Experience the resorbable collagen membrane with outstanding handling properties
creos xenoprotect is a resorbable dental membrane. A resorbable collagen membrane is used for guided bone regeneration (GBR) and guided tissue regeneration (GTR) procedures.
It's composed of a network of interwoven, highly purified porcine collagen and elastin fibers, providing the membrane with high mechanical strength.
The fiber mesh holds the bone graft material securely in place, preventing undesired soft tissue from migrating into the bone augmentation site during bone healing.
A noticeable difference when applying the creos xenoprotect membrane is the ease of repositioning and unfolding as it doesn't become sticky when hydrated. It's rehydrated within seconds and adheres well to the defect shape. What's more, the membrane can be cut and pre-shaped according to the specific defect without having to consider any major size increase when moistened.1
creos xenoprotect is highly tear resistant due to its high mechanical strength, and its elastin fibers make the membrane stretchable.2 This makes it easy to stretch over the defect area and suture without fear of rupturing the membrane.
In clinical studies, creos xenoprotect demonstrates good results in the treatment of dehiscence defects3 and in horizontal ridge augmentation procedures.4,5 In both applications, creos xenoprotect facilitates bone gain and supports successful implant placement.3,4,6
In preclinical studies, creos xenoprotect has been shown to play an active role in regulating bone-healing dynamics in vivo.7 In addition, as a natural collagen membrane that is not subjected to chemical cross-linking, creos xenoprotect exhibits an enduring resistance to degradation in vivo.2
In clinical studies in patients with dehisced implant sites and horizontal bone defects, use of creos xenoprotect is associated with favorable healing with no major complications.3,4,5 Observed rates of wound dehiscence and membrane exposure are low when creos xenoprotect is used in guided bone regeneration.3,4,5
Whether larger bone augmentations or smaller periodontal defects, the optimal fit can be found without extensive trimming. This limits waste and minimizes costs for you and your patients. creos xenoprotect is available in three different sizes: 15 x 20 mm, 25 x 30 mm and 30 x 40 mm.
Situation: Fractured first maxillary left premolar, tooth extraction indicated.
Solution: The defect is filled by using bovine hydroxyapatite. A creos xenoprotect collagen membrane is applied to cover the defect. After three months, reopening of the treated area shows complete regeneration of the initial defect.

Situation: Extraction of two lower right molars indicated, vertical bone defect at first molar.
Solution: GBR procedure using creos xenoprotect collagen membrane and simultaneous implant placement with a Brånemark System MK IV implant. Restorative solution using a NobelProcera Titanium Abutment and a screw-retained crown.

Situation: Missing teeth 46, 47. Late implant placement, bone quality D1, poor bone quantity.
Solution: Horizontal and vertical augmentation by GBR using creos xenoprotect collagen membrane with “tenting screw technique”.

Situation: 7 mm buccal probing and mild root resorption at upper central incisor (tooth #21).
Solution: Removal of hopeless tooth with immediate placement of NobelActive implant, bone grafting with a mix of autogenous bone and deproteinized bovine bone matrix (DBBM), covered by a creos xenoprotect collagen membrane.

Situation: Periapical infection and an open fistulous track toward the root of upper central incisor (tooth #21). Presence of a perio-endo lesion and tooth is extracted. Loss of the buccal bone plate so a lateral bone augmentation procedure is indicated.
Solution: Deproteinized bovine bone mineral (DBBM) is used as scaffold and creos xenoprotect as a protective barrier. An implant is placed after six months of uneventful healing.

Situation: Trauma on both upper central incisors in 1994. Teeth were re-implanted and extraction done in November 2012.
Solution: Horizontal ridge augmentation using processed allogenic bone graft and a creos xenoprotect collagen membrane. Placement of two NobelActive implants after six months of healing.

“I really like the handling of the material. The fact that it doesn’t lose its shape when you place it, is a great benefit. It gives you the possibility to take out the membrane and trim it. After a minute or so, when it is soaked, it attaches very nicely to the bone surface and no fixation seems to be necessary.”
“It is a thin, easy to handle and quickly moistened membrane that maintains its properties as a barrier. It allows suturing and/or tag fixation and is easily adapted to the bone defect.”
“For over a decade I have used collagen membranes to achieve excellent results. Each type of membrane offered varying benefits. Nobel Biocare has managed to integrate most of them. I was surprised by its rapid and uniform hydration. It is easy to cut and it does not fold itself together. It is ideal for maxillary sinus lift and bone regeneration.”
“I like the membrane because it's very easy to handle compared to other membranes I’ve used. The most important thing for me is the extended resorption time – the membrane stays in place longer.”
Private practice, Antwerp, Belgium
“We have better results with creos xenoprotect than with the membranes we have used before. What I like is that the handling is very easy. The mechanical stability is very high and when it is rehydrated it adapts very well to the underlying bone.”
“My early experience with this membrane, both intra-operatively and post-operatively, has been positive. Post-operatively, I like the fact that I see very little inflammation. 10 days post suture removal, the tissues are looking pink. If you're using GBR in conjunction with your implant therapies, I would recommend this membrane."
“I was pleasantly surprised to still find remnants of the creos xenoprotect membrane after six months. This long degradation time provides a greater chance of success.”
