans, biopsies would be needed of the healing soft tissues after tooth extraction at different time points. This procedure is obviously not ethical and thus the average resorption time cannot be measured. However, single histologies indicate that after 8 weeks Geistlich Mucograft® is completely integrated into the newly formed soft tissue.
Geistlich Mucograft® Seal needs the support of Geistlich Bio-Oss® Collagen underneath for a good ridge preservation of the soft and the hard tissues. After 8 weeks, the soft tissues are healed but the mixture of the blood clot, Geistlich Bio-Oss® Collagen and the newly forming bone is still soft. Nevertheless the implant can be drilled carefully into the socket and the remaining Geistlich Bio-Oss® Collagen will favour the volume preservation of the ridge.

The compact structure should face outward, away from underlying bone, with the spongeous structure facing the bone or soft-tissue wound bed. Geistlich Mucograft® Seal spongeous structure is striped for easier differentiation of the two sides. The striped spongeous structure should face the bone.
Geistlich Mucograft® Seal should be sutured using non-resorbable sutures, not glued1. The close adaptation of the device to tissue borders can be accomplished by single interrupted sutures, double interrupted sutures, cross sutures, or sling sutures1. The finest possible suture material comfortably used by the surgeon should be selected: for single interrupted sutures, the 6.0 or 5.0 suture size is recommended; for cross-suturing, a 5.0 suture size is appropriate1.

Yes. Geistlich Mucograft® Seal is an alternative to autogenous soft-tissue graft for soft-tissue regeneration. Geistlich Mucograft® Seal does not require pre-hydration or washing. It should be handled and applied in a dry state. Before applying Geistlich Mucograft® Seal, adjacent soft-tissue margins should be de-epithelialized. This allows epithelial cells to freely migrate from the soft-tissue borders into the matrix.
Investigators still cannot agree on the importance of the presence of keratinised tissue. Various studies have shown, however, that lack of keratinised tissue around implants is associated with
Gingival recession over a period of five years1
Soft-tissue attachment loss2
Increased plaque accumulation lingually1
Inflammation of the soft tissue2
More frequent bleeding1
